1-DNJ closely resembles glucose in structure. In the small intestine it inhibits α-glucosidase, slowing the hydrolysis of disaccharides and lowering the glycaemic index of the food. Any carbohydrate-containing carrier can therefore take it — the main reason it appears in coffee, dairy drinks, plant milk, milk powder and pressed tablets alike.
Most mulberry leaf extracts are hazy in liquid systems and carry a distinct grassy note. Dissolution speed, clarity and flavour are therefore the three indicators that decide whether an extract can be used in a drink.
Chinese herbal extraction has a long tradition and history of use with water as the solvent; a water-based process for mulberry leaf extract falls within the scope of recognised traditional processing in China. For export customers this means a simpler solvent-residue file and a clearer process narrative.

Kimura T. et al., J Agric Food Chem 2007;55:5869In type 2 diabetic and control subjects the rise in blood glucose after 75 g sucrose was smaller, while breath hydrogen rose — meaning part of the sucrose was not broken down and absorbed in the small intestine but passed to the colon for bacterial fermentation, independent evidence that sugar digestion was slowed
