    Abstract: 發芽黃豆是目前漸趨流行的高營養食品,其加工製品也以強調低嘌呤為訴求。目前黃豆嘌呤之相關研究不少,但對於黃豆在發芽過程中其芽和胚乳的嘌呤含量變化,則少有人探討。當芽長度分別為1、3、5和7公分時,收其胚乳和芽來作一般分析與嘌呤含量分析,觀察其變化情形,結果發現,黃豆發芽達7公分後,豆芽與胚乳的質量比重大約是3: 7。黃豆胚乳的粗灰份、粗蛋白與總嘌呤含量(濕重)三者在發芽後都有一致的降低趨勢曲線,在1公分時急遽下降(總嘌呤含量降幅57%),芽長5-7公分時則趨穩定。至於黃豆芽的一般分析與嘌呤分析,都是呈下降的趨勢,3公分後則趨於緩和。黃豆全豆芽的總嘌呤曲線(濕重)則與胚乳曲線相似,嘌呤隨著芽長度而下降,降幅達57%。黃豆胚乳的乾重嘌呤含量與芽長度無關。黃豆芽1cm時的乾重嘌呤含量高達852 mg/100g,7cm時下降至504 mg/100g。然而發芽豆的胚乳與芽水份高達62%與90%,使得其黃豆芽嘌呤含量仍大幅下降。我們建議痛風的患者可限量食用長1公分左右之黃豆芽(82.3 mg/100g),或者可以摘除胚芽後再食用胚乳更佳(78.4 mg/100g) ;若欲食用豆芽菜,建議食用7cm以上去胚乳之黃豆芽,此時嘌呤含量較低(46.5 mg/100g)。
