  • Cacao bean husk (Theobroma cacao L.) contains a high level of dietary fiber and therefore can be used as raw material in food processing. The objective of the present study was to measure the physicochemical properties and sensory traits of emulsion-type pork sausages with various levels of cacao bean husk powder (0.25%, 0.5%, 0.75%, 1%, and 2%). The moisture content in cooked sausages increased as the level of cacao bean husk power increased, whereas the protein content decreased (p<0.05). With respect to color, as the level of cacao bean husk power increased, there was a decrease in lightness and yellowness, but there was a considerable increase in redness (p<0.05). Cacao bean husk powder exhibited a positive effect on emulsion stability and apparent viscosity. In the sensory evaluation, increased level of cacao bean husk increased flavor acceptability; the 0.75% and 1% treatment groups showed significantly high overall acceptability (p<0.05). The thiobarbituric acid reactive species content of cooked sausages indicated that with the addition of cacao bean husk powder significantly inhibited lipid oxidation in the sausages during refrigerated storage (p<0.05). Overall, the findings of the present study suggest that adding 0.75% and 1% cacao bean husk powder as a natural ingredient in sausages can help develop meat products with excellent qualities.

  • Although the mackerel is an excellent food, there are disadvantages of its own smell and its shelf-life. So this study aimed to examine the quality assessment, shelf-life and acceptability of mackerel marinated with different amounts of thyme extract through the salinity, pH, texture, change of color, and sensory evaluation for reducing the smell of it and improving the shelf-life and acceptability of it with the thyme of various physiologic activities. The salinity of mackerel marinated with different amounts of thyme was a lower 2% than that of the existing salted mackerel, 5%, when producing the salted mackerel in the experimental method of this study, reducing the intake of salt. The shelf life of the existing salted mackerel was up to 4 weeks, while that of the salted mackerel marinated with thyme extract was up to 5 weeks. The change in pH during storage showed that the salted mackerel marinated with thyme extract after 5 weeks were within the initial decomposition of dark-fleshed fishes, pH 6.2-6.4, which the shelf life was extended due to the preservative effect of antioxidant content. The acceptability test showed that T 1 marinated with 1% thyme extract was ideal in all flavor, taste and general acceptability.
