Abstract

The invention discloses a high-voltage electric field low-temperature plasma cold sterilization method for packaged betel nuts. A betel nut product is put into a packaging bag (box) and the packagingbag (box) is filled with gas for sealed packaging, and the packaging bag (box) is placed between two electrodes of a high-voltage electric field plasma sterilization device under the condition of roomtemperature and relative humidity of 50 to 95% RH, and adopts a short-time-interval-multiple sterilization method under the conditions that the processing voltage intensity is 15 to 30 kv / cm, the single electric field action time is 20 to 40 seconds and the interval time is 30 to 90 seconds, and the treatment is repeated for 3 to 5 times. The packaged betel nuts use the high-voltage electric field plasma short-time-interval-multiple sterilization method to significantly improve the sterilization effect under the condition of ensuring the sensory quality of betel nuts, and the short-time-interval-multiple sterilization method can meet the large-scale automatic production requirements of packaged betel nut products.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a high-voltage electric field low-temperature plasma cold sterilization method for packaging betel nuts. Background technique [0002] In recent years, the production technology of edible betel nut has been greatly developed, but most of its processing technology adopts traditional labor-intensive processing technology, the sanitation is poor, and it is easy to be polluted by microorganisms during the processing process, resulting in the microbial total of betel nut products. If the quantity exceeds the standard, it will affect its shelf life. At present, the processing of betel nuts mainly reduces the number of microorganisms by adding different preservatives, ultraviolet radiation, and irradiation. However, the bactericidal effect of these methods is not ideal, and the effect of prolonging the shelf life of the betel nut is not obvious, and the quality of the betel nut...
