Effects of Time, Temperature and ShearIn selecting the proper starch to do the job, one must also consider the processing temperature,the length of time at that temperature and the forces of shear that the pasted starch willencounter.The higher the temperature, the greater the shear and longer the time exposed to these forces, themore swollen the granule and the more fragile and susceptible it is to rupture. We can build intolerances to shear, temperature and acid by supplementing hydrogen bonds in the granule bycross-linking. (Figs. 14 & 15).
