In this method, Selected Ion Flow Tube–Mass Spectrometer was used to identify and quantify chemical compounds in raw and cooked chicken noodle soup and those that migrated towards the polymer coating of the metal cans. Scanning electron microscopy (SEM) was used to detect the appearance of breaches in the coating of the tested cans, and energy dispersive X-ray spectroscopy (EDS) allowed for analysis of the elemental composition of the internal walls of the tested cans. Inductively coupled plasma–mass spectrometry (ICP-MS) provided information about the migration of iron and tin from the internal walls of the cans into the packaged soups. SEM images showed that breaches developed in the coating of the tested cans when corrosion occurred. The EDS analyses showed that tin and iron exposures were associated with extra peaks in the EDS. These peaks were attributed to sulphur. From the results obtained, it was concluded that the process of heat retorting contributed to the formation of sulphur-containing volatile compounds that bonded to the coating in the headspace of the tested cans. These then penetrated the protective coating and facilitated avenues for other oxidative chemicals in the product to cause corrosion and staining. Results from the ICP-MS analyses showed that tin and iron subsequently migrated from the corroded cans toward the chicken soup. These results thus showed how corrosive compounds in a retorted food initiated corrosion in metal cans.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"2 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138826463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bhat, Rana Muhammad Aadil","doi":"10.1002/pts.2787","DOIUrl":"https://doi.org/10.1002/pts.2787","url":null,"abstract":"Packaging serves as a pivotal component in addressing food losses by extending the shelf life and preserving the quality of both raw and processed food products. Nevertheless, conventional plastic packaging has substantial environmental drawbacks due to its non-biodegradable nature and the inclusion of potentially harmful chemical components. As a result, there is a global shift toward biodegradable packaging obtained from natural sources as a more environmentally friendly and sustainable alternative. In this regard, biodegradable coatings made up of natural sources are very efficient for food packaging purposes because of various significant properties. Moreover, huge amounts of food waste are produced globally, leading to environmental pollution. Utilization of this waste is crucial, with one significant application being the extraction of essential oils (EOs). These oils are incorporated into different coatings materials to enhance their functional properties for better preservation of food products. So, this review covers the potential of EOs derived from food waste materials as bioactive compounds incorporated in biodegradable coatings for enhancing the storage quality and shelf life of food products. The biodegradable coatings enriched with these EOs thereby reduce microbial spoilage, stop moisture loss and act as a barrier against gases that ultimately enhance the product's shelf life. These coatings with EOs also reduce weight loss and stabilize other parameters such as pH, colour, acidity and firmness of food commodities. Different packaging systems using waste-derived EOs have been developed to preserve both plant and animal-origin foods such as fruits, meat, fish, shrimp, mushrooms and cheese. Developing biodegradable packaging from natural polymers along with the incorporation of EOs from food waste is an innovative way of food preservation and waste management.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"32 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138686166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dispersion-coated samples were compared against polyethylene terephthalate (PET) extrusion-coated paperboard, the principal industrial material used for food trays. Results show that, within the investigated properties, waterborne dispersions can achieve similar barrier properties compared with PET, yet at lower dry coat grammage (12 g/m2 vs. 40 g/m2 of PET-coated paperboard). Additionally, the investigated coatings heat-sealed at temperatures as low as 80–90°C, almost 100°C less than PET; however, lower seal forces could be achieved (15–20 N/(25 mm) vs. 23 N/(25 mm) of PET-coated paperboard). Paperboard delamination occurred at the highest seal forces. Dispersion-coated trays were obtained at 4.5–5.0% blank moisture content. Formed trays at industrial processing parameters showed critical coating damage during converting due to tensile stresses. This work shows that milder processing conditions allow a reduction in coat defects.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"268 1 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138546368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on an established library of relative response factors for more than 30 different polymer additives, analytical evaluation thresholds for large volume injectables were determined, and 30 extractables were screened and (semi-)quantitatively analyzed. To identify variations in extractables between batches, multivariate statistical methods such as principal component analysis, heat map analysis, and hierarchical cluster analysis were employed. Additionally, a comprehensive risk assessment of extractables and a biosafety assessment of leachables were conducted. The results of the study revealed that the concentrations of two extractables exceeded the established safety threshold. Moreover, one of these extractables was deemed to pose a mutagenic risk based on the consistent findings of two (Q)SAR software tools. Notably, certain extractables exhibited discrepancies in their content between batches, with particular emphasis on 1,3-bis(3,5-di-tert-butyl-4-hydroxybenzyl)-1,3,5-triazinane-2,4,6-trione. This discrepancy led to inconsistencies in risk levels across batches. However, the levels of leachables detected in the non-PVC soft bags were found to be within the safety threshold, and cytotoxicity assessments consistently yielded negative results for leachables. Consequently, this study provides valuable data for conducting batch stability investigations concerning extractables in large volume parenteral drug delivery containers and other forms of pharmaceutical packaging.