Description
  • V pokusu byl sledován vliv rozdílného obsahu n-6 a n-3 PUFA v prsní a stehenní svalovině kuřat na organoleptické vlastnosti masa. Kuřata byla krmena směsmi obsahujícími 1, 3, 5 nebo 7 procent oleje připraveného buď ze lnu odrůdy Atalante (A) s vysokým obsahem kyseliny alfa-linolenové nebo z odrůdy Lola (L) s převažujícím obsahem kyseliny linolové. Maso kuřat krmených L mělo lepší senzorické vlastnosti než maso kuřat krmených A. Když svalovina obsahovala více než 180 mg n-3 PUFA/100 g, tj. stehenní svalovina při zkrmování 3 % a více A a prsní svalovina při zkrmování 7 % A, byl při senzorických zkouškách některými posuzovateli zaznamenán slabý rybí pach, rybí příchuť a mírná olejovitá pachuť. Ve vláknitosti, jemnosti a šťavnatosti prsní svaloviny nebyly průkazné rozdíly. Stehenní svalovina kuřat krmených L byla tužší, šťavnatější a chutnější než kuřat krmených A. Možnost zvyšování obsahu n-3 PUFA bez rizika zhoršení organoleptických vlastností masa jsou tedy omezené. Pokud byl obsah kyseliny alfa-linole (cs)
  • The relatioship between different levels of n-6 and n-3 PUFA in chicken breast and thigh meat and organoleptic characteristics of meat was studied. Chickens were fed diets containing 1, 3, 5 or 7 per cent of oil made either of seeds of the linseed cultivar Atalante (A) with a high content of alpha-linolenic acid or of the cultivar Lola (L) with a predominating content of linoleic acid. Meat of chickens fed L showed better sensory characteristics than meat of birds fed A. When tissue contained n-3 PUFA more than 180 mg/100 g, i.e. in thigh meat when chickens fed 3 % or more A and in breast meat when fed 7 % A, a significant fishy odour and taste as well as a slight oily aftertaste were recorded. Texture, tenderness and juiciness of breast meat did not differ significantly (P>0.05) in groups fed different diets. Thigh meat in the group with 1 % A was significantly (P<0.05) more fibrous than in the group with 7 % L; however, there were no differences in texture among other groups. Thigh meat of chi
