阐述了食品中丙烯酰胺产生的机理.丙烯酰胺是一种具有神经毒性的小分子化合物,它主要由游离的天门冬酰胺在食品加工过程中通过美拉德反应形成.天门冬酰胺和碳水化合物是形成丙烯酰胺必需的物质基础,高温(高于120 ℃)则是丙烯酰胺形成的关键条件,加工方式、水活度、pH值等因素也影响其形成.目前食品中丙烯酰胺的分析主要采用气相色谱-质谱法(GC-MS)与液相色谱-串联质谱联用技术(LC-MS/MS).作者对丙烯酰胺的分析方法进行了研讨并对丙烯酰胺的毒理学和食用含有丙烯酰胺食品的风险进行了讨论. 相似文献

Lipid oxidation is one of the major chemical reactions occurring during food processing or storage and may have a strong impact on the final quality of foods. A significant role of carbonyl compounds derived from lipid oxidation in acrylamide formation has been recently proposed. In this work, the effect of lipid oxidation level on acrylamide formation was investigated by thermal treatment of differently formulated fat-rich model systems. Results showed that lipid oxidation positively influenced the formation of acrylamide. The effect was more evident in sugar-free system where lipid become the main sources of carbonyls. Catechins reduced acrylamide formation presumably by trapping carbohydrates and/or preventing lipid oxidation. More acrylamide was formed in model systems composed with sunflower oil than in those containing palm oil which is less susceptible to oxidation.In systems containing higher amount of water, acrylamide formation was delayed due to evaporative cooling. In these systems, the effect of catechin was more pronounced and the effect of lipid oxidation became detectable only after a prolonged reaction time.These findings suggested that lipid oxidation could become a relevant factor for acrylamide formation, particularly for dry foods with low carbohydrate content. 相似文献

Formation and reduction of acrylamide in Maillard reaction: a review based on the current state of knowledge 总被引:4,自引:0,他引:4
The recent report of elevated acrylamide levels in heat processing foods evoked an international health alarm. Acrylamide, an acknowledged potential genetic and reproductive toxin with mutagenic and carcinogenic properties in experimental mammalians, has been found in various heat processing foods. Many original contributions reported their findings on the formation mechanism and possible reduction methods of acrylamide. The aim of this review article is to summarize the state-of-the-art about the formation and reduction of acrylamide in the Maillard reaction. This research progress includes mechanistic studies on the correlation between the Maillard reaction and acrylamide, the formation mechanism of acrylamide, the main pathways of formation and impact factors on formation including cultivars, storage temperature, storage time, heat temperature, heat time, environmental pH, concentration of precursors, effects of food matrixes, type of oil, etc. Meanwhile, primary mechanisms on the reduction of acrylamide as well as reduction pathways including material and processing related ways and use of exogenous chemical additives are systematically reviewed. The mitigation studies on acrylamide are also summarized by the Confederation of the Food and Drink Industries of the EU (CIAA) "Toolbox" approach. 相似文献

食物油炸过程中,来自食物和煎炸油的各种成分会发生强烈的化学反应,产生各种各样的化学产物,最终对油炸食物的食用品质和煎炸油的使用期限产生影响。在这些产物中也存在种类较多且含量不可忽视的有害成分,其中与食品成分相关的主要有丙烯酰胺和杂环胺等伴生危害物。这些有害成分的产生可以通过选择适宜的油炸条件,如煎炸油种类、油炸时间、油炸温度和添加外源抗氧化剂等措施来加以控制。本文综述了近年来研究发现的食物油炸过程中丙烯酰胺和杂环胺的形成途径、危害及控制方法,旨在为寻找抑制食物油炸过程中伴生危害物产生的新方法提供新的思路。 相似文献

This paper summarizes the current state of knowledge on acrylamide formation in foods during thermal processing. The main
pathway of acrylamide formation in foods is linked to the Maillard reaction, and in particular, the amino acid asparagine.
Effects of several factors related to food composition and processing conditions on the formation levels of acrylamide, and
also, other quality characteristics in thermally processed foods are discussed in detail. From a process control point of
view, it is also addressed that there is a need to develop viable models for the estimation of acrylamide contents in heated
foods during the stages of process design and optimization. Fried potato products, as one of the most encountered category
of thermally processed foods, are specifically emphasized for acrylamide formation, potential ways of mitigation, and modeling
its formation during frying. 相似文献

Unconventional formulation and baking conditions were exploited for obtaining omega-3 polyunsaturated fatty acids enriched biscuits. A monoglyceride-flaxseed oil–water gel was used to obtain biscuits which had physical and chemical properties analogous to those of a control sample prepared with palm oil. To reduce fat oxidation and acrylamide and furan formation, the dough was baked at different temperature, time and pressure (i.e. varying from 101.33 to 0.15 kPa) conditions according to a central composite design. Baking at high temperature and reduced pressure allowed to obtain biscuits with acceptable water content and colour, while minimizing omega-3 fatty acids oxidation and acrylamide and furan formation. The biscuits best responding to these characteristics were obtained by applying the combination 174 °C-3.99 kPa-45 min. The low pressure generated inside the oven likely exerted a stripping effect towards acrylamide and furan as well as oxygen thus preventing toxicants to accumulate and lipid oxidation to occur. This study highlighted that the use of monoglyceride-flaxseed oil–water gel combined with baking under reduced pressure is potentially applicable at the industrial level to obtain nutritionally enhanced biscuits, while simultaneously preventing the occurrence of degradation reactions and toxic molecules formation. Due to the worldwide diffusion of cereal-based foods, including sweet biscuits, this formulation and process strategy could have a great economic impact. 相似文献

The influence of the matrix composition and structure on the capacity of asparaginase to reduce acrylamide formation in biscuits was studied. In particular, formulations differing for water (10 to 20% on total weight) and fat (0 to 15% on total weight) content, fat type (margarine, palm oil) and lipid phase distribution were considered. In the latter case, palm oil was substituted with a monoglyceride–palm oil–water gel (hydrogel). The results showed that high water contents, by favoring precursor mobility, promoted acrylamide formation as well as the enzyme capability of reducing the toxic molecule levels in the final product. On the contrary, the presence of fat significantly reduced acrylamide development and enzyme activity as compared with the fat free formulation. It can be hypothesized that the presence of fat would hamper the interaction between the precursors in the aqueous phase, leading to lower amounts of acrylamide. By substituting fat with hydrogel, the biscuit behaved as a fat free system, where acrylamide formation as well as its reduction by means of asparaginase activity was higher than in the fat-containing biscuits. It is likely that the inclusion of palm oil in the dough through the hydrogel modified the system morphology, thus not hampering the encounter among reactants and consequently favoring acrylamide formation. 相似文献

Excessive oil uptake and formation of carcinogens, such as acrylamide (AA), heterocyclic amines (HCAs), and polycyclic aromatic hydrocarbons (PAHs), during deep-frying are a potential threat for food quality and safety. Cellulose- and chitosan-based edible coatings have been widely applied to deep-fried foods for reduction of oil uptake because of their barrier property to limit oil ingress, and their apparent inhibition of AA formation. Cellulose- and chitosan-based edible coatings have low negative impacts on sensory attributes of fried foods and are low cost, nontoxic, and nonallergenic. They also show great potential for reducing HCAs and PAHs in fried foods. The incorporation of nanoparticles improves mechanical and barrier properties of cellulose and chitosan coatings, which may also contribute to reducing carcinogens derived from deep-frying. Considering the potential for positive health outcomes, cellulose- and chitosan-based edible coatings could be a valuable method for the food industry to improve the quality and safety of deep-fried foods. 相似文献
