Abstract The interest in natural antioxidants for the development of active food packaging is increasing, since lipid oxidation has a negative impact on food quality and people's living standards are changing. The aim of this work was to obtain Malpighia emarginata DC pomace extract (MEPE), as well as to develop poly(lactic acid) (PLA)‐based films with antioxidant activity, through the incorporation of MEPE. MEPE showed antioxidant activity through the DPPH and ABTS assays, 127.16 ± 9.70 μmol TEAC g −1 extract and 322.84 ± 19.38 μmol TEAC g −1 extract, respectively. The HPLC quantification revealed that quercetin and isorhamnetin were found at concentrations of 244.77 ± 8.42 and 707.20 ± 23.17 μg g −1 , respectively. The properties of the films were influenced by the presence of MEPE, which caused a plasticizing effect on the PLA film, reducing the tensile strength and Young's modulus and increasing the elongation at break and water vapour permeability. The antioxidant property test (DPPH and ABTS) of the films was shown to be improved with the addition of MEPE. Despite changes in the film properties, they have potential for application as active food packaging. This work showed the potential utilization of agriculture pomace to produce antioxidant additive and its application as antioxidant in active food packaging, since they showed excellent antioxidant activity in radical scavenging activity tests.
摘要由于脂质氧化对食品质量的负面影响以及人们生活水平的不断变化，人们对开发天然抗氧化剂用于活性食品包装的兴趣越来越大。本研究的目的是获得马皮蝇DC渣提取物(MEPE)，并通过加入MEPE制备具有抗氧化活性的聚乳酸(PLA)基薄膜。通过DPPH和ABTS测定，MEPE提取物的抗氧化活性分别为127.16±9.70 μmol TEAC g - 1和322.84±19.38 μmol TEAC g - 1。HPLC测定结果显示槲皮素和异鼠李素的浓度分别为244.77±8.42和707.20±23.17 μg−1。MEPE的存在影响了薄膜的性能，对PLA薄膜产生了塑化作用，降低了拉伸强度和杨氏模量，增加了断裂伸长率和透气性。MEPE的加入提高了膜的抗氧化性能(DPPH和ABTS)。尽管薄膜性能发生了变化，但它们具有作为活性食品包装的应用潜力。研究表明，农业渣渣具有良好的抗氧化活性，可用于生产抗氧化添加剂，并可作为活性食品包装中的抗氧化剂。

Abstract The food packaging sector is focused on developing innovative materials to enhance food safety and quality while reducing environmental impact. Accordingly, this study aimed to develop packaging based on bovine gelatin (G) blended with crude sweet orange juice pomace pectin (SOPP) at different ratios (G/SOPP = 85/15, 65/35, 50/50, w/w). The obtained crude SOPP was highly methylated and exhibited antioxidant and antibacterial properties due to the presence of galacturonic acid (<70%) and phenolic compounds (58.2 ± 0.8 mg/g SOPP). High‐performance liquid chromatography with diode array detection analysis revealed the presence of hesperidin, catechin, and naringin as major phenolic compounds in SOPP. Further, the incorporation of this latter improved gelatin‐based packaging structural homogeneity, opacity, water vapour barrier features, glass transition temperature and tensile strength. G‐SOPP (50/50) film showed efficient antibacterial activity against Escherichia coli and Bacillus subtilis and high antioxidant potential reaching values of 0.7, 48.7%, 76.7% and 68.9% for reducing power, β‐carotene bleaching inhibition, DPPH (2,2‐diphenyl‐1‐picrylhydrazyl) and ABTS + (2,2′‐azinobis‐[3‐ethylbenzothiazoline‐6‐sulphonic acid]) radicals scavenging activities, respectively. Another interesting finding is that the combination of G and SOPP reduced the oil solubility of G‐SOPP films suggesting great physical integrity of the film over 63 days. The polyphenol content released from G‐SOPP blend film in a fatty simulant increased as SOPP content of films was increased. G‐SOPP (50/50) film, designed as a pouch, delays the photooxidation process of virgin olive oil over 63 days of storage time, without altering its organoleptic properties. Overall, these outstanding results highlighted the potential use of gelatin–pectin blend films for active packaging of oils and lipid‐based foods.

Abstract Hydroxypropyl methylcellulose (HPM) is a viscous modified natural polymer that is utilised as thickener, emulsifier and reducer of serum cholesterol. Novel films composed from HPM and corn silk polysaccharides (CSP) were prepared (HPM‐corn silk [CS]). The impact of using different percentages of CSP on the characteristics of HPM‐CS was studied. Results showed that replacing 37.5% of HPM with CSP led to a significant improvement in mechanical properties, with an increase of 58.71% for tensile strength and 54.29% for elongation at break. In addition, the produced films showed improved opacity, antioxidant activities and a smooth, continuous surface without any grooves, as well as being biodegradable. However, the thermal stability was reduced, and the crystallinity shapes were disrupted at higher concentrations due to the inclusion of CSP in the HPM‐CS films. The best HPM concentration (1 g/100 mL) with optimum CSP concentration of (0.6 g/100 mL) was used as food packaging material for low‐moisture mozzarella cheese. The packaging material kept the stability of total microbial count in hygienic scale up to 40 days of cold storage, moisture loss and pH values up to 30 days. Additionally, the results of hedonic sensory evaluation were satisfied compared with fresh cheese until 30 days of storage.

