Expiration Soon

Expiration Soon(Shomikin) is the limit of the shelf life, that is, the last date and time of the shelf life[1].

The "best-by date" is the period during which the manufacturer guarantees that all qualities such as safety, taste, and flavor are maintained in a predetermined situation while the food products whose quality deteriorates relatively slowly are kept in the packaged state.

Quality is more important than hygiene, so it can be stored hygienically for a relatively long period of time.manufactured foodEnter the "best-by date" in.

After that deadline, you can't eat deliciously.

The best-by date in Japan is2008/(20) February 2Ministry of AgricultureandMinistry of Health, Labor and WelfareNewspaper advertisement by[4] The explanation is as follows.

  • The expiration date is the "expirable date".
  • It shows the expiration date when it is eaten when stored according to the displayed storage method without opening. Let's eat deliciously before the expiration date. However, it does not mean that you cannot eat even after the deadline.

JapanThe expiration date is the Food Labeling Act[5] Food labeling standards that are Cabinet Office Ordinances based on Article 4, Paragraph 1[6] In Article 2, Paragraph 1, Item 8,It means the date when it is recognized that all expected quality can be sufficiently retained when stored by the prescribed method. However, even if the deadline is exceeded, these qualities may be maintained. Is defined asFoodAs mentioned above, it is the deadline for maintaining the required hygiene safety and functions such as taste and flavor.

Basically, it is displayed by date, butcanning,Retort foodな どLong-term storageIt is also possible to display by the year and month if it is possible (3 months or more). In addition,sugar,saltSuch asseasoning,Chewing gum,ice creamExpiration date can be omitted for foods with extremely little quality deterioration such as ice and ice.[7].

These are mainly due to food hygiene considerations, but depending on the storage location and condition, the quality may deteriorate to the extent that they are not suitable for eating and drinking even within the same period.On the contrary, there may be no problem in safety even after a longer period.At the discretion of the individual consumer, the product may be used after the expiration date, but it may also be harmful to health.In the event of health damage caused by using food that has expired or expired, we cannot take responsibility if the manufacturer has no fault.In addition, there are no legal penalties for selling products whose expiration date has expired.

Further, this deadline is a deadline in the case of being stored in a prescribed state in a packaged state. So in the following situationsFresh produceSimilarly to the above, it is necessary to store in a state where the quality preservation condition is better (for example, in the refrigerator as opposed to the room) and then quickly consume.

  • When opening the packaging
  • When placed in a place higher than the prescribed temperature
  • When the state of being maintained changes (eg, when frozen foods have once melted)

Consumer Affairs AgencyIs a nickname / common name for the expiration date, "Delicious guide", And2021/(Reiwa3 years) We have been conducting public awareness since February 2st.[8].

Background to establishing the expiration date

In the past, Japanese processed foods were required by the Food Sanitation Law and the JAS Law to indicate the packaging date of foods as the date of manufacture for all foods, but foods that can be stored for a long period of time are omitted. It was possible.However, regarding the expiration date,Ministry of AgricultureAccording to the JAS law under its jurisdiction, some foods are required to be listed, and although it is not a legal regulation, it is labeled as ○ days after manufacture by the manufacturer.

またmilkAfter sterilization, it is aseptically filled and can be stored at room temperature (room temperature) for a long timeLong life milkWhen (so-called LL milk) is madeMinistry of Health and WelfareIn the Ordinance of the Ministry of Milk, etc. of the Food Sanitation Law under its jurisdiction, dairy companies are obliged to display the quality retention period.

However, the date of manufacture display also showed opposition from the consumer side from the following points.

