Steering the path to safer food: The role of transformational leadership in food services to combat against foodborne illness

This paper zeroes in on transformational leadership as a central aspect in the promotion of food safety behavior within the food service industry of China, which is an important context in its fast-growing food sector. and global concern for foodborne diseases. Finding a void in the existing literature about the direct and indirect impacts of leadership styles on food safety practices, particularly in non-Western settings, our research examines how transformational leadership is related to food safety behavior via intrinsic motivation and food safety commitment of employees. Based on structural equation modeling through SMART-PLS, our study covers a comprehensive path analysis of the relationships between transformational leadership, employee intrinsic motivation, employee commitment towards food safety, and food safety behaviors among Chinese food service workers. The results show that transformational leadership has a noticeable direct impact on the food safety behavior of employees, that indirectly depends on intrinsic motivation and food safety commitment. The results highlight the role of leadership, which creates an organizational culture that values food safety and consequently decreases the risk of foodborne illnesses. The practical insights of our study are profound, providing a clear mechanism for food service organizations to improve food safety by providing leadership development and motivational programs. By filling different voids in the literature with empirical data from a non-Western context, our study not only furthers the theoretical body but also provides practical approaches to combating foodborne illnesses through effective leadership in the food service sector.

Screening Probiotics for Anti-Helicobacter pylori and Investigating the Effect of Probiotics on Patients with Helicobacter pylori Infection.

Probiotics are natural microbial agents with beneficial properties such as bacteriostatic and anti-infective properties. Lactobacillus plantarum Q21, Q25 and QA85, were isolated from the Chinese specialty fermented food "Jiangshui" and proved to be highly resistant to Helicobacter pylori (p < 0.0001). In vitro results showed that Q21, Q25 and QA85 strongly inhibited H. pylori and could specifically co-aggregate H. pylori in vitro (more than 56%). Strains have the potential to adhere to cells and hinder H. pylori colonization (p < 0.0001). To assess the anti-H. pylori efficacy of strains in vivo, volunteers were recruited and a self-controlled study of probiotic intervention was conducted. Compared to pre-probiotics, volunteers who took Q21, Q25 and QA85 for 1 month showed significant improvement in discomfort, a significant reduction in GSRS scores (p < 0.05), and modulation of inflammatory response (p < 0.05). Q21, Q25 and QA85 resulted in a decreasing trend of H. pylori load in volunteers (454.30 ± 327.00 vs. 328.35 ± 237.19, p = 0.06). However, the strains were not significantly effective in modulating the imbalance of the gut microbiota caused by H. pylori infection. In addition, strains affect metabolic pathways by increasing the levels of O-Phosphoethanolamine and other related metabolites, which may ameliorate associated symptoms. Therefore, Lactobacillus plantarum Q21, Q25 and QA85 can be regarded as a candidate probiotic preparation that exerts direct or indirect anti-H. pylori effects by inhibiting H. pylori activity and colonization, reducing inflammation and discomfort, maintaining homeostasis in the internal environment, affecting the metabolic pathways and repairing the body barrier. They can play a role in relieving H. pylori infection.

Beneficial In Vitro Effects of Polysaccharide and Non-Polysaccharide Components of Dendrobium huoshanense on Gut Microbiota of Rats with Type 1 Diabetes as Opposed to Metformin.

The extract of Dendrobium huoshanense, a traditional Chinese medicinal and food homologous plant belonging to the family Orchidaceae, was previously reported to have hypoglycemic and antioxidant effects. In this study, the direct effects of polysaccharide (DHP) and non-polysaccharide (NDHP) components of D. huoshanense, as well as its water extract (DHWE) were compared with that of metformin (an antidiabetic drug) on the gut microbiota (collected from fecal flora) of rats with streptozotocin-induced type 1 diabetes (T1D) using an in vitro fermentation method. The results showed that DHWE, DHP, and NDHP reduced pH and increased bacterial proliferation and short-chain fatty acid (SCFA) content in fermentation broth. DHWE, DHP, NDHP and metformin promoted the production of acetic and propionic acid, acetic acid, propionic acid and butyric acid, and propionic acid, respectively. DHWE, DHP, and NDHP reduced the abundance of Proteobacteria (subdominant pathogenic bacteria) and increased the abundance of Firmicutes (dominant beneficial gut bacteria). NDHP also reduced the abundance of Bacteroidetes (beneficial and conditional pathogenic). Metformin increased the abundance of Proteobacteria and reduced the abundance of Firmicutes and Bacteroidetes. At the genus level, NDHP promoted the proliferation of Megamonas and Megasphaera and decreased harmful bacteria (e.g., Klebsiella), and DHP increased the abundance of Prevotellaceae (opportunistic and usually harmless). By contrast, metformin increased the abundance of harmful bacteria (e.g., Citrobacter) and reduced the abundance of beneficial bacteria (e.g., Oscillospira). Our study indicates that DHWE, DHP, and NDHP are potentially more beneficial than metformin on the gut microbiota of T1D rats in vitro.

