Decolorizing method for sea buckthorn fruit oil, decolorized sea buckthorn fruit oil and application thereof

Abstract

The invention relates to the field of oil decolorization and specifically provides a decolorizing method for sea buckthorn fruit oil, the decolorized sea buckthorn fruit oil and an application thereof. The decolorizing method for the sea buckthorn fruit oil comprises the following steps: adding an adsorbent into the sea buckthorn fruit oil, and then, carrying out mixing decolorization at the temperature of 90-100 DEG C for 20-60min to obtain a decolorized mixture, wherein the addition amount of the adsorbent accounts for 12%-18% of the mass of the sea buckthorn fruit oil; and then, cooling the decolorized mixture, and finally, filtering the decolorized mixture to obtain the decolorized sea buckthorn fruit oil, wherein the adsorbent is activated clay, or a combination of aluminum hydroxide gel, amorphous aluminum hydroxide and bentonite, or a combination of activated clay, aluminum hydroxide gel and amorphous aluminum hydroxide. The method has the advantages of short time, high efficiency, high quality and low cost for sea buckthorn fruit oil decolorization, and nutrient ingredients of the decolorized sea buckthorn fruit oil is not lost.

Description

technical field [0001] The invention relates to the field of oil decolorization, in particular to a decolorization method of seabuckthorn fruit oil, decolorized seabuckthorn fruit oil and application thereof. Background technique [0002] Seabuckthorn fruit oil is a brownish-red clear and transparent oily liquid obtained from high-quality selected seabuckthorn fruits through juice extraction, high-speed centrifugal separation, and plate-and-frame pressure filtration. It has the unique aroma of seabuckthorn fruits. Seabuckthorn fruit oil is rich in more than 100 kinds of biologically active ingredients, and has comprehensive and multi-faceted curative effects in clinical medical observations, such as lowering blood fat, anti-ulcer, improving immunity, and beauty. Seabuckthorn fruit oil is composed of palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid and other beneficial fatty acids, of which unsaturated fatty acids are as high as 70%, ca...

Problems solved by technology

[0003] However, because seabuckthorn fruit oil contains a large amount of carotenoids, the color is dark brown red, and the appearance is not good. It is used as an additive for medicines, health products, food or cosmetics, or directly eaten because it affects the appearance and color of the product. While affecting product sales and use, decolorization of seabuckthorn fruit oil can improve the appearance and color of seabuckthorn fruit oil, enhance market acceptance, and increase product added value

[0004] The patent application text with the publication number CN104593148A provides a decolorization method of seabuckthorn fruit oil, but the decolorization temperature of seabuckthorn fruit oil in the decolorization method in CN104593148A is between 140-160°C, and high temperature is easy to destroy the nutritional components of seabuckthorn fruit oil , and the decolorization time is 2-3h, the time is too long, the decolorization efficiency is low, and the production cost is high
