The method has important significance in analyzing the genetic regulation and control mechanism of the tocopherol content of the sesame, cultivating new varieties of the sesame with high tocopherol content and improving the nutritional quality of the sesame.

This invention discloses a method for promoting polyphenol accumulation in mung bean sprouts, comprising the following steps: first, soaking mung bean seeds and then evenly spreading them in a germination box, rinsing them with a methyl jasmonic acid solution; then moistening them with the methyl jasmonic acid solution, irradiating the moistened mung bean seeds with monochromatic light, and culturing them to the embryonic stage to obtain high-polyphenol mung bean sprouts; the wavelength of the monochromatic light is 380-500 nm, and the light intensity is 10-20 μmol·m⁻¹. ‑2 ·s ‑1 This invention also discloses a high-polyphenol mung bean sprout. This invention synergistically treats mung bean sprouts with methyl jasmonic acid and monochromatic light. By controlling the concentration of the methyl jasmonic acid solution and the wavelength and intensity of the monochromatic light, it effectively promotes the accumulation of polyphenols in mung bean sprouts, cultivating a mung bean sprout with a high total polyphenol content. This invention provides theoretical support for cultivating high-value-added mung bean sprouts. Its pretreatment method is simple to operate, suitable for large-scale promotion, and has good economic benefits.

This invention relates to the field of feed resource development technology, specifically to a solid-state fermentation process for soy sauce residue. Through the synergistic effect of desalination pretreatment and mixed-culture solid-state fermentation, the nutritional quality of the soy sauce residue is significantly improved. This invention also provides the application of solid-state fermented soy sauce residue in broiler diets. The beneficial effects of this invention are: fermented soy sauce residue can be directly used as a protein feed ingredient to partially replace soybean meal, with a stable source and low cost. This not only reduces breeding costs and dependence on imported soybean meal but also realizes the resource utilization of soy sauce residue, conforming to the concepts of circular economy and sustainable development in the feed industry.

This invention discloses a method for preserving the green color of leafy green vegetables used in fillings. The method involves first irradiating fresh leafy vegetables with alternating low-intensity pulsed light and ultraviolet C rays to maintain the integrity of the chloroplasts. Next, the irradiated leafy vegetables are subjected to enzyme inactivation and sterilization. Then, the vegetables are soaked in a solution of maltodextrin and sodium caseinate, dried, and finally cut, seasoned, stuffed, steamed, packaged, and refrigerated at 4°C to obtain a pre-prepared dish containing green vegetables. Vegetables processed using this method show a particularly significant improvement in green preservation after reheating following one week of refrigeration at 0°C–4°C. The preparation method provided by this invention is simple, uses pollution-free and inexpensive raw materials that are readily available, and solves the problem of yellowing and softening of leafy green vegetables during processing and storage, demonstrating its feasibility for application.

The invention discloses a method for evaluating the comprehensive quality of blackberry interspecific hybridization single plants, which comprises the following steps: 1) taking blackberries as female parents and wild rubus corchorifolius as male parents to obtain blackberry F1 generation interspecific hybridization seedling groups; (2) collecting mature fruits of each single plant of the F1 interspecific hybrid population, and measuring various appearance quality indexes and nutritional quality indexes of the fruits to obtain character data of each fruit; (3) obtaining a correlation rule among the characters through correlation analysis; and 4) performing principal component analysis by calculating and comparing the contribution rate and the characteristic value of the fruit character, calculating to obtain the weight of each principal component, constructing a fruit comprehensive evaluation model, and obtaining the comprehensive evaluation score of the hybrid F1 single plant according to the model. The method for optimizing the interspecific hybrid plants of the blackberries through comprehensive evaluation of fruit characters is explored for the first time, the evaluation indexes obtained by the method can be used for rapidly and effectively screening out the hybrid single plants with excellent comprehensive characters, and the method has a good application prospect in quality breeding of the blackberries.

This invention relates to the field of agricultural environmental remediation and plant nutrition regulation technology, specifically to a passivation culture medium for reducing cadmium in rice and its preparation method. The culture medium consists of ferric citrate complex solution, sodium polyaspartate graft, potassium dihydrogen phosphate, choline-stabilized orthosilicate mother liquor, and zinc disodium ethylenediaminetetraacetate hydrate. During preparation, a stable system is synergistically constructed through multi-coordination complexation, electrostatic regulation, and organic framework stabilization mechanisms. This culture medium maintains good dispersibility and stability under acidic and hard water conditions, forming a weakly acidic to neutral buffer zone in the rice rhizosphere, effectively reducing the migration and absorption of cadmium ions while maintaining the availability of nutrients such as iron and zinc. This significantly reduces the cadmium content in rice grains, improves crop nutritional quality and environmental adaptability, and is suitable for the efficient and safe remediation of cadmium-contaminated paddy fields.
