[0030] 2. Preparation of soap base of sturgeon testis oil soap products

[0031] Mix 20-50ml of sturgeon gonad oil with the same volume of ethanol, heat up to 50°C-90°C, weigh 10-30ml of 30wt% sodium hydroxide solution (cooled to a temperature similar to that of the oil) and slowly pour it into the oil and mix evenly; Stir continuously at a temperature of 50°C-90°C for 2-4h, and the saponification process ends.

[0032] 3. Soap base into the mold

[0033] Pour the above soap base into the mold, put it in an oven at 20°C-40°C to keep warm, take it out after 2-4 days until the soap liquid solidifies, and put it in a cool and dry place for 30-50 days.

[0034] 4. Grinding of soap base

[0035] Grind the above-mentioned soap base into mud and set aside.

[0036] 5. Blending of soap color and smell

[0037] a. Take the orange peel / lemon for ultrasonic treatment and crush it to get the filtrate and mix it into soap mud (adding 1-3wt% by weight percentage of soap mud), so as to g...

[0044] 1. Preparation of oil from the male gonad of sturgeon (sturgeon testis)

[0045] After the male gonad of sturgeon is minced, weigh 60g of the minced raw material and mix it with 2 times the quality of water;

[0046] Add neutral protease at an enzyme dosage of 3000U / g, enzymatic hydrolysis with water for 4 hours, hydrolysis temperature at 50°C, and pH 7.0; during the reaction process, adjust the pH with a pH meter every half hour to maintain a stable pH at 7.0;

[0047] Inactivate the enzyme in a boiling water bath for 10 minutes, centrifuge at a centrifugal force of 3000×g for 10 minutes to separate the layers, collect the upper layer of oil, add sodium hydroxide to the oil for refining, and obtain the gonad oil of sturgeon.

Abstract

The invention relates to a soap making method, and concretely relates to a method for making a soap product by using sturgeon gonad grease. The making method comprises the following steps: extracting the sturgeon gonad grease, preparing a soap base, placing the soap base in a die, storing a cold made soap, grinding the soap base, matching to adjust the color and the smell of the soap base, and placing the obtained soap base in the die. The handmade soap is made by using the sturgeon gonad grease for the first time, and is different from soap products obtained by using plant grease, lard and other animal greases; the grease content of sturgeon gonad is high, the main grease component of the sturgeon gonad is neutral grease benefiting soap making, and the content of proteins and phosphatides in the sturgeon gonad is small, so a raw material preprocessing process is simple and easy; and the proportion of C14-C18 fatty acids (comprising oleic acid) is large, and the sturgeon gonad also contains EPA and DHA with special physiologic activity, so the soap made in the invention is better than the soaps adopting other greases in state and composition components.

Description

technical field [0001] The invention relates to a method for making soap, more specifically, relates to a method for preparing soap products from gonad oil of sturgeon. Background technique [0002] Sturgeon is one of the most primitive and oldest fish species on earth, and it is also the largest and longest-lived fish among freshwater fishes, known as "living fossil in water". The whole body of sturgeon is a treasure, and caviar is the first target product of sturgeon processing, while the gonads of sturgeon as a "by-product" of sturgeon processing have not been fully utilized. It has been reported that the gonad oil content of sturgeon is more than 70%, so the effective use of gonad oil of sturgeon can fundamentally solve the problem of how to efficiently use the gonad of sturgeon. [0003] Soap is the oldest washing product used by human beings. Fatty acid salts obtained by saponification or neutralization reaction of grease, wax, rosin or fatty acids with alkalis can al...
