Acrylamide is a contaminant as defined in Council Regulation (EEC) No 315/93 and as such, it is considered a chemical hazard in the food chain. The toxicity of acrylamide has been acknowledged since 2002, among its toxicological effects on humans being neurotoxicity, genotoxicity, carcinogenicity, and reproductive toxicity. Acrylamide has been classified as carcinogenic in the 2A group, with human exposure leading to progressive degeneration of the peripheral and central nervous systems characterized by cognitive and motor abnormalities. Bakery products (bread, crispbread, cakes, batter, breakfast cereals, biscuits, pies, etc.) are some of the major sources of dietary acrylamide. The review focuses on the levels of acrylamide in foods products, in particular bakery ones, and the risk that resulting dietary intake of acrylamide has on human health. The evolving legislative situation regarding the acrylamide content from foodstuffs, especially bakery ones, in the European Union is discussed underlining different measures that food producers must take in order to comply with the current regulations regarding the acrylamide levels in their products. Different approaches to reduce the acrylamide level in bakery products such as the use of asparginase, calcium salts, antioxidants, acids and their salts, etc., are described in detail.
The aim of this study was to investigate the possibility of reducing the acrylamide content of bread samples obtained from wheat flour with a high extraction rate by adding a dry sourdough (SD) into the bread recipe. According to the data obtained, compared to the control sample the acrylamide content was significantly reduced (p < 0.05) by more than 50% for the bread samples in which low levels of SD of 1–3% were added to wheat flour. More so, due to the fact that SD affects bread quality, its technological effects on bread making have been investigated. The dough’s rheological properties (mixing and pasting using Mixolab, extension using Alveograph, fermentation using Rheofermentometer), falling number value, and bread quality parameters (loaf volume, porosity, elasticity, color, textural and sensory qualities) have been investigated. In general, SD addition caused a weakening effect on wheat flour dough, an increase in the total volume of CO2 produced during fermentation and a decrease in the falling number value. On bread quality, SD addition improved bread physical characteristics, darkened the bread crumb and crust, decreased the textural parameters (firmness, gumminess, cohesiveness and resilience) and improved the bread sensory characteristics for the samples with the addition of 1–2% SDto wheat flour.
Cereal products are the most consumed in Romania being the main contributors to daily acrylamide exposure. The paper aims to present for the first time a general situation regarding the evolution of the acrylamide levels content from cereal products, on the Romanian market, during 2017-2018 periods, as a result of legislative measures imposed by the European Union (EU). For this purpose, the levels of acrylamide in 55 selected cereal products samples were evaluated. The cereal products analyzed were grouped in biscuits, confectionery, expanded cereals, bakery products and specialties. The acrylamide content from the cereal products were detected using GC-MS/MS method. The highest level of acrylamide was found in biscuits, whereas the lowest level was determined in bakery products. The most of the cereal products samples analyzed (90.9%) was below the reference levels established by the EU Regulation for the acrylamide level from 2017 EC (2013/647/EU) and 2018 EC (2017/2158/ EU). From the 55 cereal products analyzed, only 5 biscuits samples exceeded the reference levels established by the European Commission, one in 2017 and four in 2018 period.
