The present application relates to a kind of meat product colorant based on double enzyme cascade reaction and coloration method and application, belong to meat science and technology field.The meat product colorant is composed of recombinant glucose dehydrogenase and one oxygen fusion enzyme NOS-YkuN-YumC of producing nitric oxide.The present application is by constructing the nicotinamide adenine dinucleotide phosphate (NADPH) regeneration system based on glucose dehydrogenase in recombinant bacillus subtilis, realize the continuous supply of key cofactor NADPH, to significantly enhance the catalytic activity of one oxygen fusion enzyme NOS-YkuN-YumC of producing nitric oxide under low temperature condition.It is applied to meat product, and the produced one oxygen is combined with myoglobin efficiently, generates nitrosylmyoglobin, so that meat product can obtain ideal red color even in low temperature processing with sodium nitrite treatment.The present application provides efficient and feasible solution for replacing nitrite coloration and improving meat product safety.

This invention belongs to the technical field of Chinese medicinal material drying equipment, and discloses a sulfur-free drying device for white peony root, including a drying chamber, a storage structure for placing white peony root, and a storage rack for supporting the storage structure. Both the storage structure and the rack are located inside the drying chamber. The storage structure includes a tray and a protective cover. Air inlets and outlets are evenly distributed on the side walls of the tray and the protective cover, and several ventilation holes are evenly distributed on the inner walls of both the tray and the protective cover. During drying, hot air flows upward through the ventilation holes and passes through multiple storage structures. Simultaneously, a shaking structure drives the storage structures to shake. During this process, powder generated by the shaking or hot air is carried up by the upward airflow. At this time, the ventilation holes in the protective cover actively draw in air, promptly removing the powder suspended above the storage structure. This prevents the powder from adhering to the surface of the upper material under the influence of the rising airflow, solving the problem of unevenly colored peony root slices and ensuring a smooth, uniform color, thereby improving the product's appearance and grade.

This utility model belongs to the field of tobacco machinery technology, specifically relating to an automatic detection and control device for color changes of materials in a tobacco curing machine. The device includes a tobacco curing machine, an analysis system, a control system, and a camera. This application achieves precise image acquisition and comparison of the material's state before and after curing by installing cameras at the inlet and outlet of the curing machine and combining them with RFID card positioning technology. Utilizing an intelligent analysis system to process and analyze the images in real time, the degree of color change in the tobacco leaves can be accurately calculated, and the maturity of the tobacco leaves can be predicted through advanced data analysis models. This provides a scientific and reliable basis for precise control of the curing process, avoiding the subjectivity and uncertainty of traditional manual judgment.

Including boiled pool and connecting installation in the fixed frame of boiled pool side, fixed frame connection installation has the outer circulating pump, and the outer circulating pump is connected with the boiled pool through first pipe line, and the fixed frame upper end connection installation has the filter, and the outer circulating pump water outlet is connected with the filter water inlet through second pipe line connection installation, and the filter water outlet connection installation has the backwater pipe of the intercommunication boiled pool, and the backwater pipe is installed with the pigment detector, and the fixed frame connection installation has the quantitative pump and pigment box, and the pigment box is connected with the quantitative pump inlet through third pipe line connection installation, and the quantitative pump outlet connection installation has the fourth pipe line of the intercommunication boiled pool, and the inside of boiled pool is equipped with temperature measuring device and heating sheet. The automatic detection color and lustre's boiled colouring pool device can filter out the impurity in the boiled colouring pool effectively, ensure the stability of the water quality of the boiled colouring pool, prolong the service period, reduce the cost of repeated water change, add pigment and heat.

The application discloses a hibiscus fabric and a preparation method thereof. The fabric is dyed by at least one of natural fiber fabric, chemical fiber fabric and blended or interwoven fabric of natural fiber and chemical fiber with hibiscus natural dye. The hibiscus natural dye is prepared by extracting and purifying hibiscus plant raw material with distilled water or pure water. The dyeing process of the fabric is carried out under the temperature condition below 60 DEG C. The dyeing wastewater can be recycled after treatment. The hibiscus fabric and the preparation method thereof adopt pure water to extract hibiscus pigment, and the dye does not contain heavy metal mordant and chemical synthetic components. The dyed fabric is skin-friendly and non-toxic, and meets the ecological textile standard. Through optimization of the extraction and dyeing process, the dyeing temperature is controlled below 60 DEG C, the damage of high temperature to anthocyanin pigment structure is effectively avoided, the natural color of the hibiscus dye is maintained, and the energy consumption is greatly reduced.

This invention belongs to the field of aluminum pigment technology, specifically relating to an aluminum pigment colored with an amine-based bio-based dye and its preparation method. The preparation method includes: modifying the amine-based bio-based dye by reacting it with a silane coupling agent containing epoxy groups; then loading the modified bio-based dye onto the surface of aluminum powder, forming Al-O-Si covalent bonds while simultaneously coating and coloring the aluminum powder. The colored aluminum pigment prepared by this invention has advantages such as green and sustainable raw material sources, stable color, excellent adhesion, and good corrosion resistance, and the preparation process is simple and the conditions are mild. The product of this invention can be widely used in fields with high safety requirements, such as infant products, food packaging, and cosmetics.

This invention discloses a highly stable, high-brightness, fast-dissolving, dust-free natural blue composition granules, its preparation method, and its applications, belonging to the field of pigment extraction technology. This natural blue composition uses gardenia blue, butterfly pea flower extract, and phycocyanin extract as the ternary coloring components, compounded with buffers (phosphates) and antioxidants (vitamin C and tea polyphenols), and employs an embedding wall material (β-cyclodextrin and sodium caseinate) for emulsification and embedding. Finally, it is produced into composite granules through spray drying and dry granulation processes. The composition granules exhibit a bright and vibrant color, excellent light and heat resistance, rapid dissolution in water without dust generation, and are environmentally friendly. This invention also provides a method for preparing the composition granules and their application as a colorant in food, pharmaceuticals, and cosmetics, offering a safe, stable, and efficient comprehensive solution to replace petroleum-based synthetic blue pigments.
