In shortThe Japanese Standards for Food Additives (Shokuhin Tenkabutsu Koteisho) is an official reference, based on the Food Sanitation Act, defining the composition specifications, manufacturing standards, and test methods for food additives approved for use in Japan. It is the benchmark for judging whether a material meets “food-additive grade.”
What it is
Based on the Food Sanitation Act, the Standards compile composition specifications, storage and manufacturing standards, and test methods for designated additives and others. To distribute a material as food-grade, conformance to the latest edition is the premise. Spec sheets commonly state “conforms to the Japanese Standards for Food Additives.”
How to read “spec compliance”
Compliance is confirmed by matching each item on the spec sheet / COA against the standard values. Key items include:
- Assay (purity / potency)
- Description (appearance, color, odor)
- Identification test
- Purity tests (heavy metals, arsenic, related substances)
- Loss on drying / residue on ignition, quantitation
Practical points for sourcing
Confirm conformance with your supplier and back it up with the spec sheet and COA. Note that applicable standards differ by use (food / pharmaceutical / feed). FONTIA’s catalog shows specifications and uses per ingredient; spec sheets are provided individually upon request.
FAQ
Where can I check the Japanese Standards for Food Additives?
They are notified and published by the Ministry of Health, Labour and Welfare. Spec sheets often state conformance to the Standards.
Can I use a substance not listed in the Standards?
It depends on the classification (designated additive, existing additive, etc.). Confirm the use and classification, and consult experts or authorities if needed.
Do food grade and pharmaceutical grade differ?
Yes. Pharmaceutical use follows separate standards such as the Japanese Pharmacopoeia. Confirm spec compliance appropriate to the use.
