The prepared soap has a strong detergent effect, imparts a pleasant fragrance to a washed item, and re-utilizes waste oil.

Description

 Method for preparing soap by using metamorphic edible oil

 Technical field

 [0001] The present invention relates to a method for comprehensive utilization of waste, and in particular to a method for preparing soap using a deteriorated edible oil.

 Background technique

 [0002] During the storage of edible oil, triglycerides in oil are decomposed into glycerol and fatty acids under the action of light, heat and bacteria, and the latter can be further oxidized into peroxides, ketones, aldehydes, etc. A mixture of various substances has a "hala" taste. The formation of toxic substances has a stimulating effect on the gastrointestinal tract, and can also cause damage to the nervous system and liver.

 [0003] The preparation method of soap is generally after deodorization and deacidification treatment, adding sodium hydroxide solution, stirring constantly, after esterification, adding antioxidant, preservative and flavor, etc., stirring evenly, pouring into the mold After cooling, demould, shape, print the icon, put it in the dry room and dry it for a while.

 technical problem

 [0004] The technical problem to be solved by the present invention is to provide a new method for preparing soap with metamorphic edible oil with reasonable design and reasonable operability for the deficiencies of the prior art.

 Problem solution

 Technical solution

 [0004] The technical problem to be solved by the present invention is achieved by the following technical solutions. The invention relates to a method for preparing soap by using metamorphic edible oil, which is characterized in that: all raw materials are edible oils having a shelf life, and are saponified, shaped and dried according to a certain formula; the formula is: to every 1000 ml In the shelf life edible oil, 450-550 ml of water, 450-550 g of sodium hydroxide, 15-25 g of salt, and 15-25 g of flavor are added; the saponification temperature is 80 ° C, and the saponification time is 35-45 minutes; The drying temperature is 55 65 ° C, and the drying time is 48 8 吋.

The technical problem to be solved by the present invention can also be achieved by the following technical solutions. The method for preparing soap by using the modified edible oil is characterized in that: the formula is to add 500 ml of water, 500 g of sodium hydroxide, 20 g of salt, and 20 g of flavor to each 1000 ml of shelf life edible oil. [0007] The technical problem to be solved by the present invention can also be achieved by the following technical solutions. The above method for preparing soap by using a deteriorated edible oil is characterized in that the saponification temperature is 80 ° C and the saponification time is 40 minutes.

 [0008] The technical problem to be solved by the present invention can also be achieved by the following technical solutions. The above method for preparing soap by using the deteriorated edible oil is characterized in that: the drying temperature is 60 ° C, and the drying time is 6 hours.

 Advantageous effects of the invention