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"16 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138546171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of different concentrations of LPHB on the performance of composite films were investigated to determine the optimal amount of addition, and then to prepare both antibacterial and antioxidant films. The antimicrobial properties of LPHB were analysed. The antibacterial, antioxidant, mechanical, barrier properties and morphology of the films were characterized and analysed. The results showed that the addition of LPHB significantly improved the antibacterial and anti-mould properties, oxidation resistance, and barrier properties of the composite film compared to the LDPE film. The best overall performance of the composite film was achieved when the content of LPHB was 1.5%, the antibacterial rate against Escherichia coli and Staphylococcus aureus reached 99%, and the free radical scavenging rate reached 67.22%. In addition, the cling film added with LPHB has better antioxidant and antibacterial properties, which has obvious effect on bread preservation and has potential for application in food packaging.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"14 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138530641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, artificial neural networks are used to predict the crush resistance of corrugated packaging. Among the analysed packages were boxes with ventilation openings, packages with perforations and typical flap boxes, which make the proposed estimation method very universal. Typical shallow feedforward networks were used, which are perfect for regression problems, mainly when the set of input and output parameters is small, so no complicated architecture or advanced learning techniques are required. The input parameters of the neural networks are selected so as to take into account not only the material used for the production of the packaging but also the dimensions of the box and the impact of ventilation holes and perforations on the load capacity of individual walls of the packaging. In order to maximize the effectiveness of neural network training process, the group of input parameters was changed so as to eliminate those to which the sensitivity of the model was the lowest. This allowed the selection of the optimal configuration of training pairs for which the estimation error was on the acceptable level. Finally, models of neural networks were selected, for which the training and testing error did not exceed 10%. The demonstrated effectiveness allows us to conclude that the proposed set of universal input parameters is suitable for efficient training of a single neural network model capable of predicting the compressive strength of various types of corrugated packaging.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"116 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135137783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, paper is prone to water absorption and moisture damage, and it has poor insulation properties, which can impact food quality and user experience. Recently, biopolymers have gained wide interest as the main substrate for paper coatings, providing various qualities for paper‐based materials to meet food packaging requirements. The coating based on chitosan/gelatin/microbeads composite aerogel prepared in this study not only possesses inherent antimicrobial and preservation properties but also enhances the cardboard's mechanical strength, hydrophobicity, and thermal insulation effect after coating on cardboard. When the coating thickness was 30 μm, the tensile strength of the cardboard was enhanced by 0.65 kN/m, the contact angle increased by 19.3°, and the thermal conductivity coefficient decreased by 0.024 W·m −1 ·K −1 . Therefore, the biopolymer composite coating developed in this study provides an eco‐friendly substitute for plastic coatings on cardboard. In addition to bacteriostatic and preserving freshness, it can also address paper‐based material shortcomings, ensuring food quality and safety with comprehensive packaging protection.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"2 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135391552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various experimental studies were designed to explore factors affecting the conversion of the COR to equivalent free fall drop height. These factors include the number of drops, drop height, drop orientation, drop base, temperature and humidity on the COR. The results indicate that the number of drops and drop orientation are the two most influential factors affecting COR values. As the package undergoes more drops, the COR increases. Among the various orientations, the COR is largest for flat drops, followed by edge and corner orientations. Within flat drops, a smaller impact area results in a smaller COR. Manufacturing joints and the flats, edges and corners adjacent to manufacturing joints tend to yield smaller COR values. A COR correction matrix was developed to correct the conventional COR calculation. This matrix allows engineers to refine COR values based on the number of drops and drop orientations in the field. The matrix‐corrected equivalent free fall drop heights demonstrated an average accuracy of 96%. Compared to the conventional COR calculation method, it effectively reduces errors by a factor of 2–3.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"137 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135372086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the transport of live small animals, such as day‐old chickens, the animals may only stay in the boxes for a very limited period, in this case, 48 h. Therefore, it is important to be able to model the strength behaviour of these boxes concerning packaging material requirements and sustainability. The aim of this study was to determine the short‐ and relatively long‐term strength of day‐old chicken packages to better estimate packaging design and to use these data to establish an analytical creep model with suitable parameters that adequately approximate the measured data. Two types of packages were tested, and two types of creep models were used to model the creep strain‐time graphs. The creep behaviour of the two samples was tested at four different uniaxial load cases, with consistent environmental conditions during the tests (23°C and 50% relative humidity [RH]). At the two highest loads, both samples failed before the 48‐h cycle, indicating a significant difference in box strength between short‐term and long‐term load tests. The secondary creep strain rate increases with the magnitude of the compressive load. When comparing the two creep models for both box types, the Power law provided the best accuracy at the 50% of box compression test (BCT) load case, while at the other three load cases, the Andrade law showed better predictions.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136157202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
