Chemicals & Foods Food Preservatives


This special technology, based on our pharmaceutical production technology (software), powderizes ethyl alcohol and fills small packets with this using a special wrapping paper. Alcohol gas gradually transpires from the powdered alcohol that fills these small packets to prevent the growth of microbes that cling to food and prevent the formation of mold, etc. Using miniscule amounts of ethyl alcohol to preserve the quality of food, these are extremely safe food quality preservation agents.


Preserves the quality of food by suitably controlling the speed of transpiration of ethanol in the packets.


The action of the ethanol prevents the formation of mold.
In addition, the action of the ethanol preserves the moist feel of foods by keep moisture in.


The ethanol is absorbed into silica gel and small packets made of special film are filled with this. The wrapping materials and contents use safe materials and have no effect on the human body.

The safety of the contents has been verified through acute toxicity tests done by Japan Food Research Laboratories. The wrapping materials have complied with the Ministry of Health, Labour and Welfare Notification No. 370.

Grade selection method for inclusion in product packaging bag

  1. Measure the weight and water activity (Aw value) of the food in question.
  2. Check the estimated suitable amount of Anti-mold Mild from graph on the right.

    150g of sponge cake with a water activity value (Aw value) of 0.84

    The estimated suitable amount for 100g with an Aw of 0.84 is grade 10 Anti-mold Mild.

    In this case, as the foodstuff weighs 150g, it will require grade 15.

  3. Estimat suitable amount of Anti-mold Mild, and then conduct food preservation tests and check quality preservation effects.


* Actual product configuration tests must be conducted to check the effects of Anti-mold Mild.
* Possible food preservation periods are affected by wrapping methods, season of manufacture, environment and storage temperature, even for the same food.
