  • The effects of adding mechanically deboned chicken (MDC) hydrolysates on the quality characteristics of imitation crab stick (ICS) during storage were investigated. ICS was prepared from Alaska Pollack, chicken breast surimi, and protein hydrolysates enzymatically extracted from MDC. ICS samples were divided into 4 groups: without protein hydrolysate (control), added with 0.5% protein hydrolysate (T1), added with 1.0% protein hydrolysate (T2), and added with 1.5% protein hydrolysate (T3). Results showed that crude protein content did not differ significantly among the ICS samples (p>0.05). ICS sample added with MDC hydrolysates had higher crude fat and ash content but lower moisture content than the control (p<0.05). Lightness was significantly lower in T2 and T3 than in the other groups at 0 and 4 wk of storage. Also, whiteness decreased in the groups contained MDC hydrolysates. Breaking force and jelly strength were higher in samples containing MDC hydrolysates compared to control samples (p<0.05). Additionally, saturated fatty acid contents were lower in the groups containing MDC hydrolysates than in control sample groups (p<0.05). Polyunsaturated fatty acid (PUFA) and essential fatty acids (EFA) were significantly higher in T2 and T3 than the control samples. In particular, all samples containing MDC hydrolysates had reduced thiobarbituric acid-reactive substances (TBARS) values at 4 wk. Free radical scavenging activity also was increased with addition of MDC hydrolysates.

  • Imitation crab stick samples were made from Alaska pollack with protein recovered from spent laying hens breast meat (C), Alaska pollack with spent laying hens breast recovered protein and cordyceps powder (T1), Alaska pollack with spent laying hens breast recovered protein and silkworm cocoon powder (T2), and Alaska pollack with spent laying hens breast recovered protein and conjugated linoleic acid (CLA) (T3). There were no significant differences in moisture, crude protein and crude fat among the imitation crab samples. pH was significantly higher in T2 and T3 compared with C and T1 after 4 weeks of storage. The values of $L^*$, $a^*$, $b^*$, and W (whiteness) in T3 were found to be more stable during storage and W in T3 was significantly higher than other samples. T3 was significantly lower in hardness, brittleness, gumminess and adhesiveness after 4 weeks of storage. Thiobarbituric acid reactive substance (TBA) values decreased with storage, whereas volatile basic nitron (VBN) values increased with storage periods in all samples. In sensory evaluation, there were no significant differences in color, odor, taste, tenderness, juiciness and overall acceptability among the samples. T3 was significantly lowest in quality among the treated samples.

  • As customers pay more attention to choosing food that will support their health, many people in the academic and industrial world have focused on developing foods made with bioactive components. Thus, the use of bioactive components rather than synthetic materials has increased. Because there are no limits to how bioactive components can be used, customers assume they are highly reliable and healthy to consume. In the present study, imitation crab stick samples were made from Alaska Pollack with breast recovered protein from spent laying hens and silkworm cocoon powder (10 g) (T1), Alaska Pollack with breast recovered protein from spent laying hens and silkworm cocoon powder (5 g) + cordyceps powder (5 g) (T2), and Alaska Pollack with breast recovered protein from spent laying hens and cordyceps powder (5 g) + conjugated linoleic acid (CLA) (5 g) (T3). The pH and shear force increased after 2 weeks of storage in all three samples. Shear force was significantly higher in the T3 sample in comparison to the T1 and T2 samples. In meat color, redness ($a^{\ast}$) and whiteness (W) increased as the storage periods increased in all three samples, whereas yellowness ($b^{\ast}$) decreased during storage. The T2 sample was significantly higher in redness ($a^{\ast}$), yellowness ($b^{\ast}$), and deformation than the other two samples. The addition of bioactive components did not influence the texture properties in any of the samples. Lipid oxidation (thiobarbituric acid reactive substances [TBARS]) and microorganism count (total plate count [TPC]) were significantly higher in the T1 sample than the two other samples, whereas protein degradation (volatile basic nitrogen [VBN]) was higher in the T2 sample than the other samples. Total amino acid content decreased in the T1 and T3 samples as the storage period increased. Consequently, the T3 sample of Alaska Pollack with breast recovered protein from spent laying hens and cordyceps powder (5 g) + conjugated linoleic acid (CLA) was found to have the necessary functionality to be considered for use in making imitation crab sticks.
