Effect of Solar Drying Process on Bioactive Compounds and Antioxidant Activity in Vitro of High Andean Region Bee Pollen

Chemical Engineering Transactions, 2019
Bee pollen is a hive product of common consumption with a known and remarkable content of bioactive and functional compounds, namely carotenoids and phenolic compounds. The bee pollen from the Colombian High Andean region has a prominent content of these

The collection of pollen by bees

Plant Systematics and Evolution, 2000
Bees require pollen for their reproduction and pollen comprises the basic larval food for bees. Most bees acquire pollen passively during flower visitation, but female bees may also collect pollen actively with the aid of various structural and behavioral adaptations.

The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

PLANTS, PEOPLE, PLANET, EarlyView.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...

Quality Assessment of Bee Pollen: A Cross Sectional Survey in Bulgaria

Journal of Food Quality and Hazards Control, 2018
Background: Due to its nutrient content, a variety of spoilage microorganisms can grow in bee pollen, especially when handling practices are not appropriate. So, this survey was designed to assess the physicochemical and microbiological properties of bee

Determination of Ascorbic Acid, Total Ascorbic Acid, and Dehydroascorbic Acid in Bee Pollen Using Hydrophilic Interaction Liquid Chromatography-Ultraviolet Detection

Molecules, 2020
Ascorbic acid (AA) is one of the essential nutrients in bee pollen, however, it is unstable and likely to be oxidized. Generally, the oxidation form (dehydroascorbic acid (DHA)) is considered to have equivalent biological activity as the reduction form ...

Making Learning Personally Relevant: Sensemaking Assets Used in Families' Discussions While Using a Pollinator‐Focused Mobile Augmented Reality App

Science Education, EarlyView.
ABSTRACT This study seeks to better understand the unique sensemaking assets that rural families weave into their outdoor learning experience while using a location‐based mobile app focused on healthy habitats for solitary bees. The project included mobile augmented reality (AR) technologies, which are increasingly used as educational tools at informal

Effect of wall-disruption on nutrient composition and in vitro digestion of camellia and lotus bee pollens

Food Science and Human Wellness
The nutrient digestion, absorption and biological activity of bee pollen may be limited due to the complex pollen wall. Here, the effect of superfine grinding technology on the release of nutrients from bee pollen were investigated, and their antioxidant

Bee pollen and its pharmacological properties

Communications Faculty of Science University of Ankara Series C Biology Geological Engineering and Geophysical Engineering, 2018
Bee pollen is a natural honey bee product that is considered a valuable resource for nutrients and energy. It is a health-enhancing value because of its wide variety of primary and secondary plant metabolites and enzymes and co-enzymes. Therefore, bee pollen is especially appreciated by consumers and used as an alternative drug.

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is