How Do Chinese Street Food YouTubers Robustly Communicate Cross-Cultural Tourism Destination?

The street food content of YouTubers is an intercultural communication message to promote Chinese culture to viewers around the world. This article aims to analyze cross-cultural interactivity in physical and online intercultural communication. The research uses a qualitative content analysis method continuously produced by non-Chinese-speaking YouTubers to communicate original Chinese culture to viewers outside China. The sample selection was determined using several search keywords on YouTube channels and 21 titles were selected in English, Indonesian, Malay, and French. Data were analysed by coding text, verbal, audio, and visual formats. Research finds that there is social learning about Chinese culture through street food and several other cultural dimensions, such as heritage, fashion, artefacts and history, Chinese language, and customs. YouTubers produce street food content by choosing Chinese culinary specialities to introduce to viewers. Viewers worldwide enjoy Chinese culinary delights in various places because overseas Chinese restaurants and street food are found in Southeast Asia, Europe, and America. Apart from watching online, viewers who are consumers also enjoy Chinese street food. Implications for the culture-based tourism industry are also discussed.

Can Non-farm Employment Improve Dietary Diversity of Left-Behind Family Members in Rural China?

Rural residents in China are still at risk of malnutrition, and increasing dietary diversity is crucial to improving their health. This study empirically analyzed the impact of non-farm employment on the dietary diversity of rural left-behind family members based on the China Land Economy Survey (CLES) 2020-2021 panel data at the farm and village levels. Dietary diversity was measured using the dietary diversity score (DDS) and the Chinese Food Guide Pagoda Score (CFGPS). The empirical results show that non-farm employment significantly enhances the dietary diversity of rural left-behind household members, including animal food diversity and plant food diversity. This result verifies the altruism phenomenon of non-farm employment in family diet. Mechanism analysis shows that non-farm employment enhances the dietary diversity of rural left-behind family members by increasing the level of family income, Internet accessibility, and family education. Heterogeneity analysis shows that non-farm employment does not enhance the dietary diversity of rural empty nesters and even has a negative impact. This reminds us that the nutritional health of rural empty nesters needs attention in the context of rapid urbanization and aging.

China and ancient cuisine: consumption of wild animals, western stereotypes and zoonoses

The purpose of this research is to highlight the characteristics of China's ancient cuisine, discuss the stigmas proffered by the Western media through image readings and, in the end, highlight the Western cultural horizon, with the demarcation of animal rights and concern about the emergence of zoonosis. The justification and problematic revolves around discussing the stigmas created about Chinese eating habits, the fakenews about their cuisine and the consumption of domestic and exotic animals. The methodology employed was descriptive and explanatory, as well as qualitative and bibliographical. The results obtained, through the analysis of a postcard and a virtual game about Chinese cuisine, show that there is a naturalization of stereotypes of the Chinese, something that is strongly linked to the scientific racism of the 19th century. We concluded that, although there are few outlets for these animals in China, where the number of consumers is small, it should be kept in mind that continuous contact with these species can lead to the emergence and spread of zoonoses.

Do firms hedge against political tensions? Evidence from Chinese food importers of Norwegian salmon

AbstractPolitical and economic tensions, which often jeopardise trade, are rising among the world's major powers, and countries like China are more frequently using food‐related trade actions to deal with deteriorating political relations. Using an event study approach, this paper investigates how importers respond to lasting political tensions by examining China's seafood importers' responses to the 6‐year Norway–China political tensions after Norway awarded Liu Xiaobo, a Chinese political dissident, a Nobel Peace Prize in 2010. Our results reveal firm‐level responses at both the intensive and extensive margins. At the intensive margin, firms that imported Norwegian fresh salmon before the sanction saw a 20% persistent decline in their fresh salmon import value and an 80% decrease in the import share of Norwegian fresh salmon products over our study period. At the extensive margin, we find a trade diversion effect that firms imported fresh salmon from Norway to other countries and regions, but also a consistent ‘political hedging’ effect 3 years after sanction with a 20% decline in the maximum import share from any particular country or region, even if not Norway.

