Abstract
|
|
|
|
Low-fat pork sausages (LFPS) were prepared with 1% transglutaminase (TG) and 0.5% sodium caseinate (SC), and with or without different type of hydrocolloids (0.3%; acorn, AC or mungbean, MB) to evaluate the effects of these ingredients on the physicochemical and textural properties of LFPS with reduced salt. pH, moisture content (%) and lightness of low-fat/salt pork sausages (LFSPS) were affected by the addition of TG combined with SC (TG-SC) and acorn or mungbean powders affected the lightness and yellowness of LFSPS. However, cooking yield of LFSPS decreased, while textural properties were increased with the addition of TG-SC combination, which did not affect expressible moisture contents (%) of LFSPS. Both AC and MB tended to improve the cooking yield and water holding capacity of LFSPS, especially, MB rather than AC. However, these had no effect on the textural properties of LFSPS, except for textural chewiness. These results indicated that AC and MB powders could be used as a water binding agent in TG-SC combination of LFSPS.
