This staggering amount of food waste is a serious problem in the food supply chain. However, the development and use of smart-responsive packaging materials has the potential to reduce food waste and extend shelf life. For example, some novel materials such as composite films with photocatalytic properties have been developed for fruit packaging, which can preserve strawberries for an extended period. However, existing smart packaging materials still face challenges in providing efficient, flexible and timely response. Furthermore, health threats from current packaging systems are a concern. For instance, residual chemicals from processing techniques and the excessive release of active molecules, such as some nanomaterials used in packaging, can threaten human health. Therefore, further development and optimization of smart packaging materials that can timely respond to changes in the storage micro-environment are crucial for food preservation. This article provides an overview of the latest advances in smart responsive packaging that employ multiple stimulus responses, summarizing the response mechanisms and application advances of temperature, humidity, gas, pH, and light smart responsive packaging. In addition, the article consider the challenges to further developing smart responsive packaging systems and suggests possible solutions. Responding to actual production needs, new approaches, such as material safety assessment and improved response sensitivity, can be considered in combination with artificial intelligence techniques to better design applicable smart packaging systems. These developments are important for reducing food waste, improving food shelf life, and ensuring consumer safety.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"112 ","pages":"Article 102597"},"PeriodicalIF":2.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its populations are universally regulated with insecticides, but novel, safer and more efficient methods of control are needed. One such method is the Trojan Female Technique (TFT) which is based on the existence of male harming/female benign mitochondrial haplotypes. The introduction of females carrying haplotypes with male-specific negative effect into the target population can lead to its self-perpetuating suppression over generations. Due to the coevolution of mitochondrial and nuclear genomes, it is possible for nuclear variants that compensate for the negative effects of male harming mitochondrial haplotypes to evolve. Therefore, one of the requirements for the applicability of TFT is that candidate mitochondrial haplotypes confer their negative effects on males in diverse nuclear backgrounds. In this study, we used the previously described mitochondrial haplotype, MG3b, which reduces male-only fertility, and placed it in a range of nuclear backgrounds from three different natural populations. The goal was to test whether its effects on male and female fertility are dependent on interactions with different nuclei. Our results showed that MG3b consistently decreases male fertility independently of the nuclear environments, while having no negative effect on females. Additionally, we found no statistically significant effect of mitonuclear interactions, suggesting that there is no standing variation of compensatory mutations in nuclear backgrounds. These results indicate that the MG3b haplotype could be used in the TFT in different natural seed beetle populations.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"112 ","pages":"Article 102595"},"PeriodicalIF":2.7,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143471201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about the changes of protein conjugated N-glycans in peaches during storage. In this study, a systematic comparison of the N-glycan profiles of three peach cultivars with distinct flesh types, specifically, the soft-melting “Hu Jing”, the hard-melting “Xia Hui 6″, and the stonyhard “Xia Cui” was provided. The study monitored the structure and content changes of these N-glycans during storage. Fourteen different N-glycan structures were identified using Matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry. A consistent N-glycan profile with varying relative content was observed among three cultivars. MMXF³, GnGnXF³, and MM were characterized as representative structures associated with ripening, showing statistically significant correlations with firmness. The conversion of GnGnXF³ to MMXF³ were proposed to be catalyzed by β-Hexs, which exhibited significantly increased activities in all three cultivars during storage. The degradation of high-mannose N-glycans to yield MM structure were observed, but no significant increase in α-Man activities was observed. Real-time qPCR results demonstrated that distinct gene expression patterns of β-Hexs and α-Mans existed among three cultivars. The expressions of genes hex0020 and man4915 were highest and exhibited a climacteric pattern in the “Hu Jing” cultivar. In contrast, these same genes displayed a double-peak expression pattern in the “Xia Hui 6” cultivar and steadily decreased in the “Xia Cui” cultivar. Our findings provide detailed insights into the changes of N-glycome associated with peach ripening and suggest potential target genes for preventing excessive softening in peaches.
