The Impact of Artificial and Natural Additives in Meat Products on Neurocognitive Food Perception: A Narrative Review

The holistic sensory experience creates a unified perception that influences consumer memory. Consumer interest in clean label products underlines an accelerated trend towards products without artificial additives. From a sensory point of view, food appeal is significantly influenced by how additives actively participate in the organoleptic properties of the final product. This research aims to shed light on the impact of artificial and natural additives in meat products on neurocognitive food perception, which is essential for understanding how they influence the consumer’s final decision and direct food trends. Different neural mechanisms involved in multimodal sensory integration confirm differences in perception of meat products containing artificial and natural additives. Analysis confirms that neurocognitive perception integrates organoleptic sensations to form a complete sensory experience. The encephalon simultaneously processes multimodally integrated stimuli from organoleptic properties, reaching the orbitofrontal cortex and other regions involved in the neuroprocessing of the final product. The reformulation and development of meat products need a detailed analysis of the impact of additives on sensory properties contributing to the shaping of consumption trends.

Biotechnology Advances in Natural Food Colorant Acylated Anthocyanin Production

ABSTRACTThe food application of natural blue colorants such as acylated anthocyanin is becoming increasingly popular due to their safety, nutritional value, organoleptic attributes, and more pH/thermo‐stable properties compared to nonacylated anthocyanins. However, it is a great challenge to obtain enough acylated anthocyanins to meet market demand, rather than readily available in nature from edible fruits and vegetables. In this review, the acylated anthocyanins in food crops, the efficient and eco‐friendly extraction of food‐grade acylated anthocyanins, and their potential application in intelligent packaging are extensively summarized. Subsequently, the plant anthocyanin acyltransferases (AATs) are also comprehensively summarized. The strategy of functional optimization of AATs through computational or artificial intelligence–based protein‐directed evolution is described and suggested. Additionally, the advantages and disadvantages of acylated anthocyanins generated in microbes and plant suspension cells are extensively compared, and the chassis selection of engineering acylated anthocyanins is discussed. Finally, the approaches and strategies of metabolic engineering to enhance the yield of acylated anthocyanins in plant suspension cells are also described and discussed. Taken together, this review provides a roadmap or strategy for the production of acylated anthocyanins to meet the increasing market demand in future food industry.

Shelf Life and Organoleptic Attributes of Multifruit Smoothies Treated by Combined Mild Preservation Technologies

The application of high hydrostatic pressure and mild heat treatment represents preservation processes for extending the shelf life of food products without compromising their quality. The combination of these physical methods at lower applied levels represents a promising approach to preserving the quality of treated products. This study aims to investigate the impact of combined treatments on the quality and storage stability of strawberry, banana, almond milk and avocado smoothies. The total colony count, electronic nose and tongue signals, colour, viscosity and sensory properties were examined over a 14-day storage period at 6 °C. The combined treatments were found to be effective in reducing the total colony count. During the sensory analysis, the impact of storage was the most prominent factor. Both the treatments and storage conditions significantly affected the colour characteristics of the samples. The smoothie samples exhibited pseudoplastic flow behaviour. Both applied treatments resulted in enhanced texture stability of the samples during the storage period. The electronic tongue and nose could differentiate between groups of fresh and stored samples, as well as between control and treated samples.

Improving the Dietary Fiber Content of Tapioca Using Corn Fiber as a Fiber Supplement

This research aims to enhance the dietary fiber content of locally produced cassava (manihot spp) food, tapioca, by incorporating corn (Zea mays) as a fiber supplement. Tapioca was prepared by grating cassava into coarse particles and washing it with water to remove starch. Starch analysis was conducted using a spectrophotometric method, revealing a starch content of 70.21% before washing and pressing, and 64.95% after washing and pressing. The tapioca samples were blended with corn fiber (obtained from wet milling of corn seeds that were destarched and dried in the sun) in various ratios: Sample A (100% pure tapioca), Sample B (90% tapioca, 10% corn), Sample C (80% tapioca, 20% corn), Sample D (70% tapioca, 30% corn), and Sample E (60% tapioca, 40% corn). Proximate analysis was performed on the blends to assess the increase in fiber content and any other changes introduced by the corn. Organoleptic properties such as binding, crunchiness, and color were also evaluated. The analysis revealed that the fiber content of tapioca increased from 2.7% to 3.95%, with the blend containing 70% tapioca and 30% fiber showing the highest increase in fiber content and good binding properties.

Effects of Active Compounds and Their Metabolites Associated with Coffee Consumption on Neurodegenerative Diseases.

