Snowy moon cake fashion, good-looking and delicious, but there are certain security risks behind the delicious. Recently, the Food and Drug Administration of a certain place issued a notice saying that more than 150 batches of cakes were sampled, and three batches of unqualified products were snowy moon cakes. The reason is that the mold is seriously exceeding the standard. Then, the author analyzes from the process, and how to use the purification equipment, CIP cleaning system, cold chain equipment to ensure the safety of Mid-Autumn Snowy Mooncake!
The author understands that because the production process of snowy moon cake is very special, it is a cold-processed pastry product, which is more susceptible to microbial contamination than traditional moon cake. In general, the production of snowy moon cake includes raw material pretreatment, battering, steaming, cooling, Suede, stuffing, compression molding, molding, packaging, cryogenic refrigeration, transportation and many other processes. Because most traditional moon cakes need to be baked, and snowy moon cakes are not.
In fact, the traditional moon cakes use the baking process, which can effectively kill the microorganisms under high temperature conditions, ensure the quality of the moon cakes, and at the same time, the high temperature baking moon cakes have lower moisture, which is good for inhibiting microbial growth and further reproduction. Without high temperature sterilization, after a series of processing procedures, it will inevitably be endogenous and exogenous, causing mold to exceed the standard, short shelf life, perishable and deteriorating, affecting food safety.
Undoubtedly, the production process of snowy moon cake can not be changed, but it can be equipped with professional processing equipment to ensure the safety of production. Experts in the industry said that in addition to the processing technology, there may be other three aspects. Reasons: First, raw materials or packaging materials are contaminated by mold; second, the environmental hygiene conditions of product processing are not controlled; third, production equipment, facilities are not cleaned and disinfected, product preservation, improper transportation conditions, etc.
Then, how can the snowy moon cake that does not pass the high-temperature baking sterilization process avoid breeding microorganisms, leading to excessive mold? First, the transportation and storage of raw materials will increase the chance of microbial contamination to a certain extent, and the raw materials should be inhibited or sterilized. Choose high-quality and safe raw materials for production. At the same time, because the packaging materials are directly or indirectly in contact with moon cakes, it is especially important to ensure the safety, hygiene and pollution of the materials (need to be disinfected and sterilized in the packaging materials, and half of the ultraviolet lamps) More than an hour).
Secondly, compared with other food and beverage production and processing, cakes such as snowy moon cakes have very high requirements on the sanitary conditions of the processing workshop. In addition to mosquito killing lamps, ultraviolet lamps and no water on the ground, no debris is piled up, and winds need to be installed. Leaching system, dynamic air disinfection machine, cleaning and disinfection room, etc., not only can remove the dust, hair and other pollutants carried in and out of the personnel, avoid cross-infection, and can also purify the air in the workshop, after secondary sterilization, filtration treatment Clean air is in an uninterrupted circulation, keeping the environment of the mooncake workshop in a relatively 'sterile, dust-free' sanitary condition.
Finally, the production of snowy moon cakes involves many processing equipment, such as mixing tanks, cooking equipment, leather making machines, stuffing machines, molds, etc., especially the direct contact equipment is not cleaned and disinfected, causing the second microbial contamination of moon cakes. At present, the CIP automatic cleaning system on the market is often used for the cleaning and sterilization of various food processing equipment and facilities. It can effectively clean the tank containers and pipes in place, not only ensuring the integrity of food equipment and Reduce the maintenance rate of the equipment, and achieve the purpose of thorough cleaning and disinfection.
As mentioned above, in terms of process, snowy moon cakes are more likely to breed microorganisms than traditional moon cakes. If the purification equipment, CIP cleaning system and other installation applications ensure the production of mooncakes in the processing workshop is safe, if the whole process of cold chain transportation is not ensured (Cryogenic storage), there may be a risk of microbial contamination. It can be seen that from the purification of the processing workshop, the cleaning of food equipment to the whole process of cold chain transportation, the role of related food processing equipment should not be underestimated in ensuring the safety of moon cake production!
