Study on Association of Brand Identity Showing Limited Edition of Cosmetics: Focusing on domestic cosmetics

This With rapid changes in cosmetics market, a marketing strategy for brand survival has become essential. Under these circumstances, a limited edition could be a useful means to convey brand identity to consumers effectively. This study aimed to investigate the types of limited edition cosmetics and brand identity and analyze how brand identity is associated in the limited-edition package. For this, domestic cosmetics brands with high brand awareness and sales, which have been releasing limited editions ‘Sulwhasoo’, ‘The History of Whoo’ and ‘HERA’ were chosen. Through analysis of previous studies, a visit to their websites and a web search, the identities of the three cosmetics brands and limited edition packages for the past 5 years were divided by type. Then, cases were analyzed and reviewed by visual factor, and the results found the followings: First, the concept of each brand was used in designing a limited edition. Second, visual factors were efficiently applied to limited editions, having an influence on identity association. Third, even though colors varied depending on a type of the limited edition package, they were best used according to purposes and characteristics, associating image and identity colors according to each brand concept. As stated above, it was possible to associate brand identity in the concept and design of limited-edition cosmetics. It is anticipated that the study results would be helpful in studying relationships between limited editions and brand identity.

Performance of Structured Packing for the Deuterated Water Distillation Process at Above Atmospheric Pressure

The National Research and Development Institute for Cryogenics and Isotopic Technologies (ICSI) was established in 1970 for research focused the industrial pilot plant. ICSI was created with the purpose of developing the heavy water production technology needed mainly for the operation of the CANDU reactors that equip the Cernavoda Nuclear Power Plant in Romania. This technology has been demonstrated and has been successfully transferred to the heavy water production plant. The accumulated experience in the field of isotopic separation allowed for the development of a second pilot plant, also for the purpose of heavy water, but this time for the purpose of separating deuterium and tritium for the recovery of tritium, mainly from the tritiated heavy water of the CANDU reactors. This experimental pilot is based on a technology that combines two hydrogen isotope separation processes: liquid-phase water-hydrogen catalytic isotopic exchange and hydrogen isotope cryogenic distillation. The success of the separation process consists of the technical solution given to the exchange area, its geometry (distillation-isotopic exchange), and last but not least, the performance of the hydrophilic packing, respectively, of the catalyst. Thus, an extensive research program was initiated and carried out over many years for the development of mixed catalytic packages consisting of a hydrophobic Pt/carbon catalyst (with different concentrations of platinum up to 2%) and hydrophilic packing (stainless steel or phosphorous bronze) manufactured within ICSI and made in different configurations (successive layers, random or structured). This program for the improvement of catalytic packages continues by implementing new solutions regarding the improvement of materials that ensure a large contact surface between the liquid and vapors, respectively, vapor and gas, thus increasing the isotopic separation performance. This paper presents an experimental analysis of two types of hydrophilic stainless steel packings developed for the purpose of separating hydrogen isotopes by water distillation to be used in the manufacture of mixed catalytic packages for the catalytic isotopic exchange process. This paper refers to the experiments performed with deuterated water on the hydrophilic packing in conditions of total reflux. The experiments were performed on a column equipped with two types of hydrophilic packing.

Packaging performance evaluation and freshness intelligent prediction modeling in grape transportation

