Abstract: The experiment was conducted to study the qualities and ω6/ω3 PUFAs of two brands of eggs sold from a supermarket in Beijing, Tianjin and Baoding city in order to compare the egg qualities and ω6/ω3 PUFAs of ordinary eggs with native eggs. The results showed that:(1)The contents of total fatty acids is 14.20-24.98 g/100g in ordinary eggs, 14.64-25.41 g/100g in native eggs; the contents of ω6 PUFAs is 2.16-3.99 g/100g in ordinary eggs, 2.51-4.87 g/100g in native eggs; the contents of ω3 PUFAs is 0.19-0.29 g/100g in ordinary eggs, 0.24-0.37 g/100g in native eggs; the ratio of ω6/ω3 is 11.18-14.45 in ordinary eggs and 10.56-13.23 in native eggs of Beijing, Tianjin and Baoding. The ratio of ω6/ω3 of ordinary eggs from Beijing city was significantly lower than that from Baoding city(P<0.05)and was lower than that from Tianjin city(P>0.05); The ratio of ω6/ω3 of native eggs from Beijing city was lower than that from Tianjin city and Baoding city(P>0.05);(2)For the ordinary egg, egg weight from Baoding city was significantly higher than that from Beijing and Tianjin city(P<0.05); The difference of egg shape index and yolk proportion from three cities was not significant(P>0.05). Haugh units from Beijing was significantly higher than that from Tianjin and Baoding city(P<0.05).The native eggs from Beijing city, egg weight and yolk index was significantly higher than that from Tianjin and Baoding city(P<0.05); Egg shape index from Baoding city was significantly higher than that from Beijing and Tianjin city(P<0.05); Haugh unit from Baoding was the highest, significantly higher than that from Tianjin and Beijing(P<0.05); Egg yolk color and egg yolk proportion from Beijing and Tianjin city was significantly higher than that from Baoding city(P<0.05).
