Abstract
The invention discloses a method for producing yeast powder being rich in beneficial metallic elements by utilizing beer waste yeast, which comprises the following steps: (1) sufficiently mixing fresh beer waste yeast and a culture medium which contains beneficial metal salt according to a solid-liquid ratio of 1:1 and then stirring the mixture to be fermented for 6-12 hours under the temperature of 25-35 DEG C; (2) eliminating water contained in fermentations obtained from the (1) step and obtaining the yeast powder being rich in the beneficial metallic elements after drying and crush. The yeast powder being rich in the beneficial metallic elements is produced by the method, thus the invention not only has high yield and high biological activity, but also simplifies a step of strain expanding cultivation and reduces the production cost; the yeast powder being rich in beneficial metallic elements produced by the method has aromatic odor, the crude protein content of the yeast powder can reach 40-50 percent, the chromium, iron and zinc contents of the yeast powder can respectively reach 800-1700 mg/kg, 400-900 mg/kg and 800-1100 mg/kg, wherein organic chromium, iron and zinc contents respectively reach more than 85 percent, 80 percent and 77 percent.
Description
One, technical field
The invention belongs to yeast powder manufacturing technology field, be specifically related to a kind of method of utilizing the beer waste yeast manufacturing to be rich in the beneficial metallic elements yeast powder.
Two, background technology
As everyone knows, elements such as chromium, zinc, iron all are essential beneficial metallic elements of organism, have great significance to keeping the normal physiological metabolism function of organism.Organism lacks chromium can show cholesterol or symptoms such as blood sugar increasing, growth retardation, immunity degradation, fecundity decline and the lost of life.And a lot of basic physiology activities of zinc and organism are closely related, can keep the body eubolism, promote the growth of health and intelligence, but also have the effect of strengthening immunity.And iron is to constitute organism oxyphorase, myohaemoglobin, and the prothetic group of cytopigment enzyme system and catalatic moiety play an important role in tissue respiration and biological oxidation process.If organism ferro element insufficiency of intake can cause growth retardation, lower immune function.But organism often has gastrointestinal upset to the mineral ion form receptivity extreme difference of these metallic elements, even causes symptoms such as gastrointestinal hemorrhage.And organism will be higher than inorganic form to the absorption and the biological utilisation ability of the metallic element of organic form (promptly being combined on the biological organic substance).At present, the yeast powder of having seen on the market that is rich in metallic element all is to get by the strain fermentation that long-term breeding obtains, and production cost is higher, is difficult to apply widely.Studies show that cereuisiae fermentum has accumulation ability preferably to above-mentioned useful metal ion, and inorganic form can be converted into organic form, helps organism and absorbs.Brewing industry produces that important by product---beer waste yeast is not but recycled fully, lets alone contaminate environment, has caused great waste but for a long time.
Three, summary of the invention
The purpose of this invention is to provide a kind of method of utilizing the beer waste yeast manufacturing to be rich in the beneficial metallic elements yeast powder, adopt this method not only can utilize the beer waste yeast resource fully, reduce and pollute and waste, and production cost is lower.
For achieving the above object, the technical solution used in the present invention is: this method comprises the steps:
1. with young beer waste yeast and the solid-to-liquid ratio thorough mixing of the substratum that contains useful metal-salt, stir fermentation 6-12 hour down in 25-35 ℃ according to 1: 1;
2. remove the moisture of going up step gained fermented product, promptly get after the drying and crushing and be rich in the beneficial metallic elements yeast powder.
Above-mentioned useful metal-salt is a chromium chloride, and its add-on is to make chromium ion concentration in the substratum reach 100-400mg/L to get final product, and preferential 300mg/L is in order to preparation Rich chromium yeast powder.
Above-mentioned useful metal-salt is a ferrous sulfate, and its add-on is to make iron concentration in the substratum reach 50-300mg/L to get final product, and preferential 100mg/L is in order to preparation ferrum-rich saccharomyces cerevisiae powder.
Above-mentioned useful metal-salt is a zinc sulfate, and its add-on is to make zinc ion concentration in the substratum reach 200-600mg/L to get final product, and preferential 500mg/L is in order to preparation Zinc-rich saccharomyces cerevisiae powder.
Above-mentioned substratum is a 6-12 ° of wort, preferential 10 ° of worts.
Above-mentioned leavening temperature is 28 ℃.
The 2. middle moisture that adopts centrifugation to remove fermented product of above-mentioned steps.
The drying of above-mentioned steps in 2. be meant nature dry to contained humidity less than 10%.
The drying of above-mentioned steps in 2. be meant 50 ℃ of following hot-air seasonings to contained humidity less than 10%.
The present invention is that the substratum that utilizes the beer waste yeast contain a large amount of protein and VITAMIN and added useful metal-salts such as chromium, zinc and iron is raw material, makes through the short-term fermentation and is rich in the beneficial metallic elements yeast powder.The yeast powder of gained promptly can replenish the nutritive ingredients such as amino acid of organism, can replenish the essential metallic element of organism again, has a good application prospect.Its advantage is as follows: 1, utilize manufacturing of the present invention to be rich in the beneficial metallic elements yeast powder, and not only output height, biological activity height, but also simplified the step of strain expanded culture, reduced production cost; 2, manufacturing of the present invention be rich in the aromatic odour that the beneficial metallic elements yeast powder has cereuisiae fermentum, its crude protein content can reach 40～50%.The chromium content of Rich chromium yeast powder can reach 800～1700mg/kg, and wherein organic chromium content can reach more than 85%; The iron level of ferrum-rich saccharomyces cerevisiae powder can reach 400～900mg/kg, and wherein organic iron level can reach more than 80%; The zinc content of Zinc-rich saccharomyces cerevisiae powder can reach 800～1100mg/kg, and wherein organic zinc content can reach more than 77%.
