中文摘要: 为降低冷冻咖啡浓缩块储存成本和运输成本,将其由冷冻保存,改为常温保存。利用添加适量的小苏打或 β环状糊精、黄原胶的混合稳定剂来降低咖啡浓缩液中形成的沉淀。发现添加 0.05 %小苏打、0.01 %黄原胶和 0.03 %β-环 状糊精的混合稳定剂时咖啡浓缩液的稳定性较好;通过检测 25、40、55 ℃ 3 个温度下长期保存咖啡浓缩液的稳定性,最 终确定 25 ℃为最佳保存温度。
Abstract:To reduce the cost of storage and transportation, the method of storage of coffee concentrate would be changed from cryopreservation to room temperature. Baking soda and the mixture of β-cricoid dextrin and xan- than gum were used to improve the stability of coffee concentrate.The results showed that the coffee concentrate had good stability by adding 0.05 % baking soda,0.03 %β-cricoid dextrin and 0.01 % xanthan gum. By measur- ing the stability of the coffee concentrate after a long-time storage at 25,40,55 ℃, 25 ℃ was determined as the optimum storage temperature.