Coffee is one of the most known and consumed beverages worldwide. Only three species are used in commercial coffee production, i.e., Coffea arabica L. (Arabica coffee), Coffea canephora Pierre ex A. Froehner (Robusta coffee), and Coffea liberica Hiern (Excelsa coffee). The world population consumes approximately two billion cups of coffee per day, making it an important commercial resource of bioactive compounds in world markets. High interest in coffee consumption described in the literature is not only due to its organoleptic properties (for example desirable bitterness, amount of flavours, and aromas) but also for its ability to stimulate the central nervous system.It is now known that there are more than 1000 compounds in coffee beverages, several of which have a bioactive activity. Recent studies show that consuming three to four cups of coffee per day, i.e. moderate consumption according to the European Food Safety Authority, may be beneficial for health.The main objective of the proposed review is to provide a comprehensive overview of bioactive compounds in coffee and other caffeine-containing beverages and their effects on neurodegenerative proteinopathies.

Can Sustainable Food from Edible Insects Become the Food of the Future? Exploring Poland’s Generation Z

This study addresses a research gap by examining the attitudes and interest of young Polish consumers in new foods containing insects. The results of the survey, which are presented in this article, were obtained as part of an inter-university project conducted at five Polish higher education institutions (N = 1063). The survey was conducted using the indirect interview method via an online platform (CAWI). This study aimed to assess attitudes, behaviours and intentions to purchasing insect foods, as well as factors influencing the selection of new foods containing insects and product preferences for such foods. The analysis revealed no statistically significant differentiation in consumer behaviour and declared intentions towards insect foods based on gender or place of residence (p > 0.001). Our results revealed correlations between the level of neophobia and negative attitudes among young consumers towards insect products, albeit weak in nature. The exploratory factor analysis suggested that the assessment of factors influencing the purchase of insect products may be based on a small number of dimensions, which were not found to be correlated, as follows: “Health and Environmental Concern”, “Organoleptic Attributes” and “Circumstantial Influences”.

Pemanfaatan kulit buah kakao pada proses alkalisasi biji kakao serta pengaruhnya terhadap mutu kakao bubuk

The problem facing the industry of cocoa powder in Indonesia is that cocoa powder on the market has a high fat content, high acidity, a color quality that is not comparable with imported cocoa products, and a variety of flavors and aromas. Alkalization is a method that can handle these problems. Alkalization is a process to improve the quality and appearance of cocoa powder. Alkalization is carried out by adding potassium, magnesium, and others to cocoa. High potassium content can be found in cocoa pod husks. Cocoa pod husks are the main by-product from the cocoa industry, constituting 67 – 76% of the cocoa fruit weight. Cocoa pod husk contains potassium, fiber, and antioxidants that function as biomaterials for food and non-food products. The aims of the study were to determine and evaluate the quality of cocoa powder with the effect of alkalization treatments using cocoa pod husks. The study was carried out at The Indonesian Industrial and Beverage Crops Research Institute, Sukabumi, West Java, from January to June 2022. This study was designed in a factorial completely randomized design. The first factor was the alkaline material, which consisted of two levels (cocoa pod husk and baking soda). The second factor was the concentration, which consisted of 3 levels (1%, 2%, and 3%). The variables observed were the L*, a*, b*, moisture content, ash content, fineness, pH, fat content, protein, antioxidant activity, and organoleptic properties. The results showed that the alkalization process with alkaline material from cocoa pod husk and a concentration of 2% is the best quality characteristic of cocoa powder in accordance with SNI 01-3747-2013.

Lemongrass-Synthesized Silver Nanoparticles as Preservatives of Fermented Locust Beans

Fermented locust beans (FLB), produced from Parkia biglobosa (Mimosaceae-Fabaceae), are used in many parts of West Africa, including Nigeria, as condiments to enhance the taste and nutritional quality of foods. These benefits are, however, marred by the short shelf-life of FLB. Traditional preservative methods and the use of chemicals have their shortcomings. This study, therefore, investigated the effectiveness of lemongrass-synthesized silver nanoparticles (LSSNP) as a preservative of FLB. The LSSNP was prepared, characterized, and used to treat fresh FLB at 10% v/w. Dynamic light scattering analysis revealed a mean hydrodynamic size of 89 nm for the LSSNP, while transmission electron micrograph showed roughly spherical particles with an average size of 100 nm. Bacillus licheniformis KGEB16, B. licheniformis APBSWPTB167, B. licheniformis PS4, B. subtilis CICC10148, and Enterobacter xiangfangensis M5S2B6 isolated were susceptible to LSSNP with comparable zones of inhibition to reference antibiotics. A significant reduction of the microbial load of FLB by up to 63.7% due to LSSNP treatment was achieved. The organoleptic and proximate properties of LSSNP-treated FLB were preserved. A histo-morphological study showed normal hepatic architecture in rats fed with LSSNP-treated FLB. This study showed that LSSNP possesses antimicrobial properties and can be employed as a green and safe alternative for the preservationof FLB.

