Fired food product which microwave-reheated affect of crust not crispness. The cause of this problem is the water molecule evaporates and moves out of food effect to water content of food.
therefor, coating helps prevent moisture loss and prevents oil being absorbed into the meat.
And operation of microwave is is molecule alignment and migration of charge ions in the rapidly alternating electromagnetic field generates heat within foods.
This study use mackerel nugget which is coated with hydrocolloid, hydroxypropylmethylecellulose (HPMC), in batter. The HPMC coating inhibits effectively the diffusion of water molecules from mackerel meat into the crust during microwave-reheated. Measurement and analysis consist of color and oil content of crust, crispness of crust in batter and bread mackerel nugget.
My senior project study of substance which affects to the quality of crispness of chicken nugget. I chose hydrocolloid for coating. This paper use mixture hydrocolloid in batter but my project use hydrocolloid in coat chicken nugget instance.
This study was made to know that the improvements batter with hydrocolloid is not the goal .
