Abstract

The invention belongs to the technical field of soap preparation and relates to a preparation method of pea starch-based transparent soap, which comprises the steps of firstly taking 19-20 parts by weight of pea starch and 80-90 parts by weight of water to prepare transparent starch milk, cooling the starch milk to 70-80 ℃, adding 10-15 parts of coconut oil, 15-20 parts of beef tallow and 10-20 parts of sodium hydroxide, stirring at constant temperature for 4-6 hours to complete emulsification, adding 5-10 parts of glycerol, 5-10 parts of rock sugar and 4-6 parts of propolis to prepare uniformly, injecting into a mould to freeze and mold, demoulding, finally placing soap blocks in a ventilation environment with 25 ℃ and humidity of 40% to cool soap, controlling the water loss rate to be about 1.15%/day, and drying to about 12% of total water loss rate to obtain a finished product. The invention utilizes the characteristic of high amylose content of pea starch to construct a stable starch oil gel system, and solves the problems of insufficient transparency, poor elasticity and poor stability of the existing starch-based transparent soap.

Description

Preparation method of pea starch-based transparent perfumed soap Technical Field The invention belongs to the technical field of soap preparation, and relates to a preparation method of pea starch-based transparent soap. Background The transparent soap has the advantages of rich color, easy modeling, dense foam, low skin irritation and the like, has excellent comprehensive cleaning power, can clean skin without excessively peeling natural sebum of the skin, can be added with various moisturizing components, and becomes a high-grade cleaning product which is deeply favored by consumers. Along with the improvement of consumer demands for natural, mild and high-quality daily chemical products, the development of transparent perfumed soap based on natural raw materials becomes an industry development trend. The starch is used as a natural renewable raw material and is widely applied to the fields of daily chemicals, foods, medicines and the like. At present, part of starch-based transparent perfumed soap is available on the market, but cereal starch or potato starch is mostly adopted as raw materials, and the problems of insufficient transparency, poor elasticity, poor structural stability and the like of the product exist. The main reason is that the amylose content of cereal starch and potato starch is low, and the system formed after gelatinization is difficult to combine transparency and stability, so that the high-grade development of the product is limited. The pea starch is used as a main component of peas, the content of the pea starch is up to 50%, and the pea starch has the natural advantages of white appearance and fine texture. Compared with the traditional cereal starch and potato starch, the pea starch has obviously higher amylose content, can form a system with high transparency and good elasticity after gelatinization, and provides an ideal raw material basis for preparing high-quality transparent perfumed soap. However, there is no related technical solution for preparing transparent soap by constructing a stable starch oleogel system by utilizing the characteristic of pea starch, so that development of a preparation method of transparent soap based on pea starch is needed to make up for the defects of the prior art. Disclosure of Invention The invention aims to solve the problems and provide a preparation method of pea starch-based transparent perfumed soap. In order to achieve the aim, the invention provides a preparation method of pea starch-based transparent perfumed soap, which comprises the steps of S1, preparing starch milk, namely taking 19-20 parts of pea starch and 80-90 parts of water according to parts by weight, uniformly stirring with cold water, heating, and continuously stirring until the system is transparent to obtain pea starch milk; S2, emulsifying, namely cooling pea starch milk to 70-80 ℃, adding 10-15 parts of coconut oil, 15-20 parts of beef tallow and 10-20 parts of sodium hydroxide, and keeping the temperature for stirring for 4-6 hours until emulsification is complete to obtain emulsified soap liquid; S3, blending and molding, namely stirring the emulsified soap solution, adding glycerol, adding 5-10 parts of rock sugar and 4-6 parts of propolis, uniformly stirring, injecting into a mold, freezing, cooling, molding and demolding; S4, cooling soap, namely cutting uneven soap blocks, cutting the uneven soap blocks into preset thickness, drying the soap blocks in a drying chamber with the temperature of 25 ℃ and the humidity of 40% and good ventilation, controlling the water loss rate to be 1.15%/day, and drying the soap blocks until the total water loss rate is 12%, thus obtaining the pea starch-based transparent soap. Further, the heating temperature in the step S1 is 90-100 ℃, and the stirring speed is 150-200r/min. Further, in the step S2, the stirring speed is 200-250r/min. Further, in the step S3, the glycerol is added in an amount of 5-8 parts, the freezing and cooling temperature is 0-5 ℃, and the cooling time is 4-6 hours. Further, the preset thickness of the soap block in the step S4 is 1.5-2cm. The beneficial effects of the invention are as follows: The invention selects pea starch as a core raw material, utilizes the advantages of high amylose content and fine texture, forms a stable starch oil gel system with grease through emulsification after gelatinization, has obviously better transparency than the traditional cereal starch and potato starch-based system after gelatinization and cooling, and the prepared soap has high transparency and good elasticity, thereby solving the technical pain of insufficient transparency of the traditional starch-based transparent soap. The invention ensures stable formation of the system by precisely controlling the process parameters of each step, especially the heating and stirring conditions, the emulsification temperature and time, the temperature and humidity and the water loss rate in the soap cooling process, compact pr
