Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the continuous chromatographic separation system adopted in this embodiment has 20 built-in separation units, and calcium ion chelating resin is filled in each separation unit; the continuous chromatographic separation system is divided into five regions, and each region is composed as follows:

[0028] Adsorption zone (10#-11# separation unit): Contains 2 separation units, adopts the forward series feeding method, the raw material liquid passes through the 11# separation unit after the two separation units in turn, and the intermediate feed liquid from the 11# separation unit enters the intermediate material tank;

[0029] Washing area (5#-9# separation unit): Contains 5 separation units. The separation unit adsorbed by the adsorption area is washed in a forward series with pure water, and the washing liquid f...

Abstract

The invention discloses a method for separating glucose and allulose from high fructose corn syrup, which is characterized in that the separation of glucose and allulose is realized by continuous chromatographic separation by using a continuous chromatographic separation system filled with calcium ion chelating resin. With the above technical scheme, the method for separating glucose and allulose by continuous chromatographic separation of the invention has the beneficial effects of compact equipment, simplified system, reduced pipelines, and less land occupation; because of the continuous running under non-interrupted operation, the product components and concentration are maintained to be stable basically; the method has good operating flexibility, can automatically adjust the rotation speed according to the change of production loads; the operation cost and the equipment investment are low; the separation effect is good; the separated high fructose corn syrup has a high purity; a mixed solution of allulose and fructose can be obtained with a high concentration and high value, and a high-concentration allulose solution can be obtained by further separation and concentration; and the method has significant economic benefits.

Description

technical field [0001] The invention relates to the field of functional foods, in particular to a method for separating glucose and allulose in fructose syrup. Background technique [0002] In recent years, functional food has become the focus of attention of consumers, and it is also the focus of research and development of food practitioners. The increase and younger age of people with diabetes, obesity and cardiovascular diseases make functional sweeteners with low calories and more functional nutritional properties become a hot spot of attention. [0003] Allulose is a kind of natural ketohexose which is relatively rare in nature, and belongs to a kind of rare sugar. The International Society of Rare Sugars (ISRS) defines rare sugars as "a class of sugars and their derivatives that exist in nature but in very small amounts". The sweetness of allulose is similar to sucrose, the sweetness is comparable to fructose, and the caloric value is only 0.007kal / g, so it is calle...
