这项研究的目的是比较物理化学,微生物,和单花蜂蜜的抗氧化特性,多花蜂蜜,蜜露,和干草草甸蜂蜜。干草草甸是半天然草地类型,具有丰富的花卉多样性。传粉者的重要资源。草原是5月和6月获得的春季花蜜蜂蜜的来源。含水量,糖(果糖,葡萄糖,蔗糖,海藻糖,松三糖,麦芽糖,erlose,松二糖,和棉子糖),电导率,酚类含量(没食子酸,原儿茶酸,4-羟基苯甲酸,香草酸,绿原酸,咖啡酸,对香豆酸,迷迭香酸,杨梅素,quercitin,木犀草素,山奈酚),颜色,粘度,并对所有蜂蜜样品进行了微生物学特性分析。草地蜂蜜(21.50mg/100g)和蜜露(30.49mg/100g)的总多酚含量显着,金合欢(0.08mg/100g)和油菜蜂蜜(0.14mg/100g)的总多酚含量不那么显着。所有样本都是微生物安全的,所有样品的标准板计数(SPC)值均<10cfu/g,但是草原蜂蜜的微生物质量最高:33.3%的样品没有微生物,50.0%,酵母的存在低于限制,和16.7%,酵母和霉菌在限制范围内,不符合其他类型的蜂蜜的情况。用主成分分析(PCA)获得的统计分析结果表明,草地蜂蜜与其他类型的蜂蜜之间存在重大差异。
The aim of this study was to compare the physicochemical, the microbiological, and the antioxidant characteristics of unifloral honey, polyfloral honey, honeydew, and hay meadows honey. Hay meadow is type of semi-natural grassland with a great floral diversity, an important resource for pollinators. Grasslands are the source of the spring nectar honey obtained in May and June. Water content, sugars (fructose, glucose, sucrose, trehalose, melezitose, maltose, erlose, turanose, and raffinose), electrical conductivity, phenolic content (gallic acid, protocatechuic acid, 4-hydrxybenzoic acid, vanilic acid, chlorogenic acid, caffeic acid, p-coumaric acid, rosmarinic acid, myricetin, quercitin, luteolin, kaempferol), color, viscosity, and microbiological characteristics were performed for all samples of honey. The total polyphenols content was significant for grassland honey (21.50 mg/100 g) and honeydew (30.49 mg/100 g) and less significant for acacia (0.08 mg/100 g) and rape honey (0.14 mg/100 g). All samples were microbiologically safe, and standard plate count (SPC) values were <10 cfu/g for all the samples, but the grassland honey had the highest microbiological quality: 33.3% of samples without microorganisms, 50.0% with the presence of yeast under limit, and 16.7% with yeast and mold under limit, a situation that does not meet other types of honey. The results of statistical analysis obtained with principal component analysis (PCA) showed a major difference between the grassland honey and the other types of honey.
