Production method

The contents are washed and the non-edible parts are removed. Depending on the contents, cooking or the like is performed, and the contents are put in a can, and a seasoning liquid is put in some cases. It is sealed when the air inside the can is removed. After this,Clostridium botulinumHeat sterilized to prevent breeding.

In the case of canned fish, it is sterilized under high temperature and high pressure at 120 degrees Celsius for about 1 hour (this process softens the bones of the fish).[12]..

Initially the seal was manuallySolderingBecause of this, we were able to produce only 60 to 70 pieces per person per day.[15]. 1833The French company Ansilbert devised a method to open the can by soldering around the lid of the can and melting it with heat.

At the end of the 19th century, the production of canned food got off the ground,Campbell,HeinzCanned food became a sort of status symbol when quality products that could become an everyday food, such as other soups, began to appear[16].

Japanese canned food

The first production in Japan was in the 4th year of Meiji (1871)NagasakiBy (Matsuda/Gaten)FrancePeopleLeon DuryLeon Dury[17]Under the guidance ofイ ワ シIt is said that a trial production of canned oil was done.[12](At this stage the word canned does not exist).

The start of full-scale production1877(10th year of Meiji)May 10,HokkaidoIshikari cityIt is due to the establishment of the Ishikari Canned House. In the beginningAmericaUlysses S. Treat and Trescott Swert[17]Under the guidance ofsalmonThe cans were manufactured. From this, the Japan Canned Foods AssociationMay 10Is defined as the day of canning. Initially cannedPipe plugWas spelled out.

Meiji EraIs mainly for export to outside Japan and for domesticMunitionsBecause it was produced for commercial use, it did not spread to the common people. At that time, the price of canned food was 1 to 20 yen per can, and 35 rice bowl was 1 yen, so you can see how expensive it was.[18].

The reason for its full-scale spread is1923(12th year of Taisho)Great Kanto EarthquakeIt is attributed to the use of canned food as relief supplies sent from the United States.

As a special example,Second World Warof timeMetal donationThe pottery substitutes developed in response to this include canned foods, and many pottery containers with a lid sealed with rubber were distributed under the name "" at that time. However, due to lack of food itself to be canned, production was eventually discontinued.[19].. It should be noted that there was no problem in the quality of the food inside even if I opened the one that was more than 60 years after the war.[20].

Throughout the Taisho era and Showa era, crab, salmon, and canned goods were exported brilliantly, but in 51 (1976) To 52 (1977The export of these canned foods was devastated by the establishment of the 200-nautical mile fishery exclusive area decided by[21]It became a thing.

Display on canned food

For Japanese canned food

Regarding display, quality display standards andFood Sanitation ActAre subject to regulations such as[23].. In addition to the collective display using labels, etc., a "canned goods name symbol" (Popular name can mark) Etc. are stamped. Originally, the canned goods name code was obligatory to export canned foods overseas under the Export Control Law, but now the legal obligation is abolished with the abolition of the Export Inspection Law in March 9. However, it is often the case that food cans are customarily stamped with the product name symbol. The canned product name symbol indicates the type of raw material and cooking method in the upper row, the expiration date in the middle row, and the manufacturing plant in the lower row. However, since the product name and factory code are listed separately, many can lids have only the expiration date displayed on them.[23].

  • Raw material type name (2 letters combining the XNUMXst and XNUMXnd letters from the top left)
  • Cooked state (in principle, 3 letter from the top left from the 3rd place, but 4 letters combining the 2rd and XNUMXth place letters only in cooked state that does not require distinction of form, size, or added auxiliary materials)
  • Form/Small/Additive supplementary raw material (4st character from the upper left to the 1th place)

  • Expiration date display (display in the middle row)
The middle part of the three-column string isexpiration dateIn the display, "041010" means that the expiration date is October 2004, 10. The date may be omitted and "10" (meaning the expiration date for October 0410) may be displayed.1999(11)May 3Up to the manufacturing date, this display may include the manufacturing date (day). There was also an era in which very old canned foods were represented only by the last digit of the manufacturing year, with October manufacturing as "1", November manufacturing as "Y", and December manufacturing as "Z". (Example: Manufacturing November 10, 0 = "11Y12"). This was because there was a limit to the marking ability of the can making machine.
  • Manufacturing plant (display at bottom)
As a general rule, use a combination of alphabets and Arabic numerals for each company and factory, and apply within XNUMX characters. Since it was an application system, there are symbols of different companies and factories even with the same symbol.

As an inspection method to judge the quality of canned food,sensory testThere are three[24].. However, in order to conclude that it is a defective product, it is necessary to perform an in-laboratory test by an expert.[25].

Visual inspection

When inspecting the appearance, it is necessary to pay attention to the deformation of the winding part first.[24].. If the body hook and cover hook are of the proper length and there is improper tightening such as not being able to secure sufficient overlap, a gap is likely to be created by the impact.[24].. If there is a void in the can, bacteria will enter the inside of the can, regardless of its size.corruptionConnected to[26].. If the contents of a canned food rot, the gas pressure inside the container may increase due to the gas produced by bacteria, and the can may expand.[26].. If there is a fragile part in the winding part, the juice leaks from it and gives off a bad odor.[26].

There are several types of expansion. The protrusion on the bottom of the lid due to insufficient degassing during manufacturingFlipperTo say[27].One side expansion (Springer)Is a phenomenon that one side of the lid bottom protrudes, and the cause is insufficient deaeration and chemical change of the can material and contents.Hydrogen gasIs overfilled[28].. Also, make sure that both sides of the can do not swell.SwellTo say[28].. Expanded cans are treated as defective[26].

Percussion inspection

The percussion inspection is an inspection method that estimates the inside condition from the feel of the pitch, the stain, and the vibration when the can lid is tapped with a percussion rod.[28].. This inspection reveals the generation of gas, the volume of the space above the can (head space) being too large or too small.[29].. Appropriate skill is required for percussion inspection[28].

sensory test

sensory testThen, smell, color, taste, honeycomb (Tuna,salmon,イ ワ シMany small holes are opened in pieces of fish meat such as,honeycombTo look like[30]) Etc.[30].. For seafood cans, odor is the most powerful means[30].. Honeycombs can be seen not only when raw materials with reduced freshness are used, but also when frozen raw materials are used, but in the latter case even if a piece of fish meat is put on the tongue, it does not have an unpleasant taste.[31].. Sensory testing by taste should not be done on anything apparently rotting[30].
