The ferrozine, the Schricker and modified Schricker methods were used to measure the non-heme iron in raw and cooked turkey meat. The ferrozine method gave the lowest non-heme iron values, while results from the Schricker and modified Schricker were not different (p<0.05). When hemoglobin (Hb) was added to breast meat, how-ever, differences (p<0.05) between the Schricker and modified Schricker, and Schricker and ferrozine methods were observed in cooked meat with NaCl. Cooking and addition of NaCl caused increase in measured nonheme iron content and had a synergistic effect on the release of nonheme iron in meat. 相似文献

The effects of antioxidants or hot packaging and their combination on lipid oxidation were quite variable depending on the additives in turkey meat. The TBARS values of cooked patties were greatly affected by the degree of oxidation in the raw meat, and the effectiveness of antioxidants varied with added prooxidants. Ascorbate and free radical terminators had stronger antioxidant effects than iron chelators, and chelating iron alone could not eliminate lipid oxidation in either raw or cooked meat with added NaCl. The combination of hot packaging and antioxidants provided cooked patties with better protection from lipid oxidation than either treatment alone. 相似文献

The problem of packing circles into a domain of prescribed topology is considered. The circles need not have equal radii. The Collins-Stephenson algorithm computes such a circle packing. This algorithm is parallelized in two different ways and its performance is reported for a triangular, planar domain test case. The implementation uses the highly parallel graphics processing unit (GPU) on commodity hardware. The speedups so achieved are discussed based on a number of experiments. 相似文献

Proof of retrievability (POR) is a technique for ensuring the integrity of data in outsourced storage services.In this paper,we address the construction of POR protocol on the standard model of interactive proof systems.We propose the first interactive POR scheme to prevent the fraudulence of prover and the leakage of verified data.We also give full proofs of soundness and zero-knowledge properties by constructing a polynomial-time rewindable knowledge extractor under the computational Diffie-Hellman assump... 相似文献

Polyphenol oxidase (Isozyme I) from potato was extracted and purified with ammonium sulfate, cation-exchange (Bio-Rad Bio-Scale S2) and Sephadex G-100 column chromatography. The enzyme was purified 11.8 fold resulting in a specific activity of 250.3 units/mg. Optimum pH of the enzyme was 6.6. Optimum temperature of the enzyme was 40C and its half-life was 0.8 min at 70C. The Km for catechol, pyrogallol, 4-methyl catechol, caffeic acid and L-DOPA were 4.11 mM, 0.61 mM, 0.78 mM, 0.50 mM and 32 mM, respectively. However, monophenols such as tyrosine, p-cresol and 1-naphtol did not show any activity. Data for Vmax /Km which represents catalytic efficiency show that 4-methyl catechol has the highest value. The molecular weight of the active enzyme was 86,000 Da, composed of two identical subunits. The number of Cu2+ ions bound was found to be 2 per enzyme molecule. 相似文献