  1. Foods that are unclear when they should be manufactured (due to date of manufacture)Natto-Kimchi-Yogurt-cheese・AgingSomen Noodles-pickles-canning)The presence of
    Fermented foodIn the case of, since the fermentation progresses even after filling the container and lining up in the store, depending on the product, several dates are attached to the product, such as the filling date, the time to eat, the time when the fermentation proceeds too much and the taste is lost. It was Especially in the case of natto, just at the storeNatto bacteriaIt was shipped back from transportation time so that it would be time to change boiled beans to natto.
  2. FoodGlobalizationWith the progress of (international food distribution), the description of the expiration date is generally received from various foreign countries.Non-tariff barriersIt was pointed out that
    While there was a sense of repulsion against external pressure,Food additiveAwareness that it is difficult to distinguish between products that are easy to maintain freshness and have a long expiration date because they are used, and products that have a short expiration date because they do not contain such food additives. There was also.
  3. Existence of late-night operations on the manufacturing company side, especially milk production
    Day zero (DAY0,D-0) Called a problem.The production process will be moved at midnight when the date changes so that consumers can purchase only the food manufactured and shipped on the same day.supermarketStrongly requested.Due to late-night work, the burden on employees is heavy.

In response to such problems,1995/In 7, the expiration date was displayed.

In addition, since there is still a need for the consumer to describe the manufacturing date,Co-opAnd somePrivate brandSome products still have the date of manufacture added.

In the first place, the best-by date is based on the Food Sanitation Law unified in 05, but it was changed to the food labeling standard in 2015, but it is up to each food company to decide the best-by date. At present, it is generally decided after performing the following three inspections.

  • Microbial examination to check the reproduction of bacteria.
  • Physicochemical examination to check for turbidity, stickiness, color and oxidation.
  • Evaluate the texture, taste, smell etc. that you actually triedsensory test.

Food loss problems and countermeasures

It has been pointed out that if the shelf life and expiration date are shorter than necessary, they will contribute to the mass disposal of food. According to a survey conducted by the Ministry of Agriculture, Forestry and Fisheries, the annual amount of food waste generated in fiscal 2007 was 1,134 million tons.

In the Japanese food industry, there is a business practice called "one-third rule" that divides the period until the expiration date at the distribution stage.[9].. According to a research conducted by the Research Institute of Distribution Economics, the amount of merchandise returned from wholesalers to manufacturers amounted to 2010 billion yen in FY1,139.[10].

Until now, there was no clear standard for the expiration date, and it was up to each food manufacturer to decide,Consumer Affairs AgencyDecided to set a unified guideline on how to set the expiration date for each food. In September 2011, Consumer Affairs Agency Food Labeling Division announced that it will launch a study group with food manufacturers and experts.[11].. From the end of the same month to the following year, the food labeling unification study meeting was held many times.[12].

2014/After reviewing the safety aspect of cup noodles for 5 months → 6 months, bag noodles for 6 months → 8 months, and other beverages, we also saw the movement of each manufacturer to extend the shelf life. To be[13].

This is a delimiter in the sense of whether it is suitable for consumption or not, because after the deadline, the safety as food cannot be secured before the flavor. This difference is expressed by this expiry date for food products that show rapid deterioration in quality within approximately 5 days including the manufacturing date.

Apart from this, according to the Food Sanitation Act,Quality retention period", but the "Act on Standardization of Agricultural and Forest Products and Adequate Quality Labeling" (common nameJAS method) Since the expiration date is almost the same as the expiration date above,Vertically divided administrationAs a harmful effect of, there are 3 kinds of deadlines in food,consumerJurisdiction over JAS lawMinistry of AgricultureAnd the Food Sanitation LawMinistry of Health, Labor and WelfareBy the joint ministerial meeting2003/(15)May 2, It was decided to abolish the quality retention term notation and integrate it into the expiration date notation.

This state change is a state change that is constantly progressing to some extent depending on the storage condition even within the expiration date, and if the expiration date is too large, the following problems will become noticeable, but if the storage condition is poor, the expiration date will be noticeable. It is also a condition that can occur within.The Ministry of Agriculture, Forestry and FisheriesGarbage problem"It doesn't mean that you can't eat immediately after the deadline," he said.[14].

Also, the package is impermeable to moisturePlasticIn the case of a bag made of varieties, the evaporated water recrystallizes in the package and freezes, and is partially soaked in water to reduce the flavor after thawing.
If the storage condition is not good and the food is thawed and then re-frozen, ice particles will be generated in the food.When thawed for consumption, water is removed from it and it becomes uncomfortable.Also, if it rots while it is melting, it will be re-frozen in the rot state.Food poisoningIt also causes.
