“…The increase in tap density was 0.51 g/cc, 0.80 g/cc, 0.82 g/cc respectively when garlic incorporation was 0, 5 and 10 % which possibly could be due to the decreased expansion ratio with increased garlic incorporation and therefore more quantity of product could be accommodated. The bulk density too increased because of decreased expansion ratio with increased garlic incorporation which are in accordance to El-Samahy et al 2007and Bhattacharyya et al 1997. Guha et al (1997 reported that the combination of high temperature and high screw speed yielded a product with low density.…”

“…Sweet potato flour was processed using a single-screw extruder, with extrusion temperatures in zones 1 and 2 of 20 o C and 60 o C, respectively. The effect of flour moisture content (15,18 and 21%), barrel temperature in zone 3 (100, 120 and 140 o C) and screw speed (180, 210 and 240 rpm) on extrudate attributes was investigated using response surface methodology. Moisture content and extrusion temperature had a significant (p<0.05) influence on extrudates expansion.…”

“…Os índices de absorção de água estão relacionados com o grau de degradação das macromoléculas, o que interfere na capacidade das mesmas em absorver água [17,18]. GUHA, GUHA, ALI, BHATTACHRYA [18] extrusaram farinha de arroz sob extrusaram farinha de arroz sob condições de baixa rotação e temperatura e observaram que os valores de IAA apresentaram-se relativamente mais altos que em elevada rotação e temperatura.…”

“…WSI is related to the amount of soluble solids, which is often used as an indication of degradation of starch molecules, and dextrinisation (GUHUA; ALI; BHATTACHARYA, 1997;DOGAN;KARWE, 2003). It can also measure the degree of starch conversion during extrusion, which corresponds to the amount of soluble polysaccharide released from the starch granule (DING et al, 2005).…”
