 note = {1988年8月(夏季)より1989年4月(春季)までの間, 白色卵殻鶏卵についてスーパーマーケット13店舗(供試鶏卵数1050個), 小売店4店舗(190個)褐色卵殻鶏卵についてスーパーマーケット8店舗(390個), 小売店8店舗(440個)より鶏卵を購入し, その卵質の季節的変化を調査した。卵質はハウユニット(以下HUと略す)と卵黄係数(以下YIと略す)を測定し比較した。HUは季節的変動が大きく, 夏季において有意に低い値を示し, 逆に, 冬季においては有意に高い値を示した。また, スーパーマーケットの方が小売店に比較してHUは高い値であった。夏季においてはHUのAA級とA級の占める比率は全体の50%以下であった。白色卵殻鶏卵のHUは褐色卵殻鶏卵のHUより有意に高い値であった。スーパーマーケットと小売店の鶏卵のYIにおいても季節的変動は大きく, 夏季において有意に低い値であった。, From August in 1988 to April in 1989,seasonal changes in interior quality of eggs collected from super markets and personal retail stores in Kyoto City were studied. White shell eggs were purchased from 13 super markets (1050 eggs) and from 4 personal retail stores (190 eggs). Brown shell eggs were purchased from 8 super markets (390 eggs) and 8 personal retail stores (440 egs). Significant seasonal variations were observed in haugh units of eggs. Haugh units was low in summer and high in winter. Haugh units of eggs from super markets were higher in relative to those from personal stores. In summer, ratio of AA and A egg grade based on haugh units were less than 50% of total eggs. Haugh units of white shell eggs were significantly higher than those of brown shell eggs. Significant seasonal variations were also observed in yolk index of eggs and yolk index was lowest in summer.},
