Embodiment Construction

[0008] The present invention adopts the active nickel obtained by reducing nickel salt through sodium borohydride as the main body of the camellia oil hydrogenation catalyst. This active nickel is stabilized by a water-soluble polymer in an aqueous solution to form a water-soluble polymer-nickel catalyst, and the nickel salt can be nickel sulfate, nickel chloride, nickel carbonate, nickel acetate, or can be A kind of nickel salt, also can be their mixture or organic complex, said water-soluble polymer can be polyvinyl alcohol, polyvinyl pyrrolidone (PVP for short) and their derivatives, wherein PVP is the best , and PVP with various degrees of polymerization can be used, and its molecular weight is 1000-360000. The role of water-soluble macromolecular polymers is described below with PVP as the representative:

[0009] The carbon chain of PVP can not only prevent the aggregation of active nickel, but also prevent the diffusion of triglycerides in tea oil to active nickel (cata...

Abstract

The invention discloses a method for producing cocoa butter substitutes by using tea oil as a raw material. The method comprises the following steps: firstly, selectively performing hydrogenation hardening on the tea oil through a water-soluble macromoleclar polymer and nickel catalyst; then carrying out extraction by using a solvent; extracting cocoa butter similar products from hardened oil through a fractional crystallization method; secondly, converting the other parts of the hardened oil subjected to hydrogenation into esterified oil by utilizing sodium methoxide as a catalyst; then carrying out washing and fractional crystallization to obtain the cocoa butter substitutes. The cocoa butter substitutes produced by utilizing the method can be used as raw materials for producing chocolates or coatings of some desserts in the food industry, and can also be used as matrix or additives of some suppository, ointments or cosmetics in the pharmaceutical industry and daily-use cosmetics industry.

Description

technical field [0001] The invention belongs to oleochemical technology, and relates to a method for preparing cocoa butter substitute by using camellia oil as a raw material. Background technique [0002] As we all know, cocoa butter is a kind of precious edible oil, which is extracted from cocoa beans, cocoa endosperm or cocoa pulp. In addition, cocoa butter can also be used in the pharmaceutical industry and the daily cosmetic industry. In the international market, the price of cocoa butter is 5-10 times higher than that of general oils. Due to market considerations, people have long been engaged in research and development of cheap cocoa butter substitutes. [0003] Cocoa Butter (CBE for short): It has a similar chemical structure and physicochemical properties to cocoa butter, can be completely mixed with cocoa butter, and can completely replace cocoa butter, such as Burneo tallow, Shea Butter And Mowrah fat and so on. But the natural resources of these oils are ver...
