RESUMO
Aim: The objective of the study was to develop and characterize the properties of sago (sabudana) from cassava based reconstituted dry starch with addition of pre-gelatinized starch and wet starch as binders.Methodology: The dry starch was soaked for 12 hrs at 30 % concentration and then sago was prepared at 40% moisture content with addition of pre-gelatinized starch and wet starch as binders in different treatment combinations. Results: The sago developed from the combination of reconstituted dry starch (75%) and wet starch (25%) had an optimal commercial size (3.36 mm) and shape (sphericity value, 76 %). The swelling power (5.98%) was high in reconstituted dry starch sago and solubility (13.42 %) was high in wet starch sago without the addition of any binders. The increase in cooking time (10.37%) and decrease in cooking loss (1.73%) were observed for sago developed with pre-gelatinized starch as binder. The lowest oil absorption index (0.45 g g-1) was noticed for sago prepared with wet starch as a binder. The storage modulus was comparatively lower for sago paste prepared using wet starch and thus the sago gel behaved like a dilute solution with increase in storage modulus and phase angle. Interpretation: The physico-functional properties of the cassava -based reconstituted dry starch sago can be improved by adding wet starch as a binder due to less retrogradation rate. Further, the addition of pre-gelatinized starch as a binder with reconstituted cassava dry starch can reduce the cooking loss in sago.
RESUMO
We report a patient with a phytobezoar extending from the stomach through the small intestine to the cecum. The patient presented with acute intestinal obstruction and bezoar was suspected at exploration. The specimen showed two masses of cotton fibres connected with a long string of variable thickness.
