都匀市熏肉制品中亚硝酸盐含量的测定
|
摘要
亚硝酸盐,主要为亚硝酸钠,与蛋白质结合后能保持肉质的色香味,具有抗腐抑菌及让肉制品产生特殊风味。但人体吸收维生素A会受到亚硝酸盐的干扰,导致血脂降低、心跳过速等症状。都匀市市民喜爱食用腊肉等熏肉制品,因此,对都匀市内各大超市上架的熏肉制品进行亚硝酸盐检测,对都匀市市民选择食用熏肉制品有着很重要的意义。本研究采用分光光度法对都匀市富万家、宾隆、永辉三家超市上架的腊肉和腊肠中的亚硝酸盐进行了检测,结果显示都匀市上架的腊肉和腊肠亚硝酸盐含量在1. 80—9. 37mg/kg之间,均未超出国家标准30mg/kg,市民可放心选购。
Nitrite, mainly sodium nitrite, were able to maintain the color and fragrance of meat, and it has function of anti-corrosion, antimicrobialand producing special flavor in meat products. While the absorption of vitamin A by human body is affected by nitrite, which lead to reducing blood lipid and tachycardia after absorption of vitamin A. Besides, the citizen love to eat smoked meat products in Duyun. Therefore, it' s very important to determine nitrite content in smoked meat products in Duyun and then provide reference to them. Using spectrophotometry method, the nitrite contents in cured meat and sausages purchased from Binglong, Yonghui, Fuwanjia( three biggest supermarkets in Duyun), were determined and the results show that the nitrite contents range from1. 80 — 9. 37 mg/kg, while the national standards is 30 mg/kg,therefore, it' s safe to buy and eat for the citizen in Duyun.
