A trans free non hydrogenated high C-16 type palm fat suitable for the manufacture of trans free non hydrogenated hard structural fat that is being suitable for use in the manufacture of low SAFA (Saturated Fatty Acid) poly / mono unsaturated margarine and spreads and shortening and fat blends incorporating such hard Structural fat. The Structural fat is made from selectively fractionated non-hydrogenated high melting palm oil fraction with a C-16 fatty acid residue of at least 70%, which is subjected to chemical random interesterification using alkaline metal catalyst such as sodium methoxide / sodium methylate, with a dry fractionated non hydrogenated hard palm kernel stearin fraction. The structural fat that is produced has high yield ratios that can be economically and commercially incorporated in the oil blends for the manufacture of trans free margarine / spreads / shortening as well as other plastic W / O emulsions. Also described is a process for the manufacturing such structural fat as well as hard palm fraction including process for the manufacture of extra hard trans free structural fat by panning and pressing of above structural fat.

The invention relates to a method for preparing low / zero trans-fatty acid plastic grease from camphor tree seed oil. The method comprises the following steps of: putting refined camphor tree seed oil and palm oil stearin or fully-hydrogenated soybean oil serving as raw materials into a temperature-controlled reaction kettle, and uniformly mixing the palm oil stearin or the fully-hydrogenated soybean oil with the camphor tree seed oil in the mass ratio (3-6):(4-1) for 1-3 hours; after mixing, adding 5-15 percent of preferred Lipozyme RM IM lipase or TL IM lipase, and reacting at the temperature 55-75 DEG C for 6-12 hours, wherein the optimal temperature is 55-75 DEG C; after reacting, standing for 1-5 hours and filtering the lipase; and deacidifying with 0.05-0.5 N of sodium hydroxide solution and drying in vacuum for 12-24 hours to obtain a finished product. According to the method, low / zero trans-fatty acid plastic grease (including base oil such as margarine, shortening and the like) of different melting points and solid fat contents can be prepared.

An amylose preparation method is to mix the natural starch which particle size is 1-9 mu m, starch debranching enzyme solution which weight content is from 1% to 10%, and plasticizer component together, then continuously react and extrude from the screw-type reactive equipment under pH of 4.0-6.5 and temperature of 40deg.C-105deg.C. The ratio of different materials is 40-70 weight share of natural starch, 30-60 weight share of enzyme solution, 2-10 weight share of plasticizer component. Among them, the plasticizer component includes at least one of polyalcohol mixture containing alcohols glycerin, glycol, butanediol, sorbitol, xylitol, or any one of acid amides containing formamide, caprolactam, or any one of carbamide and stearin.

A process for the production of a composition comprising 1,3-dioleoyl-2-palmitoyl glyceride (OPO) comprises: providing one or more palm oil stearin fractions comprising tripalmitoyl glyceride and having an iodine value between about 18 and about 40; interesterifying the one or more palm oil stearin fractions to form a randomly interesterified palm oil stearin; subjecting the randomly interesterified palm oil stearin to enzymic transesterification with oleic acid or a non-glyceride ester thereof using an enzyme having selectivity for the 1- and 3-positions of a glyceride; and separating palmitic acid or palmitic non-glyceride esters from the product obtained in (iii) to form a composition comprising OPO glyceride.

The invention discloses a qiupu crab cream meat bun and a preparation method thereof. The qiupu crab cream meat bun is mainly prepared by mixing raw materials including flour, crab cream, qiupu flower salmon meat, side pork, pigskin jelly, farm egg, lard stearin, agaric, Chinese parsley, chopped green onion, bruised ginger, white sugar, yellow wine, sweet potato starch, sesame oil, spiced vinegar, soy sauce, refined salt, ground pepper, cheese, red-yolk salted duck egg yolk and gourmet powder according to certain parts by weight. The qiupu crab cream meat bun disclosed by the invention is unique in the formula of stuffing, is delicate and delicious in meat quality due to the qiupu flower salmon meat, is unique in mouth feel since the qiupu flower salmon meat is added into the stuffing of the qiupu crab cream meat bun, and is higher in dietary fiber and vitamins simultaneously due to the Chinese parsley; and the fat, the vitamins and the cellulose are evenly matched with one another, so that the qiupu crab cream meat bun is good in mouth feel and abundant in nutrition, thereby being edible for the man, the woman, the young and the old.

The invention belongs to the chemical field and relates to a multifunctional assistant for plastic processing and a preparation method of the multifunctional assistant.