Vibrations during transportation inevitably lead to mechanical damage, endangering grape freshness and directly impacting their economic worth. While adequate packaging serves as a viable solution, current studies on packaging efficacy lack depth. Moreover, conventional methods for forecasting fruit freshness fail to accommodate the varying freshness levels of grapes across different packaging techniques. Consequently, a novel approach for predicting fruit freshness leveraging multi-sensing technology and machine learning algorithms is introduced. By reasonably evaluating packaging performance, the automation, intelligence, and accuracy of fruit freshness prediction are enhanced. Initially, critical control points in grape supply chain logistics were scrutinized using the HACCP method to identify key environmental parameters (vibration, temperature, and humidity) and their interaction with grape freshness. Subsequently, an environmental monitoring platform was devised for the grape supply chain, facilitating environmental surveillance under distinct packaging types (corrugated carton, foam box, plastic box, and inflatable package). Through a blend of environmental monitoring outcomes and physical-chemical indicators, the protective efficacy of diverse transport packaging was meticulously analyzed and appraised alongside finite element analysis. Notably, environmental data proved capable of characterizing grape freshness in lieu of quality data, with vibration metrics exhibiting strong correlations with quality metrics. Machine learning models were developed to predict grape freshness based on environmental cues, yielding prediction accuracies of 92.512% (SVM) and 94.334% (GA-ANN). The automated, non-destructive data acquisition and novel machine learning approaches offer a fresh avenue for evaluating packaging, predicting freshness, and managing food quality within grape logistics operations.

The Effect of Packaging Type and Storage Time on the Quality Characteristics of Chicken Nugget with Jack Bean (Canavalia ensiformis L.) Tempeh Flour Substitution

Chicken nuggets with jack bean tempeh flour substitution are a type of perishable food, thus having a short shelf life. The shelf life of chicken nuggets with jack bean tempeh flour substitution and its quality were affected by the storage conditions. This study aimed to determine the effect of packaging type and storage time during 20 days of cold storage on the quality characteristics of chicken nuggets with jack bean tempeh flour substitution. The research design consisted of two factors, the first factor was packaging type (nylon/polyethylene (PE), nylon-polyethylene (PE)/polyamide (PA), and polyethylene (PE)/polyamide (PA)) and the second factor was storage time (0 day, 5 days, 10 days, 15 days, and 20 days). The results showed that the packaging type and storage time significantly affected the quality characteristics of chicken nuggets with jack bean tempeh flour substitution. In conclusion, PE/PA was more effective in maintaining the quality characteristic of chicken nuggets with jack bean tempeh flour substitution on the 20th day of storage based on pH of 6.43, cooking loss of 9.85%, moisture content of 39.46%, protein content of 24.51%, and TPC of 5.36 log cfu/g. Meanwhile, the result of the sensory evaluation showed that scores for attributes were color 3.63, taste 3.5, texture 3.29, and overall 3.53 (like slightly) on the 20th day of storage.

Protein-Based Packaging Films in Food: Developments, Applications, and Challenges.

With the emphasis placed by society on environmental resources, current petroleum-based packaging in the food industry can no longer meet people's needs. However, new active packaging technologies have emerged, such as proteins, polysaccharides, and lipids, in which proteins are widely used for their outstanding gel film-forming properties. Most of the current literature focuses on research applications of single protein-based films. In this paper, we review the novel protein-based packaging technologies that have been used in recent years to categorize different proteins, including plant proteins (soybean protein isolate, zein, gluten protein) and animal proteins (whey protein isolate, casein, collagen, gelatin). The advances that have recently been made in protein-based active packaging technology can be understood by describing protein sources, gel properties, molding principles, and applied research. This paper presents the current problems and prospects of active packaging technology, provides new ideas for the development of new types of packaging and the expansion of gel applications in the future, and promotes the development and innovation of environmentally friendly food packaging.

Design and performance study of bone trabecular scaffolds based on triply periodic minimal surface method

Triply periodic minimal surface (TPMS) is widely used because it can be used to control the shape of porous scaffolds precisely by formula. In this paper, an I-wrapped package (I-WP) type porous scaffolds were constructed. The finite element method was used to study the relationship between the wall thickness and period, the morphology and mechanical properties of the scaffolds, as well as to study the compression and fluid properties. It was found that the porosity of I-WP type scaffolds with different wall thicknesses (0.1 ~ 0.2 mm) and periods (I-WP 1 ~ I-WP 5) ranged from 68.01% ~ 96.48%, and the equivalent elastic modulus ranged from 0.655 ~ 18.602 GPa; the stress distribution of the scaffolds tended to be uniform with the increase of periods and wall thicknesses; the equivalent elastic modulus of the I-WP type scaffolds was basically unchanged after the topology optimization, and the permeability was improved by 52.3%. In conclusion, for the I-WP type scaffolds, the period parameter can be adjusted first, then the wall thickness parameter can be controlled. Topology optimization can be combined to meet the design requirements. The I-WP scaffolds constructed in this paper have good mechanical properties and meet the requirements of repairing human bone tissue, which may provide a new choice for the design of artificial bone trabecular scaffolds.

