Problems solved by technology

[0002] Although this process can produce crystalline fructose with higher purity, there are still many problems in the production process: (1) the raw sugar (external sugar or raw sugar) contains more suspended solids, colloids, proteins, etc. Sugar impurities, when activated carbon is used for adsorption and decolorization, these non-sugar impurities can easily block or block the adsorption channel of activated carbon, resulting in a decrease in the adsorption capacity of activated carbon and increasing the input cost of activated carbon; (2) Some non-sugar impurities that pass through the plate and frame filter press, such as suspended solids, colloids, proteins, etc., will pollute the ion exchange resin in the subsequent process, Not only increases the load on the ion exchange resin, but also reduces the life of the ion exchange resin, and even causes resin poisoning in severe cases
The existence of these problems has seriously affected the production efficiency and production cost. For this reason, we have designed a method for preparing starchy grape pulp to solve the above problems.

Abstract

The invention discloses a preparation method of starch fructose syrup, comprising the steps of S1, hydrolyzing starch; S2, liquefying; S3, saccharifying; S4, filtering, and carrying out ion exchanging; S5, isomerizing; S6, evaporatively concentrating. The preparation method is simple and easy to perform; a microfilter membrane is used to filter sugar liquid, most non-sugar impurities, such as suspended matters, colloid and protein, can be filtered, it is avoided that in subsequent decoloring and ion exchanging, the sugar liquid blocks adsorbing channels of activated carbon or affects the service life of ion exchange resin, and the service life of the ion exchange resin is extended; the preconcentrating step is omitted, steps are lessened, and production efficiency is improved.
