Swiss novasina water activity meter gives a national solution to help you quickly and easily detect the water activity in the drug to ensure good quality and stable production.

Water activity - an indicator that is not widely known and recognized, but provides more effective information about quality control than traditional moisture content measurements. She is a key parameter on product shelf life, texture, taste and microbial and chemical stability.

A long-lived bakery product such as a cake is a good example. Water activity is a major protective factor. These baked products have a shelf life of about 6 months – between 15 and 27% water. The filling of these products consists of a variety of different sugars, jams and chocolates.

The main protective factor water activity aw value is controlled between 0.7 and 0.8. This is achieved by using different sugars (glucose, sucrose) or polyol (sorbitol). And also by spraying edible ethanol to control the growth of the mold. Through these measures, together with vacuum packaging and other means to prevent bio-corruption.

Take some cakes filled with chocolate filling as an example: water activity (aw) moisture content (%) dough 0.755 23.2 milk caramel mousse 0.785 15.4

The migration of water in multi-component foods is an important factor in the shelf life of foods, and high-temperature baking can balance the water activity between these different components. Therefore, the adjustment of the balance between the different layers of food is not only affected by the baking process, but also by the storage time between production and packaging. Therefore, the indicator of water activity can characterize the stability of microorganisms in baked products. Producing a stable product, the senses of taste and texture are still important, and then monitoring and control should be carried out according to the HACCP regulations in the production process, and the measurement of water activity aw is an important means of such control.
