An innovative range of cold water swelling potato starches Convenience food must be convincing. And users will only be convinced if the products they prepare are of the very best quality. Selecting the very best ingredients is crucial if the end product is to live up to the standards demanded by discerning consumers. Choosing the appropriate starch is especially important. KMC – the leading Scandinavian producer of potato starch – has developed a new range of cold water swelling potato starches called ColdSwell. These starch products are very suitable for preparing convenience food. Starch an important factor Starches have a significant impact on the quality of the end products in which they are used due to their ability to absorb liquid and add texture. Also the smoothness, shine, taste and mouth feel are influenced by the quality of the starch. It is also important that these instant starches used in typical industrial applications are highly dispersible. Traditionally produced cold water soluble starches have been used for years, but have never been able to provide quite the same good functionality as cook-up starches. The new ColdSwell range differs from traditional drum-dried instant starches, because the starch granules remain intact after spray cooking. Stable viscosity ColdSwell starches are able to bind more liquid in stable suspensions than it has been possible to achieve with cold water soluble starches. This new process ensures both the excellent viscosity and the neutral taste found in potato starch. Drum-dried starches provide a high level of viscosity in the cold stage, but part of this viscosity is lost if they are subsequently heated. ColdSwell provides a high level of viscosity in the cold stage, similar to that of cook-up starches, even after repeated heating. ColdSwell products can therefore be used in productions that require a wide range of different temperatures. Under shear stress conditions, ColdSwell starches gradually absorb more water and thus develop more viscosity, whereas drum-dried starch normally loses its water-binding capacity during shear stress. 
Typical viscosity curves for drum-dried starch, modified cook-up starch and ColdSwell 3681 Less hysteresis Depending on the type and intensity of the modification, spray cooked starches are more stable towards hysteresis than comparable modified drum-dried starches. This results in a much lower tendency to lose viscosity during subsequent stress conditions such as mechanical treatment, low pH and heating. Even after very heavy mechanical treatment of ColdSwell products in industrial production processes, the granular structure of the starch remains largely intact. This results in a better texture and taste/smell quality compared with traditional drum-dried starches. Experience and trials show that ColdSwell starches also are more economical compared with conventional drum-dried starches. Typical applications ColdSwell starches are an interesting alternative to traditional drum-dried instant starches. They combine the technical advantages of cold swelling starches with the best product qualities of cook–up starches. These advantages can be seen in emulsions such as mayonnaise, sauces, spreads and dressings, and various cold preparations like ketchup or fruit paste. They provide benefits in dry mixes such as cup-a-soup products and sauces, which only require limited heating when preparing. Agglomerated ColdSwell versions in particular eliminate the risk of lumps forming in liquids. They also dissolve completely and provide the necessary viscosity in the end product. Stability, neutral taste, and lower dosages are all of major importance for the preparation of baker’s custard and desserts. In its production of ColdSwell products, KMC invested in a modification plant in Brande, Denmark. This plant uses the latest technology to produce both instant and agglomerated cold water swelling starches. The native ColdSwell starches are also available as organic ColdSwell. The market launch of KMC’s new ColdSwell range means that modified starches such as E1412, E1414, E1420 and E1422 are now available. All of these are guaranteed GMO free. |
