    摘要:

    對添加營養(yǎng)素提高蘋果酒中的酯類物質(zhì)含量進(jìn)行了初步研究,。通過Plackett-Burman試驗從氨基酸類,、生長因子類和維生素類營養(yǎng)素中篩選出對蘋果酒總酯質(zhì)量濃度影響顯著的因素為亮氨酸、谷氨酰胺,、吡哆醇和氯化鋅,。利用最陡爬坡試驗得到4個因素的中心點分別為:亮氨酸35 mg/L、谷氨酰胺90 mg/L,、吡哆醇0.3 mg/L和氯化鋅1.25 mg/L,。利用二次旋轉(zhuǎn)中心組合試驗對4個因素進(jìn)行了優(yōu)化,得到最佳營養(yǎng)素組合為:亮氨酸34.8 mg/L,、谷氨酰胺84 mg/L,、吡哆醇0.24 mg/L和氯化鋅1.30 mg/L,在此最優(yōu)條件下蘋果酒的總酯質(zhì)量濃度可達(dá)到5.29 mg/L,。

    Abstract:

    The improvement of esters content in cider by adding the nutrients into the apple juice during fermentation was investigated. By conducting the Plackett Burman experiment design, the factors affected 〖JP2〗the production of esters significantly, were selected, i.e. leucine, glutamine, pyridoxine and zincchloride. Subsequently, the steepest accent design was conducted to determine the central points of the four selected factors. The central points were 35 mg/L for leucine, 90 mg/L for glutamine, 0.3 mg/L for pyridoxine and 1.25 mg/L for zincchloride. The factors were optimized further by conducting the quadratic rotating combined design experiment. The optimizing condition was that adding 34.8 mg/L of leucine, 84 mg/L of glutamine, 0.24 mg/L of pyridoxine and 1.30 mg/L zincchloride to the fermentation liquor. Under this optimizing condition, the content of esters in the final cider achieved 5.29 mg/L.
