Cucurbit root starches: isolation and some properties of the starch from Apodanthera undulata Gray

“…The gelatinization temperature was determined to be 64.5-67.5 °C by observation of staining with Congo Red. Gelatinization temperatures very close to this range have been reported for other cucurbit starches (Berry et al, 1975;Reichert, 1913).…”

Phenotypic variation in fruit and seed characteristics of buffalo gourd

“…Bemis et al (1) discussed the composition of the seed oil. The perennial plants also develop large tuberous roots which contain 55% starch on a moisture equilibrated basis (8). The distribution of the species, growth habits, morphology, and mode of reproduction were described by Bemis et al (1).…”

Buffalo gourd roots: chemical composition and seasonal changes in starch content

“…Although the major economic potential of the species lies in its ability to produce oil and protein rich seeds, Berry et al (1975) reported the presence of root starch in potentially commercial quantity. The plant develops a large perennial tuberous root, presumably used for water storage (Dittmer and Talley, 1964).…”

“…Three-year-old roots often reach depths of 1 to 2 m, with crown diameters of 20 to 30 cm. By an extractive procedure, 55% (dry weight basis) of the ground whole root was recovered as starch (Berry et al, 1975).…”
