The purpose of this paper is to determine the physicochemical and sensory properties of fish patties added with banana peel powder (BPP), Musa balbisiana.

Four different fish patty formulations were produced containing 0 per cent (BPP0) (Control), 2 per cent (BPP2), 4 per cent (BPP4) and 6 per cent (BPP6) of BPP (M. balbisiana).

The addition of BPP was shown to improve the hardness, cooking yield, water holding capacity (WHC) and redness (a* value) as well as the dietary fibre (DF) content (p<0.05). The BPP, however, also turned the fish patties darker (lower L*) (p<0.05). Sensory evaluation showed that fish patties with a concentration of 2 per cent BPP had the highest overall acceptability, whereas the concentration of 6 per cent BPP was found to be unacceptable compared to that of control sample (p<0.05). The declining sensory acceptability of fish patty with 6 per cent BPP is related to the harder texture and the darker color of the patties compared to the control sample (BPP0).

The addition of BPP can potentially improve the quality of fish patties in terms of textural properties (hardness) by increasing their WHC, reducing the cooking loss and enhancing the DF content.

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).

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

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.

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