Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1 preparation of white kidney bean extract
(1) Impurity removal treatment: filtering white kidney beans, removing impurities, screening out good-quality white kidney beans, cleaning and airing;
(2) low-temperature grinding: grinding white kidney bean at 4-20 deg.C, and pulverizing into 50-200 μm particle size;
(3) deodorizing treatment: soaking white kidney bean powder in water, adding a deodorizing composition consisting of eugenol, linalool, kaempferol and geraniol, and stirring to obtain a deodorizing bean liquid, wherein the ratio of the eugenol to the linalool to the kaempferol to the geraniol is 6:3:5: 2;
(4) drying and filtering treatment: adding colloid into the odor-removed bean liquid, shearing, emulsifying, filtering with 100 mesh sieve, spray drying, and filtering with 30 mesh sieve to obtain powdery white kidney bean extract.
Because the white kidney beans contain lipoxidase, when the epidermis is broken, the activity of the lipoxidase can be excited by contacting with oxygen, and the lipoxidase reacts with unsaturated fatty acid in the white kidney beans to generate various micromolecule volatile compounds, so that beany flavor is formed, and the eating experience of the white kidney beans is greatly influenced. When the beany flavor of the white kidney beans is removed, a heat treatment method is mostly selected, the lipoxygenase is inactivated at high temperature, the operation is simple, the cost is low, but high-quality protein contained in the white kidney beans is damaged, and the nutritional value of the white kidney beans is reduced. Therefore, the method for removing the beany flavor has good deodorizing effect, can ensure the nutritional value of the beany flavor, and has high economic benefit.
The white kidney bean processing and grinding are carried out in a low-temperature environment, so that the protein is prevented from being damaged by mechanical heat generation; researches find that the combination of eugenol, linalool, kaempferol and geraniol in a specific ratio can just cover the beany flavor and leave a light flavor, so that the flavor regulation is not influenced when the navy bean extract is added into bubble water.
