In food production they have quality assurance labs. Batches of products are tested for acidity, brix (sweetness), color, consistency, etc. There is an acceptable range for all tests. If a product falls out of range, adjustments are made to that batch. Those codes on packaging can provide information for what precise batch it came from. This is also very critical in the event a food product must be recalled.
