EXTRACTION AND CHARACTERISATION OF CELLULOSE NANOCRYSTALS FROM PINEAPPLE PEEL

The potential of pineapple peel as a source of cellulose nanocrystals was Treatments evaluated.Peels skin from fresh-cut fruit was used as raw material.These residues were purified to remove pigments, lipids and hemicellulose, and a bleaching process for delignification was carried out for 4-6 h.All resulting products were characterised for their l

Background: The viability of any pedicled flap depends upon its vascularity.When a flap Christmas Stocking is dissected it becomes relatively ischaemic.Ultimately, the viability of the flap depends on the vessels incorporated in the pedicle and their perfusion capacity.There are different techniques to evaluate the blood supply of a flap.Aims: This
