This invention discloses a method for processing crude oil for soy sauce that reduces amino acid nitrogen loss and precisely controls color, comprising the following steps: heating and sterilization: heating and sterilizing the crude oil and then instantly cooling it to 50-60°C to obtain semi-finished product A; heat sinking: pumping the semi-finished product A into a sealed heat sinking tank for heat sinking; then extracting oil from the middle of the heat sinking tank to obtain semi-finished product B; filtration and blending: filtering the semi-finished product B and then blending it to obtain semi-finished product C; controlled thermal reaction: heating and sterilizing the semi-finished product C and then instantly cooling it to 65-90°C, pumping it into a stainless steel tank containing a steam coil for a slow Maillard reaction at a sustained temperature, which is a controlled thermal reaction; if the crude oil being processed is light in color, liquid caramel coloring is added to the semi-finished product C during the controlled thermal reaction process to increase the bright red color and make its color meet the process design requirements; bottling: after the controlled thermal reaction is completed, bottling is performed to obtain the finished soy sauce.

The invention relates to the technical field of food processing, and provides an optimized packaging method of chilled fresh meat, which comprises the following steps: carrying out acid discharge treatment on livestock meat to obtain acid-discharged fresh meat; placing the acid-discharged fresh meat in a sealable package, and vacuumizing the sealable package to obtain packaged fresh meat; the packaged fresh meat is temporarily heated in a heating medium for a first preset duration, and the heated fresh meat is taken out after the first preset duration; and refrigerating the heated fresh meat. Through the above configuration, the water loss rate of the meat product during the vacuum storage period is effectively reduced, so that the meat product can still keep the meat color close to bright red after being stored for a quite long time; and bacterial colony reproduction during the storage period can be more effectively inhibited.

The invention discloses a sulfur-free big red star anise processing method based on endogenous metabolism precursor regulation and application, mature star anise fresh fruits with yellow peels and full seeds are used as raw materials, and the processing method sequentially comprises three links of ultraviolet stress pretreatment, short-time hot water fixation and segmented drying. Through ultraviolet treatment, red precursor metabolites such as reduced glutathione, phenolic acid, flavone, stilbenes and sugar phosphoric acid are enriched in the fruits; the polyphenol oxidase is rapidly inactivated through short-time hot water fixation, the precursor pool is stabilized, and the quality loss is controlled; in the drying stage, the precursor is promoted to be gradually converted into phenolic acid oxidation products, aromatic aldehyde, aromatic amino acid-containing small peptides and terpenoid aroma substances in a sulfur-free environment, and stable bright red color and typical aroma are formed. Compared with a traditional sulfur fumigation process, the method has the advantages that the bright red star anise with high red brightness, low fruit cracking rate, natural flavor and remarkably reduced sulfur residue risk can be obtained under the condition that sulfur is not used, and the method is suitable for green and safe processing and standardized production of the star anise industry.

The invention belongs to the technical field of ceramic pigments, and discloses a coated ceramic pigment, a preparation method thereof and ink-jet printing ceramic ink. The preparation method of the coated ceramic pigment comprises the following steps: adding a zirconium source and a cadmium source into water, and mixing to obtain a solution A; adding a sulfur source, a selenium source, a silicon source and inorganic base into water, and mixing to obtain a solution B; dropwise adding the solution A and the solution B into an aqueous solution containing a dispersing agent together, and stirring to obtain a mixed solution; dropwise adding an aqueous solution of alkali metal salt into the mixed solution, continuously stirring, and carrying out suction filtration and drying to obtain a precursor; and mixing the precursor with a mineralizing agent, and calcining to obtain the catalyst.
