Red-bud taro instant powder and preparation method thereof

Abstract

The invention belongs to the technical field of agricultural product deep and fine processing, and particularly relates to a red-bud taro instant powder and a preparation method thereof. According to the red-bud taro instant powder and the preparation method thereof, red-bud taros serve as a raw material and are cured, subjected to enzymolysis, dried and smashed to obtain a red-bud taro instant powder finished product, the dispersion time of the prepared red-bud taro instant powder can be as short as 15 s, the dispersion performance is high, and the instant effect is good. A composite method which combines food ingredients with a physical method is adopted to modify starch in the red-bud taros, only natural resources such as the red-bud taros and water are involved, no pollution on the environment can be caused, balanced nutrition is achieved, therefore, three effects are achieved at the same time by using the preparation method of the red-bud taro instant powder, and the red-bud taro instant powder can serve as an important resource for clean production and green food processing and thus has quite wide application prospects. A production technology of the red-bud taro instant powder is simple, mild in production process condition and friendly to the environment, and no strong acid and strong base are in use.

Description

technical field [0001] The invention relates to the technical field of intensive processing of agricultural products, in particular to a red bud taro instant powder and a preparation method thereof. Background technique [0002] Red bud taro is one of the varieties of taro, named for the reddish buds that come out. It is rich in protein, calcium, phosphorus, iron, potassium, magnesium, sodium, carotene, niacin, vitamin C, B vitamins and saponins and other ingredients; among the minerals contained in red bud taro, fluorine is The content is high, and it has the effect of cleaning teeth, preventing caries, and protecting teeth; its mucus protein can produce immunoglobulin (or antibody globulin) after being absorbed by the human body, which can improve the body's resistance. Therefore, traditional Chinese medicine believes that taro can detoxify, and it can inhibit and detoxify the carbuncle, swelling, poison and pain of the human body, including cancer poison, and can be used...

AI Technical Summary

Problems solved by technology

[0005] There are two main methods of traditional red bud taro powder production. One is to peel the bright red bud taro raw material, cut (grain) slices, bake (sun) dry and dehydrate, and crush to obtain the finished product. In the process, the product will be stained with barbecue smell or exposure to the sun, and destroy the unique aroma of taro, thereby reducing the quality of the product; the other is to beat the fresh red bud taro raw material, filter and precipitate, remove water, dry it, and crush it to get the finished product, but In this method, the slurry formed after beating is difficult to be dehydrated by the traditional method, and if the spray drying method is used for dehydration, because the slurry contains a large amount of plant fibers, the nozzles will often be blocked, making the production very troublesome and inefficient

Moreover, the surface hydrophilicity of the constituent molecules (hydrophobic proteins and fibers) of the whole powder of red bud taro produced by the above two methods is poor, and the mutual cross-linking rate is greater than the speed combined with water, so that the wettability of the whole powder of red bud taro is low, Fast settling, poor dispersibility and low solubility, easy to produce agglomerates

[0006] Therefore, improving the instant performance of the whole powder of red bud taro is the key issue to improve the convenience of the whole powder of red bud taro, but there is no report on the processing research of the instant whole powder of red bud taro