Salt and Cardiovascular Disease

Heart disease is a leading cause of mortality and morbidity globally. Sedentary lifestyle, bad eating habits, and little to no exercise have led to an alarming rise of lifestyle-mediated diseases in recent times. Table salt is one of the staples of all our kitchens and dining tables. Salt contains almost 98% sodium chloride. The unregulated amount of salt in our diet has led to adverse cardiovascular consequences. Fast foods such as salted French fries and Chinese cuisine may contain as much as 7,000 mg of sodium in a single meal! The American Heart Association (AHA) recommends a daily intake of not more than 2.3 g of salt per day (roughly one teaspoon). For patients with hypertension, heart failure, or kidney disease, a lower daily cut-off of 1.5 g of salt has been proposed but is still under debate. There is conflicting evidence of going too low with salt restriction as recent studies have shown increased adverse events when salt was restricted to beyond the recommended per-day threshold. The DASH (dietary approaches to stop hypertension) diet is a novel dietary pattern that is recommended for patients with hypertension. The DASH diet is not a restrictive or short-term diet but rather a sustainable and balanced approach to eating. It promotes a wide variety of foods, focusing on whole, unprocessed options, and encourages portion control. Adhering to a DASH eating pattern by itself can lower the systolic blood pressure by 6–11 mm Hg. Reducing salt intake can be challenging, as salt is present in many processed and packaged foods, restaurant meals, and fast food. More than 70% of the salt we eat, according to the AHA, comes from processed, prepackaged, and restaurant foods. “Salt Lite” is often marketed as a healthier alternative for individuals looking to lower their sodium intake. It typically contains a blend of potassium chloride with sodium chloride and is hence not totally “sodium free.” Individuals considering the use of “Salt Lite” should be aware of its higher potassium content and should not use it if they have a kidney disease or are on drugs that can cause hyperkalemia. There is a common misconception that pink Himalayan salt is lower in sodium than regular table salt. However, both types consist of approximately 98% sodium chloride. Research has not shown that Himalayan salt has any unique health benefits compared to other dietary salts. It is hence imperative for all individuals to restrict dietary salt intake to the recommended levels—as a measure toward a healthy lifestyle as well as a therapeutic modality for those with established cardiovascular diseases.

GC-MS method for simultaneous determination and pharmacokinetic investigation of five volatile components in rat plasma after oral administration of the essential oil extract of Pogostemoncablin

Pogostemon cablin (PC) is a traditional Chinese medicine (TCM) and food as well as an important essential oil plant in China. PC essential oil exerts pharmacological effects such as anti-inflammatory, anti-oxidant, anti-platelet, anti-thrombotic, and anti-depressant. This study established a reliable and sensitive gas chromatography-mass spectrometry (GC-MS) method for the simultaneous determination of the pharmacokinetics of patchouli alcohol, β-elemene, β-caryophyllene, caryophyllene oxide, and farnesol in the plasma of rats after oral administration of PC essential oil extract. Using ethyl acetate to prepare the plasma samples, and p-menthone was used as the internal standard (IS). An HP5-MS column (0.25 μm × 0.25 mm × 30 m) was used for chromatographic separation, and detection was performed in selected ion monitoring (SIM) mode. The accuracies of intra-day and inter-day for all analytes displayed a range of −6.7 %–9.2 %, with precision below 12.5 %. Extraction recoveries for analytes ranged from 74.0 to 106.4 % and matrix effects ranged from 92.4 to 106.9 %. Stability results have demonstrated that the relative standard deviations (RSD) of analytes were below 12.1 %. Therefore, the developed GC-MS method successfully evaluated the pharmacokinetics of five volatile components in PC essential oil extract administered orally to rats.

Functional responses of two species of predatory mites (Acari: Phytoseiidae) to eggs and first-instar nymphs of Bactericera Gobica Logniova (Homoptera: Psyllidae).

The goji berry psyllid, Bactericera gobica Logniova (Homoptera: Psyllidae), is one of the most important pests on goji berry plants (Lycium barbarum L.), whose fruits are widely used in traditional Chinese medicine and food. However, chemical control is still the predominant control strategy of this pest. Recently, two species of predatory mites, Neoseiulus setarius Ma, Meng & Fan and Neoseiulus barkeri Hughes were found to be associated with B. gobica in China. To assess their predation potential against B. gobica, the functional responses of these two phytoseiid species feeding on different densities (2, 4, 8, 12, 16, 24 and 32 individuals) of B. gobica eggs and 1st instar nymphs were compared at a temperature of 25ºC ± 1º C. Logistic regression analysis revealed that both predatory mite species exhibited type Holling-II functional responses on eggs and 1st instar nymphs of B. gobica, with the predation number increased for both predators as the density of prey increased. Overall, N. setarius consumed more prey compared to N. barkeri across all levels of prey densities. Meanwhile, the highest attack rate (α = 0.0283), the lowest handling time (Th = 1.1324h prey- 1), and the highest estimated maximum predation rate (T/Th = 21.19 prey day- 1) were all observed for N. setarius fed with 1st instar nymphs of B. gobica. These findings suggest that it is worthy considering utilizing N. setarius and N. barkeri as candidate biocontrol agents of B. gobica, with N. setarius appearing to be a more effective predator than N. barkeri.

Preference of Chinese food production enterprises to government regulatory Information——A choice experiment approach

In recent years, despite the fact that the Chinese government is closely monitoring food safety, the perception of food production enterprises is not obvious. The reason is that information asymmetry hinders the effective transmission of regulatory information to food production enterprises. In the present research, a choice test is conducted to explore the preference of decision-makers for the information on government regulations in 224 food production enterprises with violations. It is found out that the decision-makers of food production enterprises have a strong preference for the regulatory information released by local governments. With a preference for reference information, compared to those who violate the law just once, decision-makers in food production companies that have several infractions exhibit a high "reference dependence" mentality. Also, the preference of different decision-maker characteristics shows an evident heterogeneity, as does the preference of various enterprises for the regulatory information about food safety. It is recommended that the government should improve the mechanism of disclosing the information about food safety, and focus on tailoring the information to different types of enterprises.

Discovery and identification of natural alkaloids with potential to impact insulin resistance syndrome in Cyclocarya paliurus. (Batal) leaves by UPLC-QTOF-MS combined with HepG2 cells

Cyclocarya paliurus (Batal.) leaves, which contain a range of bioactive compounds, have been used as a traditional Chinese medicine homologous food since ancient times. However, there is a paucity of literature on comprehensive studies of alkaloids in the leaves of Cyclocarya paliurus (Batal.). For the first time, this study aimed to discover and identify alkaloids extracted from Cyclocarya paliurus (Batal.) leaves by ultra-high performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UPLC-QTOF-MS). A total of ten alkaloids have been identified from Cyclocarya paliurus (Batal.) leaves based on accurate mass spectra (mass accuracy, isotopic spacing and distribution) and comparison to fragmentation spectra reported in the literature. In vitro, alkaloids alleviated insulin resistance by increasing glucose consumption and glycogen content in insulin resistance HepG2 cells. The RNA-seq and western blotting results showed that alkaloids could upregulate the expression of phosphatidylinositol 3-kinase (PI3K), and increase the phosphorylation of insulin receptor protein kinase B (AKT). This study not only clarified the chemical constituents and revealed that diverse alkaloids also presented from Cyclocarya paliurus (Batal.) leaves, also, it will provide chemical information on potential compounds for developing new drugs.

Determination of chloropropanol esters and glycidyl esters in nutritional foods by gas chromatography–tandem mass spectrometry based on acid hydrolysis and solid-phase extraction

This study presents a method based on acid transesterification and the purification by solid-phase extraction (SPE) coupled with gas chromatography–tandem mass spectrometry for quantifying 3- and 2-monochloropropanediol esters (3-MCPDE, 2-MCPDE) and glycidyl esters (GE) in nutritional foods. The fat was extracted by liquid–liquid extraction with petroleum ether and diethyl ether after the sample was hydrolysed with ammonia. Then the extract was purified by a SPE cartridge filled with the aminopropyl sorbents. It was demonstrated that the optimal elution volume for 3-MCPDE, 2-MCPDE and GE greatly depended on the sample matrix and varied from 6 to 12 mL for four different kinds of food matrices. All three analytes in the sample solution could be fully collected in the first 10–12 mL of eluate. By this way, monoacylglycerols commonly present in the samples were fully removed. Therefore, the overestimation of GE quantification was effectively eliminated. The modified analytical procedure was fully validated in a single laboratory and has been recommended as a Chinese Food Safety National Standard. In addition, two derivatisation agents, heptafluorobutyrylimidazole and phenylboronic acid, were proved to be equivalent in method accuracy and precision for the quantification of three analytes.

