Table 2 also provides some data on the resulting product in the
form of proximate composition and the actual water content of the
products. These are predicted values based on the dry ingredients
and the moisture content of the product as it exited from the
extruder. It can be seen that the extruded product has a protein
content in the range 40e60 g/100 g (dry basis); carbohydrate in
range 31e65 g/100 g (dry basis) and moisture content in the
range 22e35 g/100 g (wet basis). While they provide a protein
and carbohydrate rich product, the extruded product is also too
high in moisture content to provide adequate stability. The water
activity in most cases was higher than 0.85 and hence the drying of
extruded product for few hours was necessary to produce a low
moisture shelf stable product.
