Food products often have shelf life and expiration dates on their packaging.

  • The concept of shelf life and its difference from expiration date
  • What is the difference between shelf life and warranty period?
  • What to do if you find an expired product

The difference between these two concepts is colossal and the consumer should understand the differences.

Determining the expiration dates of products

The shelf life of food products is a certain period of time during which food products must retain all the organoleptic, physicochemical properties prescribed for this product.

The requirements presented must be appropriate in terms of nutritional value, as well as in the permissible content of substances of a chemical, biological nature, their compounds, and the content of microorganisms harmful to human life and health.

All requirements are presented in established regulatory documents. Requirements also apply to the compliance of indicators of functional purpose.

Requirements of regulatory documents for food product suitability criteria:

  • Organoleptic properties
  • Physicochemical characteristics
  • The nutritional value
  • Permissible content of substances of a chemical, biological nature, their compounds
  • Permissible content of microorganisms dangerous to life
  • Compliance with the functional purpose criteria

The shelf life of food products must be determined in accordance with the requirements.

Consumer actions

A person who discovers that he has purchased low-quality products must file a claim with the seller. The buyer's actions depend on the stage at which it was discovered that the expiration date had expired.

If a violation was identified before acquisition, then the following actions may be taken:

  1. Call the department head or senior manager and point out the discovered position. The person in charge should apologize for the unpleasant situation and immediately take measures to remove the goods from store shelves.
  2. If the staff is unwilling to cooperate, the buyer may request a book of complaints and suggestions, where he can make a record of the incident. Under it, it is necessary to indicate contact information about the person in order to receive feedback and notification of measures taken.

It happens that sellers do not eliminate the shortcomings and do not want to provide a book of complaints, in which case the consumer can purchase a disputed product and contact the supervisory organization with it.

If a delay is detected at home, before or after consumption, a person also has the right to resolve the conflict peacefully by coming to the store or complaining directly to the sanitation station or Rospotrebnadzor.

With the voluntary cooperation of store employees, the buyer must file a claim for the return of a low-quality product that has expired.

Establishing expiration dates for products

The shelf life of food products is determined by a certain time interval: from the date of manufacture to the critical date. During this time interval, the product is considered fit for consumption.

The date of manufacture is considered to be the date of completion of the manufacturing process. The shelf life time interval consists inclusive of storage at the manufacturer's warehouse, transportation time, storage time in stores and after purchase.

The label on which the expiration date of the product is written must include the following items:

  • For particularly perishable food products and products for dietary and baby food: hour, day month, year
  • For perishable products: day, month, year
  • For regular products: month, year
  • Storage conditions rules
  • Rules of use

The expiration date of perishable products does not apply to products whose container integrity was damaged during sales, transportation or at the time of consumption. The expiration date indicated on the label of a product whose storage conditions were not met also does not apply.

The shelf life of products subject to packaging is determined from the date of manufacture of the products, and not from the date of packaging.

Destruction of documents

There is no point in storing documents with an expired shelf life that have lost their relevance and significance for accounting and tax purposes. They must be destroyed. To select documents intended for destruction, organizations annually conduct an examination of the value of documents (clause 2.3.1 of the Basic Rules for the Operation of Organizational Archives).

The examination is carried out by personnel service employees under the guidance of the director of the organization. At the same time, the quality and completeness of the nomenclature of the organization’s files and the correctness of determining the storage periods for files are checked.

The selection of documents is carried out through a sheet-by-sheet review of cases. It is not permitted to select documents for destruction solely on the basis of case titles.

Filing of newly formed cases is carried out only after completion of the examination of the value of the documents. Documents with an expired storage period are included in the act of allocation for destruction of documents not subject to storage. The form of the act is given in Appendix No. 4 to the Basic Rules for the Operation of Organizational Archives.

Documents to be destroyed are entered into the act under general headings indicating the number of cases assigned to this group. The act is signed by the head of the organization. all documents included in the act are either destroyed by the organization itself or sent for disposal. The method of destruction is not regulated. Papers can be burned, shredded, recycled, etc.

The transfer of cases for recycling to a specialized company is issued with an invoice, which indicates the date of transfer, the number of cases to be handed over and the weight of the waste paper. Loading and removal for disposal are carried out under the control of an employee responsible for ensuring the safety of archive documents (clause 2.4.7 of the Basic Rules for the Operation of Organizational Archives).

Shelf life of dairy products

Dairy products are divided into: natural dairy products without additives and preservatives, dairy products, the packaging of which is made using a special technology - vacuum, and dairy products made with the addition of preservatives, substitutes and various additives.

Establishing the shelf life of dairy products is based on full compliance with the law and after testing in an independent laboratory.

The expiration date provides for a small reserve of shelf life for the product to be consumed after the stated expiration date, without loss of quality and safety.

