Problems solved by technology

The substances with health-care physiological functions in the product are trisaccharides to pentasaccharides. The existence of a large amount of glucose and maltose interferes with the two physiological functions of the product, which are promoting the proliferation of bifidus factors and preventing dental caries, which seriously affects the efficacy and commercial value.

Embodiment 1

[0019] Operation: Prepare starch slurry according to the ratio of 1 part of dry starch to 3 parts of water (W / W), and add CaCl with 0.012% (W / W) of dry starch 2 . use Na 2 CO 3 Adjust the pH to 5.5. Add high temperature resistant α-amylase with a dry starch content of 0.04 (W / W), and stir evenly. Keep the temperature at 100°C, liquefy with a jet liquefier, and control the DE value to 9. The liquefied liquid stays in the laminar flow tank for 30 minutes, and samples are taken for iodine color test. After the iodine color test is qualified, the liquefaction is terminated and the enzyme is inactivated. Saccharification, filtration, decolorization, desalination, concentration, etc. are carried out according to the general process, and finally the product is obtained. The content of glucose in the product is 11.9%, trisaccharide to pentasaccharide is 70.1%, maltose is 18.0%, isomaltose is 20.5%, maltotriose is 4.0%, panose is 25.2%, isomaltotriose is 9.2%, four Sugar and abo...

Embodiment 2

[0021] Operation: Prepare starch slurry according to the ratio of 1 part of dry starch to 2 parts of water (W / W), and add CaCl with 0.02% (W / W) of dry starch 2 . use Na 2 CO 3 Adjust to pH 6. Add high temperature-resistant α-amylase with a dry starch content of 0.05% (W / W), and stir evenly. Keep the temperature at 130°C, liquefy with a jet liquefier, and control the DE value to 10. The liquefied liquid stays in the laminar flow tank for 40 minutes, and samples are taken for iodine color test. After the iodine color test is qualified, the liquefaction is terminated and the enzyme is inactivated. Saccharification, filtration, decolorization, desalination, concentration, etc. are carried out according to the general process, and finally the product is obtained. The content of glucose in the product is 12.2%, trisaccharide to pentasaccharide is 70.9%, maltose is 16.9%, isomaltose is 20.8%, maltotriose is 3.8%, panose is 24.8%, isomaltotriose is 9.6%, four Sugar and above is...

Embodiment 3

[0023] Operation: Prepare starch slurry according to the ratio of 1 part of dry starch to 3 parts of water (W / W), and add CaCl with 0.015% (W / W) of dry starch 2 . use Na 2 CO 3 Adjust the pH to 6.5. Add high temperature resistant α-amylase with a dry starch content of 0.07 (W / W), and stir evenly. Keep the temperature at about 130°C, liquefy with a jet liquefier, and control the DE value to 12. The liquefied liquid stays in the laminar flow tank for 60 minutes, and samples are taken for iodine color test. After the iodine color test is qualified, the liquefaction is terminated and the enzyme is inactivated. Saccharification, filtration, decolorization, desalination, concentration, etc. are carried out according to the general process, and finally the product is obtained. The content of glucose in the product is 11.4%, trisaccharide to pentasaccharide is 69.4%, maltose is 19.2%, isomaltose is 19.7%, maltotriose is 3.8%, panose is 24.8%, isomaltotriose is 9.6%, four Sugar ...

Abstract

The present invention discloses one method of controlling the ultralow DE value during reaction to control the molecular weight distribution of starch. The method consists of the following steps: mixing water and starch to form starch slurry and adding CaCl2 in the amount of 0.01-0.03 wt% of dry starch via stirring; regulating pH value of starch slurry; adding to the starch slurry heat resistant alpha-amylase in the amount of 0.03-0.08 wt% of dry starch via stirring; and reaction under the controlled conditions. The present invention is mainly improvement of available trisaccharide and pentasaccharide producing process via adopting available production process and increasing some apparatus.

Description

technical field [0001] The invention relates to a method for controlling the molecular weight distribution of starch sugar, in particular to a method for controlling the molecular weight distribution of starch by controlling the ultra-low DE value in the reaction process. Background technique [0002] In the prior art, starch sugar mainly containing three to five sugars is used in many fields, such as medicine, health products, food, etc. Patent application 96196047.7 provides a method for inhibiting bacteria of starch sugar compounds. One of the methods of starch sugar mainly containing trisaccharides to pentasaccharides is to synthesize from monosaccharides and disaccharides by organic chemical methods, and another way is to obtain it through the degradation of natural starch, glycolipids, and glycopeptides. People are also constantly inventing some new production methods. Patent application 99117102.0 provides "a process for producing oligosaccharides by enzymatic hydroly...
