Preparation method for hemp seed oil microcapsules

Abstract

The invention discloses a preparation method for hemp seed oil microcapsules. The preparation method comprises the following steps: (1) preparation of a wall material solution : taking maltodextrin, modified starch, Arabic gum and saccharose as main wall materials, and mixing the main wall materials and water to prepare the wall material solution; (2) sterilization: sterilizing the wall material solution; (3) emulsification: mixing and emulsifying the sterilized wall material solution and hemp seed oil to obtain an emulsion; (4) drying: spray-drying the emulsion to obtain the hemp seed oil microcapsules. The hemp seed oil microcapsules prepared by the method have the advantages of high oil content, high encapsulation rate, good stability and long quality guarantee period; the method is simple, lower in cost and conductive to practical production and application, and brings better economic benefits.

Description

technical field [0001] The invention relates to a preparation method of vegetable oil microcapsules, in particular to a preparation method of hemp seed oil microcapsules. Background technique [0002] Hemp is an annual Moraceae plant and one of the native plants in my country. As a precious "longevity hemp", hemp is rich in plant protein, lecithin, vitamin E, selenium, zinc, manganese, germanium and other essential trace elements for human body, and is also known as "plant brain". The a-linolenic acid in "gold" can inhibit allergies, anti-inflammatory and antibacterial, and has the effects of laxative, nourishing and tonifying. The oil content of hemp seeds is 30% to 35%, the oil content of hemp seeds is more than 50%, the unsaturated fatty acids in hemp seed oil account for more than 85% of the total fatty acids, and the vitamin E content is also quite high, which has great development and utilization. value. [0003] As the extract of hemp seed, hemp seed oil has the ef...

However, in the embedding process, the gum arabic powder needs to be dried in a drying oven to remove the oxidase, and the process is complicated; the embedding stage needs to use HAc to adjust the pH value to 3.0-3.5, and whether the change of the pH value has an impact on the microcapsule product cannot be determined. Conclusive, and the microcapsule emulsion needs to be maintained at 45~55°C during the embedding process. After adjusting the pH value, add distilled water, and the temperature should be lowered to 30~35°C, and then quickly add ice to bring the temperature down to 10°C. The change is too complicated; the drying method is dripping curing agent, natural precipitation, vacuum freeze-drying, high cost, long cycle, different degrees of agglomeration may occur, and poor fluidity

Chinese patent application CN102934703A "A Linseed Oil Microcapsule and Its Production Method" reports the preparation and production method of the linseed oil microcapsule, and its linseed oil load can reach 45%, and the embedding rate is ≥ 90%. , in its embodiment one, the drug loading is 19%, and the embedding rate can reach 95%; in the example three, the drug loading is 45%, and its embedding rate is reduced to 90%; it can be seen that with modified starch, maltodextrin and casein Although the embedding effect of sodium bicarbonate as a compound wall material is better, the embedding rate decreases rapidly with the increase of drug loading.

Although its drug loading can reach 45%, its embedding rate is only 90%, which cannot protect linseed oil well
