Acrylamide in fried and baked foods has the potential to cause toxic effects in animals and humans. A major challenge lies in developing an effective strategy for acrylamide mitigation in foods without altering its basic properties. Food scientists around the world have developed various methods to mitigate the presence of acrylamide in fried food products. Mitigation techniques using additives such as salts, amino acids, cations and organic acids along with blanching of foods have reduced the concentration of acrylamide. The use of secondary metabolites such as polyphenols also reduces acrylamide concentration in fried food products. Other mitigation techniques such as asparaginase pre‐treatment and low‐temperature air frying with chitosan have been effective in mitigating the concentration of acrylamide. The combined pre‐treatment process along with the use of additives is the latest trend in acrylamide mitigation. © 2018 Society of Chemical Industry 相似文献

目的:研究不同米炒党参在炮制过程中党参炔苷、5-HMF和党参多糖的动态变化。方法:高效液相色谱法测定党参炔苷、5-HMF含量,紫外-可见分光光度法测定党参多糖含量动态变化过程。结果:(1)党参炔苷:随着炒制时间的延长,党参炔苷含量均呈先上升后下降趋势;在相同时间间隔点,小米炒党参炔苷含量较高。(2)5-HMF:随着炒制时间的延长,5-HMF含量均呈显著上升趋势;在相同时间间隔点,小米炒党参5-HMF含量较低。(3)党参多糖:随着炒制时间的延长,党参多糖含量均呈先上升后下降趋势;在相同的时间间隔点,炒制时间为5.5min之前的样品中小米炒党参多糖含量均高于大米炒党参,炒制时间为5.5min之后的样品中小米炒党参多糖含量均略低于大米炒党参。结论:党参分别采用小米、大米炒制后,3种成分均发生了显著变化,但小米炒党参和大米炒党参变化趋势不一致。 相似文献

Composition and functionality of wheat bran and its application in some cereal food products 总被引:3,自引:0,他引:3 下载免费PDF全文

Production of wheat bran (WB) for human consumption is estimated to be about 90 million tonnes per year. WB is a cheap and abundant source of dietary fibre which has been linked to improved bowel health and possible prevention of some diseases such as colon cancer. It also contains minerals, vitamins and bioactive compounds such as phenolic acids, arabinoxylans, alkylresorcinol and phytosterols. These compounds have been suggested as an aid in prevention of noncommunicable diseases such as cardiovascular disease. This article discusses WB extraction, its nutritional properties, potential health benefits, effects on quality and sensory properties of some cereal foods, and its application in some baked products as well as in fried cereal snacks, as an additive for oil reduction and fibre enrichment. 相似文献

GC-MS测定薯类油炸食品及洋快餐中丙烯酰胺 总被引:1,自引:0,他引:1
利用中国疾病预防控制中心营养与食品安全所的样品前处理方法,采用气相色谱和四级杆一级质谱联用技术对薯类油炸食品及洋快餐两类8种食品中丙烯酰胺进行了测定,以相对保留时间和丙烯酰胺相应监测离子的丰度进行定性分析。结果表明,丙烯酰胺标准各浓度水平的相对响应因子RRF的相对标准偏差(RSD)小于20%,满足内标法计算要求,薯类油炸食品丙烯酰胺含量为456~5269μg/kg,洋快餐食品中丙烯酰胺含量为147~214μg/kg。 相似文献

“Sev,” savory prepared from chickpea flour is a popular snack item for its appealing flavor and texture. Mapping and positioning of market samples consisting different varieties like Small (S1, S2, S3), Medium (M1, M2, M3), and Big (B1, B2, B3, B4) were carried out using principal component analysis. Samples were subjected to sensory profiling resulting in small variety samples were crisper compared to other varieties. Texture measurement indicated breaking strength was higher in big variety samples. Color analysis showed significant difference in L*, a*, and b* values. Principal component analysis results indicated that S1 and S2 were associated with crispness, uniform texture, and typical fried oil aroma. Commercially available sev samples were significantly different in their quality parameters, which was indicated by the study. Study showed that small variety (S3) had the highest overall quality among all the samples, which also had high sensory scores for crispness. 相似文献