Criteria on which the shelf life of dairy products depends

  • Raw material quality
  • Sanitary and hygienic indicators
  • Process automation
  • Compliance with production technology
  • Type of packaging

The shelf life of dairy products is valid only with mandatory compliance with storage conditions, the transportation process, and the integrity of the packaging. The storage mode for dairy products is indicated on the packaging.

Shelf life of food products is the period of time during which the product retains the properties established in the regulatory and/or technical documentation, subject to the storage conditions specified in the documentation (may not be final).

The shelf life of food products is a limited period of time during which food products must fully comply with the requirements usually imposed on them in terms of organoleptic, physical and chemical indicators, including nutritional value and requirements for the permissible content of chemical substances, biological substances and their compounds , microorganisms and other biological organisms that pose a danger to human health, as well as meeting the criteria for their functional purpose.

Shelf life of non-perishable products

Products with a long shelf life are products that, over a long period of time, without observing temperature conditions, can correspond to their consumer qualities.

Dry products retain their specified shelf life even after the packaging has been damaged.

The storage time for canned food is set from the date of completion of the technological process until the container is opened.

Non-perishable products include these products:

  • Flour and dry flour products
  • Sugar, salt, tea
  • Dried vegetables and fruits
  • Herbs, spices, vinegar
  • Alcohol products
  • Canned food in jars

Preservation of taste and nutritional qualities of non-perishable products is determined by correct storage conditions. Products that do not have an expiration date are not presented in the unified register of food products, indicating their expiration date.

What difficulties may you encounter if you have lost your receipt and the product you purchased is of poor quality or damaged?

What is a technically complex product and how to return it? Read about this and much more here.

Document storage rules

The rules for storing documents are determined by organizations and individual entrepreneurs independently. They are not strictly regulated. As a rule, in small companies, documents are stored in the accounting department in locked safes.

Documents can also be stored electronically. In this case, electronic documents must be certified using an electronic digital signature. This is stated, in particular, in the letter of the Ministry of Finance dated July 24, 2008 No. 03-02-07/1-314.

If the volume of paper document flow does not allow storing documents in the accounting department, a special room is equipped for storage - an archive. At the same time, it is necessary to equip such a room, guided by the Basic Rules for the Operation of Archives of Organizations, approved by the Decision of the Board of Rosarkhiv dated 02/06/2002.

Archives should be located in isolated rooms. The premises must be fire safe, guaranteed against flooding, and have an emergency exit. There should be no gas or water-carrying main pipelines in the premises.

Storing documents in rooms without windows is permitted if there is natural or artificial ventilation in the storage facility.

It is not allowed to store documents in dilapidated, damp, unheated premises that do not meet sanitary and hygienic requirements, as well as premises occupied by public catering services and food warehouses (clause 4.2 of the Basic Rules for the Operation of Organizational Archives).

Documents of permanent, temporary (over 10 years) storage, as well as personnel documents are sent to the organization’s archive. Documents of temporary storage with storage periods of up to 10 years are, as a rule, not subject to transfer to the archive. They are stored in accounting departments and must be destroyed upon expiration of the storage period.

To store a large number of documents, it is possible to enter into paid agreements with third-party archival companies.

How are they different?

The listed terms are an integral characteristic of a particular product. However, in practice they mean different quality parameters. Namely:

  1. Service is the use of products for their intended purpose. For a certain time, the manufacturer is responsible for the quality of the products sold to the buyer. The latter is obliged to comply with the operating parameters brought to his attention.
  2. Suitability is the product’s compliance with safe consumption standards. After the period has expired, the sale of the product and its use are prohibited.
  3. Warranty is an obligation to eliminate product defects within a certain time. The manufacturer takes it upon himself on his own initiative (not established by law).

Attention: for some types of products, service dates are set depending on the season. For example, the countdown for winter boots starts with the onset of the cold period.

Differences

The difference between the warranty period and the expiration date is characterized by the following provisions:

  • GS refers to the entire line of goods sold by food trading enterprises, SG refers to food products;
  • the end of the SG determines that the product has become dangerous and cannot be used for its intended purpose, but the SG - the buyer is only informed about the end of the manufacturer’s responsibility for the product;
  • the GS period is set by the manufacturer or the enterprise selling the product, while the SG is only the manufacturer;
  • The sale of products is prohibited if the SG is not defined, but it is on the list of goods that are necessarily limited in terms of shelf life.

The difference between shelf life and shelf life can be seen using the example of one of the most common healthy products - honey. The entire population of the country probably knows what honey is.

The regulatory acts of its SG are defined as 12 months. During this period, it has little changing consistency, density and taste. At the end of the SG, processes begin to occur that change the external characteristics and taste of the product. At the same time, it does not cease to be of high quality, and can also be eaten. Even with changed characteristics, it can be stored further, maintaining its beneficial properties. Thus, for certain types of products, GS and SG do not have equal importance.