Effects of moisture content and packaging on color stability of red pepper (Capsicum annuum L.) powder.

The color stability and quality changes of red pepper powder of various initial moisture content (7%, 10%, and 13%) and packaged with different materials, low-density polyethylene (LDPE) and nylon layered polyethylene (Ny/PE) film pouches or plastic and glass bottles, were compared during storage at 20°C for 126days. In the 7% moisture content sample packaged in LDPE film and plastic bottles, the L* and b*-values increased from 48.2 ± 0.7 and 15.4 ± 1.1 to 65.2-65.9 and 29.5-30.3, respectively, while the a*-value decreased from 26.1 ± 0.7 to 14.2-15.9, indicating a noticeable color change from red to orange. However, the decrease in the capsaicinoid and free sugar content of red pepper powder over time was found to have no significant correlation with moisture content and packaging type. As a result, the color change during the long-term storage of red pepper powder was greatly influenced by the initial moisture content and gas permeability of the packaging material.

Effects of Storage Period, Storage Conditions and Packaging Type on Maize Inbred Line Seed Qualities

The aim of this research was to study the effects of storage period, storage condition and packaging type on maize inbred seed qualities over 12 months storage. The experimental design was split-split plot with four replications. The study manipulated storage period (0, 3, 6, 9, and 12 months) as the main plot, uncontrolled storage condition (USC) and controlled storage condition (CSC) as the sub-plot, and packaging types including woven polypropylene (WPP), high density polyethylene (HDPE), polyamide (PA) with linear-low density polyethylene (LLDPE) and vacuum packing (PA + LLDPE + VACUUM, PLV) as the sub-sub plot. The results showed that the storage period did not affect seed germination; however, seed vigor decreased progressively with increased storage period. Seeds stored under USC exhibited lower moisture content, seed germination and vigor compared to those in CSC. Notably, seed vigor declined after the sixth month in USC storage. Among the packaging types, seeds in WPP had the lowest moisture content. Packaging type did not significantly influence seed germination throughout the storage period. However, different packaging types were able to maintain seed vigor for varying duration, especially for 6 months in PLV and 3 months in WPP packaging.

Free Drawing to assess food consumption information in comparison with the Free Listing: An intracultural study in Brazil with adolescents and dairy products

This study aimed to evaluate the Free Drawing method to assess food consumption information compared to the Free Listing method. Furthermore, the citation frequencies of dairy products consumed by adolescents were compared in Brazilian regions. Adolescents (14–17 years old, n = 265, n = 53 for each region, North, South, Northeast, Midwest, and Southeast regions) listed or drew the dairy products they consumed using Free Listing or Free Drawing. The contingency tables were constructed, and the cognitive saliency indexes (CSI) were calculated. Multiple Factor Analysis (MFA) was performed, and the RV indices were determined. The adolescents listed/drew 55 dairy products, grouped into 10 categories. The Free Listing method resulted in greater citation frequencies of dairy products. The Free Drawing method resulted in richer and more detailed information, with specifications of the type of product consumed within the category, flavor, type of packaging, and brand. The dairy products with the highest citation frequencies/CSI by adolescents were milk, cheese, and fermented milk. The South and Southeast regions observed greater citation frequencies and diversity of dairy products (prevalence in 6 categories). The CSI did not depend on the method, but it was affected by the region (p < 0.05). The sensory methods showed high similarity considering the categories of dairy products (RV = 0.80) and regions (RV = 0.79). It is concluded that the Free Drawing method proved to be an alternative to Free Listing for evaluating adolescents’ consumption information of dairy products in an intracultural study in Brazil.

