The technical scheme of the invention includes extracting medium spicy Capsaicin essence, preparation of oily capsaicin mixture and preparation of high-purity capsaicin are three process steps. The content of capsaicin in the prepared product is greater than 95%; the total yield is greater than 60%. The production process is simple and the separation is thorough; the yield of capsaicin is high. , and the by-products obtained in each step can be processed and used as pepper essence without waste; the solvents used in the production process are common solvents, which are easy to recycle and reuse, and have no environmental pollution; the selected chromatography medium can be regenerated and used repeatedly , low production cost; using capsicum extract as a raw material not only increases its added value, but also prolongs the industrial chain of capsicum processing.

The invention discloses a mechanism-friendly environmentally friendly carbon based on camellia oleifera husk, which comprises a carbon body with a triangular cross-section, through holes opened in the middle of both sides of the carbon body and penetrating through the carbon body, and filled into the through holes, Used to ignite the fiber filling inside the charcoal body; the charcoal body includes an inner charcoal frame, an outer charcoal layer laid on the outer surface of the inner charcoal frame, which is easy to burn, and the outer charcoal layer and the inner charcoal frame Close fit; the present invention uses the inner carbon frame to cooperate with the outer carbon layer to form a carbon body, and lays equidistantly distributed through holes in the middle of both sides of the inner carbon frame, and fills the through holes with fiber fillers, which can quickly ignite the charcoal body, and make the charcoal body burn more evenly. In addition, the charcoal body is small in size and can be arranged regularly and low in the combustion space, which can not only reduce the space occupation, but also make the heat disperse evenly. The production and preparation can fully improve the resource utilization rate of camellia oleifera after oil extraction.

The invention relates to a preparation process of multifunctional bamboo-shell organic-inorganic composite fertilizer, which comprises 60 to 70 parts of bamboo shell, 30 to 40 parts of manure and 0.5 to 1 part of micro-organism microbial inoculum (consisting of 40 to 50 parts of cellulose-decomposing bacteria, 30 to 40 parts of yeast and 10 to 20 parts of mesophile), and is characterized in that the above raw materials are fermented for 15 to 30 days, bamboo-shell organic fermentation materials are proportioned with conventional N, P and K inorganic fertilizer and middle-micro element fertilizer according to the nutrition required for different crops and different growth periods after being dried and crushed, the bamboo-shell resource can be transformed to the special organic-inorganic composite fertilizer with 20 to 40 percent of organic substance and 15 to 25 percent of nitrogen, phosphorous and potassium through pelleting, so the recycling of bamboo-shell waste is realized, and remarkable economic, social and ecological benefits can be created.

The invention provides a method for preparing stable zeaxanthin, which comprises the following steps: (1) removing starch from corn yellow powder, performing steam explosion treatment, then extracting with alcohol, collecting the supernatant after centrifugation, and obtaining crude zeaxanthin extracting solution; (2) carrying out membrane filtration and separation of the crude extract of zeaxanthin with a membrane with a molecular weight cut-off of 3000Da, collecting the permeate to obtain a purified zeaxanthin extract; (3) separating the purified zeaxanthin extract Carry out evaporation and concentration to obtain corn yellow pigment concentrated solution; (4) add microporous starch to corn yellow pigment concentrated solution and mix evenly, add gelatin and maltodextrin aqueous solution after drying to obtain mixed solution, then add ascorbyl palmitate to carry out Homogeneous emulsification treatment to obtain zeaxanthin mixed emulsion, spray drying to obtain microcapsule stabilized zeaxanthin finished product. The zeaxanthin prepared by the method of the invention has high yield and good stability.

The invention relates to technology for producing an organic fertilizer by using bamboo shoot hulls serving as raw materials through mixed compositing fermentation. The technology comprises the steps of: cutting and crushing the bamboo shoot hulls, performing screw extrusion dehydration on the bamboo shoot hulls, adding fermented ruminant manures into the bamboo shoot hulls, mixing the materials uniformly, and delivering the materials in a trench type fermenter for compositing fermentation; when the temperature of the materials rises to between 60 and 70 DEG C, performing stack-turning on thematerials for oxygen supply by using stack-turning equipment, and further dehydrating the materials; in a high-temperature period, performing the stack-turning at least once each day, and after acid content of the extruded juice is adjusted, returning the juice to the composting uniformly; and after the fertilization is completed, according to different purposes, packing the composting directly or packing crushed composting to obtain the organic fertilizer, or performing extrusion granulation on the composting to obtain the organic fertilizer. The technology is simple and feasible, can realize the resource utilization of the waste bamboo shoot hulls, does not generate secondary pollution, and provides a safe and pollution-free fertilizer for agricultural production while solving the pollution problem.

The invention relates to a method for preparing a fresh fish essence through processed freshwater fish leftover binary fermentation. The method comprises the following steps: (1) crushing, namely crushing the processed freshwater fish leftover to be 40-60 meshes; (2) endogenous enxymolysis, namely activating fish cathepsin through ph and temperature control and Ca<2+>, appropriately hydrolyzing fish protein, and reducing the system viscosity; (3) sterilizing and curing, namely adding lentinus edodes stem powder, heating at 121 DEG C for 30 minutes, steering and softening fish bones, and stimulating calcium and bone collagen to dissolve out; (4) inoculated fermentation, namely inoculating a high-temperature yeast and lactobacillus bulgaricus binary fermentation agent to ferment; (5) homogenizing; (6) concentrating; and (7) after ripening. The method has the advantages that a problem that the processed freshwater fish leftover is difficult to utilize is solved; a product is stable in taste, natural in flavor, rich in nutrition and rich in various beneficial ingredients; and a production technology is unified, simple and easy to standardize.

The invention discloses a preparation method for peptide chelated calcium of clanis bilineata tsingtauica larva. The preparation method comprises the following steps: degreasing the clanis bilineata tsingtauica larva and then carrying out superfine crushing, adding water and uniformly mixing, and adjusting the pH value to 2-9; adding protease in the obtained mixed liquid, stirring for enzymatic hydrolysis, then inactivating the protease to obtain a crude enzymatic hydrolysate, and centrifuging to obtain an supernatant liquid; taking the obtained supernatant liquid and removing impurities to obtain a purified liquid, and carrying out separation and purification by virtue of at least one ultrafiltration membrane with a molecular weight cut-off of 1-50kD to obtain enzymatic hydtolysis peptide components with different molecular weights; adding a calcium source, and chelating to obtain a crude peptide chelated calcium product of the clanis bilineata tsingtauica larva; and collecting precipitates after concentration and precipitation, and drying to obtain the peptide chelated calcium product of the clanis bilineata tsingtauica larva.
