NASA states “The food you eat and the medicine you take must be safe and retain their nutrient and pharmaceutical value, even while being bombarded with space radiation.” Radiation and non long lasting food stopping you. NASA also states “Good nutrition is critical on missions” The Food Freeze Machine can help. This machine is made out of copper so radiation will not affect it as much, it also works with Ice. You put ice in it and close the door. The cold air in any chamber will also go to the other chamber, making it as fast as a fridge. This can solve 2 problems. One is to repel radiation and it can also make the food last longer. You don't need batteries at all but you need ice and really small packages of food.
