Description

Taurine-rich instant dietary fiber kudzu root sweet potato powder and preparation method thereof
Technical Field
The invention belongs to the field of food processing, and particularly relates to taurine-rich instant dietary fiber kudzu root sweet potato powder and a preparation method thereof.
Background
With the improvement of living standard of people, the single eating of a certain coarse cereal cannot meet the various demands of people on food. The dietary fiber obtained by processing the residual shells and skin residues of the coarse cereals is utilized, so that the effects of the coarse cereals on the lipid reduction and the intestinal health of a human body are better reflected.
The kudzu root and the sweet potato contain trace elements such as copper, cobalt, zinc and the like which are necessary for human bodies, and the skin residues after the kudzu root and the sweet potato are used contain rich dietary fibers, so that the kudzu root and the sweet potato has the effects of eliminating redundant cholesterol in the human bodies, preventing arteriosclerosis, losing weight, beautifying, reducing blood sugar, reducing blood fat and the like.
The marine organism is rich in protein, and has good edible value and medicinal value. The clam belongs to the phylum of mollusca, more than 30 kinds of clam are found, the nutrient substance is rich, the clam contains a plurality of trace elements necessary for human bodies, such as protein, vitamin, carbohydrate, calcium, magnesium, iron, zinc and the like, and the amino acid kind composition and the proportion thereof are reasonable, so the clam can be well absorbed and digested by the human bodies. The laver, belonging to the Rhodophyta, is rich in nutrition, delicious in taste, and rich in proteins, inorganic compounds, unsaturated fatty acids, vitamins and minerals, wherein the content of the proteins is as high as 25-50%, so that the laver has a wide prospect in the fields of food and medicine.
Taurine is a sulfur-containing amino acid with simple structure in animal bodies, is an essential amino acid for human body conditions, has important effect on the development of the nervous system of fetuses and infants, has the effects of resisting inflammation, relieving fever, easing pain, tranquilizing, reducing blood pressure, reducing blood sugar, resisting arrhythmia, resisting bacteria, resisting platelet aggregation, enhancing immunologic function, benefiting gallbladder, strengthening liver, detoxifying, regulating vascular tension and the like, is widely applied to the fields of medicines, food additives, fluorescent whitening agents, organic synthesis and the like, and can also be used as biochemical reagents, wetting agents, pH buffering agents and the like.
Most of the research and the manufacture of the brewing powder at the present stage are the utilization of single raw materials, so that the taste and the efficacy are very simple, and the requirements of people on the taste and the health can not be met. For example, the patent application "sweet potato starch production and potato residue treatment process" (application number: 200810031186.1) discloses a sweet potato starch process flow as follows: conveying, cleaning, disintegrating and separating pulp and slag, so far, the method is divided into two paths: one path is potato residue filter pressing, potato residue crushing, drying and potato residue packaging; the other path is filtering and separating the starch primary pulp, dehydrating the starch milk, drying the sweet potato starch, separating the gas and the powder, sieving, packaging the sweet potato starch and obtaining the finished product of the sweet potato starch. The patent application 'cellulose fruit and vegetable residue food rich in bifidus factors and a preparation method thereof' (application number: 02131223.0) discloses a preparation method of powdery or blocky food which is prepared by taking fresh fruit and vegetable residues with the water content of 15-40% as raw materials and carrying out cell wall breaking treatment on the fresh fruit and vegetable residues through steam explosion, after the cell wall is broken, cell contents are fully dissociated, hemicellulose of the cell wall is hydrolyzed into soluble dietary fibers, and the effective components of the fruit and vegetable residues are fully utilized. However, "fish eyes" are easily formed in the dissolving process of arrowroot and the like, namely, the outermost layer of the particles immediately absorbs water and expands to form a colloidal layer, and the inside of the particles is a large lump of a dry core, so that the transfer of water to the inner layer of the particles is delayed, the dispersity and the dissolving speed are reduced, the dissolving time is prolonged, the reconstituted viscosity cannot be completely released in a short time, and the raw materials cannot be thoroughly utilized by simple operation, so that the improvement needs to be further realized.

1) Taking 200g of fresh clams and 200g of laver, uniformly mixing and pulping, putting into water, wherein the mass ratio of the mixed solution of the clams and the laver to the water is 1:4, decocting in boiling water for 1h, filtering, placing the filtrate on one side, cooling for later use, and collecting precipitates;
2) taking 200g of fresh kudzuvine root peel residues and 200g of sweet potato peel residues, taking 200g of the precipitate obtained in the step 1), uniformly mixing and pulping;
3) adding 0.3% of amylase and 0.2% of compound protease according to the weight of the slurry in the step 2), performing enzymolysis for 60min at 35 ℃, and then inactivating the enzyme;
4) taking the slurry subjected to enzymolysis in the step 3), inoculating 0.01% of freeze-dried lactic acid bacteria powder and 0.01% of freeze-dried halomonas powder, and fermenting at the fermentation temperature of 23 ℃ for 3 days under the condition that the humidity of the fermentation environment is 85%;
5) mixing the supernatant prepared in the step 1) with the fermentation residues, cleaning for 40min in an ultrasonic cleaning machine, and carrying out vacuum freeze drying on the mixed slurry to finally obtain the instant powder.
The nutrient components and the quality of the taurine-rich instant dietary fiber kudzu root sweet potato powder prepared by the examples and the comparative examples are compared and shown in the table 1. The table shows that the whole fermentation process is an organically combined whole, the content of free taurine is greatly reduced, the content of soluble sugar is increased, the enzymolysis is not carried out, the fermentation process is not smooth, the content of active lactobacillus is reduced, and the problem possibly related to insufficient formation of a material structure protective layer is solved; comparative example 2 has not been fermented by lactic acid bacteria and halomonas, the functionality is single, the raw material utilization is not thorough, and the content of substances such as taurine is reduced. The comparative examples 1 and 2 show that the enzymolysis, the fermentation of the lactic acid bacteria and the halomonas can effectively release the functional substances of the raw materials, the structure of the raw materials is more favorable for adsorbing the functional substances, and the two materials with different properties are organically combined together, so that the flavor, the mouthfeel and the brewing property are greatly improved. Comparative example 3 shows that ultrasonic washing has an effect of enhancing the product quality, the content of functional substances of the sublimed product and the coordination of the flavor are further increased, and the product quality is reduced and the fusion is poor due to the absence of the step.
Comparing example 1 with comparative examples 4-7, it can be shown that from the multi-index evaluation of D value (number of lumps) and average particle size, viscosity and transparency, powder rehydration effect, etc., the synergistic fermentation of clam raw materials, lactic acid bacteria and halomonas, the addition of food grade zeolite powder, and the ultrasonic dispersion process significantly improve the instant solubility of the radix puerariae sweet potato powder, the clam raw materials and halomonas have the largest influence on the instant solubility, the zeolite and lactic acid bacteria have the same influence on the instant solubility, the influence on the instant solubility is slightly inferior, the ultrasonic dispersion influence is the smallest, and the promotion of instant dissolution by the fermentation of the clam raw materials and lactic acid bacteria is an unexpected effect.
