High-rehydration konjac dietary fiber food and preparation method thereof

Abstract

The invention provides a high-rehydration konjac dietary fiber food and a preparation method thereof. According to the invention, konjac glucomannan (KGM) is added into a water solution of sodium carboxymethyl cellulose or sodium carboxymethyl starch; the mixture is sufficiently stirred, such that a paste is obtained; KGM is subjected to deacetylation by using a calcium hydroxide solution, such that an irreversible gel intermediate is obtained; the irreversible gel intermediate is subjected to treatment methods such as freezing, thawing, dehydration drying, and the like, such that a plurality of tiny gaps are formed in the product. With the method, the prepared konjac dietary fiber food has rehydration rate up to 8-15 times, and has high konjac dietary fiber content. The product is convenient for transportation and storage, and is convenient for everyday carrying. Before eaten, the product is rehydrated, such that a good taste is provided, and large water drinking is not needed. Under a safe condition, enough konjac dietary fiber can be easily obtained. With the food and the preparation method, important significance is provided for healthy diet of human.

Description

Technical field [0001] The invention relates to a konjac dietary fiber food and a manufacturing method, in particular to a food with high rehydration and high konjac dietary fiber content and a manufacturing method. Background technique [0002] It is recognized throughout the world that insufficient dietary fiber intake is the main dietary source of metabolic diseases such as hyperlipidemia, cardiovascular and cerebrovascular diseases, diabetes, obesity, constipation, fatty liver, gout, endocrine disorders, etc., in high sugar, high fat and high protein, etc. This is especially true in high-calorie diets. Modifying traditional foods with dietary fiber, balancing the diet, suppressing the side effects of excessive carbohydrates, fats and proteins, reducing the glycemic index of foods, ensuring benign metabolism, effective detoxification, and maintaining a healthy human micro-ecological environment have become the core demands of a healthy diet. [0003] The nutritional medicine co...

Problems solved by technology

If the intake is small, the effect is not obvious; if the intake is large, drinking a lot of water will easily hinder normal eating and cause malnutrition

[0011] 3. A few foods contain a lot of dry glucomannan products, but they stick to the teeth after eating, the taste is uncomfortable, and a lot of drinking water is also required

So far, there is no konjac dietary fiber food in the world that is easy to quantify, easy to transport and store, easy to carry, has a good taste, and is well compatible with other ingredients and food raw materials, and can ensure that the human body can take in enough and complete functions
