由猪血液制备的亚硝基血红蛋白对红肠品质影响的研究 总被引:1,自引:0,他引:1
将由猪血制备的亚硝基血红蛋白添加于哈尔滨红肠中,研究不同添加量对产品颜色、pH 值、硫代巴比妥酸反应物值(TBARS)、菌落总数亚硝酸钠残留量以及感官质量的影响。结果表明,亚硝基血红蛋白具有增加红肠制品红度值a* 的作用,且添加量0.15% 效果最为明显。添加一定量亚硝基血红蛋白可以明显降低肉制品TBARS值,表明亚硝基血红蛋白具有一定的抗氧化作用,且添加量越大抗氧化能力越强;同时,亚硝基血红蛋白也可以降低肉制品菌落总数以及亚硝酸钠残留量;对红肠进行感官评定表明,添加0.15%亚硝基血红蛋白的红肠具有最好的感官的可接受度。本实验表明由猪血制备的亚硝基血红蛋白可以替代亚硝酸盐应用于红制品,起到发色和一定的抑菌作用,而且对产品的感官质量有一定的改进作用。 相似文献

亚硝基血红蛋白与防腐剂复合使用对红肠品质的影响 总被引:1,自引:0,他引:1
将猪血制备的亚硝基血红蛋白与防腐剂进行一定的复合并添加于哈尔滨红肠中,与添加100 mg/kg亚硝酸钠、0.15%亚硝基血红蛋白以及单独添加防腐剂的红肠为对比,研究不同添加物对产品颜色、pH值、硫代巴比妥酸反应物值(TBARS)、菌落总数、亚硝酸钠残留量以及感官质量的影响。结果表明,复合物具有增加红肠制品红度值a*的作用,可以明显降低肉制品的TBARS值,表明复合物具有抗氧化作用;同时,亚硝基血红蛋白也可以降低肉制品菌落总数以及亚硝酸钠残留量;对红肠进行感官评定表明,添加复合物的红肠具有最好的感官可接受度。结果表明由猪血制备的亚硝基血红蛋白与防腐剂复合可以替代亚硝酸盐应用于红肠制品,起到发色、抑菌和抗氧化的作用,而且可以提高产品的感官质量。 相似文献

以猪血和亚硝酸钠合成的亚硝基血红蛋白亚基色素为对象,通过光谱扫描、菌落总数测定和肉制品发色试验,研究色素在不同保存状态下的稳定性,以确定其保质期限。另外通过色差计测定该色素所制肉制品在贮藏期内的颜色变化,来判断色素发色的稳定性。结果表明:在-29℃冷冻条件下和采用真空冷冻干燥手段保存亚硝基血红蛋白亚基色素较为理想,保质期为6个月之久。而在肉制品贮藏期内,其色泽同样保持稳定,证实该色素添加到灌肠肉制品中是可行的。 相似文献

The Cheddar cheese colorant annatto is present in whey and must be removed by bleaching. Chemical bleaching negatively affects the flavor of dried whey ingredients, which has established a need for a better understanding of the primary colorant in annatto, norbixin, along with cheese color alternatives. The objective of this study was to determine norbixin partitioning in cheese and whey from full-fat and fat-free Cheddar cheese and to determine the viability of bixin, the nonpolar form of norbixin, as an alternative Cheddar cheese colorant. Full-fat and fat-free Cheddar cheeses and wheys were manufactured from colored pasteurized milk. Three norbixin (4% wt/vol) levels (7.5, 15, and 30 mL of annatto/454 kg of milk) were used for full-fat Cheddar cheese manufacture, and 1 norbixin level was evaluated in fat-free Cheddar cheese (15 mL of annatto/454 kg of milk). For bixin incorporation, pasteurized whole milk was cooled to 55°C, and then 60 mL of bixin/454 kg of milk (3.8% wt/vol bixin) was added and the milk homogenized (single stage, 8 MPa). Milk with no colorant and milk with norbixin at 15 mL/454 kg of milk were processed analogously as controls. No difference was found between the norbixin partition levels of full-fat and fat-free cheese and whey (cheese mean: 79%, whey: 11.2%). In contrast to norbixin recovery (9.3% in whey, 80% in cheese), 1.3% of added bixin to cheese milk was recovered in the homogenized, unseparated cheese whey, concurrent with higher recoveries of bixin in cheese (94.5%). These results indicate that fat content has no effect on norbixin binding or entrapment in Cheddar cheese and that bixin may be a viable alternative colorant to norbixin in the dairy industry. 相似文献

Natural colorant (no colorant, NC = 0%; moderate colorant, MC = 1.2%; high colorant, HC = 3.6% w/w) and salt (regular salt, RS = NaCl; reduced sodium, ReS = KCl; no salt, NS) were added in mayonnaise‐based dipping sauces to evaluate effects of colorant concentration and ‘natural colorant’ or ‘sodium content’ claim on saltiness expectation, consumer liking and emotion, and purchase intent (PI) of these products. Regardless of the salt type and content, increasing colorant concentration decreased colour liking scores while saltiness expectation tentatively increased as indicated by higher % of ‘too much’ responses for saltiness on a JAR (Just‐About‐Right) scale. At a given salt type and content, liking scores of salty taste decreased with increasing colorant concentration, both before and after the ‘sodium content’ claim was given to consumers. Emotion scores elicited by consuming dipping sauces were affected by colorant concentration. Positive emotions (good, interested, satisfied) decreased while negative emotions (guilty, unsafe, worried) increased with increasing colorant concentration. Statements of ‘natural colorant’ and ‘sodium content’ claim had minimal effects on elicited emotions and PI. 相似文献
