Chemicals & Foods Food Preservatives
Negamold® Natural (NL) and Negamold® Light (LT) make up our Negamold® product line-up introducing new quality preservation agents with the features of preserving the moist feeling and softness of food in addition to functioning to prevent the growth of microbes and to prevent oxidation. We have two kinds of product in our line-up, Natural (NL) and Light (LT) which correspond to different alcohol quantities so it is possible to select the optimum type for the product in question.
Features
Function
Preserves the quality of food by suitably controlling the speed of transpiration of ethanol in the packets along with absorbing oxygen.
Effects
- Controls the growth of mold
- Prevents the oxidization of food, etc. Preserves the moist feel and softness of food
Recommended use water activity value (Aw) … 0.60 - 0.90
Time required for deoxygenation … 1 - 2 days(25℃)
Safety
he ethanol is absorbed into silica gel and the powder mixed with iron powder, then small packets made of special film are filled with this.
The wrapping materials and contents use completely 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 passed the Ministry of Health, Labour and Welfare Notification No. 370 test.
Product packaging size
We have Single wrapping type and roll wrapping type.

Grade selection method
Please use oxygen transmittance: less than 200ml/m²/day/MPa and ethanol transmittance: less than 10g/m²/day (40℃).
- Method to estimate oxygen quantities inside food package -
The air contains around 20% oxygen. Calculate the amount of air inside the packaging and multiply it by 0.2 to calculate the amount of oxygen inside the package.
Oxygen inside package = (capacity of packaging interior – food volume) × 0.2
< E.g. >
Length Width Height Food volume
{(10cm × 10cm × 15cm) - 560ml ｝ × 0.2 ＝ 188ml
->Therefore, the appropriate product is Negamold Natural/Light grade 200
Possible food preservation periods are affected by packagingwrapping methods, season of manufacture, environment and storage temperature, even for the same food.
Instructions (for consumers using the product)
[ Single packet type ]
- Please use within 15 minutes of opening (25℃)
- There are notches (slits) on each package so please use these to open the packages.
Please note that the packages are filled with small bags up to the notches so be careful not to rip any of the bags.
[ Continuous packets Type ]
- Please use within 3 hours of opening (25℃)
- The start is clearly written on a sticker on the external packaging. Please use from the start after opening.
[ Common Points for Single packet type and continuous packets Type ]
- Please use materials through which it is difficult for oxygen to pass (oxygen transmittance of less than 200ml/m²/24hr/MPa) with low alcohol transmittance in product packaging (less than 10g/m²/24hr (40℃)).
- If using one packet in assembled packages, please make holes in the individual packaging (around 8 holes of 3mm per 100cm² of packaging)
- Please do not use knives or blades when opening cardboard boxes. Use of such implements could damage the products inside.
- Please do not use the product if the external packaging is blown before it is taken out of the box and is still intact as there is the possibility of defective pinholes or stickers (they are usually deaerated).
- If you are not going to use all of them, please make sure there is as little air as possible in the external packaging and store them after heat sealing. It is possible to store them with a clip for short periods of time such as break times.
[ Others ]
- The Negamold Natural/Light deoxygenation rate becomes slower the lower the temperature becomes and is extremely slow at 5℃ and under.
- When using Negamold Natural/Light and inert gas together, please avoid the use of carbon dioxide.
- When using with vacuum packaging, Negamold Natural/Light may stick to the food and the wrapping film and deoxygenation and ethanol transpiration may not be possible. Please conduct light deaeration to the degree that air can circulate within the packaging.
Please read the user’s manual for other details.
Instructions (for general consumers)
Negamold Natural/Light is enclosed in food packaging in order to preserve the good taste of food and allow consumers to eat food safely.
