在所有可用的浓缩方法中,冷冻浓缩提供了最高的除水选择性,因为冰晶只含有水。
完全分离这些冰晶会导致在非常低的加工温度下特定地去除水。在零下温度下非常温和的浓度可以保持产品的新鲜度,并且实际消除了所有生物降解。
由于结晶过程对水具有高度特异性,并且不存在气相,因此所有挥发性香气和风味都将保留在液体浓缩物中。
重要特征:
食品溶液的冷冻浓缩与化学品的熔融结晶的区别在于,液体是水而不是化学品的溶液,产品是浓缩物而不是分离的(冰)晶体。
冷冻浓缩设备遍布全球各地,脱水能力从每年 200 吨到 200,000 吨不等,可处理从小批量特种产品到大型商品的各种产品,服务于可分为两大组的不同工业工艺:
食品浓缩
废水
