摘要:

以银合欢种子胶为涂膜基质,甘油作为成膜助剂,配制成复合涂膜保鲜剂,研究常温(28~32℃),相对湿度68%~86%条件下该复合涂膜保鲜剂对杨梅品质及其生理生化变化的影响。结果表明:常温下经复合涂膜保鲜剂涂膜保鲜的杨梅与对照组相比,果实裂果率、失重率降低,果实好果率和硬度明显增加, 抑制了果实的呼吸率;有机酸、VC 等营养成分变化速度减慢,有效地降低MDA、花青素含量,使PAL 酶活性处于较低的水平,延缓了果实的衰老过程。

Abstract:

A compound film coating agent was prepared from Leucaena leucocephala seed gum as the basis material and glycerin as the humectant, and its fresh-preserving effect on Chinese bayberry was evaluated by measuring changes of sensory attributes and physiological and biochemical parameters of Chinese bayberry treated with it in advance during storage at room temperature (ranging from 28 to 32 ℃) and relative humidity (ranging from 68% to 86%). Compared with the control (untreated with the coating agent), treated Chinese bayberry fruits showed decreases in percentage of cracked fruits and weight loss percentage, significant increases in percentage of good fruits and firmness and suppressed respiratory intensity, slower changes of some nutrients, such as organic acids, vitamin C and so on, substantial reductions in MDA and anthocyanin contents, and lower PAL activity. Therefore, fruit senescence was retarded.

Key words: Chinese bayberry, Leucaena leucocephala seed gum, film coating, storage