The Effect of Temperature and Packaging on the Characteristics of Black Garlic During Storage

Abstract The transformation of garlic into black garlic is a simple process that yields products beneficial to human health. The curing process, conducted at a temperature of 60-90°C for 14 days in a rice cooker, alters the garlic’s physicochemical properties. The aim of this research was to study changes in physicochemical properties during storage using various packaging types and to determine optimal storage conditions. Two different types of packaging (PET jar and Aluminium pouch were used, at different temperatures (10, 25, and 30°C). The experimental results revealed that both temperature and packaging significantly influenced moisture content. Over the course of 42 days, the average increase in water content ranged from 13% to 22% for all treatments. During storage, the biological phenomenon still occurred, and it caused changes in chemical properties. It suggests that a biological process converting sugars into acids was underway, although the changes were insignificant when using PET jar packaging at a temperature of 10°C. In conclusion, this study found that moisture content, hardness, levels of reducing sugars, and acidity total, all changed during seven weeks of storage, and the content of reducing sugars decreased, whilst acidity total increased. The best storage conditions were determined to be at 10°C using PET packaging.

Transforming the preservation of tomato derivatives: Innovations in packaging and storage

The production and consumption of vegetables, such as tomatoes, have been growing in recent years, due to the combination of several factors, such as market demand, investment in research, education and awareness about health benefits, as well as government incentives and improvements in cultivation technology. The combination of these factors results in an increasing demand for products that offer health benefits, such as tomatoes rich in antioxidants, which help combat free radicals in cells. To maintain most of the nutritional and sensory properties characteristic of the fresh product, it is important to identify the parameters that will help in maintenance. Thus, the study aims to characterize the influence of different packages and storage times with the variables of tomato. The experiment examined the storage of two tomato derivatives (atomized tomato and chips) using various packaging types and storage durations. It utilized a factorial design (2 × 4) with an extra control treatment, comprising 3 replications. Packaging options included low-density polyethylene plastic bags and laminated plastic bags with aluminum foil, while storage durations ranged from 10 to 40 days. Parameters related to color (°Hue and chroma), flavor (pH, titratable acidity, soluble solids, and maturation index), and bioactive compounds (lycopene and β-carotene) of two tomato derivatives (atomized tomato and chips) were analyzed. After the analyzes, it was observed that the transparent package was the one that allowed the best conservation among the studied variables of the atomized tomato derivative, the same happened for the laminated packaging for the derivative chips. Regarding storage time, 20 days showed the best results regarding the conservation of flavor and bioactive compounds.

Measuring cells as a potential tool for the design and retrofit of columns with structured packings

In-depth experiments regarding the separation performance and pressure drop within a novel measuring cell, for the determination of structured packing characteristics for distillation processes, are presented. Furthermore, experiments with a pilot plant column (DN 250) were conducted and compared to the retrieved results from the measuring cell. Additionally, mass transfer coefficients were obtained from the conducted separation performance measurements of the measuring cell through a rate-based model. These coefficients were then used to predict the separation performance of a DN 250 column with an accuracy as good as using the Delft model for the prediction of the mass transfer coefficients. After introducing a maldistribution factor, the prediction of the separation performance of the DN 250 column with the measuring cell mass transfer coefficients could be significantly improved. Changing the packing type within the measuring cell revealed that the measuring cell can give reliable and reproducible results for packings with specific surface areas of 500m2m−3 and 250m2m−3, while at the same time investigating a close boiling system. The presented results indicate that the measuring cell is a promising tool for supporting the retrofit and design of columns with structured packings.

