Vitamin C extraction: From fermentation to finished product, the key role of steam generators
Recently, topics like " Tomatoes contain less than half the vitamin C of Chinese cabbage " and " Eating vitamin C won't make you whiter " have sparked heated debate, putting vitamin C back in the spotlight. But do you know how vitamin C is extracted industrially? Today, let's take a look at how vitamin C is "created" with the help of a steam generator .
During fermentation broth preparation, a steam generator first sterilizes the raw materials. Raw materials like glucose solution require high-temperature sterilization (around 121°C). Steam flows through a heat exchanger to heat the raw materials, rapidly killing bacteria and creating a sterile fermentation environment for the strain. During fermentation, the strain requires a stable temperature (around 30°C). Subsequently, a jacket and other tools are used to control the temperature of the fermentation tank, ensuring bacterial metabolism and promoting the production of the vitamin C precursor (2-keto-L-gulonic acid).
During the filtration and conversion stages, the steam generator also operates actively. Preheating the filtration equipment with steam prevents impurities from precipitating from the fermentation broth and clogging the filter media due to low temperatures, thereby improving filtration efficiency. The conversion reaction requires a specific temperature (50-60°C), and steam is supplied through a heat exchanger to control the reaction temperature and accelerate the conversion of the precursor to vitamin C.
During the concentration and drying process, a steam generator evaporates water from the vitamin C solution at low temperatures, increasing its concentration and preparing for crystallization. A heat exchanger then provides heat to the drying oven, removing water from the crystals at temperatures below 60°C. This also prevents vitamin C from decomposing at high temperatures, ensuring product stability.
From raw material sterilization and fermentation temperature control to concentration and drying and equipment cleaning, the steam generator provides a stable heat source throughout the entire vitamin C extraction process, silently supporting each step of the process, allowing industrially extracted vitamin C to be produced efficiently and stably, bringing us health benefits. Next time you pay attention to vitamin C, you might as well think about the "contribution" of the steam generator behind it.
