Abstract

Potency of culled Saanen crossbred goat meat to replace the supply of yearling Boer crossbred goat meat was evaluated. Selected muscles from leg and shoulder cuts were analysed for their nutritional (proximate composition, collagen, amino acids, fatty acids), physicochemical (pH, myoglobin, drip loss, cook loss, shear force, lightness (L*) redness (a*) yellowness (b*), microstructure), and sensory (triangle test, hedonic test) evaluations. Meat samples from culled Saanen crossbred goat exhibited higher values in protein, collagen, and MUFA (P<0.05) than those from Boer crossbred goat, while lower values in ash, soluble collagen, and SFA were obtained (P<0.05). Meat from culled Saanen crossbred goat revealed higher cook loss, shear force, and redness compared to those from a yearling Boer crossbred goat (P<0.05). In addition, thicker perimysium in meat of Saanen crossbred goat was obtained particularly that could be seen on leg part. In sensory evaluation result, the panels could detect the differences between raw meat characteristics of these goat breeds (P<0.05) within the same muscle. However, the panels could not distinguish the difference between breeds in leg meat after being cooked. Shoulder meat of Saanen crossbred goat had less acceptance level compared to the other samples (P<0.05) particularly on its texture and taste quality. In summary, shoulder cut of culled Saanen crossbred goat exhibited a well-intentioned potency to substitute the supply of meat from yearling Boer crossbred goat. Nevertheless, pre-treatment might be applied to leg cut of Saanen crossbred goat to solve the less acceptance level of its textural and taste characteristics.

Abstract

The effects of ginger and pineapple juices on pH, color (L*, a*, b*), thiobarbituric acid reactive substances (TBARS), sensory intensity, and sensory preference of culled goat meat were determined.Completely randomized design (CRD) and randomized completely block design (RCBD) were applied for physicochemical attributes and sensory profiles, respectively. In raw condition, the pH of ginger-marinated sample was higher than that of pineapple-marinated sample. The increased trend in pH was found in the ginger-marinated and control-marinated samples, while the decreased trend was found in pineapple-marinated sample. A better redness stability of ginger-marinated sample was observed during the storage. Both plant juices had significant effects on controlling the malonaldehyde (MDA) formation. Ginger-marinated sample exhibited a brighter red color, less gamey odor, stronger marinated odor, and higher preference. In cooked samples, increasing pH but still with similar trend as in all raw samples was recorded. L* and b* of all samples were decreased on the fifth day of storage, while a* of ginger-treated sample was immensely elevated. Marinated juices were significant on retarding MDA formation along with less browning color and gamey aroma intensities. Reddish-brown color and stronger marinated odor resulted in high preferences on ginger-marinated sample. Less brown color in pineapple-marinated sample contributes to lower color and overall acceptances. In conclusion, ginger juice had a significant effect on covering the gamey flavor and showed positive effect on other sensory-supported attributes.
