GB 8950-2016National food safety standard - Hygienic specifications of cannery (English PDF)

2.1 commercial aseptic

a state that the food, after a moderate heat sterilization, does not contain

pathogenic microorganisms, does not contain non-pathogenic microorganism

that can reproduce therein at normal temperature

2.2 sterilization procedures

technical parameters and operational requirements for thermal sterilization

that can make the product meet the commercial aseptic requirements under a

certain production conditions

2.3 residual chlorine (free residual chlorine)

chloride remaining in water in the form of hypochlorous acid, hypochlorite or

chloride ion

2.4 sterilization deviation

any phenomenon that fails to meet the heat sterilization process during the

heat sterilization process

2.5 key factors of thermal sterilization

the nature, characteristics, conditions, form or other parameters affecting the

heat transfer; when these factors change slightly, it shall directly affect the

mg/L. The cooling method is the internal circulation without chlorination.

5.4 Ventilation and temperature control devices

5.4.1 The canned food processing workshop shall be installed with

ventilation equipment so as to keep the air circulation in the workshop. The

process link that produces a lot of steam or fumes during the production

process shall be relatively concentrated. Use a well-ventilated equipment or

other effective handling measures to discharge it from the workshop. The

vent shall be fitted with a corrosion-resistant net cover and kept clean.

5.4.2 Based on different product processing temperature requirements, the

temperature control equipment shall be installed in the canned food

processing workshop.

5.5 Sterilization equipment

5.5.1 Sterilization equipment shall meet the requirements of sterilization

process. Sterilization pot shall be consistent with the provisions of the state

pressure vessel standards.

5.5.2 After sterilization equipment is installed, it shall carry out the thermal

distribution test. it shall be put into use after the thermal distribution is

confirmed uniform. When the heat supply and heat transfer medium are

guaranteed, it shall perform thermal distribution test at least once every three

years. If there is change in this equipment's structure, pipes, valves,

procedures and when necessary, it shall re-perform the thermal distribution

test.

5.5.3 Sterilization ancillary facilities

5.5.3.1 Temperature indicating device

Each sterilization device shall at least install one mercury thermometer or

other temperature indicating device to determine the sterilization reference

temperature.

Mercury thermometer shall meet at least. minimum scale of 0.5°C, scale

range per centimeter does not exceed 4°C; the mercury thermometer shall

send the legal organization of measurement once a year for verification. It

shall be affixed with a label having record date, validity, inspector, etc.

5.5.3.2 Temperature and time recording device

Each sterilization device shall be equipped with a temperature-time recording

device. The temperature recorded during sterilization shall be equal to or less

than the sterilization reference temperature, not greater than the reference

temperature. If there is any deviation, it shall be recorded. The automatic

8.5.3.1 The enterprise shall develop bactericidal safety assessment and

management procedures, put forward various types of product correction

program.

8.5.3.2 Sterilization deviation treatment

Once deviation is found in the sterilization process, it shall be immediately

reported to the technical person in charge of the enterprise. Correct it

according to the correction solution. Isolate the product. Find out the reason

and put forward corrective measures.

For isolated products, the assessment shall be carried out on the batch of

products whether they are harmful to the health of consumers. If it is

determined that the batch has not met the requirements for commercial

aseptic, it shall be completely sterilized or properly handled under strict

supervision. The use of the determination process, the results and processing

methods shall be recorded in detail.

12.1 In accordance with relevant provisions of Clause 12 in GB

14881-2013.

12.2 Sealing operators, bactericidal operators and inspectors shall be

trained in technical training.
