【摘要】:云南地區(qū)因其得天獨(dú)厚的自然條件,具有豐富的蜜源植物和礦產(chǎn)資源,產(chǎn)出了多種特色蜂蜜。對(duì)該地區(qū)的三種特色春蜂蜜(苕子蜜、橡膠蜜和石榴蜜)進(jìn)行了理化性質(zhì)的研究,結(jié)果表明三種蜂蜜在水分含量、電導(dǎo)率和粘度上均存在顯著性差異。利用高效液相色譜儀-示差折光檢測(cè)器(HPLC-RI)測(cè)定三種蜂蜜中的主要糖類,結(jié)果顯示石榴蜜中的葡萄糖含量最高[35.62g·(100g)-1],橡膠蜜中的果糖含量最高[41.03g·(100g)-1]。利用原子吸收光譜儀(FAAS)對(duì)三種蜂蜜中的13種礦質(zhì)元素進(jìn)行測(cè)定,結(jié)果顯示橡膠蜜中的礦質(zhì)元素總含量最高(437.34mg·kg-1),石榴蜜中的最少(167.24mg·kg-1)。將礦質(zhì)元素作為變量進(jìn)行主成分分析,可將三種蜂蜜相互分開。Cu,Zn和Na可作為苕子蜜的分辨標(biāo)記,Mg,K,Ca,As和Cd可作為橡膠蜜的分辨標(biāo)記,Fe,Mn,Ni和Cr可作為石榴蜜的分辨標(biāo)記。本研究的開展可補(bǔ)充云南特色蜂蜜的研究,為其開發(fā)利用提供理論依據(jù)。
[Abstract]:Because of its unique natural conditions, Yunnan has abundant nectar source plants and mineral resources, and produces many kinds of special honey. The physicochemical properties of three special spring honey (sweet potato honey, rubber honey and pomegranate honey) in Yunnan are studied. The results showed that there were significant differences in water content, conductivity and viscosity among the three kinds of honey, and the main sugars in the three kinds of honey were determined by high performance liquid chromatograph (HPLC) and differential refractive index detector (HPLC-RI). The results showed that the glucose content in pomegranate honey was the highest [35.62 g 路L ~ (100) g ~ (-1)], and the fructose content in rubber honey was the highest [41.03 g 路L ~ (100) g ~ (-1)]. 13 mineral elements in three kinds of honey were determined by atomic absorption spectrometer (AAS). The results showed that the content of mineral elements in rubber honey was the highest, and that in pomegranate honey was at least 167.24mg 路kg-1.The mineral elements were used as variables for principal component analysis. The three kinds of honey can be separated from each other. Cuzn Zn and Na can be used as the distinguishing markers of sweet potato honey, such as Mg-K, K, Ca, as and CD, which can be used as the resolution markers of rubber honey, such as Fe, mn, Ni and Cr, which can be used as resolution markers of pomegranate honey, which can be used to supplement the research of Yunnan characteristic honey. To provide theoretical basis for its development and utilization.