A frontier exploration of ancient craftsmanship: Effects of various tea products in traditional Chinese cuisine “tea flavored beef”

Modern science often overlooks to reveal the scientific essence of traditional crafts to promote their inheritance and development. In this work, five different types of tea products were prepared using the same variety of tea leaves referring to traditional methods. The analysis of their components and activities indicated that the processing reduced total catechin contents (from 172.8 mg/g to 48.2 mg/g) and promoted the synthesis of theaflavins (from 17.9 mg/g to 43.4 mg/g), reducing antioxidant and antimicrobial abilities of the resulting tea products. On this basis, the tea products were applied to “tea flavored beef” to reveal long-term effects. Within 15 days of storage, tea treatment showed remarkable antimicrobial and antioxidant activities on the beef. Also, the declines of sensory scores and texture of the treated beef were significantly suppressed. Meanwhile, protein degradation in the beef was inhibited, limiting the contents of various biogenic amines within relatively low levels.

Simultaneous determination of multiple components in rat plasma by UPLC-MS/MS for pharmacokinetic studies after oral administration of Pogostemon cablin extract.

Introduction: Pogostemon cablin (PC) is used in traditional Chinese medicine and food, as it exerts pharmacological effects, such as immune-modulatory, antibacterial, antioxidant, antitumor, and antiviral. Currently, the pharmacokinetics (PK) studies of PC mainly focus on individual components. However, research on these individual components cannot reflect the actual PK characteristics of PC after administration. Therefore, the simultaneous determination of multiple components in rat plasma using UPLC-MS/MS was used for the pharmacokinetic study after oral administration of PC extract in this study, providing reference value for the clinical application of PC. Methods: In the present study, a reliable and sensitive ultra-high performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) method was developed and validated for the simultaneous determination of 15 prototype components (vanillic acid, vitexin, verbascoside, isoacteoside, hyperoside, cosmosiin, apigenin, β-rhamnocitrin, acacetin, ombuin, pogostone, pachypodol, vicenin-2, retusin, and diosmetin-7-O-β-D-glucopyranoside) in rat plasma after oral administration of the PC extract. Plasma samples were prepared via protein precipitation using acetonitrile, and icariin was used as the internal standard (IS). Results: The intra-day and inter-day accuracies ranged from -12.0 to 14.3%, and the precision of the analytes was less than 11.3%. The extraction recovery rate of the analytes ranged from 70.6-104.5%, and the matrix effects ranged from 67.4-104.8%. Stability studies proved that the analytes were stable under the tested conditions, with a relative standard deviation lower than 14.1%. Conclusion: The developed method can be applied to evaluate the PK of 15 prototype components in PC extracts of rats after oral administration using UPLC-MS/MS, providing valuable information for the development and clinical safe, effective, and rational use of PC.

Guidelines for safe use of Polygoni Multiflori Radix

Polygoni Multiflori Radix is a Chinese medicine widely used in clinical treatment and preventive healthcare. However, recently there have been frequent reports of liver injury caused by Polygoni Multiflori Radix and its related preparations, and some patients have serious adverse outcomes, attracting wide attention worldwide. The risk of liver damage caused by preparations containing Polygoni Multiflori Radix or Polygoni Multiflori Caulis has been repeatedly reported by the Chinese Food and Drug Administration. Fortunately, substantial progress has recently been made in revealing the basic properties, main causes, material basis, and molecular mechanism of Polygoni Multiflori Radix-related liver injury. The basic characteristics and biomarkers of susceptible people have been identified, indicating that Polygoni Multiflori Radix has the risk of inducing liver injury only in a few specific populations and is safe for most populations. This study provides a scientific basis for a correct and objective understanding of liver injury caused by Polygoni Multiflori Radix, and a reasonable formulation of safe medication measures for Polygoni Multiflori Radix and related preparations. The China Association of Chinese Medicine organized experts in relevant fields across the country to draft and formulate the “Guidelines for Safe Use of Polygoni Multiflori Radix,” with the aim of helping the public and relevant institutions at home and abroad to scientifically understand, evaluate, and avoid the risk of liver injury; guide the rational use; protect the health rights and interests of consumers; and promote the healthy and sustainable development of Polygoni Multiflori Radix and related preparations. These guidelines were issued by the China Association of Chinese Medicine (No.T/CACM 1328-2019).

Revealing the Mechanism of Aroma Production Driven by High Salt Stress in Trichomonascus ciferrii WLW.

