Defining quality of
1. Dry weight. A measure of the percentage of dry weight of potato head. Measured by the specific gravity of potato head. Used as indicators of quality potato head
-International processing plant needs the proper processing potato head plates must be dry weight 22-24 percent, or more than specific gravity values 1.085
.-Processing plant in the country, Thai Determine the quality of potato head with a dry weight of not less than 17.5 percent, or has a specific gravity ranging from 1.070 or above
.Because of the dry weight and specific gravity of potato head, have a relationship with is nottas (starch) in the dry weight or specific gravity is high, there is a large quantity of flour. It will increase the value of potato head, with higher prices. Therefore, farmers grow potato plants. Want to plant potatoes, according to factory
.2. The quantity of sugar in potato head. Is important to define quality in processing potato chips, sheets (potato chip) during seed germination of potato starch will change as the sugar and sugar diosing (reducing sugar) include: glucose (glucose). (glucose)
If the potato head with high quantities of sugar the dio. When FRY oil (frying) or processed at high temperature to make the principal melody (maillard reaction), Admiral, manner in which the occurrence of Brown (browning reaction) between a pipeline with the protein. In the potato used as raw material for processing should not exceed 0.2 percent
radiation (food irradiation) 0.08-0.15 k gray. Maintained by cooler temperatures (cold storage) 10-15 degrees Celsius. Can inhibit seed germination, which causes an increase of the sugar the dio. .
In General, the factory has not been given the quantity of sugar in the potato head is the purchase receipts in the pointers, because a measurement of the amount of sugar in the potatoes quite. Cumbersome and used for long periods of time. In addition, the quantity of sugar in potato head is changed according to the conditions of storage
