Because of high water loss and rot observed in postharvest sweet potato ( Ipomoea batatas (L.) Lam.) roots, a carnauba wax (CW)–based nanoemulsion without or with glycerol monolaurate (CW-GML) was developed by a high-energy emulsification approach. The effects of the two coatings on decay, respiration rate, weight loss, surface color, total soluble sugar, and starch content as well as the sensory quality of sweet potato roots were investigated during storage at 20°C for 50 days. Compared with the control treatment (water) and CW coating alone, CW-GML coating exhibited higher emulsion stability and antifungal activity, and treatment resulted in a uniform and continuous coating on roots. The CW-GML and CW coatings both effectively reduced root weight loss and respiration rate and inhibited decay incidence compared with control roots during storage. The CW-GML coating showed markedly stronger inhibition of root rot than the CW coating. Both the CW-GML and CW coatings promoted an increase in root sweetness but did not negatively impact perceived flavor. The overall results demonstrate that the CW-GML coating holds great promise as an effective postharvest technology to preserve food quality and extend shelf life of sweet potato roots.

Summary Post-harvest apricot fruits are susceptible to moisture loss and disease leading to quality deterioration. Herein, we identified that the cell wall of the wheat grain regulated the hydration properties of grains. Arabinoxylan/β-glucan/ferulic acid/cellulose (ABF-C) composite films simulating the cell wall of the wheat aleurone layer were prepared and showed excellent thermodynamic properties and hydration properties. Meanwhile, the decay percentage, weight loss percentage and respiration intensity of apricot fruits at 35 days of storage were greatly decreased by 23.5%, 23.93% and 39.95%, respectively, and the shelf life of apricot fruits was extended by 7 days after the coating ABF-8%C composite film treatment. The ABF-C composite films effectively prevented the dissipation of moisture of high mobility in apricot fruits during storage. We provide new insight into moisture regulation mechanism of edible films simulating cell wall structure on post-harvest fruits.

Logistics transportation is the critical procedure that sprouts must go through from producers to consumers, but during this transportation, it is very easy to cause quality deterioration. Generally, the quality of fresh peanut sprouts during cold chain transportation is maintained by using the high polymer phase change cold storage agent (CSA). In this research, different quantities of CSA were used to maintain peanut sprouts quality，and the effects of CSA on sprouts quality under simulated transportation conditions were investigated for 5 days, including overall quality, water content, ascorbic acid content, total phenolic and total flavonoid contents, malondialdehyde (MDA) content, weight loss rate, along with the activities of superoxide dismutase (SOD) and catalase (CAT). According to the overall quality, it is meaningful to observe the changes of each index within 3 days. Results indicated that 4 bags of CSA could decrease the temperature to 8.4 °C within 580 min and keep rising slowly until the maximum temperature reached 18.9 °C at 4260 min. In addition, it effectively prevented the loss of water (93.87%) and ascorbic acid (5.38 mg/100 g), as well as inhibited the production of MDA, which was attributed to a slow metabolism in low temperatures. Moreover, the 4 bags of CSA had no negative effects on the contents of total phenolic and flavonoid along with CAT activity of peanut sprouts, and the sensory quality was maintained at an optimum level. In conclusion, it had a positive effect on the maintenance of quality during transportation when the mass ratio of sprouts to CSA was 15:8 and the volume ratio of styrofoam container and CSA was 10:1.

This study examines the effects of edible chitosan coatings reinforced with tannic acid (TA) and ferric iron (Fe 3+ ) double crosslinking on the quality of wax apples stored at room temperature. The effects of chitosan (CS) and CS/TA/Fe coatings on wax apple weight loss, decay index, respiration rate, titratable acidity, total phenolics, and other quality parameters were investigated. The weight loss and decay index of wax apples increased over time, with the CS coating delaying both compared to untreated fruits. On the final storage day, the CS/TA/Fe coating reduced weight loss by 34.35 % and maintained SSC at 9.17 ± 0.49. Additionally, the activities of catalase (CAT), ascorbate peroxidase (APX), polygalacturonase (PG), and pectin methyl esterase (PME) were evaluated. Compared to other groups, the CS/TA/Fe coating more effectively preserved the CAT and APX activities while delaying the increase in PG and PME activities. CS/TA/Fe coating preserved wax apple cell wall integrity and reduced respiration and oxidative damage (malondialdehyde levels), likely via a CS/TA/Fe supramolecular network limiting gas exchange, thus extending shelf life and maintaining quality.

