METHOD OF MEASURING PH OF FOOD DOUGH AND AUTOMATICALLY CONTROLLING PH OF THE DOUGH

摘要

PURPOSE:To directly measure the pH of food dough in a short period of time with a simple operation and good accuracy by inserting a pH sensor into the food dough having 30-200% water absorptivity or bringing the sensor into direct contact therewith. CONSTITUTION:The pH of the food dough 1 having 30-200% water absorptivity is directly measured by inserting the pH sensor 2 into the food dough or bringing the same into direct contact therewith in this method. The food to be subjected to the pH measurement may be the food having >=30% and <=200% water absorptivity and is usually the food dough produced by using 1 kinds or more kinds of powders of grains or beans or the starches extracted and prepd. therefrom as essential raw materials, and adding various side raw materials thereto, then mixing the raw materials. The pH sensor to be used may be the sensor having the shape to allow the smooth contact of the sensor with the dough and the sensors of preferably a needle type and flat type are used.
