Explain the relationship between food shelf life, shelf life and optimal consumption period.

Food
's
shelf life
is an important factor in determining
seal food safety
and one of the most intuitive basis for judging the shelf life of food safety sales, and is an important measure of
consumers
shopping for food. Therefore, the Food Partners Network collated this interpretation, hoping to help consumers more thoroughly understand the relationship between food shelf life and shelf life.
Suited Food Shelf life:
National Standards for Food Safety
General Principles for Prepackaged Food Labeling
(GB 7718-2011) defines the shelf life of food: refers to the period during which prepackaged food remains of quality under the storage conditions specified in the label. During this period, the product is fully suitable for sale and maintains the special qualities not required or stated in the label. For the shelf life of the explanation, the GB 7718-2011 implementation guide gives the explanation is: the shelf life of prepackaged food is to maintain the quality of food period, accurately speaking, is the best period of consumption, by the producer after scientific verification to determine and through labeling, marking and other means to provide consumers.
The Codex Alimentarius General Standard for Prepackaged Food Labeling (CODEX STAN l-1985, as amended in 2010)
shelf life (best eaten before this date): refers to the deadline for the storage of the food under any prescribed storage conditions. During this time, the product is fully suitable for sale and maintains a necessary or clearly stated quality. However, beyond this date, food may still meet the requirements for consumption.
Interpreted Food Preservation Period: the
Food Partners Network queries past standards and regulations and finds a definition of the preservation period in the defunct General Principles of Prepackaged Food Labeling (GB 7718-2004 standard: the duration of the preservation (recommended last date of consumption, validity): refers to the deadline for the expected preservation period of the food under any specified storage conditions. After this date, the product may no longer have the quality characteristics that consumers expect. And food should not be re-sold. However, this definition and the corresponding provisions have been removed with the revision of the Food Safety Standards Prepackaged Food Labeling General Code (GB 7718-2011). From the point of view of food safety first, the so-called preservation period is no longer publicized.The difference between food shelf life, optimal shelf life and shelf life
The general rules of the National Standard for Food Safety Prepackaged Food Labeling (GB 7718-2011) standard appendix C.4 specify that the label form of shelf life is: ... Before eating (drinking) with the best; Best before; best before this date... The best food (drink) before this date... The shelf life (to) ... The shelf life x x months, etc. It has become clear that shelf life is the concept of optimal shelf life, and there is no interesting difference between these two points. However, in terms of shelf life, the GB 7718-2011 standard eliminates the concept of "preserving period" in GB 7718-2004 because the
Food Safety Law
requires that "food products must not be processed and operated beyond their shelf life".
The shelf life and shelf life are a pair of interrelated and different concepts, the commonalities are to reflect the unity of food attributes and the consistency of the determination process;
Pre-packaged food beyond the shelf life, in a certain period of time still has edible value, but at this time the food safety judgment is entirely up to the consumer to determine, from the legal meaning, if after the shelf life of the harm caused by consumption, its production enterprises and sales operators can shirk their responsibilities. Therefore, food partner network to remind consumers must timely consumption of the corresponding food, more than the shelf life of careful use. At the same time, the important factor that determines the shelf life and shelf life of food is the corresponding storage conditions. Therefore, the Food Partners Network reminds consumers, in the purchase or consumption of food, we must first pay attention to its sales and storage of environmental conditions in line with the corresponding storage conditions.
