Abstract

The invention discloses soybean yoghourt pudding and a preparation method thereof. The method comprises the following steps of: 1) soaking, pulping and boiling soybean, adding unsalted butter, and mixing uniformly for homogenization to obtain soybean milk; 2) cooling the soybean milk obtained in the step 1), adding lactic acid bacteria, and fermenting at constant temperature to obtain curdy soybean yoghourt; 3) crushing, sterilizing and homogenizing the curdy soybean yoghourt obtained in the step 2) to obtain a soybean yoghourt homogenized solution; and 4) boiling a stabilizer, flavoring agents, sugar and water to obtain a colloidal liquid, cooling, and uniformly mixing the colloidal liquid and the soybean yoghourt solution obtained in the stop 3) to obtain the soybean yoghourt pudding. The lactic acid bacteria are used for fermentation to generate acid, acidity regulators are not added, and unique vitamin B of a fermented food is generated, so that the nutritional value of the soybean yoghourt pudding is higher than that of the common pudding on the market; and the lactic acid bacteria are killed through pasteurization, so that the product cannot be postacidified and is easy to store, the shelf life is prolonged and the quality of the product is stable.

Description

Bean yoghourt pudding and preparation method thereof
Technical field
The invention belongs to food processing field, be specifically related to a kind of bean yoghourt pudding and preparation method thereof.
Background technology
China's soybean yields comes the 4th, the world at present, soybean is the main vegetable protein food resource of China, its protein content is generally 35%~40%, fat content is 15%~20%, and wherein the necessary linoleic acid content of human body accounts for 50% of amount of total fat, and carbohydrate content is 20%~30%, content of mineral substances is 5%, more than nearly 13 kinds of vitamins, its kind, the height of content is that other wholefoods are incomparable.And contain necessary 8 seed amino acids of human body in soybean, its content basically with the United Nations health organization advise close.
Soybean protein does not contain cholesterol, and the effect that reduces Blood Cholesterol is arranged.Soybean contains cellulose, hemicellulose, and pectin, mannosan, bean gum, Soluble Fibers etc. have the effect of preventing tumor in digestive tract and other diseases.Soy oligosaccharide can promote Bifidobacterium amount reproduction in intestines, the effect that suppresses the spoilage organisms growth and reduce blood pressure.Lecithin in soybean can be removed the cholesterol that is deposited on blood vessel, also has isoflavones, glycoside, tocopherol, microorganism K, triglyceride, lectins etc.
Soybean comes from China, and its goods are loved by the people as the traditional food of China, but on present market, bean product pattern kind is single, and freshness date is too short, and packing falls behind, and food portable is poor, can not fully satisfy the demands of consumers.
Crystal diabetin has the advantages that sugariness is high, heat is low, do not cause that blood sugar raises, and can promote beneficial bacterium propagation in human body, improve functions of intestines and stomach and metabolism, the characteristics [4] that suppress carious tooth, promote the calcium absorption are arranged, and are all a kind of desirable sweeteners for diabetes patient, adiposis patient and children.
Lactobacillus-fermented can produce multiple organic acid, promotes intestines peristalsis, is beneficial to intestinal health.
Microbial fermentation has produced precious anti-oxidant, hypotensive isoreactivity material and the distinctive cobalamin that ferments when removing the own ANFs of soybean (trypsin inhibitor, haemoglutinin, Flatulent factors, the irritated factor, beany flavor).The lactic acid bacteria decomposing protein, fat waits macromolecular compound and produces some flavor substances.
Bean yoghourt is exactly a kind of sour milk product that utilizes the fermentation of microorganism to make, and it can bring into play the nutritive effect of soybean, can destroy again the ANFs in soybean, and soy proteinaceous digestibility is improved significantly.Bean yoghourt is with low cost, and unique flavor is nutritious, has good development prospect.
Having paper studies to mention a kind of fermentation pudding bean curd, is ferment and be aided with the GDL of traditional bean curd processing use and calcium chloride as coagulating agent by inoculating lactic acid bacterium in soya-bean milk, makes pure white delicacy and whippy bean curd.
On market, existing most of jelly puddings are all closely similar in formula, packing, production technology and taste mouthfeel, and unification is serious, can't reach good discrimination, are difficult to characteristic and the characteristics of outstanding each product.
The contained nutriment of jelly is few, is mostly to be formed by flavorant, pigment, polysaccharide gel, and the utilization that can not be absorbed by the body does not have good nutritive value.
Summary of the invention
The purpose of this invention is to provide a kind of bean yoghourt pudding and preparation method thereof.
The method for preparing the bean yoghourt pudding provided by the invention comprises the steps:
1) soybeans soaking pulled an oar and boil and obtain soya-bean milk, adding the whipping cream mixing to carry out homogeneous, obtaining soya-bean milk;
2) with described step 1) add lactic acid bacteria after the gained soya-bean milk is cooling, ferment at constant temperature obtains the curdy bean yoghourt;
3) with described step 2) fragmentation of gained curdy bean yoghourt, homogeneous after sterilization obtains the bean yoghourt homogenizing fluid;
4) obtain glue with boiling after stabilizing agent, flavorant, sugar and water, lower the temperature rear and described step 3) gained bean yoghourt homogenizing fluid mixing, obtain described bean yoghourt pudding.
Described step 1) in, the addition of described whipping cream is the 3-40% of soya-bean milk gross weight, preferred 10-15%; In homogenizing step, pressure is 5-50MPa, preferred 15-18MPa;
Described step 2) in, described direct putting type particle lactic acid bacteria is selected from least a in lactobacillus bulgaricus, streptococcus thermophilus and Bifidobacterium; The consumption of described lactic acid bacteria is the 0.1-5% of described soya-bean milk quality, preferred 1-1.5%; In cooling step, final temperature is 20-50 ℃, preferred 37-40 ℃; In described ferment at constant temperature step, temperature is 20-50 ℃, and preferred 38-40 ℃, the time is 2-10 hour, preferred 5-6 hour;
Described step 3) in described sterilisation step, method for disinfection is pasteurization; In homogenizing step, pressure is 5-50MPa, preferred 20-23MPa; In pasteurization, temperature is 50-80 ℃, and preferred 62-70 ℃, the time is 10-60 minute, preferred 20-50 minute;
Described step 4) in, described stabilizing agent is selected from least a in konjaku flour and carragheen; When described stabilizing agent was konjaku flour and carragheen, the mass ratio of described konjaku flour and described carragheen was 1-15: 1, and preferred 5-9: 1; When described stabilizing agent was konjaku flour and carragheen, the mass ratio of described konjaku flour and described carragheen was 1-15: 1, and preferred 5-9: 1; The mass ratio of described stabilizing agent, flavorant, sugar and water is 1-15: 50-150: 400, and preferred 5-10: 80-120: 400; Described glue and described step 3) mass ratio of gained bean yoghourt homogenizing fluid is 0.5-2: 1, preferred 4: 6; In described cooling step, final temperature is 60-95 ℃.
This bean yoghourt pudding has the following advantages compared with similar products: 1, this product bean yoghourt pudding utilizes lactobacillus-fermented to produce acid, does not add acidity regulator; 2, this product adopts zymotechnique, product is beneficial to digests and assimilates, and also produces the distinctive B family vitamin of fermented food, and nutritive value is higher than commercially available common pudding; 3, this product adopts pasteurize to kill lactic acid bacteria, makes the unlikely rear acidifying of product, is beneficial to storage, Shelf-life; 4, this product adopts direct putting type lactic acid bacteria, product with stable quality.
