Having the quality problem of the ketchup aseptic bag?

A: tomato sauce of the main causes of aseptic bag bulge bag main source can be divided into two, one is: tomato sauce sterilization is not completely in the production process, under the right conditions, microbial recovery activity, continue to produce acid gas in tomato sauce, lead to bulge bag. Sterilizing thoroughly the key reason point: 1, the sterilization temperature is not enough, not effective sterilization 2, sterilization system of pipeline airtight is lax, sterile environment is not sealed, lead to open dye bacteria with the outside world and the other is: aseptic bag, aseptic packaging is damaged because of asepsis, ketchup microorganisms grow after long-term storage, thus bulge bag. Ketchup aseptic bag of aseptic environment destruction reasons: 1, sterile mouth cover sealing 2, sterile bag of the barrier property of material, breathable waterproof performance of block 3, the uniformity of radiation sterilization process, thoroughness, 4 other external force, such as steel barrels of burr, cause aseptic bag body piercing, task of torn bags, flat 2: the bulge bag reason screening method in actual business 1: bulge bag filling time if occurs within one week after continuity, bulk expansion pack, please get the sterilization temperature, and equipment with or without leaking sauce not sealing pipe 2: bulge bag quantity if bulge bag quantity is something else, no coherence between each batch, is trying to have the lid loosen aseptic bag? Prick the bag body? After long-distance transportation, whether to have and steel barrel sandwiched between the ground breaking? Before and after filling the whole batch or continuous batch produce bulk expansion pack, usually due to inadequate production of sterilization are: in foreign trade business in addition to the expansion pack customer complaint, another more attenuation (customer complaint is colour and lustre Don't discuss here a special case of the malicious false modifications) 。 The reason is: 1, store environment: tomato paste filling, poor storage conditions, such as the sun in the external environment, lead to products in high temperature for a long time, paste Browning speed; Sterile bag type: 2, tomato sauce should be according to the sales cycle length, purchasing aseptic bags with different levels of oxygen barrier. Aseptic bag is often points three block level: aluminum plating basic block, aluminum plating EVOH barrier sterile bag high, pure aluminum foil blocking aseptic bag. Such as aseptic bag of high oxygen transmission rate will result in color difference attenuation fast. A domestic experiments concluded, in outdoor storage more than 12 months of tomato products, from natural chromatism attenuation caused by iron oxide often reaches 0. 13, tons of box can reach 0. 1 - 0. 12. The tomato industry in the competition is becoming more and more incentive, the factory in addition to strengthen the consciousness of the overall quality of the production line workers, production practice and training operators, choice of aseptic bag is also an important lesson!
