2. General Tests (1) The added tests are the Ash and Acid-insoluble Ash Limit Tests, Color Value Test, Inductively Coupled Plasma-Atomic Emission Spectrometry, Microbial Limit Tests, and Specific Rotation Measurement. The Optical Rotation Measurement has been removed.
(2) The amended test are the Arsenic Limit Test, Atomic Absorption Spectrophotometry, Coloring Matter Tests, Coloring Matter Aluminum Lake Tests, Infrared Spectrophotometry, Heavy Metals Limit Test, Lead Limit Test, Specific Gravity Measurement, Viscosity Measurement, and Water Determination.
(3) In Infrared Spectrophotometry, the identification method using a reference spectrum has replaced the method using wave numbers for some additives.
3. Monographs and Storage Standards (1) The relevant parts have been amended in accordance with the revised General Notices and General Tests.
(2) Chemical names and CAS numbers based on IUPAC have been added.
(3) The following additives have been removed or added, because their designation was withdrawn or they were newly designated as approved after the sixth edition was published: Removed Bleaching Powder, Oxyethylene Higher Aliphatic Alcohols, and Polyoxyethylene Higher Aliphatic Alcohols. Added Acesulfame Potassium (effective as of April 25, 2000; appearing only in the English version) Imazalil, Polyvinylpolypyrrolidone, Potassium Gluconate, Sodium Gluconate, Sucralose (effective as of July 30, 1999; appearing only in the English version), and Xylitol.
(4) Major revisions have been made for the following additives: Ester gum, Coloring Matters and Coloring Matter Aluminum Lakes, Polyvinyl Acetate, and Vitamin A Esters of Fatty Acids.
(5) Specifications for some existing food additives have been established. A. Target chemicals (60 chemicals, 3 preparations). Amino Acids (13 chemicals, 3 preparations) L-Alanine, L-Alanine Solution, L-Arginine, L-Asparagine, L-Aspartic Acid, L-Cystine, L-Glutamine, L-Histidine, L-Hydroxyproline, L-Leucine, L-Lysine, L-Lysine Solution, L-Proline, L-Proline Solution, L-Serine, and L-Tyrosine.
Food Colors (18 chemicals) Beet Red, Black Currant Color, CaramelI, CaramelII, CaramelIII, CaramelIV, Carrot Carotene, Carthamus Red, Carthamus Yellow, Chlorophyll, Cochineal Extract, Dunaliella Carotene, Grape Skin Extract, Marigold Color, Monascus Color, Palm Oil Carotene, Paprika Color, and Turmeric Oleoresin.
Thickeners and Stabilizers (13 chemicals) Alginic Acid, Carob Bean Gum, Dammar Resin, Gelan Gum, Guar Gum, Gum Arabic, Gum Ghatti, Karaya Gum, Pectin, Purified Carrageenan, Semirefined Carrageenen, Tragacanth Gum, and Xanthan Gum.
Emulsifiers (one chemical) Quillaia Extract.
Antioxidants (two chemicals) Mixed Tocopherols and d-Tocopherol.
Sweeteners (one chemical) Thaumatin.
Chewing Gum Bases (4 chemcials) Bees Wax, Candelilla Wax, Carnauba Wax, and Shellac.
Enzymes (4 chemicals) Bromelain, Papain, Pepsin, and Trypsin.
Processing Agents (4 chemicals) b-Cyclodextrin, Microcrystalline Cellulose, Powdered Cellulose, and Vegetable Tannin
B. Definitions a. The descriptions of sources and the methods of manufacturing of additives have been based on the List of Existing Food Additives (the Ministry of Health and Welfare Announcement, No. 102, April 1996).
b. Because lactose, dextrin, and fats/oils are normally added to some commercial food additives (such as Chlorophyll and Turmeric Oleoresin) for stabilizing and standardizing, a statement to the effect that the additive usually contains these substances has been added to the definitions.
C. Color Value Color value has been established as a measure for identifying the content of an additive because natural coloring agents include various minor ingredients, besides the major ingredients. The Color Value Test is intended to determine the absorbance at the wavelength of maximum absorption in the visible range for a solution of the food color.
D. Impurities Specifications for impurities including arsenic, lead, heavy metals, and microorganisms have been established.
4. Standards for manufacturing Standards for usable solvents, including the description of substance names and maximum residue limits, have been established for some additives such as spice extracts.
5. Standards for labeling A standard for the labeled content (value) has been added.
