Abstract: Processes for extracting three sugars, fructose, sucrose and glucose, from dates are disclosed. Pitted dates are frozen and subdivided into particles. The particles are contacted with a heated water solution to extract the sugars from the date fibers. The sugar enriched water solution is separated from the date fibers by passing the water solution through one or more milli-screens. The sugar enriched water solution may be purified, and also may be treated to reduce the water content. The sugar solution containing the three sugars is a novel food product which can be used as a sweetener, for example, for sweetening soft drinks. Alternatively, the liquid product may be freeze-dried, vacuum oven-dried or spray-dried to produce a novel solid product containing the three sugars. The date fibers are dewatered, and admixed with ground date seeds to produce another novel food product.

Abstract translation: 公开了从日期提取三种糖，果糖，蔗糖和葡萄糖的方法。 腌制的日期被冻结并细分成颗粒。 颗粒与加热的水溶液接触以从日期纤维中提取糖。 通过使水溶液通过一个或多个毫米筛，将富含糖的水溶液与日期纤维分离。 可以纯化富含糖的水溶液，并且还可以处理以降低含水量。 含有三种糖的糖溶液是可用作甜味剂的新型食品，例如用于甜味软饮料。 或者，液体产物可以被冷冻干燥，真空烘干或喷雾干燥以产生含有三种糖的新型固体产物。 日期纤维脱水，并与地面日期种子混合以产生另一种新型食品。
