Sugar leaven is a kind of koji that is suitable for fermentation of sugary raw materials. It is mainly composed of yeast and the nutrients required by yeast. It is suitable for vinegar, molasses alcohol, cider, orange wine, wine and other fields. It is widely used in Brazil, Vietnam, Russia and other places.

  • Advantages of angel sugar leaven

The nutrients contained in the raw materials directly affect the level of alcohol productivity. Hydrolyzed sugar, refined sugar, fruit juice and other raw materials are not rich in nutrients which lack of nitrogen, phosphorus or other trace elements required for yeast growth, resulting in problems such as slow fermentation, low alcohol yield and incomplete fermentation. Sugar leaven contains various nutrients needed for yeast growth, which can effectively solve these problems, improve the yield of wine and reduce the residual sugar content. The yeast contained in sugar leaven is carefully selected, which with good tolerance, high fermentation activity, good preservation, etc. What's more, the formula of sugar leaven is scientific, the product quality is stable, the operation is simple, and has good security because of all materials are food-grade.


  • What to pay attention to during application?

As we all know that the yeast is the only worker in fermentation system, so we should give it a comfortable environment to work. Temperature and pH are very important for yeast fermentation, too high or too low will inhibit yeast activity and cause problems such as low alcohol yield and high residual sugar. on the other side , too high temperature will be suitable for some bacteria, it will be a big potential danger for all the system.Therefore, I recommend controlling the temperature of the fermentation system 28-33 ℃, ph4-6. The sugar content of the raw material should not exceed 270g/L, because excessive sugar concentration will also inhibit yeast activity.


Angel yeast company has developed different types of sugar leaven according to the needs of different processes, such as those suitable for high-concentration fermentation, for low-concentration fermentation and for molasses alcohol fermentation.
