Problems solved by technology

[0004] Because okra seed oil is rich in unsaturated fatty acids, it is sensitive to light, oxygen, heat and other factors, and is easily oxidized and rancid during production and storage, resulting in a decrease in oil quality and a shortened shelf life.
Moreover, okra seed oil has the characteristics of difficult to control the dose, unpleasant smell of oil, and poor compliance when it is eaten directly, so it is difficult to be accepted by most people.
Simultaneously because okra seed oil has water insolubility, its application in liquid food is limited

Abstract

The present invention discloses abelmoschus esculentus seed oil microcapsules and a preparation method thereof. Firstly, abelmoschus esculentus seed oil is mixed with whey protein isolate, the mixtureis subjected to a high-speed dispersion to form an O/W type primary emulsion, then arabic gum is added, a pH value is adjusted, the whey protein isolate and the arabic gum undergoes a condensation reaction through electrostatic interactions to form a complex condensed phase precipitation around the abelmoschus esculentus seed oil emulsion droplets to obtain the microcapsules, a certain amount ofa curing agent is added to solidify, the washed precipitate is filtered to obtain wet microcapsules, and the wet microcapsules are dried to obtain the powdered abelmoschus esculentus seed oil microcapsule product. The abelmoschus esculentus seed oil microcapsules have advantages of being stable in preparation processes and being suitable for industrial productions, and the obtained abelmoschus esculentus seed oil microcapsules are fast in absorption, high in bioavailability, free of odor, and easily accepted by consumers, and provide ideas for developments of medicinal and health-care productsfor the abelmoschus esculentus seed oil.

Description

Technical field [0001] The invention belongs to the technical field of okra seed oil microcapsules, and specifically relates to a okra seed oil microcapsule and a preparation method thereof. Background technique [0002] Okra (Abelmoschus esculentus L.) is an annual herbaceous plant of the Malvaceae okra family, also known as Vietnamese sesame, hot pepper, lamb bean, tonifying kidney grass, etc. It is a kind of flower, vegetable, and medicinal plant. High vegetables have broad prospects for development. Due to the short maturity period of okra squash, if it is not harvested in time, the meat quality will quickly age, the fiber will increase, the edible value will be reduced or even inedible, resulting in a great waste of resources, increasing the risk of farmers planting okra, and restricting okra The healthy development of the industry. [0003] Mature okra seeds contain a lot of oil, the content is 20 to 26%, the oil is rich in fatty acids, such as myristic acid, palmitic acid,...
