Article 19-1
(4) Oil nature inspection equipment (moisture content, acid value, peroxide value, iodine value, etc.)
The basic facilities and the production and inspection equipment of the operating site of a food additive factory should meet the following requirements:
1. Basic facilities:
(1)Warehouse: The warehouse should have segregated sections classified according to the properties of the raw materials, semi-products and end products for storage; moreover, where circumstances shall require, the warehouse should be equipped with the refrigerator (freezer).
(2) Design of machinery and equipment: The design and structure of the machinery and equipment used for production of food additives should prevent hazards from deteriorating the quality and hygiene of food additives and should permit easy cleaning, sterilization and inspection. Moreover, the structural design should safeguard products against contamination of lubricants, metal filings, wastewater, or other contaminants. The equipment designed for solvent extraction or powder production should be equipped with appropriate safeguards to avoid hazardous substance leakage or dust explosion.
(3)Materials of machinery and equipment:
The equipment and utensils used in the food additive processing section or likely to have contact with food additives should be made of materials incapable of producing or dissolving and generating toxins and bad or unpleasant odors; moreover, materials should be non-absorbent and corrosion-resistant and capable of withstanding repeated washing and sterilization procedures. The use of materials which produce contact corrosion shall also be avoided.
2.Production equipment: A food additive factory should be equipped with the following production equipment:
(1) crusher;
(2) screening machine;
(3) mixer;
(4) dryer or oven;
(5) mist sprayer, air blower, and drying equipment;
(6) powder collection and processing equipment;
(7) stirring and blending equipment;
(8) filtering equipment;
(9) heating reactors;
(10) concentration equipment;
(11) electrolysis device;
(12) dissolving equipment;
(13) storage device;
(14) filling equipment.
3.Inspection equipment: A food additive factory should be equipped with the following inspection equipment:
(1) glass apparatus for general chemical analysis;
(2) weighing scale (sensitivity below 1 mg);
(3) pH meter;
(4) moisture detector;
(5) additional inspection equipment to be installed upon requirement of procedures:
a. photoelectric colorimeter;
b. gas chromatography;
c. liquid chromatography;
d. spectrophotometer;
e. microbiological testing equipment;
f. hydrometer;
g. atomic absorption spectrophotometer;
h. turbidimeter;
i. electrical conductivity meter;
j. polarimeter;
k. refractometer.
It is imperative that no residues of catalysts, solvents, or chemical substances other than food additives used in the production process are contained in the end product of the final production process.
Where the range of products produced in the operating site of the food additive factory as defined in Paragraph 1 should include food additives, chemical raw materials, and chemical products, the production process or the operating sites and equipment should be effectively segregated or isolated to avert cross-contamination. The term isolation herein refers to the presence of concrete dividers or barriers separating the different operating sites; whereas the term segregation refers to the employment of concrete or intangible measures to segregate facilities through any one or several of the following means:
1. separation of operating sites;
2. separation of production time;
3. airflow direction control;
4. employment of closed systems;
5. other effective meas.
