Embodiment 1

[0019] Put 360Kg of food-grade corn lactic acid into the reactor, and carry out polymerization reaction at 90-120°C under vacuum for about 1.5 hours. Heat to 160-175°C and react for about 5 hours, measure the acid value to 150, lower the temperature to 80°C, then slowly add 430Kg of 30% by mass edible soda ash aqueous solution for neutralization to obtain sodium coconut oil acyl lactylate.

Embodiment 2

[0021] Put 282Kg of food-grade rice lactic acid into the reactor, carry out the polymerization reaction at 90-120°C under vacuum for about 2 hours, after measuring the acid value to 300, put in 250Kg of palm kernel oil fatty acid, and add 2.5Kg of catalyst sodium hydroxide at the same time, vacuum Heat it to 170-180°C and react for about 6 hours. After measuring the acid value to 140, lower the temperature to 80°C, and then slowly add 450Kg of 30% by mass edible soda ash aqueous solution for neutralization to obtain palm kernel oil acyl lactylate sodium.

Embodiment 3

[0023] Put 270Kg of food-grade corn lactic acid into the reactor, carry out polymerization reaction at 90-120°C under vacuum for about 1.0 hour, measure the acid value to 280, add 400Kg of lauric acid, and add 2.0Kg of catalyst sodium hydroxide at the same time, heat under vacuum React at 160-175°C for about 4 hours, measure the acid value to 160, lower the temperature to 80°C, then slowly add 300Kg of 30% by mass edible soda ash solution for neutralization to obtain sodium lauroyl lactylate.

Abstract

The present invention discloses a food-grade vegetable oil-based surfactant and a preparation method thereof, and belongs to the field of surfactants. Vegetable oil acyl sodium lactate is obtained by acylation polymerization, esterification, and neutralization reactions of vegetable raw material lactic acid, vegetable oil aliphatic acid and edible soda ash. The surfactant has a following structure: R-CO-[O-CHCH3-CO]nONa, wherein R-CO is a coconut oil fatty acid acyl group, a palm kernel oil fatty acid acyl group, a palm oil fatty acid acyl group, and a lauric acid acyl group. Each index reaches a food grade requirement. The surfactant is applied to a tableware detergent, is in line with the GB2760-2011 food additive hygiene standard, can replace a petroleum-based harmful product of sodium dodecylbenzenesulfonate, and can protect people's health.

Description

technical field [0001] The invention relates to a surfactant, in particular to a surfactant with food-grade requirements for tableware, food equipment, fruits and vegetables, and a preparation method thereof, belonging to the field of surfactants. [0002] area. Background technique [0003] The main component of the dishwashing liquid sold on the market is sodium dodecylbenzenesulfonate (LAS), which is a petrochemical component. When the substance accumulates in the human body to a certain level, it will endanger health. LAS is highly soluble in hemoglobin, which can easily cause changes in hemoglobin, cause anemia, impair human immunity, induce liver cell disease, liver and kidney function damage, and induce cancer; interfere with and damage sperm cells and egg cells, weaken and lose reproduction ability. [0004] In order to ensure food safety and protect people's health, it is of great practical significance to replace petroleum-based surfactants with vegetable oil-b...
