Interpretation: The instruction “Refrigerate after opening” appear on the label to be inferred.
Concept Introduction: The color, flavor, and texture of foods are traditionally preserved through refrigeration. Fruits are generally sugar-based fruit preserves that are thickened or partially jellied.
Answer to Problem 107A
The instruction “Refrigerate after opening” appear on the label to preserve the jam for a longer period free of microorganisms.
Explanation of Solution
Jars of jam are stored on grocery shelves at room temperature because the container is sealed and it is airtight packed so there is no growth of bacteria.
But when once the seal is opened, the jar is prone to microorganisms.
To avoid the growth of microorganisms, the jars are kept in refrigeration.
Refrigeration is just one of many distinct elements or barriers, that can be employed to reduce the risk of microorganisms.
Lowering the storage temperature slows these microorganisms' rate of development.
Mold and bacterial development almost immediately resume at room temperature, and greater temperatures can trigger an explosion of growth that quickly deteriorates the food product.
