The present application relates to a kind of preparation method of immunoglobulin powder and its application, the preparation method includes the following steps: collecting bovine colostrum, using cell survival technology is frozen;Frozen bovine colostrum is thawed, carries out milk fat separation, and obtains defatted bovine colostrum;Defatted bovine colostrum and composite rennet are mixed and are curdled, and then broken, obtain whey;The composite rennet includes aspartic protease, papain and bromelain;Whey is ultrafiltrated, and immunoglobulin solution is obtained;Immunoglobulin solution is vacuum freeze-dried, and the immunoglobulin powder is obtained.The preparation method provided by the present application is low temperature all the way, the activity of immunoglobulin is retained to the greatest extent, the use of composite rennet solves the problem of curd failure, and each link cooperates to improve the curd effect, realizes the preparation of high-efficiency, high-purity and high-quality immunoglobulin powder.

The present application relates to a kind of ferulic acid cyclodextrin inclusion compound and its preparation method and a kind of method for enhancing the water retention of muscle fiber protein hydrogel, belong to meat protein processing technical field.The preparation method of the ferulic acid cyclodextrin inclusion compound of the present application is, ferulic acid solution is mixed with cyclodextrin solution, and mixed solution is obtained;Mixed solution is dried, and cyclodextrin inclusion compound is obtained, solve the problems such as low water solubility of ferulic acid, poor stability etc.The present application also provides a kind of method for enhancing the water retention of muscle fiber protein hydrogel, specific method is, muscle fiber protein solution is mixed with ferulic acid cyclodextrin inclusion compound, heat treatment, by adding ferulic acid cyclodextrin inclusion compound, the water retention of muscle fiber protein gel is significantly improved.Therefore, the present application provides a kind of processing method of meat product with excellent quality, nutritional health and can be widely applied.

This invention provides a method and system for producing cyclohexyl hydrogen peroxide by cyclohexane oxidation. The method includes the following steps: reacting cyclohexane with an oxygen-containing gas containing CO2 to obtain a material containing cyclohexyl hydrogen peroxide. The method of this invention improves the yield and selectivity of cyclohexyl hydrogen peroxide by reacting the feed cyclohexane with an oxygen-containing gas containing CO2, reduces production costs, requires less equipment investment, and has a simple operation process. It can be used in the continuous industrial production of cyclohexane to cyclohexyl hydrogen peroxide via air oxidation.
