Problems solved by technology

However, this invention has three deficiencies: one is that the degree of esterification of sucrose polyester is not defined, such as sucrose esters with a degree of esterification of 3 to 5 are solid at normal temperature, and the use ratio is as high as 80 to 95%. It is difficult to make lubricating oil; second, there is no requirement for the quality standard of sucrose polyester, the main raw material of the product; third, the use of sulfur-containing additives does not control the hygienic quality indicators of lubricating oil products
Base oils that do not meet food hygiene requirements will endanger the quality and safety of lubricating oils, and the use of lubricating oils with sulfur-containing additives and heavy metal residues exceeding the standard will also lead to contamination of food and medicines

Abstract

The invention discloses a food-grade lubricant using sucrose polyester as base oil and a preparation method thereof. The food-grade lubricant is prepared from the following raw materials in parts by weight: 65-79 parts of sucrose polyester, 1-15 parts of hydrogenated tea seed oil, 0.1-15 parts of viscosity index improver, 0.01-4.0 parts of anticoagulant, 0.01-3.0 parts of antioxidant and 0.1-10.0 parts of extreme-pressure anti-wear agent. The preparation method comprises the following steps: premixing, dissolving, filtering and inspecting. The food-grade lubricant is prepared from the base oil sucrose polyester with the average esterification degree of 6-8 with other high-quality assistants; and the product has the advantages of oxidation resistance, high biodegradation rate, excellent lubricating property, high viscosity-temperature characteristics, high safety, high stability and the like.

Description

technical field [0001] The invention relates to a food-grade lubricating oil, in particular to a food-grade lubricating oil with average sucrose polyester as base oil and a preparation method thereof. Background technique [0002] Lubricating oil for food machinery is an important factor affecting food safety and an indispensable substance for food production. The contact between lubricating oil and food is inevitable in food production. Food-grade lubricating oil is relatively safe for food, while non-food lubricating oil contains some toxic ingredients, and its use will bring food safety hazards. At present, some domestic enterprises use animal oil and medical vaseline as lubricating oil for food machinery. Their safety is not high, and the quality of similar products in developed countries is still far behind. The food-grade lubricants used by export food companies and pharmaceutical companies are basically imported from abroad, which is controlled by others in terms of ...
