The invention discloses a preparation method of propylene glycol monosaturated fatty acid ester with a pH buffering function, which comprises the following steps: uniformly mixing liquid saturated fatty acid with propylene glycol, then adding a compound catalyst, reacting at 110-180 DEG C for 3-8 hours, and after the reaction reaches the end point, dehydrating to obtain the propylene glycol monosaturated fatty acid ester, the compound catalyst is a mixed aqueous solution of inorganic acid and hydroxide. According to the method, saturated fatty acid and propylene glycol are taken as main raw materials, a compound catalyst is added, and high-efficiency esterification synthesis is realized under certain reaction conditions. The prepared propylene glycol monosaturated fatty acid ester is good in color and luster, not only has good emulsifying performance, but also has an excellent pH buffering function, can maintain the stability of a system when an acid-base environment changes, and widens the application range of the propylene glycol monosaturated fatty acid ester in the fields of foods, cosmetics, medicines and the like. The method is simple in process, high in reaction efficiency, good in product chromaticity and environmentally friendly.

In frozen foods that use emulsified sauces, ice crystals form during freezing storage, and starch retrogradation occurs due to freezing, which destroys the emulsion in the sauce, causing water and oil separation and a loss of flavor when thawed. [Solution] An emulsified sauce is prepared using an oil and fat composition for emulsified sauce, which is characterized in that the edible oil and fat contains a polyhydric alcohol unsaturated fatty acid ester having an HLB of less than 12 and an average esterification rate of 10% or more.

This application relates to the fields of daily chemical and fine chemical industries, specifically to microcapsule carriers and their preparation methods, microcapsule compositions, and applications. The microcapsule carrier of this application comprises hydroxyl saturated fatty acid esters, polysaccharide polymers, surfactants, and water; the weight ratio of hydroxyl saturated fatty acid esters, polysaccharide polymers, and surfactants is (1-10):(0.1-1):(5-60). It forms a three-dimensional network structure through the composite of hydroxyl fatty acid esters, polysaccharides, and surfactants, resulting in a yield stress ≥0.5 Pa and exhibiting significant shear-thinning rheological behavior, ensuring stable suspension of the microcapsules during storage and use.

The present invention relates to a novel resin composition containing poly(3-hydroxybutyrate) (also referred to as "PHB") and a crystallization nucleating agent, the resin composition being capable of suppressing the occurrence of burrs and warpage during injection molding. The resin composition contains PHB, a polyglycerol unsaturated fatty acid ester, and a crystallization nucleating agent.

Provided is a curing-type organic urethane binder with which it is possible to advantageously produce a casting mold exhibiting excellent casting mold properties, while reducing influences on the environment as compared with conventional ones.　The curing-type organic urethane binder is for use in producing urethane-based casting molds and is composed of two liquids, an A liquid comprising a polyol compound as a main component and a B liquid comprising a polyisocyanate compound as a main component. The A liquid includes (a) a saturated fatty acid ester having a boiling point of 110-300°C and having a structure represented by structural formula (1) and (b) a C6-C20 aliphatic hydrocarbon, as a solvent. (In the formula (1), R1 is a C1-C12 hydrocarbon group and R2 is a C1-C10 hydrocarbon group.)
