Abstract

The invention discloses a health tremella and semen cassiae dried bean curd. The health tremella and semen cassiae dried bean curd is prepared from the following raw materials in parts by weight: 200-210 parts of soybeans, 7-8 parts of tremella, 2-4 parts of coffee powder, 35-39 parts of black mulberry fruits, 3.5-3.8 parts of semen cassiae powder, 8-10 parts of fish sauce, 10-12 parts of sweet potato starch, 5-7 parts of kudzu vine root powder, 3-4 parts of butterflybush flower powder, proper amount of lactose, proper amount of citric acid and proper amount of lactic acid bacteria. The soaked soybeans are steamed, puffed and ground, so that the beany flavor can be removed, the water absorption rate can be increased, the soybean milk yield is increased and the yield is improved; the soybean milk is fermented to obtain a coagulating agent for coagulating, so that dangers caused by the fact that other chemical coagulating agents are added can be avoided, the quality of the dried bean curd can be improved and the nutritional value is increased. In a production process, the tremella and the semen cassiae are added, so that the dried bean curd has certain health effect and the diet pursuit of people are met.

Description

A kind of Tremella semen cassiae health-care dried tofu and preparation method thereof

Technical field

The present invention relates to food processing technology field, particularly relate to a kind of Tremella semen cassiae health-care dried tofu and preparation method thereof.

Background technology

Bean curd is invented in China, is increasingly becoming one of favorite bean product of south east asia resident.Bean curd is that Semen sojae atricolor is also contained water, carbohydrate and other component by flooding, the protein gel solidified with acid or salt.Its course of processing is broadly divided into two steps: the first step is by soybeans soaking, defibrination, mashing off, screenings isolated bean milk；Second step is to be boiled by bean milk and add coagulator so that it is solidification forms soybean curd, through suitably pressurizeing and discharging part Free water, i.e. obtains the bean curd (soy protein gel) with definite shape, hardness, elasticity and retentiveness.Bean curd is different due to its processing method, and product type is numerous.China is modal Glycine max (L.) Merr., bei-tofu, inner ester bean curd, processed bean curd, color bean curd, bittern tofu, tender bean curd etc..According to its processing characteristic, texture characteristic and water content, commercially available bean curd can be divided into again: hard bean curd, dried bean curd, soft bean curd and inner ester bean curd.

Dried tofu refers to that bean curd makes bean-curd product through dewatering process, is most representative bean-curd product on domestic market.Dried bean curd have the laudatory title of Vegetable meat, containing the nutrient substance of the needed by human such as rich in protein fat carbohydrate and calcium ferrophosphorus, has the advantage such as easily digested balanced in nutrition, all-ages.Owing to the dried tofu on market compares the most traditional in manufacturing process, it is all by defibrination direct after soybeans soaking, boils, add coagulator the most again and solidify, obtain through squeezing, the beany flavor of the dried tofu so obtained is bigger, and the residual of coagulator also can produce certain injury to people.Accordingly, it would be desirable to research and develop a kind of new technique to solve the problems referred to above.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of Tremella semen cassiae health-care dried tofu and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of Tremella semen cassiae health-care dried tofu, is made up of the raw material of following weight portion: Semen Glycines 200-210, Tremella 7-8, coffee powder 2-4, black Fructus Mori 35-39, Semen Cassiae powder 3.5-3.8, fish juice 8-10, sweet potato starch 10-12, powder of Radix Puerariae 5-7, Flos Buddlejae powder 3-4, lactose is appropriate, citric acid is appropriate, lactic acid bacteria is appropriate.

The preparation method of described a kind of Tremella semen cassiae health-care dried tofu, comprises the following steps:

(1) add after Semen Glycines being cleaned in the warm water of 23-25 DEG C and soak 6-8h, then the Semen Glycines soaked is placed on water proof in water-bath to cook, it is dried Semen Glycines after cooling after being 35-40% to water content to be sent into by Semen sojae atricolor in bulking machine again and carries out expanding treatment, carry out defibrination with sending into together after the warm water soaking 2-3h of 7-8 times 23-25 DEG C in fiberizer the most again, after filtration, obtain bean milk；

(2) wearing into slurry by after Tremella steep raising together with black Fructus Mori, put in water-bath and cook after then adding sweet potato starch, powder of Radix Puerariae mix homogeneously, dry after cooling, pulverizing obtains nutritive powder；

(3) appropriate lactobacillus inoculum is taken in the 15mL milk of sterilizing, 20-24h is activated at 35-37 DEG C, then take 1mL and inoculate in 15ml milk, activation 20-24h is continued at 35-37 DEG C, then the activated spawn obtained is accessed in the 100ml bean milk of sterilizing, under conditions of 35-37 DEG C, cultivate 24-28h, obtain lactic acid bacteria culture solution；

(4) bean milk that step (1) obtains is weighed the 15-20% of its weight portion, the supernatant is taken after centrifugal treating, the emulsion of lower floor is re-poured in remaining bean milk, then using citric acid to ferment the lactic acid bacteria culture solution that the pH regulator of the supernatant is the lactose and 6-7% that add its weight portion 1.5-2% after 5.5-6 to pH value of solution under conditions of temperature is 35-37 DEG C is 3.5-3.8, obtains bean milk coagulator；

(5) post-heating of remaining bean milk being mixed homogeneously with nutritive powder, coffee powder, Semen Cassiae powder, fish juice, Flos Buddlejae powder boil 15-20min after fast cooling to less than 10 DEG C, carry out heated and boiled 15-20min the most again, bean milk coagulator is added while the pH stirred to mixture is 5.0-5.2 when bean milk temperature naturally cools to about 80 DEG C, drainage after insulation 10-15min, obtains gel bean brain；

(6) being put into by gel bean brain and squeeze 40-50min in compacting tool set under pressure 3-5MPa, period keeps temperature 65-75 DEG C, treats to ooze out without moisture, obtain described Tremella semen cassiae health-care dried tofu.

The invention have the advantage that the present invention passes through the Semen Glycines expanded defibrination again after cooking that will soak, be possible not only to remove beany flavor, and water absorption rate can be increased, increase the pulping rate of Semen sojae atricolor, improve yield；It is possible not only to avoid adding the harm that other chemical coagulant produce by using bean milk itself to carry out fermenting to obtain coagulator to carry out solidifying, but also the quality of dried tofu can be improved, increase its nutritive value.The Tremella, the Semen Cassiae that add in manufacturing process make dried tofu have certain health-care effect, and the diet meeting people is pursued.

Detailed description of the invention
