Abstract
Root and root-type starch derivatives having controlled acetyl substitution levels which provide an initial high paste viscosity to facilitate uniform filling operations when used as a food canning medium, and which break down to a thinner viscosity upon heating to facilitate heat penetration into the canned food mass for sterilization of the canned food product and to provide a more acceptable watery or soup-like consistency to the food product. Blends of several root and root-type starch derivatives make possible a predictable final viscosity level which is not completely 'water-thin.' The selection of acetylating agent also affects the final viscosity level of the starch canning medium. It has been observed that a starch derivative substitute using vinyl acetate provides a slightly higher final viscosity under the same retorting conditions when compared to a starch derivative which has been substituted using acetic anhydride.
