Pollens have been known to possess various biological properties. Therefore, pollens have been extensively used in functional food, folk medicine, and beverage industry to improve human health. This study was conducted to establish the optimized protocol for cytoplasm isolation of bee pollen. Data of biochemical parameters and fatty acid profiles were obtained from pollens of Acorn and Darae (Actinidia arguta). Contents of crude protein and crude fat were 24.1% and 11.8% in Acorn pollen, and those of Darae pollen showed 35.8% and 8.7% in crude protein and crude fat respectively. Also after lyophilizing of Acorn pollen, content of crude protein was increased to 26.5%. Main fatty acids were palmitic acid (C16 : 0), oleic acid (C18 : 1), linoleic acid (C18 : 2) and linolenic acid (C18 : 3) in bee pollen. Linoleic acid (37.3%) was dominant fatty acid in Acorn pollen that is one of essential fatty acids. Linolenic acid (48.3%) was dominant fatty acid in Darae pollen that is a polyunsaturated fatty acid. The proportion of unsaturated fatty acids to total acid content was 73.2% in Acorn and 63.2% in Darae pollen, and especially that of polyunsaturated fatty acids was higher than 55%.
