A kind of chitosan oligosaccharide aqueous solution nutritional bean sprouts cultivation method

Abstract

The invention discloses a method for cultivating nutritive soybean sprouts by using a chitosan oligosaccharide aqueous solution. The method includes the following steps: 1) preparation of a soybean sprout cultivation solution, wherein the concentration of chitosan oligosaccharide is 0.001-0.010 g / L, the chitosan oligosaccharide is dissolved in water with stirring, and the soybean sprout cultivation solution is obtained after the chitosan oligosaccharide is completely dissolved; 2) soybean soaking: soaking soybean seeds in water, removing impurities floating on a water surface, putting the soaked soybean seeds in a cultivation container, and cultivating the soaked soybean seeds by using the prepared soybean sprout cultivation solution; 3) cultivation: keeping the temperature being at 20-25 DEG C, keeping the humidity being in 85%-95%, performing dark cultivation, changing the cultivation solution for 3-4 times every day, cultivating the soybean sprouts for 3-5 days, and then harvesting the soybean sprouts when the length of the soybean sprouts reaches 4-6 cm. the obtained soybean sprouts are crisp and tender, have no harmful matters, are rich in nutriments, and are excellent in antioxidant quality; accumulation of nutriments of the soybean sprouts and the antioxidant quality can be improved.

Description

technical field [0001] The invention relates to the field of bean sprout cultivation, in particular to a method for cultivating nutritional bean sprouts in an aqueous solution of chitosan oligosaccharide. Background technique [0002] Bean sprouts have a crisp taste and are rich in various nutrients, and are deeply loved by consumers. Bean sprouts currently on the market are obtained from bean sprout seeds soaked in ordinary water and germinated. The resulting bean sprouts have low accumulation of nutrients and poor antioxidant quality; and the use of plant growth regulators to accelerate the growth of bean sprouts will lead to bean sprouts. The residual toxic and harmful substances exceed the standard, and long-term consumption will cause damage to the human body. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the invention provides a method for cultivating nutrient bean sprouts in an aqueous solution of chitosa...
