Abstract

Abstract: The purpose of this paper is to find biological preservation of peach which is safe and effective.This study investigated the effects of SAA and Vc plastic wrap packaging on preservation quality of baihua peaches during normal temperature(28±1)℃. The results showed that 1% SAA achieved lower respiration intensity,conductivity,hardness and TSS than other treatments,thus chose it for the synthesize treatments.It reduced the decay index by 68.1% and MDA content by 12.4% compared with the CK. In synthesize part during preservation,1%SAA and Vc plastic wrap packing effectively reduced the decrease of TSS and being brown,which was significantly better than CK(P<0.05),by delaying substance decomposes.The tests under normal temperature of the 7th day,the SAAPVc sets could remarkably reduce the weight loss rate to 1.5% while the CK group nearly reached 2.8%. In summary,under normal temperature conditions,the combination of 1% SAA and Vc plastic wrap packing could effectively improve the storage quality of juicy peaches.

Key words: Juicy peach, Vc plastic wrap packaging, SAA, Synthesize preservation, Bio-safety
