Hence, constituent fatty acids in NL of maize (<jats:italic>Zea mays<\/jats:italic>) and rye flour (<jats:italic>Secale cereale<\/jats:italic>), and in sourdough and final <jats:italic>broa<\/jats:italic> manufactured from a mixture therefrom were quantitated. Methodologies of esterification of fatty acids, as well as of transesterification of acyl lipids and sterol esters (SE) were improved. The <jats:italic>n<\/jats:italic>\u2010hydrocarbons containing between 4 and 24 carbon atoms were then resolved and identified by gas\u2013liquid chromatography. Regarding total neutral lipids (TNL) in all samples, 79\u201389% were TAGs, and 87\u201393% were TAGs and DAGs in the case of free lipids (FL). Furthermore, 73\u201385% of TNL in bound lipids (BL) and 65\u201380% of TNL in starch lipids (SL) were TAG and free fatty acids (FFA). Conversely, only 4\u20135%, 6\u201316%, and 7\u201310% of TNL in FL, BL, and SL, respectively, were SE and MAGs. TAGs and DAGs underwent partial hydrolysis during fermentation and baking; palmitic, oleic, and linoleic acids were dominant as products released. The nutritional value of <jats:italic>broa<\/jats:italic> lipids was apparent owing to their proportions of SE (4%) and DAG (9%), coupled with 52% of linoleic acid in all samples\u2014as well as to the high contents of polyunsaturated versus monounsaturated or saturated fatty acids, and to the general dominance of UFA.<\/jats:p>","DOI":"10.1002\/ejlt.201100208","type":"journal-article","created":{"date-parts":[[2011,11,8]],"date-time":"2011-11-08T11:57:19Z","timestamp":1320753439000},"page":"294-305","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Composition of neutral lipid classes and content of fatty acids throughout sourdough breadmaking"],"prefix":"10.1002","volume":"114","author":[{"given":"Jo\u00e3o M.","family":"Rocha","sequence":"first","affiliation":[]},{"given":"Paavo J.","family":"Kalo","sequence":"additional","affiliation":[]},{"given":"F.
