Orthogonal Array Design for Optimization of Phenyllactic acid-Sodium alginate Blend Coating and Its Effect on the Browning and Quality of Minimally Processed Lily Bulbs.

BACKGROUND: In order to develop active packaging of lily products, we for the first time investigated the effects of phenyllatic acid (PLA) incorporated into a sodium alginate (SA)-based coating on the quality of minimally processed lily bulbs stored at 4 °C for 15d.

RESULTS: L9 (34 ) orthogonal array design was showed that the optimal concentrations of PLA, SA and glycerinum were 0.03 mol L-1 , 0.03mol L-1 and 0.05 mol L-1 to prepare blend coating. It was noticed that PLA/SA blend coating treatment could inhibit browning and maintain the firmness and ascorbic acid of minimally processed lily bulbs. Compared with the control, polyphenol oxidase (PPO), peroxidase (POD) and phenylalnine ammonialyase (PAL) activities of PLA/SA blend coating treated minimally processed lily bulbs reduced by about 31 %, 21 % and 29 % on the 15th day, respectively. Total phenolic and quinone contents decreased respectively by 16 % and 55 % at the same time. Moreover, PLA/SA blend coating treatment eliminated the accumulation of malonaldehyde (MDA) while inhibited microbial growth of minimally processed lily bulbs.

CONCLUSIONS: These results showed PLA/SA blend coating could effectively maintain quality of minimally processed lily bulbs stored at 4 °C, and it might be a prospective technology. This article is protected by copyright. All rights reserved.
