Abstract:

The study aimed to obtain a low-sweetness, low-calorie and economic composite cryoprotectant which mitigates
the negative effect of frozen storage on the eating quality of chicken meatballs. Trehalose and polydextrose were selected for
combination with two traditional commercial cryoprotectants (sucrose and sorbitol) to design a three-level orthogonal array.
Thawing loss, expressible moisture and texture properties were determined. The results showed that the optimal combination
was trehalose 1.0%, polydextrose 4.0%, 3.0% sucrose and sorbitol 2.0%. The addition of the composite cryoprotectant in frozen
chicken meatballs could effectively improve the water holding capacity and texture properties of frozen chicken meatballs.

Key words: trehalose, polydextrose, chicken meatballs, eating quality
