Studies on the quality of commercial honey. I. A simple method for determination of sugars in honey

, : Studies on the quality of commercial honey. I. A simple method for determination of sugars in honey. Journal of the Japanese Society of Food and Nutrition 23(6): 374-378

A 3,6-dinitrophthalic acid colour reaction was used for determination of reducing sugars. Charcoal column chromatography separated honey sugars into the following 3 fractions: (1) aqueous eluate (glucose and fructose); (2) 7% ethyl alcohol eluate (disaccharides); (3) 50% ethyl alcohol eluate (higher oligosaccharides).

Recently, invertebrate models have been widely used for the study of innate immunity. Nematodes are novel potential candidates because of the experimental advantages of Caenorhabditis elegans. However, whether nematodes have active immune response...
