The invention relates to the field of control, and particularly provides an intelligent regulation and control method and system for egg preservation based on environmental perception and a storage medium, and the method comprises the steps: collecting temperature, humidity, carbon dioxide concentration and illumination intensity data of an egg preservation environment in real time; determining time-varying reference weights of the temperature, the humidity and the carbon dioxide concentration according to the fresh-keeping duration, and performing weighted summation and correction in combination with an illumination intensity accumulated integral value to obtain a comprehensive deterioration index of the current period; calculating a deterioration fluctuation gradient of the index in a preset time window and an accumulated deterioration index from the beginning of fresh keeping; constructing a three-dimensional regulation and control decision space taking the three indexes as dimensions, and mapping the indexes to generate a fresh-keeping environment regulation and control instruction set; and detecting whether the temperature and the humidity are subjected to synchronous step change or not, if so, superposing the step penalty increment to an accumulated metamorphic index, pausing the original instruction set within a preset duration, and executing the strong intervention regulation and control instruction.

The invention relates to the field of egg fresh-keeping equipment, and discloses an egg efficient fresh-keeping and quality grading method and device with intelligent environment regulation and control, and the key point of the technical scheme is that the egg efficient fresh-keeping device with intelligent environment regulation and control comprises a fresh-keeping box body; the first partition plates are arranged in the fresh-keeping box body and divide the interior of the fresh-keeping box body into a plurality of fresh-keeping layers; the first box body, the second box body and the air inlet paths corresponding to the fresh-keeping layers are arranged on the outer side of the fresh-keeping box body, so that cold air can be conveyed into the corresponding fresh-keeping layers according to layers, and the problem that the regulation and control pertinence on the egg storage environment of each layer is insufficient when air is supplied to the whole cabinet in a unified mode is solved. Secondly, by arranging a structure in which drawer position change is matched with air inlet switching, when the drawer leaves the preset position, direct air inlet of the corresponding layer is stopped, cold air is stored, the stored cold air is conveyed to the corresponding fresh-keeping layer after the drawer returns to the original position again, and therefore invalid leakage of the cold air along an opening path is reduced; and the time required for the corresponding fresh-keeping layer to recover to the fresh-keeping state before and after pulling is shortened.

This invention provides a method for improving the quality deterioration of eggs during storage through electron beam irradiation. This method can significantly improve the quality deterioration of green food eggs during storage and belongs to the field of egg preservation technology. This invention uses an electron beam with an energy not exceeding 10 MeV generated by an electron accelerator. Under the premise of ensuring food biosafety, and within a determined effective dose range (0.5-2 kGy), and under the same environmental conditions (20℃, 70%RH), the dynamic changes in egg quality at different storage time points (0 days, 7 days, 14 days, 21 days) are systematically investigated. Simultaneously, combined with a comparative analysis of the quality characteristics and nutritional value of green food eggs, the optimal electron beam irradiation dose range for egg preservation is finally determined to be 0.5-1.5 kGy.

The present application relates to a kind of egg-laying hens premix with DHA efficient enrichment and egg preservation, and application thereof, belong to animal nutrition and feed technology field.The present application first clearly that phospholipid deficiency is the core reason of limiting DHA enrichment efficiency, reveals that soy lecithin promotes the molecular mechanism of DHA deposition by up-regulating FABP, PCTP expression, and proves that astaxanthin through direct free radical scavenging and the double synergistic antioxidant mechanism of activating endogenous antioxidant enzyme system.Based on this, with microencapsulated schizochytrium sp powder, high-purity soy lecithin, astaxanthin as core component, compound probiotics, lutein, organic selenium, construct four-effect synergistic premix formula, and establish "DHA enrichment-egg quality-shelf life" linkage parameter system.Application of the present application, egg DHA enrichment amount reaches 500~1000 mg / 100 g yolk, feeding 2 weeks stable enrichment, egg production rate keeps more than 85%, shelf life is extended by 15~20 days, with efficient nutrition fortification and preservation function.

The invention discloses an egg fresh-keeping quality evaluation method and device and a medium, and relates to the technical field of food detection, and the method comprises the steps: adjusting the transmitting power of a transillumination light source according to the gray level distribution of a reference transillumination image under the condition of keeping a reference space attitude unchanged, forming a perturbation transillumination condition, and obtaining a perturbation transillumination image; a transillumination image is collected through an image sensor under the disturbance transillumination condition, and a disturbance transillumination image is obtained; in a unified image space coordinate, respectively executing space gradient calculation on the reference transillumination image and the disturbance transillumination image, and calculating a transillumination structure maintenance operator according to the change condition of gradient amplitude distribution; and determining a structure boundary mask region according to the gradient magnitude distribution of the reference transillumination image, and performing interval judgment on the fresh-keeping quality state of the to-be-evaluated egg in combination with the gradient change condition in the structure boundary mask region and a transillumination structure maintenance operator. Layered expression of overall space gradient change in the egg and structural boundary change of egg white, egg yolk, air chambers and the like is achieved.
