Definitions
- the invention relates to a resistant dextrin and a preparation method thereof, and belongs to the technical field of food additive production.
- Dietary fiber is a kind of carbohydrate that cannot be digested by the human body. It is divided into two categories: water-insoluble and water-soluble fiber.
- the daily intake of dietary fiber recommended by international organizations is: The recommended standard of American Anti-Cancer Association is per person per day. 30 to 40 grams, the European Community Food Science Council recommends 30 grams per person per day. Recommended by the Chinese Nutrition Society: The daily dietary fiber intake of the human body is 25-35 grams.
- Resistant dextrin is a low-calorie dextran, low molecular weight water-soluble dietary fiber prepared from natural starch. Compared with other dietary fiber products, resistant dextrin has good acidity, thermal stability and high digestion resistance. Receptive, low glycemic index, low insulin index, low calorie, excellent characteristics such as prevention of dental caries.
- the Chinese patent document CN 104403009 A (Application No. 201410671093.0) discloses a preparation method of a resistant dextrin, which comprises the steps of: using acid-treated starch as a raw material, using sea sand as a heat transfer medium, and performing under high temperature conditions.
- the pyrolysis reaction obtains a crude pyrodextrin, and the crude pyrodextrin is refined to obtain a resistant dextrin product.
- Cipheral Patent Document CN103725732A (Application No. 201310743226.6) discloses a method for comprehensively utilizing wheat C starch to prepare resistant dextrin, comprising the following steps: (1) using wheat starch C starch slurry as raw material, adjusting pH with hydrochloric acid, sealing acidification (2) drying the acidified starch slurry after centrifugation; (3) pyrolysis in a roller heating furnace; (4) cooling to room temperature, adding an appropriate amount of distilled water to prepare an emulsion of a certain concentration range; (5) Simultaneous liquefaction and saccharification by double enzyme synergistic method; (6) decolorization with activated carbon and suction filtration to obtain sample solution; (7) alcohol solution sedimentation, centrifugation, supernatant distillation, alcohol recovery and recycling, precipitation and airflow drying, to obtain content It is 85%-90% resistant dextrins, and the product yield is 80%-90%.
- the above preparation methods still have shortcomings such as large bitterness, easy deliquescence, and poor fluidity, and cannot be widely used in foods and health care products, especially in the fields of high-end foods and health care products.
- the present invention is directed to the deficiencies of the prior art, and provides a resistant dextrin and a preparation method thereof.
- the resistant dextrin prepared by the invention is not easy to deliquesce, has good mouthfeel and fluidity, and is convenient for wide application in food, health care products, especially high-end foods and health care products.
- DP refers to Degree of Polymerization, which is an index for measuring the molecular size of a polymer, based on the number of repeating units, that is, the average number of repeating units contained in the polymer macromolecular chain.
- DP1 is a macromolecule having a degree of polymerization of 1
- DP2 is a macromolecule having a degree of polymerization of 2
- DP3 is a macromolecule having a degree of polymerization of 3.
- a resistant dextrin characterized by having a molar percentage of DP1 of ⁇ 1%, a molar percentage of DP2 of ⁇ 4.5%, a molar percentage of DP3 of ⁇ 7.0%, an average degree of polymerization of from 6 to 12, and a pH.
- the value is 3.0 to 6.0, and the molar percentage of dietary fiber is ⁇ 85%.
- the preparation method of the above resistant dextrin comprises the following steps:
- reaction material obtained in the step (1) is heated to 80 ° C to 120 ° C, and reacted at normal pressure for 2 to 4 hours to prepare an initial reaction material, and then added in a proportion of 1% to 10% by mass of the initial reaction material.
- the acid solution is stirred uniformly, and the temperature is raised to 140-200 ° C, and the gelatinization reaction is carried out for 15-30 minutes under normal pressure conditions to obtain a dextrin crude material;
- the acid in the step (1) and the step (2) is an edible acid; further preferably, the acid is selected from one of citric acid, malic acid, hydrochloric acid, phosphoric acid, sulfuric acid or Combination of two or more.
- the mass concentration of the acid in the step (1) and the step (2) is from 0.08 to 0.12%.
- the discoloration in the step (4) is as follows:
- the activated carbon is added at 0.5% to 1.5% of the dry basis mass, and the mixture is stirred for 25 to 35 minutes, and then filtered to obtain a liquid having a light transmittance of ⁇ 95%.
- the steps in the step (4) are as follows:
- Adjusting the temperature of the feed liquid before the inlet into the column is 35-55 ° C, and the pH of the column feed liquid is 4.0-5.0, to obtain an aqueous solution having a conductance of ⁇ 100 ⁇ s/cm and a light transmittance of ⁇ 98%;
- the concentration in the step (4) is concentrated by using six effects, and is concentrated to a solid content of 50 to 60% by mass.
- the purification in the step (4) comprises chromatographic purification, secondary decolorization, secondary separation, and secondary concentration.
- the chromatographic purification is adjusted to a pH of 6.0 to 7.0, and then chromatographically purified by a chromatographic separation system.
- the chromatographic separation operating conditions are a running pressure of 0.2 to 0.35 MPa, a temperature of 50 to 70 ° C, and a water consumption ratio of 1 : (1.2 ⁇ 1.5), feeding 1.2 ⁇ 1.5m 3 per hour.
- the secondary decolorization is added to the activated carbon by 0.5% to 1.5% by mass of the dry basis, and the mixture is stirred for 25 to 35 minutes, and then filtered;
- the second departure is as follows:
- Adjusting the temperature of the feed liquid before the inlet into the column is 35-55 ° C, and the pH of the column feed liquid is 4.0-5.0, and obtaining a secondary separation liquid having a conductance of ⁇ 100 ⁇ s/cm and a light transmittance of ⁇ 98%;