Douchi is a Chinese traditional fermented food with a unique flavor. Methyl anthranilate (MA) plays an important role in formation of this flavor. However, the complicated relationship between the MA formation and the metabolic mechanism of the key functional microorganisms remains unclear. Here, we elucidated the response mechanism of aroma production driven by high salt stress in Trichomonascus ciferrii WLW (T. ciferrii WLW), which originates from the douchi fermentation process. The highest production of MA was obtained in a 10% NaCl environment. The enhanced expression of the key enzyme genes of the pentose phosphate pathway and shikimic acid pathway directed carbon flow toward aromatic amino acid synthesis and helped sustain an increased expression of metK to synthesize a large amount of the methyl donor S-adenosylmethionine, which promoted methyl anthranilate yield. This provides a theoretical basis for in-depth research on the applications of the flavor formation mechanisms of fermented foods.

Agricultural socialized services and Chinese food security: examining the threshold effect of land tenure change

Revolutionary agricultural structural reforms in the supply chain and cutting-edge institutional mechanisms are pivotal in catalyzing a quantum leap in food production. China’s focus on achieving self-sufficiency in grain production for domestic security necessitates structural reforms in the agricultural supply chain and innovative institutional mechanisms. The emergence of socialized agricultural institutions plays a pivotal role in providing essential services to smallholder farmers. However, a dearth of studies evaluating the efficacy of these services in enhancing grain production exists. This study aims to fill this gap by analyzing provincial panel data from China spanning 2011 to 2020 to evaluate the impact of Agricultural Socialized Services (ASS) development levels on grain production. Employing panel and panel threshold models for empirical analysis, the research investigates how this impact varies between major grain-producing regions and non-major grain-producing regions. Findings indicate a significant positive effect of ASS on grain production, with a correlation coefficient of 1.3555. While its impact is less pronounced in grain-producing regions, it proves beneficial in non-grain regions. Moreover, the transfer of farmland use rights amplifies ASS’s influence on grain production, with a threshold value of 33.18%. The study concludes by outlining policy implications from various perspectives, providing practical recommendations for policymakers and stakeholders in the agricultural sector.

Full‐scale experimental and theoretical investigation on wall stress for underground ecological group tanks with four‐circle tangential connections

SummaryThe storage safety of edible oil is critical for global and Chinese food security. In this study, a practical underground four‐circle tangential group tank with the steel‐plate and concrete structure based on a grain storage warehouse was firstly introduced, and the measured hoop reinforcement stress of the outer tank wall is discussed. Secondly, a numerical model consistent with the practical underground group tank is established from the measured data. The distribution of the hoop reinforcement stress of the outer tank wall under earth pressure is extracted and analyzed thoroughly. Finally, formulas reflecting the properties of the hoop reinforcement stress distribution are presented based on the theoretical analysis, and their accuracy is verified by comparison with the measured data. It could be conducted from the experimental results and theoretical formulas that the outer tank wall is under compressive pressure station generally, and the compressive stress increases with the increasing of the ring angle until reaching a steady state. Moreover, the hoop stress curve follows a disproportional function approximately. The moment at 180° hoop with 1‐m plate belt follows the arc‐tangent function while the moment has a sudden‐change point at 120°, which has minor effect on the reinforcement of this tank wall. Consequently, additional attention should be paid to the effects of this sudden‐change phenomenon on the associated structures in in the process of designing of underground storage tanks.

Nature's beauty versus urban bustle: Chinese folk music influences food choices by inducing mental imagery of different scenes

Previous research has demonstrated that music can impact people's food choices by triggering emotional states. We reported two virtual reality (VR) experiments designed to examine how Chinese folk music influences people's food choices by inducing mental imagery of different scenes. In both experiments, young healthy Chinese participants were asked to select three dishes from an assortment of two meat and two vegetable dishes while listening to Chinese folk music that could elicit mental imagery of nature or urban scenes. The results of Experiment 1 revealed that they chose vegetable-forward meals more frequently while listening to Chinese folk music eliciting mental imagery of nature versus urban scenes. In Experiment 2, the participants were randomly divided into three groups, in which the prevalence of their mental imagery was enhanced, moderately suppressed, or strongly suppressed by performing different tasks while listening to the music pieces. We replicated the results of Experiment 1 when the participants' mental imagery was enhanced, whereas no such effect was observed when the participants' mental imagery was moderately or strongly suppressed. Collectively, these findings suggest that music may influence the food choices people make in virtual food choice tasks by inducing mental imagery, which provides insights into utilizing environmental cues to promote healthier food choices.
