Abstract
A purple sweet potato bean curd and a method for preparing the same. The raw materials of the purple sweet potato bean curd comprise 79.5 to 81.5 % of water, 13.5 to 14.5 % of soybeans, 4.5 to 6.5 % of purple sweet potato juice and 0.2 to 0.3 % of gluconic acid-delta-lactone. The method comprises heating soybean milk to 98 DEG C to 100 DEG C, uniformly mixing the soybean milk with the purple sweet potato juice after the soybean milk is cooled to 30 DEG C and then adding the gluconic acid-delta-lactone to get a mixture, heating and homogenizing the mixture under the pressure of 10 MPa to 15 MPa to get a homogeneous liquid, and disinfecting and then cooling and setting the homogeneous liquid to form the purple sweet potato bean curd. The purple sweet potato bean curd perfectly combines the efficacy of the bean curd and the purple sweet potato juice, and effectively improves nutrition and flavor of the bean curd.
Description
Technical field
The present invention relates to a kind of bean curd and preparation method thereof, particularly a kind of purple sweet potato bean curd and preparation method thereof.
Background technology
Soya bean has the laudatory title of " kings in the beans ", and the nutritive value of soya bean is the highest in the beans.The protein content of soya bean is nearly 40%, and is all higher than the protein content of any cereal crops.Contain various essential amino acids in the soya bean protein, approach human body proportion.Soya bean contains that grease is nearly 30%, and its unsaturated fatty acid content reaches more than 80%, and linoleic acid accounts for 55%.By goods such as the bean curd that soya bean processes, become the often edible food materials of people.
Bean curd originates from China, is the traditional food of being processed by soya bean of China, its original name " Li Qi ".Compendium of Material Medica is write: " method of bean curd starts from the Huainan king Liu An of the Early Han Dynasty ".The bean curd quality is fine and smooth, and soft tasty and refreshing, being of high nutritive value of it contains 8 seed amino acids of rich in protein and needed by human, protein digestibility 92% ~ 96%.For a long time, the bean curd kind that China produces is single, therefore is necessary existing bean curd is carried out the improvement of local flavor and nutrition.
Summary of the invention
The object of the invention provides a kind of local flavor and the improved purple sweet potato bean curd of nutrition and preparation method thereof.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of purple sweet potato bean curd, and the composition of raw materials of said purple sweet potato bean curd is made up of the material of following quality percentage composition:
Water 79.5-81.5%;
Soybean 13.5-14.5%;
Purple sweet potato juice 4.5-6.5%;
Glucono-0.2-0.3%.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of method of making purple sweet potato bean curd, comprise heating soybean milk to 98-100 ℃, and mix the back with purple sweet potato juice after being cooled to 30 ℃ and add glucono-and obtain mixed liquor; Be that homogeneous obtains homogenizing fluid under the condition of 10-15MPa at pressure with the heating of said mixed liquor, this homogenizing fluid cooling and shaping after sterilization steps obtains purple sweet potato bean curd.
Related content in the technique scheme is explained as follows:
1, in the such scheme, comprises defibrination after the soybean soaking is obtained soya-bean milk stoste.
2, in the such scheme, obtain said soya-bean milk with said soya-bean milk stoste centrifugation and through 80-100 purpose strainer filtering.
3, in the such scheme, with sterilizing again after the said homogenizing fluid packing.
4, in the such scheme, the condition of said sterilization is 85-88 ℃ and heated 30-35 minute down.
5, in the such scheme, the condition of said cooling and shaping is to adopt in the cooling water that is less than or equal to 25 ℃ in temperature to cool off 30-35 minute.
6, in the such scheme, purple sweet potato formal name used at school Assam sweet potato has another name called purple sweet potato.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
1, the present invention (is rich in protein, isoflavones, lecithin etc. with bean curd; Can effectively provide human body necessary amino acid; Improve the immunity of human body, increase the growing of brain and blood vessel, effects such as angiocardiopathy preventing) and purple sweet potato (be rich in anthocyanidin and selenium; Can effectively improve anticancer, arterial sclerosis, increase body immunity of human body etc.) effect carry out perfect adaptation, effectively increased the nutritive effect of bean curd.
2, the present invention makes the mouthfeel of purple sweet potato bean curd finer and smoother through homogeneous, and fragrance is more tempting, increases people's appetite.
