Embodiment 1

[0017] During the betel nut production process, the sliced ​​betel nut slices are transported to the pulse light source for processing with the conveyor belt, and the pulse light intensity is adjusted to 1kJ / cm 2 , the pulse width is 10us, and the number of flashes is 9 times. Such as image 3 As shown, there are two kinds of conveyor belts where betel nut sheets pass through the pulsed strong light: mesh surface and mirror belt, which pass through the first three-sided pulsed flash light source 30, the first horizontal flashed light source 40, and the second three-sided pulsed flashed light source. The light source 31 and the second horizontal flash light source 41 . When the betel nut passes through two horizontal flash light sources, the mirror surface vibrates, the betel nut jumps up, and the mirror surface reflects strong light for sterilization. Three-sided pulsed light source such as figure 1 As shown, the three-sided pulsed light source is irradiated directly above ...

Embodiment 2

[0020] During the production process of betel nuts, after being sliced, they are treated with brine, and the three pulsed light intensities are adjusted to 8kJ / cm 2 , the pulse width is 3us, and the number of flashes is 4 times. Such as image 3 As shown, there are two kinds of conveyor belts where betel nut sheets pass through the pulsed strong light: mesh surface and mirror belt, which pass through the first three-sided pulsed flash light source 30, the first horizontal flashed light source 40, and the second three-sided pulsed flashed light source. The light source 31 and the second horizontal flash light source 41 . When the betel nut passes through two horizontal flash light sources, the mirror surface vibrates, the betel nut jumps up, and the mirror surface reflects strong light for sterilization. Three-sided pulsed light source such as figure 1 As shown, the three-sided pulsed light source is irradiated directly above the betel nut shell at 180° horizontally, and the...

Embodiment 3

[0022] During the production process of betel nuts, after being sliced, they are treated with brine, and transported to the pulse light source for processing. The three pulse light intensities are adjusted to 7kJ / cm respectively. 2 , the pulse width is 4us, and the number of flashes is 5 times. Such as image 3 As shown, the processed betel nut slices are transported to the three-sided pulsed light source along with the conveyor belt for processing. The conveyor belts where the betel nut slices pass through the pulsed strong light are two types: mesh surface and mirror belt, and pass through the first three-sided pulsed flash light source 30 successively. , the first horizontal flash light source 40 , the second three-sided pulse flash light source 31 , and the second horizontal flash light source 41 . When the betel nut passes through two horizontal flash light sources, the mirror surface vibrates, the betel nut jumps up, and the mirror surface reflects strong light for ster...

Abstract

The invention belongs to the technical field of food processing, relates to a food sterilization method and in particular relates to a pulsed intensive light sterilization method for betel nuts. The method is characterized in that a pulsed intensive light processing process is increased on a betel nut processing production line, wherein pulsed light source irradiation is adopted in the pulsed intensive light processing process, the light intensity is 1-8kJ/cm<2>, the pulse width is 3-10 microseconds, and the flash frequency is not less than 4 times. The pulsed intensive light processing process is performed after a betel nut processing and slicing process, the sterilized betel nuts penetrate through the pulsed intensive light processing process along with conveyor belts before a packaging process, and the conveyor belts comprise a meshed belt and a mirror surface belt which are sequentially arranged at an interval, the meshed belt adopts a three-sided light source irradiation mode comprising 180-degree horizontal top irradiation for betel nut shells and 75-85-degree irradiation on two sides, and the mirror surface belt adopts a top horizontal flash light source. The method has the beneficial effects of uniform irradiation, good sterilization effect, high production efficiency, capability of obviously prolonging the quality guarantee period of the betel nut products, slight influence on quality of the betel nut products and the like.

Description

technical field [0001] The invention belongs to the technical field of food processing and relates to a food sterilization method, in particular to a pulse strong light sterilization method for betel nuts. Background technique [0002] Betel nut is an evergreen tree belonging to the palm family. Its seeds are called betel nut. It contains arecoline and tannic acid. Edema, athlete's foot embolism. Betel nut enjoys the reputation of "plant chewing gum". After eating, it can produce danjin, and the face will turn red after eating, just as Su Dongpo described in his poem, "The flushed cheeks were once charming, but who knows that you are drunk with betel nuts." Betel nuts are widely cultivated in China, India, Sri Lanka, Thailand, Malaysia, and the Philippines. Since ancient times, betel nuts have been a good fruit for residents in the southeastern coastal provinces of China to welcome guests and entertain relatives and friends. [0003] Since betel nut processing follows the ...
