Research on the effect of boiling and steaming to the crispness and colour of sweet potato chips will be implemented. Boiling and steaming aims to create conditions, so the slices of sweet potato gelatinization expands and becomes more crispy when fried. Some parameters which involved in steaming process need to be optimized, so the chips with the best crispness and colour are gained.
