Problems solved by technology

However, as we all know, when unsaturated fatty acids are exposed to the air, they are easily affected by external factors such as air, water, and sunlight in the environment, and undergo oxidation-reduction reactions, resulting in oxidative rancidity of oils and destroying the original nutrients and flavor substances in the oil. , which seriously affects the quality of oil

Embodiment 1

[0024] The preparation method of pine nut oil microcapsules comprises the following steps:

[0025] 1. Preparation of aqueous phase solution: Dissolve maltodextrin in water and mix evenly to form wall material phase solution. Among them, maltodextrin accounts for 60% of the total raw material quality. Dissolve sucrose ester in water, add wall material phase solution, and mix well. Among them, sucrose ester accounts for 3.5% of the total raw material mass.

[0026] 2. Preparation of oil phase solution: Dissolve monoglyceride in pine nut oil and mix evenly to form a composite emulsifier core material phase solution. Among them, monoglyceride accounts for 1.5% of the total raw material quality, and pine nut oil accounts for 35% of the total raw material quality.

[0027] 3. High-speed mixing: Mix the oil phase solution obtained in step 2 with the water phase solution obtained in step 1, and stir at 60°C for 20 minutes. The obtained mixed solution was first emulsified by a hig...

Abstract

The invention provides a pine nut oil microcapsule and a preparation method thereof, belongs to the technical field of processing of functional oil and fat products, and aims to solve the conventional problems of pine nut in food application. The microcapsule is prepared from raw materials as follows: 50%-65% of maltodextrin, 3.5%-4.5% of sucrose ester, 0.5%-1.5% of glycerol monostearate and 30%-45% of pine nut oil. The preparation method comprises steps of preparation of an aqueous phase solution, preparation of an oil phase solution, high-speed mixing, homogenizing, spray drying and the like. The method is simple in process, the source of raw materials is wide, carbohydrate is taken as the main wall material, both entering of oxygen and overflow of off flavor of grease are inhibited after microcapsule formation, the functional active ingredients of the pine nut oil are kept greatly, the oxidation stability of the pine nut oil is improved, and bad flavor of the pine nut oil is covered up.

Description

technical field [0001] The invention belongs to the technical field of processing functional oil products, and relates to a pine nut oil microcapsule and a preparation method thereof. Background technique [0002] Pine nut is the seed kernel of the famous and precious tree species Korean pine, which is mainly distributed in Northeast my country. Pine nuts are rich in protein, carbohydrates, fat, and trace elements such as calcium, phosphorus, and iron. Most of its fat is unsaturated fatty acids such as oleic acid and linoleic acid. Unsaturated fatty acids have a good effect on promoting the development of brain cells. Eating healthy people can reduce diseases and enhance physical fitness. Pine nuts are often regarded as the first choice for mental health. The oil content of pine nuts is extremely high, reaching more than 65%, and unsaturated fatty acids account for about 90%. Among them, linoleic acid has the highest content. It is an essential fatty acid that cannot be sy...