The development of degradable plastic has emerged as a critical strategy to address plastic pollution. This study focuses on polybutylene adipate terephthalate (PBAT) as the subject of investigation, systematically exploring its degradation behavior and microbial mechanisms in soil environments. Microorganisms such as Escherichia coli ( E. coli ), Staphylococcus aureus ( S. aureus ), and Bacillus flexus ( B. flexus ) were introduced, and the degradation efficiency and mechanisms of PBAT were analyzed under varying conditions of temperature (45, 55, and 65 ℃), ventilation (100 and 200 mL/min), and burial depth. The experimental results revealed that E. coli , under 100 mL/min ventilation at 55 ℃, exhibited the highest degradation efficiency, with a weight loss rate of 16.45% in 30 days, significantly outperforming the other strains ( S. aureus : 12.49%; B. flexus : 3.54%). It was found that the presence of surface cracks and ester bond (C=O, 1710 cm⁻¹) rupture by SEM and FTIR analysis, and degradation occurs preferentially in the amorphous zone and that crystallinity increases throughout the degradation process by XRD and DSC results. This study elucidates PBAT degradation was catalyzed by microorganisms through the secretion of key enzymes providing a novel foundation for optimizing the environmental application of degradable plastic and advancing green technology development.

Botrytis cinerea (B. cinerea) and Colletotrichum gloeosporioides (C. gloeosporioides) were isolated from the decaying strawberry tissue. The antifungal properties of Monarda didyma essential oil (MEO) and its nanoemulsion were confirmed, demonstrating complete inhibition of the pathogens at concentrations of 0.45 μL/mL (0.37 mg/mL) and 10 μL/mL, respectively. Thymol, a primary component of MEO, was determined as an antimicrobial agent with IC50 values of 34.51 (B. cinerea) and 53.40 (C. gloeosporioides) μg/mL. Hippophae rhamnoides oil (HEO) was confirmed as a potent antioxidant, leading to the development of a thymol-HEO-chitosan film designed to act as an antistaling agent. The disease index and weight loss rate can be reduced by 90 and 60%, respectively, with nutrients also being well-preserved, offering an innovative approach to preservative development. Studies on the antifungal mechanism revealed that thymol could bind to FKS1 to disrupt the cell wall, causing the collapse of mitochondrial membrane potential and a burst of reactive oxygen species.

Considering that the peptide from Idesia polycarpa Maxim.cake meal polypeptide (CIP) is a novel antioxidant agent, this study aimed to develop an efficient and safe food film by incorporating the CIP agent into a gelatin matrix. The films with different concentrations of CIP were characterised and applied in the preservation of nectarines. The results indicated that the CIPF/3% fraction exhibited significant moisture barrier properties, with a water vapor permeability (WVP) of only 8.12 % ± 0.09 %. Additionally, it demonstrated excellent mechanical and antioxidant properties, with scavenging capacities of 76.31 % ± 0.597 %, 65.98 % ± 0.444 %, and 60.98 % ± 0.231% for DPPH, ABTS, and hydroxyl radicals, respectively, surpassing those of other fractions. In nectarine freshness preservation, the Coating/3% fraction showed the best performance. It significantly reduced the weight loss rate of nectarines, improved fruit firmness, maintained the pH value, and minimized nutrient losses, including ascorbic acid and Total soluble sugars (TSS). Furthermore, it effectively preserved the bright surface color of nectarines and extended their shelf life. In summary, the specific environmental protection, safety, and preservation qualities of the CIPF/Coating in food packaging suggest a promising potential for its application.

The production and use of ozone micro-nano bubble water (O 3 -MNBW) is an innovative technology that prolongs the reactivity of aqueous-phase ozone and maintains the freshness and quality of fruits and vegetables by removing pesticides, mycotoxins, and other contaminants. The quality of parsley treated with different concentrations of O 3 -MNBW was investigated during storage at 20 ℃ for 5 d, and found that a ten-minute exposure of parsley to 2.5 mg·L −1 O 3 -MNBW effectively preserved the sensory quality of parsley, and resulted in lower weight loss, respiration rate, ethylene production, MDA levels, and a higher level of firmness, vitamin C, and chlorophyll content, relative to untreated parsley. The O 3 -MNBW treatment also increased the level of total phenolics and flavonoids, enhanced peroxidase and ascorbate peroxidase activity, and inhibited polyphenol oxidase activity in stored parsley. Five volatile signatures identified using an electronic nose (W1W, sulfur-compounds; W2S, ethanol; W2W, aromatic- and organic- sulfur compounds; W5S, oxynitride; W1S, methane) exhibited a significant decrease in response to the O 3 -MNBW treatment. A total of 24 major volatiles were identified. A metabolomic analysis identified 365 differentially abundant metabolites (DMs). Among them, 30 and 19 DMs were associated with characteristic volatile flavor substance metabolism in O 3 -MNBW and control groups, respectively. The O 3 -MNBW treatment increased the abundance of most DMs related to flavor metabolism and reduced the level of naringin and apigenin. Our results provide insight into the mechanisms that are regulated in response to the exposure of parsley to O 3 -MNBW, and confirmed the potential use of O 3 -MNBW as a preservation technology.
