Abstract:
【Objective】 Select the best packaging method to maintain the best shelf-life quality of flat peach after transportation, the effects of different packaging on shelf-life firmness, soluble solid (SSC), decay rate, relative conductivity, polyphenol oxidase (PPO), peroxidase (POD) and vitamin C (VC) were studied.
【Methods】 Using Ingle flat peach as test material, the physical and chemical indexes of flat peach with shelf life of 4 days at room temperature were determined after logistics transportation in different fresh-keeping packages (no packaging, no packaging + storage bag, homemade buffer pad, homemade buffer pad + storage bag, foaming net, foaming net + storage bag).
【Results】 Compared with other packaging home-made cushion + plastic bag, the fresh-keeping effect was the best, followed by homemade buffer pad, which could effectively maintain the higher SSC, hardness, POD and VC contents of the peach, and effectively inhibit the rise of fruit decay rate, relative electrical conductivity and PPO.
【Conclusion】 The effect of plastic bag packaging is better than that of non-plastic bag packaging, the effect of homemade buffer pad and foaming net packaging is better than that of non-packaging group, homemade buffer pad, homemade buffer pad + plastic bag packaging can maintain better quality of fruit shelf life after logistics transportation, reduce the problem of fruit shelf life quality decline caused by mechanical collision during transportation, thus achieving the purpose of long distance transportation of peaches.
