Effect of plant extracts on physicochemical properties of chicken breast meat cooked using conventional electric oven or microwave.
This study evaluated effects of vacuum-infused fresh chicken breast meats with grape seed extracts, green tea extracts, or tertiary butyl hydroquinone on pH, texture, color, and thiobarbituric reactive substances after cooking using a microwave or conventional electric oven for 12 d storage at 5 degrees C. Thiobarbituric reactive substances values of uncooked (raw) chicken breast meats for 0 to 12 d of storage ranged from 1.12 to 3.5 mg of malonaldehyde/100 g of chicken. During 0 to 12 d of storage, thiobarbituric reactive substances values ranged from 2.50 to 7.80 and from 2.4 to 7.35 mg of malonaldehyde/100 g of chicken breast meat cooked by microwave and conventional electric oven, respectively. Meats cooked by microwave had higher redness and lower lightness values than those cooked by conventional electric oven. Also, meats cooked by microwave had higher maximum shear force, working of shear, hardness, springiness, cohesiveness, and chewiness values than meats cooked by conventional electric oven. Tertiary butyl hydroquinone was the most effective in raw and cooked meats in reducing lipid oxidation, followed by grape seed and green tea extracts. Plant extracts are effective in preventing undesirable changes in chemical properties in chicken breast meat caused by microwave and conventional electric oven cooking.
