Abstract
The invention discloses iron rod yam flour rich in water-solubility dietary fibers and a preparation method thereof, and the iron rod yam flour is characterized by comprising flour, iron rod yam fine powder, polydextrose and silicon dioxide, wherein the mass of the added iron rod yam fine powder is 50% of that of the flour; the mass of the added polydextrose is 8%-15% of that of the flour; and the mass of the added edible grade silicon dioxide is 1% of that of the flour, and the iron rod yam flour rich in water-solubility dietary fibers is obtained after the dry mixing of the components. The iron rod yam flour rich in water-solubility dietary fibers has the advantages that the nutrition is rich, the dietary fibers are dissolved into one of the daily edible staple foods for people, and sufficient dietary fiber nutrient substances can be intaken directly in daily life.
Description
Technical field
The present invention relates to a kind of flour that contains dietary fiber and preparation method thereof, particularly a kind of water-soluble dietary fiber iron rod yam flour and preparation method thereof that is rich in.
Background technology
Dietary fiber is as " the seventh-largest nutrient " and new ingredient, reach the application in practice in 30 years through developed countries such as America and Europe, Japan, its healthy functions is constantly disclosed by nutrition circle and medical circle, and its remarkable nutritive value is just constantly praised highly by food enterprise.Especially as the functional ingredient of food, promptly can reinforcing fiber, balanced nutrients; Can reduce heat again, keep intestinal health.
Dietary fiber is divided into two kinds, water-soluble dietary fiber and insoluble diedairy fiber.The expert thinks that the dietary fiber of absorption must guarantee the water-soluble dietary fiber more than 10%.And the dietary fiber that China resident takes at present is still based on insoluble diedairy fiber.
Polydextrose is as a kind of novel dietary fiber and formulation adjuvant, water-soluble fully, be mainly used in the functional foods such as low-yield, high fiber, can not influence the local flavor and the quality of product, at present, surpass 57 state approval polydextroses in the world and be applied in the food, polydextrose can join in the various Flour product such as instant noodles, biscuit widely, and the adding of polydextrose can also have clear improvement to the gluten structure.
It is 27 grams that the World Food Programme requires the minimum warning line of dietary fiber intake every day, and the total dietary fiber intake that U.S. FDA is recommended is 30-35 gram every day, and China NI everyone dietary fiber every day intake of suggestion Chinese residents is 30.2 grams.Wherein, the dietary fibers of 27 grams are equivalent to 13.5 kilograms of 5 kilograms of edible rice, tomato 2.75, little rape.As seen every day will from three meals in a day in the picked-up q.s dietary fiber relatively the difficulty.And human body is not taken in enough dietary fibers and gastrointestinal discomfort, habitual constipation, defecation effort, dry and hard excrement, hyperglycaemia, high fat of blood, cardiovascular and cerebrovascular disease can be occurred.So need the food of more edible intensification diet fibers to replenish, reach enough intakes.
Yet every day, the dietary fiber food of concentrated edible need select to be fit to own health products, extra work such as reminder time every day, and great majority need the working clans of additional enough dietary fibers to ignore easily, cause nutritional deficiency.Flour is the most important food of Chinese residents, is made into the staple food in the daily lifes such as steamed bun, noodles, bread, so Chinese residents can guarantee the flour consumption that every day is higher.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of water-soluble dietary fiber iron rod yam flour and preparation method thereof that is rich in, add water-soluble dietary fiber and make the daily edible flour of people have high nutritive value, people need not to take in other additional dietary fibers.
The present invention realizes by following technical scheme:
A kind of water-soluble dietary fiber iron rod yam flour and preparation method thereof that is rich in, composition proportion comprise that flour, adding quality are that the iron rod yam fine powder of described flour quality 50%, polydextrose, the adding quality that the adding quality is described flour quality 8%～15% are the food grade silica of described flour quality 1%.
A kind of preparation method who is rich in water-soluble dietary fiber iron rod yam flour is to prepare by following method:
(1) iron rod yam is handled and oven dry: the iron rod yam of fresh results is removed foreign material, selected fresh iron rod yam, and the flowing water flushing is thinly sliced with slicer, again the iron rod yam thin slice is fed hot water, cleans and removes slurry;
(2) iron rod yam oven dry and pulverizing: the iron rod yam thin slice after the processing is dried, 40～70 ℃ of baking temperatures, 3～6 hours drying times; The iron rod yam dry plate is pulverized with pulverizer, obtains iron rod yam dry powder after the pulverizing, if the moisture of iron rod yam dry powder, re-uses hot blast continuous dryer oven dry more than 5%, up to moisture below 5%;
(3) processing of iron rod yam dry powder: moisture sieves through 100～120 purposes at the iron rod yam dry powder below 5%, obtains iron rod yam meal and iron rod yam fine powder, and the iron rod yam meal is pulverized again;
(4) mix: do iron rod yam fine powder and polydextrose mixed in flour, the adding quality of iron rod yam fine powder is 50% of a flour, it is 8～15% of flour that polydextrose adds quality, and anti-caking agent food grade silica 1 % puts into dry mixing device with mentioned component and does mixed.
The thickness of iron rod yam thin slice is below the 0.25cm in the described step (1).
Beneficial effect of the present invention is:
1, selects flour as matrix, strengthened water-soluble dietary fiber content, make people when taking in staple food, guaranteed the picked-up requirement of dietary fiber, do not need extra complementary diets fiber electuary.
2, the viscoplasticity that adds affiliation influence surface powder of insoluble diedairy fiber and extensibility cause Flour product to be difficult for being shaped, and the present invention adds polydextrose and not only do not have this influence, can also improve the gluten structure.
3, a kind of processing method of iron rod yam is provided, has avoided the not long waste that causes of holding time, improved the added value of iron rod yam.
4, the high-quality dietary fiber polydextrose has remedied the shortcoming of Chinese yam inducing astrigency, and it is edible that product of the present invention also is fit to constipation person very much.
5, the flour that obtains according to the present invention is fit to women's cosmetology, anti-ageing, nourishing, tonifying middle-Jiao and Qi; Stomach can be regulated, the requirement that the women keeps body weight can also be satisfied.