Impact of tiger nut milk as a substitute for cow milk on the rheological, physiochemical, and organoleptic properties of functional ice cream

AbstractTiger nuts are an excellent food choice due to their rich mineral, fiber, and antioxidant content. Tiger nut milk was replaced by 25, 50, 75, and 100% of cow’s milk in the ice cream mixture. The impact of substituting cow milk with tiger nut milk on the physicochemical, rheological, and organoleptic properties of ice cream was examined. Adding tiger nut milk in a combination resulted ice cream mixes with more fiber and antioxidants and a lower protein and ash levels compared to the control (100% cow milk). Ice cream with tiger nut milk was higher in Fe and Zn than that of control. Dynamic viscosity values of ice cream mixes with tiger nut milk were decreased with increasing values of the applied shear rate compared to the control. All functional ice cream formulations with tiger nut milk showed higher specific gravity and melting rate with lower overrun percentages than the control. Regarding taste and flavor, structure, texture, and melting in the mouth, there is no appreciable difference between the T25, T50, and control treatments. Therefore, cow’s milk can be replaced with tiger nut milk up to 50% in the ice cream industry to raise the nutritional value and functional properties.

Nutritional and therapeutic properties of yoghurts can be enhanced by incorporating bioactive food components. The present study was focused on formulating a finger millet flour incorporated set yoghurt to deliver the inherent health benefits of finger millet to consumers in a ready-to-eat way. Ten yoghurt samples were formulated incorporating different percentages of finger millet flour. Physicochemical and microbiological properties of the yoghurts were evaluated. When considering organoleptic properties, 7% finger millet flour incorporated yoghurt was selected as the most preferable yoghurt among the tested finger millet flour incorporated yoghurts. It was complying with the physicochemical requirements and microbiological limits mentioned in the Sri Lanka Standard - Specification for yoghurts. Incorporation of 7% finger millet flour enhanced the nutritional composition of the yoghurt in terms of total dietary fibers (1.04%), total phenolic content (54.09 mg Gallic acid equivalents/100 g of yoghurt), total flavonoid content (8.00 mg Quercetin equivalents/100 g of yoghurt) and antioxidant properties including ABTS radical scavenging activity (190.81 mg Trolox equivalents/100 g of yoghurt) without affecting the sensory properties. Since it was formulated without adding gelatine, the 7% finger millet flour incorporated yoghurt is suitable for lacto-vegetarians. When stored in a refrigerator at 4 °C, the 7% finger millet flour incorporated yoghurt could be stored satisfactorily for four weeks. The finger millet flour incorporated yoghurt is capable of not only fulfilling the consumer demands for finger millet-based ready-to-eat foods and diversified yoghurt products, but also delivering additional health benefits, beyond the basic nutritional functions of a yoghurt, to consumers.

PENGARUH PENGGUNAAN KOAGULAN ALAMI SARI BELIMBING WULUH PADA TAHU PUTIH BERDASARKAN PERBEDAAN KONSENTRASI DAN LAMA PENGGUMPALAN

Tofu is a food whose process involves agglomerating soybean curd using coagulants, one of which is vinegar. In addition, from the other side, vinegar acid has shortcomings so that a natural coagulant substitute such as starfruit wuluh is needed. Belimbing wuluh one of the fruits that contains citric acid so that it can be used as a natural coagulant to replace vinegar, besides that it also contains oxalic acid, acetic acid, malic acid, formic acid, ascorbic acid and other compound components. This study aims to determine the effect of star fruit juice concentration and clotting time on the physicochemical and organoleptic properties of white tofu using star fruit as a coagulant. The method used was Randomized Group Design (RGD) using two factors, namely the concentration of Wuluh starfruit juice (factor 1) consisting of 4%, 5% and 6% and the coagulation activity (factor 2) consisting of 20 minutes, 30 minutes and 40 minutes. The testing parameters include protein content, fat content, moisture content, ash content, carbohydrate content, chewiness and organoleptic (scent, taste, color, texture and liking). The results of the analysis showed that there was an effect of the use of star fruit juice concentration and clotting time on protein in white tofu, which ranged from 3.50% - 6.77%; the range of water content ranged from 85.79% - 89.89%, chewiness was 3.08 N - 16.03 N. However, there was no significant effect on ash, fat and carbohydrates. As for the organoleptic test, the results showed a significant effect for scent parameters ranging from 2.80 (somewhat fragrant) - 4.05 (fragrant), color ranging from 2.45 (not bright white) - 3.45 (slightly bright white), texture ranging from 2.85 – 3,65 (slightly chewy) and liking ranging from 3.05 (slightly like) - 3.7 (like).

