In some fruits such as guava, there is a steady decrease in vitamin C as the fruit ripens. [13] This is mainly as a result of the general decrease in acid content that occurs when a fruit ripens. [9]

The salt rub is then rinsed off and discarded before ...
Low-acid foods, such as vegetables and meats, require pressure canning. Food preserved by canning or bottling is at immediate risk of spoilage once the can or bottle has been opened. Lack of quality control in the canning process may allow ingress of water or micro-organisms.
