| 摘 要： | 椰子花序汁液的采集耗时长,易腐败变质。文中研究了椰子花序汁液采集过程中的保鲜方法。采集前对采集环境进行清洁,使用食品蒸煮袋代替竹筒收集椰花汁可提高椰花汁的新鲜度,同时在收集前根据预计流量往采集容器中加入一定量的焦亚硫酸钠和柠檬酸,使椰子花序汁液中二氧化硫的浓度约为80mg/kg,柠檬酸浓度约为0.08g/100mL。采集9h后椰子花序汁液的酸度为0.09g/100mL(以乳酸计),比空白对照组降低了0.13g/100mL,所得椰子花序汁液室温放置24h后酸度缓慢增加至0.23g/100mL,比对照组降低了0.60g/100mL,并在36h才发酵产气,比对照组延迟了27h。

| Abstract: | Collection of coconut inflorescence sap takes long time and the sap is easy to decay. The preservation method of coconut inflorescence sap during collection was studied in this article. The collection environment was cleaned before collection; using retort pouch instead of bamboo canister could improve the freshness of coconut inflorescence sap. Meanwhile,sodium metabisulfite and citric acid were added before collection,the final concentrations of sulfur dioxide and citric acid reached 80 mg/kg and 0.06 g/1... |
