Abstract
The invention relates to the field of flour and especially relates to a preparation method of milled whole wheat flour using a stone mill. The product is obtained by impurity removing, primary separating, secondary separating, microwave drying, repeatedly milling, sterilizing and packaging. The different specific gravities between wheat germs and wheat brans are used, the germs and the wheat brans are separated, and at the same time, the microwave drying and oil absorbing papers are used to treat the wheat germs. The preparation method reduces the effect of the wheat germs on the product quality of the flour and thereby obtains the products which are richer in nutrition and good in tastes.
Description
Technical field
The present invention relates to flour field, the manufacture method of especially a kind of stone grinder whole wheat flour.
Background technology
Flour is a kind of powder worn into by Semen Tritici aestivi, is the staple food of northern China most area, and existing flour is mostly refined flour, and the materials of wheat wheat grain of flour is mainly made up of three parts: Testa Tritici is wrapped in the outer 18%-25% accounting for grain weight；Wheat grain rely germinate plumule only account for 1%-2%；Endosperm accounts for 80%.Aleurone adhesion is also had between endosperm and Testa Tritici.Existing most of flour is to make Testa Tritici, Fructus Hordei Germinatus separate with endosperm and by levigate for the endosperm refined flour made through flouring technology processing wheat grain.Such flour has been abandoned the more Testa Tritici of fiber and has been improved mouthfeel, but has given up nutritious plumule simultaneously.
Wholewheat flour be Intact wheat when pulverizing, only pass through and pulverize, and be not necessary to through removing wheat bran program, be that Intact wheat contains wheat bran and the whole grinds of plumule and is namely called wholewheat flour.Wheat bran in conventional Semen Tritici aestivi is not paid attention to by people, is therefore often taken as feedstuff to use.Now pass through multinomial research, demonstrate the cellulose that the wheat bran in Semen Tritici aestivi contains high nutritive value, in flour, make whole-wheat bread as often mixed, eat for consumers in general, brown bread human body can be made to keep fit and have vigor, so should be widelyd popularize edible.Yet with Fructus Tritici aestivi contains oils and fats, it is easy to oxidation, cause becoming sour of flour, become sour is exactly in the middle of Oxidation of Fat and Oils process, some fatty acids produced, some abnormal flavour caused, some harmful materials, thus affecting the shelf-life of flour, enzymatic activity inside Fructus Tritici aestivi is stronger simultaneously, and be that amylase is more, viscoelasticity after flour likely can be caused when not removing to add water is bad, and oils and fats has deleterious effect for the viscoelasticity after adding water time higher, whole wheat flour is made according to conventional mechanical methods, owing to the high temperature in manufacturing process can cause the loss of various benefit materials in flour, and adopt stone grinder method to prepare whole wheat flour and can cause that viscoelasticity and the shelf-life of whole wheat flour are produced considerable influence by the oils and fats in Fructus Tritici aestivi and enzyme.
Summary of the invention
The present invention is directed to the problems referred to above and propose the manufacture method of a kind of stone grinder whole wheat flour, it is possible to effectively remove enzyme and the oils and fats impact on flour in Fructus Tritici aestivi, ensure that Semen Tritici aestivi nutrition is not run off simultaneously.
To achieve these goals, the technical solution used in the present invention is, the manufacture method of a kind of stone grinder whole wheat flour comprises the following steps:
A. remove impurity: remove the foreign material in Semen Tritici aestivi；
B. separate for the first time: utilize stone grinder to carry out extruding pulverizing the Semen Tritici aestivi after removing foreign material, then obtaining powder a and solids b by screen cloth；
C. secondary separation: solids b is put in water and is stirred, wheat bran will float on the surface of water and Fructus Tritici aestivi will sink to the bottom, obtain Fructus Tritici aestivi and wheat bran thus separating, then Fructus Tritici aestivi be dried removal surface water；
D. microwave drying: by being placed on oil-Absorbing Sheets through dry Fructus Tritici aestivi after secondary separation, utilize power at 500～800W microwave drying 2～4min, and utilize microwave that wheat bran is dried；
E. many pulverizing: utilize stone grinder to carry out repeatedly pulverizing after mixing with the powder a obtained in step B after being cooled to room temperature by the Fructus Tritici aestivi of microwave drying, wheat bran, it is ensured that particle diameter is more than 90 orders；
F. sterilization, packaging: undertaken sterilizing, packing by the particle diameter obtained after pulverizing powder more than 90 orders, obtain product.
As preferably, the screen cloth in described step B adopts 20 eye mesh screens.
As preferably, also having between described step B and described step A and moisten step in advance.
As preferably, the microwave power in described step D, Fructus Tritici aestivi processed is 600～700W, and drying time is 3～3.5min, wheat bran after microwave drying water content 8%～13%.
Fiber content is high, nutritious, adopt stone grinder to process the low temperature environment having ensured in production process to adopt method of the present invention to have the advantage that, thus decreasing damage and the loss of nutrient substance, Fructus Tritici aestivi adopted while microwave drying simultaneously and utilize oil-Absorbing Sheets to carry out oils and fats absorption, effectively reduce oils and fats contained by product and the activity of enzyme contained by plumule, make shelf life of products longer, effectively prevent the defect adding plumule.
