Description

Whole nutrition powder containing wheat resistant dextrin for aged people and preparation method thereof Technical Field The invention belongs to the technical field of functional foods, and particularly relates to full-nutrition powder for the aged population and a preparation process thereof. Background As the population ages, the need for full nutritional supplements for the elderly has increased, and related nutritional products have been continuously updated. The current senile nutrition powder on the market focuses on basic nutrition ratio, for example, patent CN103300282A provides a senile nutrition powder containing soybean oligopeptide and a preparation method thereof, wherein the soybean oligopeptide is taken as a main nutrition component, one or more of 45-75 parts of wheat flour, rice flour or corn flour, 10-30 parts of one or more of oat flour, buckwheat flour or pearl barley flour, 3-5 parts of vegetable oil and 5-7 parts of fruit and vegetable powder are added. The above senile nutrition powder contains carbohydrate such as wheat flour, rice flour or corn flour, which can cause blood sugar fluctuation, and adversely affect the elderly and special people with glycolipid metabolism disorder. The existing nutrition powder has the common defects that (1) the brewing performance is poor, partial high-protein full nutrition powder is easy to generate caking during the brewing process, the dispersing speed is low, and the use experience of the old is affected. (2) The digestion speed is high, the starch component in the conventional total nutrient powder is easy to digest quickly, and the powder is not friendly for the old who needs to stabilize the blood sugar level. (3) Insufficient stability, and is easy to be wetted and agglomerated in the long-term storage process. The resistant dextrin is prepared from starch, and is a low-calorie dextran prepared by extracting and refining indigestible components of baked dextrin by industrial technology. However, resistant dextrins from different starch sources have different efficacy, for example corn resistant dextrin (CZAPI) is a low molecular weight water soluble dietary fiber prepared by a modification process of corn starch. CZAPI can bind to some protease in digestion to form stable complex, thereby protecting vitamins, nucleic acids, palmitic acid, etc. from inefficient decomposition by digestive enzymes. Therefore, the corn resistant dextrin can be applied to the fields of food additives, drug indissolvable slow release agents, bioreactors and the like, and plays roles in protecting and assisting other substances. The wheat resistant dextrin (WHEAT AMYLASE TRYPSIN inhibit, ATI for short) is also a low molecular weight water-soluble dietary fiber, and can inhibit the activity of wheat amylase, so that the digestion speed of starch is slowed down, and the carbohydrates in the wheat are gradually released, thereby being beneficial to maintaining the blood sugar level for a long time. Disclosure of Invention Aiming at the defects existing in the prior art, the first purpose of the invention is to provide the whole nutrition powder for the aged containing the wheat resistant dextrin, which can remarkably improve the dispersibility, reduce the caking rate, remarkably increase the content of Resistant Starch (RS) and reduce the proportion of Rapidly Digestible Starch (RDS). Can meet the nutritional requirements of special people such as the elderly and the glycolipid metabolic disorder. The second purpose of the invention is to provide a preparation method of the senile total nutrient powder. The technical scheme for realizing the purposes of the invention is as follows: the total nutrient powder for the aged containing the wheat-resistant dextrin comprises the following components in parts by mass: 25-45 parts of solid corn syrup, 5-30 parts of starch-based resistant dextrin, 10-20 parts of protein, 10-12 parts of vegetable fat powder, 8-12 parts of maltodextrin, 0-0.3 part of ellagic acid, 5-8 parts of maltitol, 1-2 parts of medium chain triglyceride, 0.1-0.5 part of DHA powder, 1-5 parts of compound mineral substances and 1-3 parts of compound vitamins. The whole nutrition powder is added with the resistant dextrin, and correspondingly, maltodextrin and solid corn syrup are also added, and the whole nutrition powder is matched with the resistant dextrin to realize 'fast and slow combination' of energy, prolong satiety and stabilize blood sugar. On the other hand, the technology utilizes the good film forming property and caking resistance of maltodextrin and solid corn syrup, and the maltodextrin is used as a carrier in dry mixing, so that the particle agglomeration caused by high-proportion resistant dextrin is improved, and the fluidity and the brewing feel of powder are improved. Maltodextrin has the characteristics of high sweetness, high solubility and low viscosity, is also a carbohydrate which is easy to absorb, and can be added into the full nut