A continuum damage framework is proposed for modelling the delamination process occurring in paperboard during mechanical loading. The main application of interest is line creasing and subsequent line folding used in package forming. To adequately capture creasing and folding, a continuum damage framework that uses a single isotropic damage variable that evolves with the plastic strains associated with out‐of‐plane shearing is used. The damage evolution is calibrated against folding experiments for a specific reference mesh, and a simple scaling strategy is proposed to reduce the inherent mesh dependency. To highlight the potential of the proposed model, an illustrative 3D example is considered where a paperboard sheet is creased by two plates and folded to resemble the corner of a package.

Growing awareness of fossil depletion, plastic pollution, and food spoilage has led to the exploration of bioresources as alternatives for producing packaging films for highly perishable food. In this study, we utilized a novel integrated process using natural‐based solvents to isolate cellulose, hemicellulose, and lignin from cattail leaves, an abundant invasive plant. The process yielded cellulose, hemicellulose, and lignin with recovery yields of 96.2 ± 1.2%, 92.5 ± 1.6%, and 94.3 ± 0.7% and purities of 96.3 ± 0.6%, 97.7 ± 0.9%, and 98.9 ± 0.5%, respectively. Spherical nanoparticles (60–90 nm) were synthesized through ultrasonication and their structural purity were confirmed by FTIR, XRD, and XPS analyses. These nanoparticles were incorporated as reinforcement into chitosan (C) films. Cellulose nanoparticles (CNP) and lignin nanoparticles (LNP) significantly enhanced film tensile strength (up to 27% at 1.5% loading), while hemicellulose nanoparticles (HNP) increased film elongation (up to 42%). The complex structures of HNP and LNP promoted higher free radical formation, resulting in enhanced antioxidant activity of up to 80% and 82%, respectively. LNP‐reinforced films exhibited superior antimicrobial properties due to their polyphenolic structure. Preservation tests were conducted by packaging poultry meat in the films and refrigerating it for 30 days. Poultry meat packed in LNP‐reinforced film maintained its quality within permissible limits throughout the entire 30 day period, while LDPE, plain chitosan, C‐CNP, and C‐HNP films reached consumable limits on the 5th, 10th, 15th, and 25th days, respectively. This study highlights the production of sustainable nanoparticles from invasive crops and their application in the development of active packaging films for fresh poultry meat.

This study investigated the effects of fructooligosaccharide (FOS) and inulin (IN) on the properties of sodium caseinate‐based films containing Lactobacillus rhamnosus GG. The optimal formulations were determined and tested for coating sliced cheese during storage. FOS and IN generally increased the thickness and moisture values of the films, while opacity increased with the increase in IN concentration. Tensile strength decreased with FOS and IN, and elongation at break decreased at high prebiotic concentrations. The viability of L. rhamnosus after the drying of the film solution was between 77.67% and 89.91%, and total prebiotic concentration above 2% generally decreased drying stability of L. rhamnosus. The optimal formulations were 0% FOS + 0% IN, 1% FOS + 0% IN and 0% FOS + 1% IN, respectively. These film matrices were found to be suitable carriers for L. rhamnosus. Coating treatments reduced moisture loss, acidity and hardness increase in cheese slices, but decreased luminosity. The probiotic counts in coated cheese were sufficient for therapeutic effect after approximately 20 days.

Herein, we investigate the information older adults use when selecting over‐the‐counter (OTC) medications. Two specific objectives framed our work: (1) determine what information older adults believe to be important when selecting an OTC and (2) determine what information they believe to be important when assessing an OTC product's appropriateness for use. Five focus groups comprised of OTC users aged 65+ (total n = 24) were led using a moderator guide which incorporated surveys, individual activities and guide group discussions in support of these objectives. Complete transcripts of group discussions were coded into emergent themes and analysed in conjunction with survey results. Four broad themes were identified: price, search for advice, perception of efficacy and perception of safety. While we framed our study specific to labelling information, expecting older consumers to use a deliberative decision‐making process, typical of products that carry risk, what emerged was the fact that they utilized a habit‐based process that was largely driven by price comparisons and previous success with products. The specific, intensive information from the Drug Facts Label (DFL) required by the US Food and Drug Administration (FDA), which we had designed our questions around, was not the information discussed intently by our participants. Data suggests that they rely on simple heuristics available through other aspects of the packaging.