Investigating the impact of common migration substances found in milk packaging on proteases: A multispectral and molecular docking approach

The effects of common migration substances in milk packaging on digestive protease were studied. We choose the common migrants found in eight types of multi-layer composite milk packaging. Enzyme activity experiments revealed that pepsin activity decreased by approximately 18 % at 500 μg/mL of stearic acid and stearamide treatment, while trypsin activity decreased by approximately 18 % only by stearic acid treatment (500 μg/mL). Subsequently, fluorescence spectroscopy, circular dichroism spectroscopy, and molecular docking technology were employed to investigate the inhibition mechanism of protease activity by migrating substances in three systems: stearic acid-trypsin, stearic acid-pepsin, and stearamide-pepsin. Results showed that the inhibitory effect of stearic acid on trypsin is a reversible mixed inhibition, whereas the inhibitory effects of stearic acid and stearamide on pepsin are non-competitive. In all three systems, ΔH < 0, ΔS < 0, and ΔG < 0, indicating the binding process between the migrant and the protease is a spontaneous exothermic process primarily driven by hydrogen bonding and van der Waals forces. In addition, their binding constants are all around 104 L/moL, indicating that there are moderate binding affinities exist between migrants and proteases. The binding process results in the quenching of the protease's endogenous fluorescence and induces alterations in the enzyme's secondary structure. Synchronized fluorescence spectroscopy showed that stearic acid enhanced the hydrophobicity near the Tyr residue of trypsin. The molecular docking results indicated that the binding affinity of stearic acid-trypsin, stearic acid-pepsin, and stearamide-pepsin was –22.51 kJ/mol, −12.35 kJ/mol, −19.28 kJ/mol respectively, which consistent with the trend in the enzyme activity results. This study can provide references for the selection of milk packaging materials and the use of processing additives, ensuring food health and safety.

EXPLORING THE IMPACT OF DIFFERENT PACKAGING TYPES AND REPEATED PACKAGE OPENING ON VOLATILE COMPOUND CHANGES IN GROUND ROASTED COFFEE

In this study, the dynamics of volatile compound alterations during the storage of ground roasted coffee in various packaging were investigated using solid-phase microextraction-gas chromatography-mass spectrometry. Each type of packaging underwent repeated opening and closing, simulating the gradual consumption behavior of the consumer who consumes ground coffee in smaller doses over time. The experimental results revealed that after 30 days of storage, 35 to 45% of the volatile substances originally present in the coffee were lost regardless of the type of packaging used. Notably, storing coffee in a paper sachet proved to be the least effective method, resulting in a loss of over 80% of all volatile coffee substances during this storage period.

Complementary nanodomain structures in topologically close-packed precipitates of Al-Zn-Mg-Cu alloy

High-strength aluminium alloys attract continuous research interest, owing to their wide use in aerospace and terrestrial transportation industries. The performance of the alloys is essentially determined by nanoscale precipitates, thus understanding the structure and formation mechanism of the precipitates during thermal processing is of great importance. Here, we reveal complementary domain structures in precipitates in a high-strength Al-Zn-Mg-Cu alloy using a combination of aberration-corrected high-angle annular dark-field scanning transmission electron microscopy and energy dispersive X-ray spectroscopy. Through the transfer of fivefold symmetry polyhedra at domain boundaries, the intermediate precipitates develop two sets of highly ordered and structurally complementary nanoscale domains in their nucleation and growth. This new type of atom packing maintains the topologically close-packed structure inside the precipitates while reducing the lattice misfit with the Al matrix and the barrier of structural transformations on two interfaces, demonstrating good thermal stability. Our discoveries lead to insight into the precipitate evolution in the Al-Zn-Mg-Cu alloy system and can help understand other precipitation processes of complex structured phases. Furthermore, the evolution process demonstrates an advanced mode of building metastable architectures with nanoscale interlocking pieces in alloy matrixes, which may inspire strategies to obtain high-strength, lightweight and thermostable alloys.

A Cross-Country Study of Cigarette Affordability and Single-Stick Purchases Using Survey Data From African Countries.

