Abstract

The invention discloses easy-brewing instant yam powder and a preparation method thereof, and belongs to the field of food processing. With fresh yam as a raw material, the easy-preparing instant yam powder disclosed by the invention is prepared by adopting a granulation process after washing, peeling, steaming, drying, crushing, adding other food materials or not. The yam powder prepared by adopting the method is rich, mellow, outstanding in ripe sweet flavor of the yam, good in reconstituability and rich in nutrition, thus being a good choice for breakfast of students and extra meal of white-collar workers.

Description

One easily reconstitutes instant Chinese yam powder and preparation method thereof

Technical field

The present invention relates to a kind of production method of instant Chinese yam powder, particularly relate to a kind of with fresh Chinese yam for raw material, through steaming technique, the production method easily reconstituting instant Chinese yam powder that processes of granulating process, belong to food processing technology field.

Background technology

Chinese yam is the perennial climing property rhizome plants of Dioscoreaceae (Dioscoreaceae) Dioscorea (Dioscorea), has edible, medicinal and health value.The history of the cultivation and utilization of Chinese yam can trace back to the Classic of Mountains and Rivers Guo Pu biography in the Western Jin Dynasty, and the herbal ancient books and records such as amplification on Canon of Materia Medica, " figure is through book on Chinese herbal medicine ", " Tang materia medica ", Important Arts for the People's Welfare are all on the books.Herbal pharmacopeia Shennong's Herbal row Chinese yam is the earliest top grade medicinal material; " Japan hanako materia medica " is recorded Chinese yam and is helped the five internal organs, strengthening the bones and muscles, and long will is calmed the nerves, and master lets out smart being good for and dies; Compendium of Material Medica records Chinese yam kidney-nourishing gas, strengthening the spleen and stomach, stopping leak dysentery, and reduce phlegm saliva, profit fur.

Chinese yam block root meat is fine and smooth, containing a large amount of glutinous albumen, glutinous polysaccharide, starch and amino acid, vitamin etc., has good edibility, can be made into multiple nourishing food.Modern medicine study shows, Chinese yam sticks albumen and has special health-care effect to human body, can prevent the sedimentation of fat on cardiovascular, keeps blood vessel elasticity, stops atherosclerotic to occur too early; Subcutaneous fat deposits can be reduced; Prevent the atrophy of connective tissue, prevention rheumatoid arthritis etc.Many nourishing prescriptions, as Liuwei Dihuang Wan, Qiju Dihuang Wan, guipi decoction, the Chinese medicines such as shenling baizhu powder all contain Chinese yam composition.

Although Chinese yam has excellent edible health function, the food processing of yam flour class is uncommon.On the one hand, the easy chafe of the vegetable soda in Chinese yam mucus produces allergy and itches.On the other hand, digestive discomfort and diarrhoea may be caused when reconstituting without the yam flour of shortening.In addition, because Chinese yam is rich in starch, no matter fecula or ripe powder, easily lumps when reconstituting and not easily stirs out, be inconvenient to eat.

Existingly reconstitute nutrient powder patent, relate to yam flour, as ZL 200810304447.2 " tuckahoe nutrient powder and preparation method thereof ", 200510122385.X " walnut Chinese-yam powder and production method thereof ", ZL 200610032123.9 " a kind of nutrient breakfast food and production technology thereof ", ZL 201110188469.9 " a kind of composite jujube powder and processing method thereof " etc., yam flour is only as a kind of batching, but not major ingredient, ratio is about about 20%.And take Chinese yam as the patent of primary raw material, do not relate to its brew, as 200710093205.9 " a kind of natural health preserving yam powders ", ZL 95112051.4 " a kind of method for processing active Chinese yam flour ", ZL 201010532456.4 " a kind of yam flour and preparation method with health care " etc.

The cooking method of yam flour comprises poach, expanded, frying or microwave drying etc.The present invention adopts and steams technique, avoids Chinese yam directly contact with water and lose nutritional labeling soluble in water, and amount of cure is easy to control handled easily, and is convenient to later stage drying process.Laboratory research shows, through steaming the yam flour of processing, the ripe Flavor of Chinese yam is strong, and mouthfeel is aromatic, and flavour is long thick and heavy; And brew and storage stability are obviously better than Rhizoma Dioscoreae powder.The present invention aims to provide one and easily reconstitutes instant Chinese yam powder, and the ripe Flavor of Chinese yam is given prominence to, and aromatic, flavour is pure, and wherein yam flour content can reach more than 50%; Adopt granulating process, make the loose particles porous of yam flour, greatly add the contact area with water, easily reconstitute, instant edible.

Summary of the invention

The problem of easy conglomeration when the yam flour existed based on above-mentioned prior art reconstitutes, the invention provides a kind of with fresh Chinese yam for raw material, through steaming technique, granulating process is prepared from easily reconstitutes yam flour, and ripe Chinese yam local flavor is given prominence to, instant edible.

The present invention adopts following technical scheme: fresh Chinese yam-clean-peel-steam-cut into slices-dry-pulverize (70-100 order)-yam flour-(or not adding)-add water the mediation of other food materials mixing-granulation-drying.Be described for the instant Chinese yam powder adding other food materials below:: yam flour 10%-100%, puffed rice powder 5%-15%, coixlacrymajobi powder 3%-15%, white granulated sugar 5%-10%, sesame, peanut, walnut, milk powder add in right amount in formula by weight.Concrete steps are: 1) prepare yam flour: peeling after fresh Chinese yam cleaning, and steaming to the complete gelatinization of Chinese yam, cut into slices after cooling, being dried to moisture is less than 5%, pulverizes and makes 70-100 object yam flour, for subsequent use.2) other food materials preparation: a, rice, the seed of Job's tears to be cleaned, dry, pulverizing after extrusion and making granularity is 70-100 object rice meal, coixlacrymajobi powder, for subsequent use.The preparation of b, sesame, peanut, walnut: peanut, sesame, walnut are baked out fragrance, mixes with yam flour, is crushed to 70-100 order fine powder, for subsequent use.Prepared by c, Icing Sugar: white sugar powder is broken to Icing Sugar, for subsequent use.3) appropriate milk powder mixes with above-mentioned food materials by mixing.4) granulation, drying: the above-mentioned powder mixed is granulated, granulate through granulating process, granulation mode can adopt extrusion granulator, dry granulation, wet-mixing to granulate and boiling granulating, and Chinese yam particle dewaters through the mode such as heated-air drying, microwave drying, and packaging is finished product.

Yam flour prepared by the present invention, Chinese yam ratio can reach more than 50%, aromatic taste, and the ripe Flavor of Chinese yam is strong, and mouthfeel is lubricious, nutritious, and brew is good, instant.
