【摘要】 为分析前期开发的护色剂对辐照处理辣椒红油理化性质的影响,将护色剂番茄红素、虾青素、β-胡萝卜素和玉米黄质按前期研究的最优比例加入辣椒红油中,用⁶⁰Co-γ进行辐照处理,剂量为2、4、6、8、10 kGy。辐照后测定其酸价、过氧化值、硫代巴比妥酸值以及脂肪酸组成。结果表明,相同剂量⁶⁰Co-γ辐照后,添加护色剂的辣椒红油酸价、过氧化值和硫代巴比妥酸值有所降低;部分辐照剂量下,添加护色剂的指标略高于未添加护色剂的指标,但是差异不显著（p>0.05）,说明护色剂对辣椒红油的基本理化性质以及脂肪酸组成没有不利的影响。再将护色工艺应用于麻辣灯影牛肉的辐照护色中,辐照剂量为5、8 kGy,结果显示,相较于未添加护色剂的样品,其吸光度有显著增加（p<0.05）,初始含菌量有所增加,但辐照后会保持在较低的数量级,同时添加护色剂后麻辣灯影牛肉的感官品质、酸价、过氧化值、硫代巴比妥酸值与未添加护色剂的相比没有显著性差异（p>0.05）,适合在实际生产中推广应用。更多还原

【Abstract】 This study aimed to analyze the effects of the color retention agent that was invented before on the physicochemical properties of irradiated chili oil. Lycopene,astaxanthin,β-carotene,and zeaxanthin were added to the chili oil according to the optimal proportion of previous studies. Then~ (60) Co-γ was used for irradiation with the doses of 2,4,6,8,and 10 kGy. Acid value,peroxide value,thiobarbituric acid value,and fatty acid composition were measured after irradiation. The results showed that the acid value,peroxide value,and thiobarbituric acid value of chili oil decreased after the same dose of irradiation. Under partial irradiation dose,the indicators of chili oil with color retention agent were slightly higher than those without color retention agent,but the difference was not significant (p>0.05). The obtained results indicated that no adverse effect of the color retention agent was detected on the physicochemical properties and fatty acid composition of chili oil. The color retention agent was applied to spicy translucent beef slices for color protection with irradiation doses of 5 kGy and 8 kGy. The results showed that the absorbance of the sample increased compared with that of the sample without color retention agent (p<0.05),and the initial bacterial load increased,but remained at a low level after irradiation. At the same time,there were no significant differences in sensory quality,acid value,peroxide value,and thiobarbituric acid value between the spicy translucent beef slices with color retention agent and those without color retention agent (p>0.05),suggesting that color retention agent was suitable for application in practical production.更多还原
