Abstract

Proximate composition and the contents of free sugars, minerals, fatty acids, amino acids and in vitro digestibility of mixed pollen load were analyzed. The protein in pollen load per 100g was 25.2g, lipid 5.4g, non-fibrous carbohydrate 50.0g and fiber 10.4. Free sugars in pollen load, as dry basis g per 100g, was fructose 26.6g, glucose 13.1g, sucrose 0.2g, maltose 1.3g, melezitose 0.02g and F/G ratio was 2.0. The content of mineral in pollen load was in the order K > P > Mg > Ca > Fe > Na > Mn > Zn > Cu. Unsaturated fatty acid of pollen load was about 69.1% and polyunsalturated fatty acid being about 50.3%. The ratios of SFA : MUFA : PUFA and PUFA : SFA were 0.61 : 0.37 : 1.00 and 1.63 respectively. The total amino acid contained in pollen load 22,337.5mg/100g and total essential amino acid was 39.2% of the total amino acid. proline was the most abundant amino acid (2,824.7 mg/100g),followed by Glu, Leu, Asp, Val, Phe, Ile, Ala and Thr. E/T ratio of protein in pollen load was 2.03 ; protein score, 65.2(Lys) : A/E ratio(egg), 61.7(Lys) : amino acid score, 51.7% after 1hr and on non-fibrous carbohydrate was 80.6%. But that of protein was 67.3% after 1hr, 75.5% after 2hr.
