Özet

The effects of direct addition of low and medium molecular weight chitosan at different levels (0.25, 0.50, 0.75 and 1%) to beef chops on the formation of heterocyclic aromatic amines (HCAs) were investigated. Chops were cooked at three different temperatures (150, 200 and 250 degrees C). The use of chitosan had very significant effects on water content, pH and cooking loss values of the samples. Cooking temperature had very significant effects on water content and cooking loss, while it had significant effect on pH value. On the other hand, molecular weight of chitosan had very significant effects on water content and cooking loss. While IQ and MeA alpha C were not detected, varying amounts of IQx (up to 0.45 ng/g), MelQx (up to 0.09 ng/g), MeIQ (up to 0.07 ng/g), 7,8-DiMeIQx (up to 0.15 ng/g), 4,8-DiMeIQx (up to 0.05 ng/g), PhIP (up to 2.94 ng/g) and A alpha C (up to 0.68 ng/g) were detected. While the total HCA content ranged between nondetectable level and 4.21 ng/g, chitosan addition decreased (14.3-100%) the total HCA content. (C) 2015 Elsevier Ltd. All rights reserved.
