海藻酸钠和壳聚糖对莲藕贮藏效果及品质的影响
Effects of Sodium Alginate and Chitosan on Lotus Roots Quality and Preservation Effect
【摘要】 在常温(25℃)条件下,采用不同浓度的海藻酸钠(SA)和壳聚糖(CTS)涂膜保鲜剂对莲藕进行处理,对其采后贮藏效果和品质进行研究。结果表明:适宜浓度的SA和CTS涂膜处理可以有效的抑制莲藕表皮褐变,减小失重率,显著抑制莲藕VC、可溶性糖含量的降低和细胞膜透性升高。其中1.0%SA处理在抑制莲藕表皮褐变,减小失重率,抑制可溶性蛋白含量降低及细胞膜透性上升等方面表现最好;1.25%CTS和1.5%CTS处理在抑制莲藕VC和可溶性糖含量降低方面表现较好。
【Abstract】 This paper is to study the effects of different film coating antistaling agent〔sodium alginate(SA)and chitosan(CTS)〕on physiological metabolism and quality of lotus roots(Nelumbo nucifera Gaertn.)during postharvest storage at room temperature(25 ℃).The results showed that 2 kinds of film coating antistaling agent(SA,CTS)treatments could effectively prevent lotus root surface browning,reduce weight loss,and significantly inhibit contents of VC and soluble sugar decrease,and also cell membrane permeability increase.Among all treatments,1.0% SA had the best performance,1.25% CTS and 1.5% CTS performed better in inhibiting decrease of VC and soluble sugar contents of lotus root.
