Abstract

Royal jelly is a secretion produced from the hypopharyngeal glands of worker bees, which requires significant pollen reserves to stimulate gland secretion. The natural sources of food available to the hive during beekeeping season can greatly affect the quantity and quality of produced royal jelly. In this study, samples of royal jelly were collected throughout the beekeeping season, and their physical and chemical characteristics were analyzed to understand how natural variations in bee diet affect royal jelly production. Before each sample collection, the bees’ food reserves were removed from the experimental colonies so that the royal jelly was produced solely from natural sources. The results showed that the production was significantly lower during the summer months compared with spring and autumn. Additionally, the moisture, protein, fructose, and glucose content of fresh royal jelly also showed significant changes in the summer, and all physical and chemical characteristics decreased when the fresh samples were converted into dry matter. It seems that the quality of pollen entering the hives has a direct impact on the physical and chemical properties of the final product, highlighting the crucial role of available resources in stimulating bees to produce royal jelly.

与现有天然食物资源有关的蜂王浆生产和质量特征

蜂王浆是工蜂咽下腺产生的一种分泌物，需要大量的花粉储备来刺激腺体分泌。养蜂季节蜂巢的天然食物来源会极大地影响蜂王浆的产量和质量。这项研究在整个养蜂季节采集蜂王浆样本，分析其物理和化学特征，以了解蜜蜂食物的自然变化如何影响蜂王浆的产量。每次采集样本前，实验蜂群中的蜜蜂食物储备都会被移除，这样蜂王浆就只能从天然来源生产。结果显示，夏季蜂王浆的产量明显低于春秋两季。此外，新鲜蜂王浆的水分、蛋白质、果糖和葡萄糖含量在夏季也发生了显著变化，新鲜样本转化为干物质后，所有理化特性都有所下降。由此看来，进入蜂巢的花粉质量对蜂王浆最终产品的物理和化学特性有直接影响，这凸显了可用资源在刺激蜜蜂生产蜂王浆方面的关键作用。

期刊介绍： Resources (ISSN 2079-9276) is an international, scholarly open access journal on the topic of natural resources. It publishes reviews, regular research papers, communications and short notes, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and methodical details must be provided so that the results can be reproduced. There are, in addition, unique features of this journal: manuscripts regarding research proposals and research ideas will be particularly welcomed, electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Subject Areas: natural resources, water resources, mineral resources, energy resources, land resources, plant and animal resources, genetic resources, ecology resources, resource management and policy, resources conservation and recycling.
