The causes of the increase in drying rate of the blanched samples are considered to be 1 increasing penetration of water into the sample surface by inhibiting the hardening of the sample surface (Orikasa et al 2008) 2 destroying CMS (Watanabe et al 2017) and 3 changing the resistance to internal moisture diffusion by altering the

To find the drying rate the food is weighed placed in the dryer and left for 5 -10 minutes It is removed and re-weighed then put back in the dryer This is continued until the weig ht does not change The rate of drying can then be calculated Typical drying rates are 0 25kg per hour for solar dryers and 10-15kg per hour for artificial dryers
