Effects of addition of Kappaphycus alvarezii on physicochemical properties and lipid oxidation of mechanically deboned chicken meat (MDCM) sausages

Abstract

Purpose

The purpose of this paper is to determine both the physicochemical properties and lipid oxidation of sausages made from mechanically deboned chicken meat (MDCM) and the edible seaweed, Kappaphycus alvarezii (KA).

Design/methodology/approach

Four different sausage formulations were produced with different formulations containing 0(KA0), 2 (KA2), 4 (KA4) and 6 per cent (KA6) of KA.

Findings

Results have shown that the addition of KA increased the hardness and chewiness parameters, water holding capacity, redness (a*-value) and the pH value of the MDCM sausages (p<0.05). The adhesiveness, cohesiveness and springiness of all formulations showed no significant differences (p>0.05). The addition of KA reduced the cooking loss of MDCM sausages (p<0.05). However, the addition of KA made the sausages darker (lower L*-value) (p<0.05). Furthermore, the addition of KA aided in the reduction of lipid oxidation in the MDCM sausages when they were refrigerated at a temperature of 4°C for 12 days. The MDCM sausages that contained KA had lower two-thiobarbituric acid test values compared to the control sample (p<0.05) during the 12 days of storage at 4°C.

Originality/value

The addition of KA seaweed can potentially produce better quality MDCM sausages in terms of physicochemical properties and reduce the rate of lipid oxidation.
