The content of resistant starch in food products may be
increased by supplementing them with special starch preparations
used as an additive to raw material in the technological
process. Those starch preparations with high concentration
of resistant starch are produced with multiple
methods and demonstrate different types of resistant starch.
Food products may be enriched in RS I. It refers most often
to dry cereal products or some types of bakery products.
They are made of (or supplemented with ) whole or partially
desintegrated cereal grain [Stephen 1994]. In such material,
starch - present in the cells with walls undamaged in the
technological process – is inaccessible to amylolytic
enzymes.
