V-seal / Food preservation product for poor people


There is no good way to store food in poor areas of Africa. Food spoils easily and has to be discarded. Because of the shortage of food, some people do not want to discard food, eating rotten or moldy food leads to Salmonella infection and other food poisoning problems. V-seal provides a convenient and cheap way to store food. It can be used as a food container to seal the leftover food directly after eating. It can also replace the refrigerator to store some grains and meat. There is a label on the outside of the silica gel bag that shows the acidity and alkalinity of the food, which can be used to help judge whether the food has gone bad.
