On May 29, 2023, the Ministry of Health, Labour and Welfare of Japan (MHLW) issued Announcement No. 0529-2 of Raw Food Development, formulating six standards for the detection methods of food additives in food. The specific contents are respectively:

(1) Formulate the standards for the detection methods of three antioxidants including butylated hydroxytoluene (BHT) in vegetable oil and other foods, specifically liquid chromatography, with a detection limit of 0.005 g/kg;

(2) Formulate the detection method standards for 12 kinds of pigments in food, such as edible red No. 2, specifically thin-layer chromatography, with a detection limit of 0.01 g/kg;

(3) Formulate the detection method standards for three sweeteners including o-sulfonylbenzimide in food, specifically UV spectrophotometry, with a detection limit of 0.01 g/kg;

(4) Formulate the standards for the detection methods of two acidity regulators such as disodium edetate in food, specifically liquid chromatography tandem mass spectrometry, with a detection limit of 0.01 g/kg;

(5) Develop a detection method for two pigments including copper chlorophyll in food, specifically atomic absorption spectrometry, with a detection limit of 0.0005 g/kg, etc. This announcement takes effect from the date of publication.
