General principles of inspection and mark,packing,transport,storage for industrial enzymes1 Subject content and scope of application
This standard specifies the inspection rules and requirements for mark,packing,transport and storage of industrial enzymes. This standard applies to various industrial enzymes that have been purified,prepared and packaged for shipment. 2 Inspection rules
2.1 BatchbZxz.net
QB/T1804-1993
Products produced in each shift or each tank and packaged for shipment by the manufacturer with the same process conditions, the same product name, batch number, specifications and the same quality certificate are considered a batch. 2.2 Classification of unqualified items
2.2.1 Class A unqualified items Salmonella, ceran, coliform group, total bacteria count, heavy metals. 2.2.2 Unqualified items for category B: enzyme activity, enzyme activity preservation rate, drying loss, pH value. 2.2.3 Unqualified items for category C: appearance, odor, fine (particle) size, bulk density, net weight (net volume), packaging, labeling. 2.3 Inspection classification
2.3.1 Factory inspection (delivery inspection)
2.3.1.1 Before the product leaves the factory, the quality inspection department of the manufacturer shall conduct batch inspection according to the provisions of this standard and product standards. Only products that pass the inspection and are issued with a quality certificate can leave the factory. 2.3.1, 2 Factory inspection items: appearance, odor, enzyme activity, enzyme activity preservation rate, drying loss, fine (particle) size, pH value, net weight (net volume), packaging, labeling.
2.3.2 Type inspection (routine inspection)
Generally, it is conducted once a quarter. Type inspection is also required in any of the following situations. 2.3.2.1
Change of main raw and auxiliary materials;
Major changes and variations in the process;
When the production is resumed after a long-term suspension
When there is a significant difference between the results of the factory inspection and the last type inspection;
The national quality supervision agency shall conduct random inspections.
2.3.2.2The type inspection items are all technical requirements in the product standards. 2.4 Sampling and determination
2.4.1Appearance, odor, net weight (net volume), packaging and labeling shall be sampled and determined according to Table 1. 2.4.2Other items shall be sampled according to Table 1, analyzed after sufficient mixing, and determined individually. If there are any Class A unqualified items, the whole batch of products shall be judged as unqualified and no re-testing is required. If there are any Class B unqualified items, or if there are two or more Class C unqualified items, double the amount of samples shall be taken from the same batch of products for re-testing, and the re-testing results shall prevail. If there are still Class B unqualified items or if there are two or more Class C unqualified items, the whole batch of products shall be judged as unqualified.
2.4.3 Packaging inspection method For solid dosage form preparations, place the unit small package with the seal facing down and shake it three times. There shall be no leakage. For liquid dosage form enzyme preparations, tighten the sealing plug of the barrel and turn the barrel upside down for 1 minute. There shall be no leakage. Table 1

2.5 The consignee has the right to take samples from the delivered batch of products at the time of delivery and conduct acceptance inspection in accordance with the provisions of this standard and product standards. The vitality index should be inspected and reported within 10 days after receipt. 2.6 If the supply and demand parties have a dispute over the quality of the product, they can negotiate and select an arbitration unit to entrust it with inspection and arbitration, and the cost shall be borne by the losing party.
3 Labeling, packaging, transportation, storage
3.1 The outer packaging of the product must be a cardboard box or plastic barrel lined with food plastic film or moisture-proof paper. The outer packaging should indicate the product name, manufacturer name, factory address, specifications, production date, net weight (net volume) and unit packaging quantity, registered trademark; it should also be accompanied by a quality inspection certificate. 3.2 The inner packaging of the product should use vinyl plastic bags or aluminum foil bags that meet food hygiene requirements, plastic bottles (barrels) and other non-toxic containers. The inner packaging should indicate: product name, manufacturer name, trademark, specifications (enzyme activity), unit packaging net weight, production date (batch number), implementation standard number and grade, storage conditions and shelf life. 3.3 Inner packaging, the specifications of the body enzyme are divided into 0.5, 1.0, and 2.0kg; the liquid enzyme is divided into 0.5, 1.25, and 25L. The shipment is carried out according to the contract between the supply and demand parties. Weight tolerance: Net weight (net volume) not more than 2.0kg (2.0L) tolerance is ±2%, more than 2.0kg (2.0L) tolerance is ±1%. However, the total weight of each box shall not be less than the number marked on the box. 3.4 Enzyme preparations contain biologically active substances and should be prevented from turning over, moisture and sunlight during transportation. They should be handled with care during loading and unloading, and stacked neatly to prevent dumping and heavy pressure.
3.5 During storage and transportation, it is strictly forbidden to mix, store and transport the products with toxic, harmful, corrosive items and other pollutants. 3.6 The products should be stored in a clean, cool, dry and ventilated warehouse, or stored at low temperature (5-10℃) to improve the stability of the enzyme and extend the shelf life.
3.7 The limited date for the preservation rate of the enzyme activity of the product is the minimum shelf life, which is half a year for solid enzymes and three months for liquid enzymes. Each manufacturer can mark it according to the actual situation. After the expiration date, the enzyme activity may decrease, but it can still be used, but the usage amount must be increased accordingly. Additional remarks:
