Applications of Perten analyzers in starch production

Functional testing

Native starch pasting quality is readily assessed in the RVA using the 13 minute Standard 1 profile. Pasting tests have been reported using the RVA to characterize maize, potato, wheat, tapioca and other unmodified starches.

Native starches lack the versatility to function adequately in a diverse range of products, so starch is commonly modified to create starches that are better suited for specific applications. Modified starches are used in a range of applications, including mining, paper making, textile weaving, adhesive manufacturing and numerous processed food applications such as confectionary, dairy products, bakery and extruded products, batters and breadings, fillings and frostings, meat and surimi products, sauces, gravies, soups, dressings and beverages. The diversity of the modern food industry and the enormous variety of food products require that starch be able to tolerate a wide range of processing techniques as well as various distribution, storage and final preparation conditions. Modified starches may be readily assessed using the RVA to differentiate starches with different degrees of modification and check whether they are within specification for their intended use.

RVA methods exist for routine characterization of chemically and physically modified starches, including pregelatinized starches.

Compositional testing

Moisture and starch contents of raw materials determine their starch production potential. Monitoring process intermediates helps you optimize and improve efficiency.
