The invention discloses a preparation process for a high-fat dark brown sugar preserved plum candy, which comprises six steps, i.e. preserved plum pretreatment, sugar melting, emulsification, boiling, pouring formation and selection. Complex emulsifying agent is used at the stage of emulsification and consists of sucrose fatty acid esters S770, sucrose fatty acid esters S570 and soy bean lecithin according to a mass ratio being 3:2:5. Two steps of emulsification processes are adopted. The used amount of the complex emulsifying agent is 0.5-1 percent of the mass of sugar liquid to be blended. The preparation process can effectively solve the problem of emulsification difficulties in the production of high-milt-fat dark brown sugar candies, and can also effectively solve the problems that a great number of air bubbles are produced and the material viscosity is reduced because of the air bubbles. The process is used for the preparation of the high-milt-fat dark brown sugar preserved plum candy and can effectively guarantee the quality and the attractiveness of the finished candies.

The invention belongs to the field of metal cutting fluids, and discloses a novel-emulsion-system cutting fluid based on a polyisobutylene succinic anhydride and a preparation method and application of the cutting fluid. The cutting fluid comprises base oil, a polyisobutylene succinic anhydride mixture (the mixture is formed by mixing of three polyisobutylene succinic anhydrides which separately have a molecular weight of 200, 400 and 1000, and the mass ratio of the polyisobutylene succinic anhydride with a molecular weight of 200 to the polyisobutylene succinic anhydride with a molecular weight of 400 to the polyisobutylene succinic anhydride with a molecular weight of 1000 is 2:1:1), a non-ionic surfactant, a pH modifier, a lubricant, an extreme pressure agent, an antirusting agent, a corrosion inhibitor, and a bactericide. According to the invention, the polyisobutylene succinic anhydride mixture is used as a main emulsifier of the cutting fluid for the first time, thus the emulsion system is very stable, stinking and bacterium growth are not easily, and the product service life is very long, wherein the cutting fluid can be used for half a year or more; and the cutting fluid has properties such as excellent antirust properties, lubricating performance and low-foam performance. The cutting fluid properties are excellent, thus the cutting fluid can be used in machining center with high speed precision, especially the cutting fluid has outstanding performance in a non-ferrous metal processing aspect, and the cutting fluid is mainly used for aspects such as electronic product tapping, and deep-hole drilling.
