Problems solved by technology

[0002] Since some fresh goji berries are not equipped with dust-proof and fly-proof facilities during the natural drying process, flies, insects, and dust fall during the drying process, causing the microbial indicators of goji berries to exceed the standard; The increased contact area with the air makes wolfberry fruit powder very susceptible to bacterial contamination and rapid growth, making it very easy for wolfberry fruit powder to exceed the standard of microorganisms

Embodiment 1

[0024] The method embodiment of circulating steam of the present invention to the sterilization of Lycium barbarum fruit powder, its steps are:

[0025] Spread wolfberry fruit powder on a porcelain plate with a thickness of 1 cm, cover the surface with a layer of gauze, place it in a circulating water steam sterilizer, and pass in water steam. When the temperature rises to 100°C to 110°C, the internal pressure is 0.1Mpa , and count for 20 minutes, take it out when the pressure of the circulating steam sterilizer drops to zero, and put it in a clean room to cool. The circulating water steam sterilization cabinet adopts the YXQ-WF2122 rectangular steam sterilization cabinet produced by Hengyang Hechuang Pharmaceutical Machinery Technology Co., Ltd.

[0026] Lycium barbarum fruit powder (unsterilized):

[0027]

[0028] Results: Before sterilization, each gram of wolfberry fruit powder contained 16×10 4 Colony count (CFU).

[0029] The detection method of the total number o...

Abstract

The present invention discloses a circulation steam sterilization method for Chinese wolfberry fruit powder. The method is mainly characterized in that the Chinese wolfberry fruit powder is placed in a circulation steam sterilization cabinet and subjected to a high-temperature short-time treatment after steam is introduced, and then the steam treated Chinese wolfberry fruit powder is taken out and placed in a clean room for cooling and packaging. The effective Chinese wolfberry fruit powder microorganism killing method can improve the quality of the Chinese wolfberry fruit powder, does not produce any residues, waste water and emissions, and is free of secondary pollution during the treatment process. The circulation steam sterilization method is short in time and thorough in sterilization effect, does not affect active ingredients in the Chinese wolfberry fruit powder, and is simple and convenient, and easy to be implemented.

Description

technical field [0001] The invention belongs to the technical field of food sterilization, in particular to a method for sterilizing wolfberry fruit powder by flowing steam. Background technique [0002] Since some fresh goji berries are not equipped with dust-proof and fly-proof facilities during the natural drying process, flies, insects, and dust fall during the drying process, causing the microbial indicators of goji berries to exceed the standard; The increased contact area with the air makes the wolfberry fruit powder very susceptible to bacterial contamination and rapid growth, which makes it very easy for the wolfberry fruit powder to exceed the standard of microorganisms. [0003] Advantages of water vapor: [0004] 1 Fast processing rate: Since the specific heat and heat transfer coefficient of water vapor are larger than those of air, and the mass transfer resistance in the drying medium of water vapor is negligible, the processing cycle can be significantly shor...
