Pollen is a source of nutrients for honeybees (Apis mellifera L.) and suitable human consumption as well. In our research, multiresidue method pesticide determination was developed validated the bee pollen matrix. 247 components met validation criteria limit detection, quantification, linearity, interday repeatability. Average recoveries varied between 70 120% except 14 analytes, which were corrected during on-going validation. The matrix effect strong certain required use matrix-matched...
The chemical composition of bee pollens differs greatly and depends primarily on the botanical origin product. Therefore, it is a crucially important task to discriminate different plant species. In our work, we aim determine applicability microscopic pollen analysis, spectral colour measurement, sensory, NIR spectroscopy, e-nose e-tongue methods for classification five origins. Chemometric (PCA, LDA) were used classify loads by analysing statistical pattern samples independent combined...
Sustainability is becoming increasingly important in the world we live in, because of rapid global population growth and climate change (drought, extreme temperature fluctuations). People developing countries need more sustainable protein sources instead traditional, less meat, fish, egg, dairy products. Alternative (plant-based, such as grains (wheat, rice sorghum), seeds (chia, hemp), nuts (almond, walnut), pulses (beans, lentil, pea, lupins), leaves (duckweed), well mycoproteins,...
Bee pollens are potential functional food ingredients as they contain essential nutrients and a wide range of bioactive compounds. The aim this study was to investigate the effects enrichment with monofloral bee on nutritional properties, techno-functional parameters, sensory profile, consumer preference biscuits. Biscuits were prepared according AACC-approved method by substituting wheat flour rapeseed (Brassica napus L.), phacelia (Phacelia tanacetifolia Benth.) sunflower (Helianthus...
Abstract In our study, Central and Eastern European bee pollens of different botanical origins were compared, based on their antioxidant color properties. Total phenolic content (TPC), total flavonoid (TFC), in vitro capacity (by FRAP, CUPRAC, ABTS⋅ + DPPH⋅ assays) determined spectrophotometrically. Besides, Relative Antioxidant Capacity Indexes (RACI) calculated. CIELAB parameters (L*, a*, b*, chroma) by using a tristimulus‐based instrument. Potential correlations between the investigated...
In recent decades, there has been an increasing consumer demand for the so-called superfoods, accompanied by a growing scientific interest. our work, sixteen commercial nutraceuticals of different product categories, including powders cereal grasses, vegetables, fruits, microalgae, aquatic plant, and herbs, were analyzed to compare their nutritional properties volatile profile. Some samples, especially spirulina, chlorella, duckweed powders, rich in protein; however, amino acid composition...
ABSTRACT The volatile profile of bee pollen samples from Central and Eastern Europe was investigated by headspace solid phase microextraction (HS‐SPME) combined with gas chromatography–mass spectrometry‐olfactometry (GC–MS‐O). Sampling conditions were optimized for the extraction volatiles. Pollen odorants extracted six different fiber coatings, five various times, three diverse temperatures differing desorption times. most effective combination application...
Due to its nutritional value, physiological effects and unique aroma, honey is one of our widely consumed foods, used for sweetening. There are several regulations concerning the composition analysis honey, which specifications guidelines Hungarian Food Codex authoritative in Hungary. In present study, color characteristics nutrient domestic foreign honeys examined. Our intention was review physical chemical different origin marketed As a point interest, obtained from market also Pollen less...
Tápértékének, élettani hatásainak és egyedi aromájának köszönhetően a méz széles körben fogyasztott, édesítésre használt élelmiszerünk. A mézek összetételére vizsgálatára vonatkozóan számos szabályozás létezik, amelyek közül hazánkban Magyar Élelmiszerkönyv előírása irányelvei mérvadók. Tanulmányunkban hazai külföldi színjellemzőit beltartalmi összetételét vizsgáltuk. Szándékunk volt áttekinteni forgalmazott, különböző eredetű fizikai kémiai jellemzőit. Érdekességképpen egy külföldön, piaci...