Stainless Steel Deposits on an Aluminum Support Used in the Construction of Packaging and Food Transport Containers

A series of chemical elements from the chemical composition of the packs of liquid food products migrate inside them or they combine with other chemical elements existing in the food, resulting in chemical compounds that worsen the quality of the food. In the present paper, layers of food stainless steel were deposited using thermal arc spraying on an aluminum alloy substrate to stop the migration of aluminum ions inside liquid food products. The physical-chemical and mechanical properties of the protection system: stainless steel layer used in the food industry (suggestively called: food-grade stainless steel)—aluminum substrate were investigated, and then the organoleptic properties of the food liquids that came into contact with the deposit were evaluated. It was found that food-gradestainless steel deposits have low porosity (3.8%) and relatively high adhesion and hardness, which allows complete isolation of the substrate material. The investigations carried out on the properties of food liquids that come into contact with the stainless steel deposit revealed the fact that it perfectly seals the aluminum start. The food-grade stainless steel coating (80T) was much better and safer for preserving dairy products maintaining a constant acidity up to 17 degrees Thorner, wines (with an average acidity of 3.5–4 degrees), juices (with natural pigments), and oils (with a good absorbance level correlated with clarity). This aspect suggests that the created system can be successfully used to manufacture containers for the transport of liquid products.

Enhancing the quality of wholemeal bread with chia, sesame, and rosehip: mathematical modelling and organoleptic analysis

In this paper, the research was conducted using mathematical modelling methods to improve the quality of the product. This study aimed to determine the optimum composite mixture for producing whole wheat flour by adding sesame seeds, chia seeds, and crushed rosehip. Following the mathematical matrix, 20 different samples have been baked. The basic criteria were porosity and specific volume. The results were entered into Exel to draw up a graph. According to the graphic analysis, the most optimal mixture in terms of the dry matter mass in the dough was as follows in %: rosehip - 1.1%, chia seeds - 1.5%, and sesame - 2.2%. The organoleptic and physicochemical properties of the resulting samples were later analysed according to the recipes based on the selected composition of seeds. By swelling the protein shells of chia and sesame in a humid environment, amino acids in the flour combine into a chain to form a skeleton. At the same time, the ascorbic acid in the rosehip binds with the carbon atoms in the chain, strengthening the framework. As a result, large amounts of gases formed in whole grain flours are trapped in these frames, increasing the porosity of bread by 21.8%, increasing the volume of production by 29.5%, absorbing proteolytic enzymes under the influence of globulins in chia grain, slowing down amino acid degradation, reducing moisture content by 3%.

Enhanced lutein and protein production with improved organoleptic properties in a novel yellow strain of Auxenochlorella pyrenoidosa mutant through atmospheric and room temperature plasma mutagenesis and norflurazon-based screening

To achieve the triple purpose of enhancing lutein and protein contents as well as improving organoleptic properties in biomass of Auxenochlorella pyrenoidosa mutant as raw material of future food, a novel yellow mutant, CX41 strain, was successfully selected through atmospheric and room temperature plasma (ARTP) mutagenesis and norflurazon-based screening. CX41 strain exhibited a significantly increased lutein (0.86 mg/g) and protein (49.00 % DW) contents simultaneously, while higher levels of total (33.47 % DW) and essential amino acids (14.78 % DW) were achieved with higher amino acid score (86.49) than that of the original A4-1 strain, a yellow and high protein mutant bred previously. Sensory evaluation showed that CX41 biomass has more comparable to A4-1, while in comparison to the wild type (WT), it has a more inclination towards roasted, with a fainter grassy, woody, rancid and fishy odor, and a significant improvement in taste is reflected by a decrease of 8.40 % in sweetness, a reduction of 14.86 % in bitterness, and an increase of 5.93 % in umami intensity. Metabolome analysis revealed that the superior sensory profile was due to the significantly reduced relative odor activity of β-ionone (herbaceous odor) and substances such as 1-octene, hexanal, 1-octen-3-ol, and heptanal (fishy and rancid odors). The extensive enhancements demonstrated CX41 biomass as a highly promising raw material with high nutrients of lutein and protein as well as excellent taste and flavor for future food application.
