遠紅外線 一問 快快快!! (10)

I presume that you are asking the effect of using Far Infrared in a refrigerator in preserving food as compared with conventional method of freezing.
It has been said that the Far Infrared has a heating effect on the food so as to kill the germs and micro-organisms present on it. However, there is no scientific proof that such method of sterization is effective given the low energy of Far Infrared that may not be able to break the chemical bonds. Far Infared only causes molecular vibrations. Thus, the mere heating effect of Far Infrared is very limited.
Also, the penetration of Far Infrared is short and could not reach too deep into the food.
Therefore, the use of Far Infrared in food preservation sounds more like a scheme to cheat consumers out of their money than a real practical means.
The following two eb-pages give a good account on the use of Far Infrared in refrigerators:
