With the rise of 'private food customization' in recent years, many people are eager to try and become skilled chefs. Together with the influence of online shopping, they have been crowned with 'pure green food' and 'no added handmade' homemade products. Foods are increasingly favored by 'eating goods' such as homemade yogurt.
Online shopping yogurt needs to be careful Food machinery for you to reveal one or two
Experts in the food industry stated that there are many hidden dangers in either self-made yoghurt or home-made yoghurt. Homemade yoghurt usually does not have bactericidal conditions, and it is prone to breeding of microorganisms, bacteria and other contaminants, which may cause diarrhea, dizziness, and headaches. Nausea and other symptoms can even cause food poisoning.
The author was informed that, in fact, making yogurt is not a simple matter. It is produced through strict process flow, such as batching, homogenization, fermentation, sterilization, cooling, inoculation, filling and sealing, and post-acidification. However, these conditions Are online shopping homemade yogurt or home-made yogurt can not be achieved.
According to relevant personnel, self-produced yoghurt is prone to potential safety hazards in milk sources, strains, fermentation, packaging, sterilization, and later storage. So, is there any way to avoid risks?
First of all, the choice of fermentation equipment. Yogurt production has certain requirements on temperature, humidity, and time, otherwise it is easy to breed bacteria. In general, the fermentation temperature is controlled at 40 °C ~ 45 °C, to ensure a constant temperature, sealed fermentation. The yoghurt machine was used to make yoghurt, but the taste of the yoghurt produced each time was not uniform, and the yoghurt production failed sometimes.
At present, yogurt fermentation equipment appears on the market. It is a fully-enclosed vertical stainless steel structure. The inner wall of the tank is polished with a mirror finish. It is very smooth. The tank has a sandwich, insulation layer, and is equipped with CIP cleaning nozzles, hygienic manholes, mirrors Such devices can not only achieve temperature and temperature controllable, but also can clean and sterilize the equipment. In addition, due to the fully enclosed design to ensure that the logistics is always in a state of pollution-free mixed fermentation.
Second, aseptic packaging material packaging yogurt. Yogurt shelf life is not long, coupled with improper packaging of the product or unreasonable refrigeration, it is easy to breed bacteria. It is understood that Tetra Plysys is committed to aseptic packaging equipment, sterile The research and development of packaging materials, aseptic packaging materials for dairy products, beverages, can protect products from the invasion of light, gas, odor and microorganisms, so that the product does not have to be transported with preservatives, storage does not require refrigeration (yogurt needs refrigerated).
Finally, during the yogurt production process, the sterilization process can not be ignored. On the one hand, raw milk used in homemade yogurt, packaging materials and all utensils, including fermentation containers and mixing utensils, need to be sterilized and disinfected. The CIP cleaning system is often used for cleaning processing equipment. On the one hand, the yoghurt itself wants to be sterilized, and most of them use pasteurization, which is a kind of sterilization method that can kill bacteria and keep the nutrient flavor of the product unchanged with a lower temperature.
In order to ensure that the product during the sterilization process, nutrients, taste is not affected, yogurt cold pasteurization machine came into being. It is understood that pasteurization machine is generally made of stainless steel, stable operation, completely solved the sterilization process Sex, enhance consistency, improve the success rate of sterilization. At the same time, sterilization time and temperature can be set according to the process requirements of food, face sterilization time is too long or too short to affect the bactericidal effect and product taste.
Online shopping yoghurt tends to have simple packaging technology and sterilizing equipment, and the shelf life is short. In addition, most homemade yogurts are difficult to transport cold chain, transport time is long, foods are prone to spoilage, and yogurt quality and safety are difficult to guarantee. Therefore, online shopping self-made Yogurt should be careful.
