An attempt has been made to prepare β‐cyclodextrin (CD) from cassava starch. Freshly prepared samples of cassava starch from M‐4 variety was treated with Standard cyclodextrin glycosyltransferase and the product obtained was converted to bromobenzene and chloroform chlathrates. The product was identified by non‐chromatographic spectrophotometric assay and by thermal decomposition behaviour. The bromobenzene β‐CD clathrate showed a distinct pattern of thermal degradation compared to that of both pure β‐CD as well as β‐CD chloroform chlathrates. The yield of the product isolated is approximately 10% (w/w) based on starch.