Reducing cigarette affordability is paramount for reducing cigarette consumption. Measuring affordability requires data on cigarette prices. Unlike the commonly used retail price of a 20-pack of the most-sold cigarette domestically, survey-derived cigarette prices reflect differences arising from the brand variety and the types of packaging in which cigarettes are purchased. This paper uses self-reported cigarette price data from the eight African countries that have implemented the Global Adult Tobacco Survey (GATS) to construct country-level Relative Income Prices. The relationship between cigarette affordability, cigarette smoking prevalence, and cigarette smoking intensity, is examined using logit models for smoking participation (N = 51122) and generalized linear models for conditional cigarette demand (N = 2443). GATS data are also used to produce nationally representative estimates of the prevalence of single-stick cigarette purchases in the sampled countries. The estimated affordability elasticity of cigarette smoking participation is -0.245 (95% CI = -0.411 to -0.078). The estimated affordability elasticity of smoking intensity is -0.155 (95% CI = -0.286 to -0.023). Single-stick cigarette sales dominate all-markets. The proportion of smokers who reported buying cigarettes in the form of single sticks during their most recent cigarette purchase exceeds 90% in Kenya, Tanzania, and Uganda. The results point to the need for governments in the countries sampled to increase excise taxes in a manner that renders cigarettes less affordable over time, and to enact and enforce legislation that prohibits the sale of single cigarettes. These findings highlight that measures to reduce both the demand and supply of cigarettes will be required to reduce their use in the region. This study is the first to examine the prevalence of single-stick cigarette purchases, and the association between cigarette affordability and smoking outcomes, in the African setting, using data from the GATS. Findings provide local evidence for the countries sampled, which represent over half of sub-Saharan Africa's adult population (aged 15 and older), on the importance of implementing excise tax increases that reduce cigarette affordability over time. They also highlight the need to enact and enforce legislation that prohibits the sale of single cigarettes.

Use of UV-C radiation and packaging to maintain the quality of minimally processed kale

Kale, a imortant crop for family farms, gains added value through minimal processing, enhancing freshness and convenience. UV-C irradiation emerges as a promising method for extending kale's shelf life without chemicals, although standardization is complex due to varying food resistances to light penetration.The study in question analyzed the effects of two different irradiation times on minimally processed cabbage, packaged in bowls and Styrofoam with plastic film, observing changes in physical-chemical and sensory parameters, such as loss of mass, color, pH, and visual and olfactory signs of deterioration. Six treatments were tested, varying the exposure time and the type of packaging, as well as a treatment with chlorinated sanitizer, using the Tukey test at 5% significance to determine the most effective in preserving the product. It was found that the packaging in the cumbuca resulted in less mass loss compared to the tray, and the lowest pH values were recorded in the treatment with UV-C light in the cumbuca, which may indicate that they are an option for reducing the stress of the product after processing. None of the color parameters a* and b* or the luminosity index differed from each other, so it is valid to say that the UV-C radiation and chlorine sanitization treatments applied in the experiment were able to preserve the color of the cabbage samples for a period of 8 days. Therefore, the application of UV-C light did not negatively affect the color, pH or loss of mass of the minimally processed cabbage and combined with the correct packaging can be an alternative to conventional sanitization, in addition to maintaining the original aroma of the product.

Investigations on the Diffusion Behavior of Smoke-Associated Aroma Compounds into the Sausage Matrix as Affected by Casing, Caliber, and Packaging.

The aim of the study was to investigate how smoke-associated flavoring substances behave during storage in Frankfurter-type sausages. The diffusion behavior of seven selected aroma substances in the sausage matrix and the influence of the packaging and the casing were examined over a storage period of 28 days. The sausages were cut into uniformly thick layers at defined time intervals and examined by headspace-solid phase microextraction-gas chromatography-mass spectrometry. In general, three different groups could be distinguished: (1) even distribution over the entire product on the first day after smoking; (2) clear concentration gradient from outside to inside on the first day of storage, which leveled out until day 28 of storage; and (3) a clear concentration gradient that remained present throughout the storage period. In addition, only small effects were found in the distribution of flavorings between two types of packaging, selected casing, or different calibers.
