Researchers at DTU have developed a yogurt bacterium, which might cleave lactose in an economical and sustainable method. This makes it attainable to create pure sweetness in yogurt with much less added sugar.
Yogurt with out added sugar is a comparatively bitter expertise. Typically fruit or berries are added to enhance style, and sugar or sweeteners are added to extend sweetness. Nevertheless, customers are more and more demanding pure meals with much less added sugar.
To fulfill this demand researchers from DTU Nationwide Meals Institute have developed a brand new and pure method to cleave the milk sugar, which depends on protected lactic acid micro organism. The developed lactic acid micro organism create pure sweetness within the yogurt, thus decreasing the necessity for added sugar.
Lactic acid micro organism with lactase can break down milk sugar
Yogurt is fermented milk, and milk naturally accommodates round 50 grams sugar (lactose) per liter. Milk sugar is characterised by its low sweetness, however by breaking down lactose with enzymes, extra candy sugars (glucose and galactose) are launched. By breaking down 70% of the lactose in milk, the sweetness could be elevated what corresponds to twenty grams per liter of standard sugar.
Commercially accessible lactase enzymes at present used for breaking down lactose in milk merchandise, are made utilizing microorganisms, which entails, a tedious and dear purification course of. Moreover, transportation from the producer website to the dairy provides to the prices.
With the answer that the DTU researchers have developed, the lactic acid bacteria-based lactase could be grown and used straight on the dairy, and within the milk that finally ends up being yogurt. On this method the prices for buying the lactase and transportation are lowered,
The answer has been examined by a big Danish dairy, and the examine was printed within the Journal of Agricultural and Meals Chemistry.
