Co-Application of 1-MCP and Laser Microporous Plastic Bag Packaging Maintains Postharvest Quality and Extends the Shelf-Life of Honey Peach Fruit

Abstract

Honey peach (Prunus persica L.) is highly nutritious; it is an excellent source of sugars, proteins, amino acids, vitamins, and mineral elements. However, it is a perishable climacteric fruit that is difficult to preserve. In this study, “Feicheng” honey peach fruit was used as a test material to investigate the synergistic preservation effect of 1-methylcyclopropene (1-MCP) and laser microporous film (LMF). The peach fruits were fumigated for 24 h with 2 μL L−1 1-MCP, then packed in LMF. In comparison with the control treatment, 1-MCP + LMF treatment markedly decreased the respiration rate, weight loss, and rot rate of peach fruits. Moreover, the combination of 1-MCP and LMF suppressed the increase in soluble solids (SS) and reducing sugars (RS), as well as the decrease in titratable acid (TA) and ascorbic acid (AsA). The combined application also maintained a high protopectin content and low soluble pectin content; it reduced the accumulation of superoxide anions (O2−) and hydrogen peroxide (H2O2). Except in a few samples, the catalase (CAT) and ascorbate peroxidase (APX) activities were higher when treated by 1-MCP + LMF. Conversely, the phenylalanine deaminase (PAL), peroxidase (POD), lipase, lipoxygenase (LOX), polygalacturonase (PG), β-glucosidase, and cellulase (Cx) activities were lower than in the control. Furthermore, 1-MCP + LMF treatment reduced the relative abundances of dominant pathogenic fungi (e.g., Streptomyces, Stachybotrys, and Issa sp.). The combined treatment improved the relative abundances of antagonistic fungi (e.g., Aureobasidium and Holtermanniella). The results indicated that the co-application of 1-MCP and LMF markedly reduced weight loss and spoilage, delayed the decline of nutritional quality, and inhibited the physiological and biochemical metabolic activities of peach during storage. These changes extended its shelf-life to 28 days at 5 °C. The results provide a reference for the commercial application of this technology.

1‐MCP combined with laser microporous film packaging maintains the quality and prolongs the storage period of Xiahei grapes

“…Li et al . (2022) demonstrated that laser microporous plastic bag packaging for honey peaches effectively controlled the weight loss rate, maintaining it at approximately 10% by the end of storage. Liguori et al .…”

“…Li et al . (2022) reported a similar result regarding the improvement of shelf life and postharvest quality of peach fruit through the co‐application of 1‐MCP and laser microporous plastic bags.…”

“…Laser microporous film (LMF) packaging is a new type of spontaneous modified atmosphere technology that uses laser perforation technology to accurately punch small circular holes of different apertures and quantities on a plastic film, thereby controlling the exchange of gas inside and outside the film. Various LMF parameters have been established for horticultural products with different respiratory processes and widely used in fruit and vegetable storage (Li et al ., 2022). Compared to conventional plastic films, LMF has a wider range of permeability coefficient β values for CO 2 and O 2 ( β = Pco 2 /Po 2 ), which allows for adjustment of permeability rates by altering the size and number of pores.…”

“…It achieves receptor passivation by competitively inhibiting ethylene production and release, thereby impeding the progression of the physiological and biochemical activities associated with senescence (Satekge & Magwaza, 2022). It is particularly effective in delaying and reducing respiratory peaks in climacteric fruit such as apricots (Liang et al ., 2023), plums (Salazar et al ., 2022), and peaches (Li et al ., 2022). Following harvest, grape berries exhibit a non‐respiratory climacteric type, with no discernible respiratory peak during storage.…”

Recent advances in quality preservation of postharvest golden needle mushroom (Flammulina velutiper)

“…1-MCP treatment 1-MCP is a highly effective ethylene inhibitor that competes irreversibly with ethylene for receptor binding sites and inhibits the role of ethylene in promoting ripening and senescence in fruits and vegetables. 27,[92][93][94] As a respiratory leap type of edible mushroom, the postharvest physiological metabolism of the golden mushroom is vigorous, and the rate of quality deterioration is closely related to the amount of ethylene released (Fig. 2 and Table 2).…”
