“…Pollen collection varies widely among different seasons and is affected by the availability of major pollen sources [23,[34][35][36][37][38][39]. In the Al-Ahsa Oasis, Taha [36], Taha and Al-Kahtani [40], and Taha et al [41,42] observed that over 69% of the studied pollen loads were harvested during spring and winter.…”

“…In the Al-Ahsa Oasis, Taha [36], Taha and Al-Kahtani [40], and Taha et al [41,42] observed that over 69% of the studied pollen loads were harvested during spring and winter. Additionally, the nutritional value of bee pollen is reportedly affected by the harvest season [23,37,43,44]. Harvesting pollen loads collected from a specific botanical origin is a complicated process that takes time and effort.…”

Seasonal variations in the fatty acid (FA) compositions of pollen loads collected from the Al-Ahsa Oasis in eastern Saudi Arabia throughout one year were determined to identify the optimal season for harvesting bee pollen rich in essential fatty acids (EFAs) and unsaturated fatty acids (UFAs). The highest values (%) of lipids, linolenic acid (C18:3), stearic acid (C18:0), linoleic acid (C18:2), arachidic acid (C20:0), the sum of the C18:0, C18:1, C18:2, and C18:3 concentrations, and EFAs were obtained from bee pollen harvested during autumn. The maximum values (%) of oleic acid (C18:1), palmitic acid (C16:0), UFAs, and the UFA/saturated fatty acid (SFA) ratio were found in bee pollen harvested during summer. The highest concentrations (%) of behenic acid (C22:0), lignoceric acid (C24:0), and SFAs were found in bee pollen harvested during winter. Bee pollen harvested during spring ranked second in its oleic, palmitic, linolenic, stearic, arachidic, behenic, and lignoceric acid concentrations and for EFAs, UFAs, and the UFA/SFA ratio. The lowest SFA concentration was found in bee pollen harvested during summer. Oleic, palmitic, and linolenic acids were the most predominant FAs found in bee pollen. It was concluded that the FA composition of bee pollen varied among the harvest seasons due to the influence of the dominant botanical origins. We recommend harvesting pollen loads during spring and summer to feed honeybee colonies during periods of scarcity and for use as a healthy, nutritious food for humans.

“…Pollen pellet is not a bee product exactly, but it is referred to bee-keeping products (Negrão and Orsi, 2018). The pollen collected by the bees is called pollen pellets, as the bee carries it in the baskets of its legs.…”

Increased man-caused impact, imbalance in diets lead to diseases, premature aging and life shortening. To overcome this imbalance, there is an active search for raw materials containing the physiologically functional ingredients necessary for human health or the raw materials containing biologically active substances, vitamins, mineral substances. To enrich traditional recipes with these components and to give functional purpose to products of mass demand, it is advisable to include, oat meal (talcan) and pea meal into the bee-keeping products composition which have a high biological value. Standard methods for analyzing the quality of raw materials and confectionery were used for the study, as well as modern instrumental methods for analysis, such as high performance liquid chromatography and atomic absorption spectrophotometry. The physical and chemical and quality parameters of talcan, pollen pellet, honey and pea meal (by-product of pea processing) have been studied as well as formulas of confectionery products with the indicated components have been developed. The national confectionery dish chak-chak, which recipe included talcan, pollen pellet and honey, contained an increased amount of vitamins and minerals in comparison with the control sample. It has been experimentally proved that the inclusion of these components into the formula allowed obtaining a product with a high nutrient content. It was also found that with the inclusion of pollen pellet into the marshmallow recipe, the amount of vitamins and minerals in the developed product increases. The analysis of the results showed that the enrichment of sugar cookies with pea forage leads to an increase in the content of protein, carotenoids and vitamins. It is established that in comparison with the control sample the content of mineral substances increased.

“…Bee forage types affect the quantity and quality [42] of honey yield obtained per colony [30,31,33,43]. According to the sampled beekeepers, the existence of some special honeybee floras in the study district results in the production of goodquality and high-quantity honey and increases the frequency of harvests.…”

The contribution of beekeeping is perhaps one of the most important income-generating activities for millions of smallholder farmers in Ethiopia. This study was intended to assess beekeeping practices and potential in three districts of Afar Region, northern Ethiopia. Primary data were collected from 120 respondents proportionally selected from each district. Semi-structured questionnaire were employed to collect the primary data. Focus-group discussion was also used to support interpretation of the interview data. Basically, descriptive statistics were used to analyse the data. All respondents use traditional honey production system despite some recent trials. The mean live colony ownership of the sample beekeepers is 10.08 colonies per household, with a maximum ownership of 62 colonies. The study showed that the annual honey production per beehive varies from 4 to 17 kg, with a mean production of 9.66 kg. The majority of the respondents harvest two times per year, while 18%, 19%, and 14.2% of the respondents harvest three, four, and five times per year respectively. This might be due to the special floral calendar of tropical plants found in the areas. 67.5% of respondents supplement their colonies during dry season. Producers travel more than seven kilometres to sell their honey. On average, beekeepers sell 77.86 kg per year individually, with a range of 0 to 353 kg. The main constraints of honey production in the area are recurrent drought, poor extension service, lack of access to improved technology, deforestation, etc. Therefore, it requires intervention to change the old beekeeping practices through training and introducing improved production systems.
