Description

Thin and uniform skin health preserving soybean hull production process
Technical Field
The invention relates to the technical field of food processing, in particular to a preparation process of health-preserving soybean hulls with thin and uniform hulls.
Background
The bean curd skin and bean processing byproducts are generally supplied at breakfast stalls at the street, the street and the tail, and are also supplied at noon or at night in special restaurants or old-size restaurants, the bean curd skin contains rich high-quality protein and high nutritional value, contains a large amount of lecithin, prevents angiosclerosis, prevents cardiovascular diseases, protects the heart, contains various mineral substances, supplements calcium, prevents osteoporosis caused by calcium deficiency, promotes bone development, is extremely beneficial to the bone growth of children and the old, and is suitable for being eaten by weak people, malnutrition, deficiency of both qi and blood and the elderly with thin and thin people; the special-flavor tofu skin is suitable for people with hyperlipidemia, high cholesterol, obesity and angiosclerosis, tofu skin is a famous dish and is a dish line and staple food which is necessary on a table, flavor tofu skin or cured meat boiled tofu skin or fried tofu skin on the table is a delicious food developed and developed in the history of tofu skin for hundreds of years, the delicious food of tofu skin has a history of hundreds of years, a plurality of village grandparents all make tofu skin, and the tofu skin has various eating ways. Can be cooked or steamed, and can be used as staple food or adjuvant. The method comprises the steps of preparing kang bean curd skin, steaming the bean curd skin and frying the bean curd skin; the preserved meat boiled beancurd skin has three fresh beancurd skins, various patterns and complete varieties. Most surprisingly, the skin of beancurd can be optionally matched with other food materials. Mixing with green vegetables, and eating fresh and tasty; when the meat is matched with the meat, the meat cannot feel greasy, meat and fishy when eaten.
The skin of beancurd is thicker in the preparation process at present, and the thickness of skin of beancurd is inhomogeneous, can not realize improving through the preparation technology to the skin of beancurd, the thickness that makes the skin of beancurd can make is thinner, can't reach the mode through adopting the scraper blade to spread the thick liquid, the thickness that makes the skin of beancurd makes more even purpose, current skin of beancurd taste is relatively poor simultaneously, can not realize through adopting high-quality rice and being equipped with beans, maize and millet auxiliary material are makeed, promote the taste of skin of beancurd, thereby give the unfavorable of popularization ten minutes of skin of beancurd.
Disclosure of Invention
Technical problem to be solved
Aiming at the defects of the prior art, the invention provides a health-preserving tofu skin making process with thin and uniform skin, and solves the problems that the thickness of the tofu skin can be made thinner due to the fact that the existing tofu skin is thick and uneven in thickness in the making process, the making process of the tofu skin cannot be improved, the thickness of the tofu skin cannot be made more uniform due to the fact that the existing tofu skin is made thick by adopting a scraper to spread slurry, and the taste of the tofu skin cannot be improved due to the fact that high-quality rice is matched with bean, corn and millet auxiliary materials to make the tofu skin is poor.
(II) technical scheme
In order to achieve the purpose, the invention is realized by the following technical scheme: a manufacturing process of health preserving soybean hulls with thin and uniform hulls specifically comprises the following steps:
s1, selecting high-quality rice: respectively selecting early rice, late rice, high-quality rice and glutinous rice, weighing and proportioning the early rice, the late rice and the high-quality rice, manually screening mung beans, soybeans, peas, millet, buckwheat, corns and sorghum rice, and then respectively weighing garlic, ginger and lotus root starch in required weight parts;
s2, soaking rice and coarse cereals: soaking the early rice, the late rice, the high-quality rice, the mung bean, the soybean, the corn, the sorghum and the millet selected in the step S1 in clear water at a certain temperature for a corresponding time, wherein the soaking time has an important influence on the thickness of rice milk ground by a stone mill and a finished product, and the type of the rice and the proportion of various coarse cereals added have strict requirements and influence the taste more or less;
s3, grinding: grinding the early rice, the late rice, the high-quality rice, the mung bean, the soybean, the corn, the sorghum and the millet which are soaked in the step S2 into pulp by adopting a stone mill turntable at a certain grinding disc gap interval, and grinding the soaked early rice, late rice, high-quality rice, mung bean, soybean, corn, sorghum and millet to be fine and smooth;
s4, ironing the beancurd sheets: placing a spoon, taking a certain volume of ground pulp, pouring the ground pulp on the surface of a pot, uniformly plastering rice pulp in the pot by a fan-shaped shell or a scraper, directly determining the thickness of a bean curd skin cake shape by the amount of the rice pulp taken from the spoon, wherein the thickness can directly relate to the temperature duration, the maturity and the taste in a stove, then continuously and uniformly heating with medium fire, easily pasting the bean curd skin when the fire is too large, smoothly taking the whole bean curd skin out of the pot when the fire is too small, and influencing the bean curd skin forming and the maturity after being scalded by strong fire with small fire;
s5, taking out of the pot, cooling and cooling: the beancurd skin which is baked in the step S4 is placed on a bamboo rack or a net in a round cake shape for cooling, the requirement on the current climate temperature is very high, the storage time is short if the temperature is too cold, the natural cooling time is long if the temperature is too high, the beancurd skin which is baked in the step S4 becomes hard and is not sticky when the beancurd skin is cooled, and the optimal state is realized;

Processing enterprises at a certain time respectively prepare three groups of bean curd skins by adopting the preparation method of the embodiment 1-3 of the invention, the three groups of bean curd skins are respectively marked as an A group, a B group and a C group, the bean curd skins of the same type in the market are selected and marked as a D group, then the thicknesses of the four groups of bean curd skins of the A group, the B group, the C group and the D group are respectively detected by measuring equipment, the maximum thickness values are respectively recorded, the average thickness value is calculated, the four groups of bean curd skins are cooked, the taste evaluation is reduced, and the experimental results are shown in table 1.
Table 1 comparative experimental data table
Figure BDA0003624000630000101
As can be seen from Table 1, the thickness of the three groups of skins produced by the manufacturing process of examples 1 to 3 of the present invention is significantly thinner than that of the skins on the market, the mouthfeel is better, and the thickness of the soybean hull prepared by the preparation process of the embodiment 1 is the thinnest, so the embodiment 1 is the best proposal, therefore, the invention can realize that the thickness of the tofu skin can be made thinner by improving the making process of the tofu skin, well achieves the aim of making the thickness of the tofu skin more uniform by adopting the mode of smearing the soybean milk by the scraping plate, meanwhile, the bean curd skin is made by adopting high-quality rice and being matched with auxiliary materials of beans, corns and millet, so that the taste of the bean curd skin is improved, the tofu skin prepared by the invention is delicious in taste, rich in nutrition, good in cooking, high in nutrition value, and good in health preservation, and is beneficial to the health of eaters, so that the tofu skin is beneficial to popularization.
And those not described in detail in this specification are well within the skill of those in the art.