Brazil nuts are largely consumed either as a whole or as an ingredient in different food products. These seeds are rich in lipids that are susceptible to oxidation, which is the most common cause of deterioration in their sensory and nutritional quality. Active food packagings are a potential strategy to prevent food lipid oxidation. In this work, thermoplastic starch/poly (butylene adipate–co–terephthalate) (TPS/PBAT) containing water‐soluble curcumin and pinhão (Araucaria angustifolia) extract as natural antioxidants were used to package Brazil nuts (Bertholletia excelsa). Packaged nuts were stored under different temperatures and analysed for up to 30 days of storage. The lipid profile of the oil extracted from the nuts before packaging showed that it is rich in unsaturated fatty acids. The UV–Vis spectra were organized into an augmented matrix and then into a principal component analysis (PCA). Results showed that for 10°C, the control TPS/PBAT film and the film containing pinhão extract resulted in the best preservation. When evaluated at 25°C, the nuts packed in films that contained water‐soluble curcumin presented the best oxidative stability until the 15th day of storage. After this period, the oxidation reactions were significant for all samples, indicating a possible compromise on the sensory and nutritional quality of Brazil nuts.

Innovation literature shows that the characteristics of a company's innovation processes determine their performance in different areas. In this study, we adopt a general conceptual model from innovation theory and apply it to packaging innovation. This helps identify and describe subprocesses in packaging innovation and how to measure their performance. It also links the packaging innovation process to the cost and climate performance of packaging. Based on the modified model for packaging innovation, the purpose of this paper is to develop and apply a scorecard for assessing the packaging innovation process.

Based on the modified model for packaging innovation, the purpose of this paper is to develop and apply a scorecard for assessing the packaging innovation process.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"8 7","pages":"969 - 981"},"PeriodicalIF":2.6,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72373044","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}
Ethylene scavenging‐active packaging is getting more interest to reduce postharvest losses of ethylene‐sensitive produce to overcome the limitations of traditional postharvest technologies. The aim of this study is to monitor behaviour of ethylene‐sensitive products to different ethylene scavenging systems combined with modified atmosphere packaging (MAP). Banana (Musa paradisicum L. var. Anamur) and kiwi (Actinidia deliciosa L. var. Hayward) were packaged with low‐density polyethylene (LDPE) bags containing ethylene scavenging sachet and ethylene scavenging‐active LDPE bags. Only passive MAP was used for bananas stored at 13°C for 12 d. Both passive and active MAP (5% O2, 5% CO2) were used for kiwi stored at 4°C for 30 d. LDPE bags with no ethylene absorber and unpackaged produces were the control groups. O2, CO2 and ethylene concentrations, mass loss, texture, colour, TSS %, titratable acidity and sensory analysis were performed during storage. O2% in the control LDPE bags decreased below 2% on 6th d, while LDPE bags containing sachet and active LDPE bags remained above critical O2 level for bananas during the entire storage. The lowest ethylene concentration was 0.45 μl L−1 in both active systems on 12th d. Equilibrium atmosphere was maintained in active and passive MAP after 5th d for kiwifruit. The lowest ethylene concentrations were determined as 0.47 μl L−1 and 0.50 μl L−1 in the sachet included LDPE and active LDPE, respectively under passive MAP at the end of the storage. In conclusion, bananas packaged with both active systems were acceptable for 9 d considering physicochemical and sensory properties. The kiwifruit was acceptable for 30 d using both ethylene absorbing systems under passive MAP.
乙烯清除活性包装在减少乙烯敏感产品采后损失方面越来越受到关注，以克服传统采后技术的局限性。本研究的目的是监测乙烯敏感产品对不同的乙烯清除系统与改性气氛包装(MAP)相结合的行为。香蕉(Musa paradisicum L. var. Anamur)和猕猴桃(Actinidia deliciosa L. var. Hayward)分别用低密度聚乙烯(LDPE)袋和具有清除乙烯活性的LDPE袋包装。在13°C下储存12 d的香蕉只使用被动MAP。在4°C下储存30 d的猕猴桃使用被动和主动MAP (5% O2, 5% CO2)。没有乙烯吸收剂的LDPE袋和未包装的产品为对照组。在储存期间进行O2、CO2和乙烯浓度、质量损失、质地、颜色、TSS %、可滴定酸度和感官分析。对照LDPE袋的O2含量在第6 d降至2%以下，而含小袋LDPE袋和活性LDPE袋在整个贮藏过程中均保持在临界O2水平以上。第12 d，两种活性体系的乙烯浓度最低，均为0.45 μl L−1。第5 d后，猕猴桃的主、被动MAP维持了平衡气氛。贮藏末期，在被动MAP下，LDPE和活性LDPE的乙烯浓度最低，分别为0.47 μl L−1和0.50 μl L−1。综上所述，考虑到理化和感官特性，用这两种活性体系包装的香蕉在9天内是可以接受的。在被动MAP条件下，两种乙烯吸收体系对猕猴桃的处理时间均为30 d。
