Abstract

Pumpkin flour has high β-carotene, therefore, can be added to the noodle to alleviate vitamin A deficiency. Deterioration of β-carotene may take place during drying, proper control of the process to minimize the deterioration is necessary. The objective of the research was to study the β-carotene deterioration during drying process of the noodle and the physico-chemical properties of the cassava noodle that was enriched by pumpkin flour. The enrichment of the cassava flour was made by adding pumpkin flour various proportions 0, 5, 10 and 15 %. Noodle was sun dried for 8 hours, in cabinet dryer at 60ºC for 3 hours and in a two step cabinet dryer (60ºC for 2 hours followed by drying at 55ºC for 2 hours. The result showed that sun drying cause the greatest deterioration of β-carotene (46.24%). However, enrichment of pumpkin flour can improved the color, protein and β-carotene content of the noodle.

Abstract

Hypoglycemic property of soyprotein extract were evaluated in alloxan-induced diabetic rats. The objectives of this research were to evaluate the effects of soyprotein extract feeding on glucose concentration in both normal-cholesterol and hypercholesterol alloxan-induced diabetic rats. Twenty-eight male Sprague-Dawley (SD) rats (250-300 g) were provided and divided into four groups of seven rats. They were (1) Standard-Placebo (SP). (2) Standard-Alloxan (SA), Soyprotein-Alloxan (PKA) and (4) Hypercholesterol-Soyprotein-Alloxan (HPKA) groups. Three groups were diabetic induced by alloxan injection (80 mg/Kg of body weught by intra-muscular injection) and one group (SP) was injected with aquabidest (placebo). HPKA groups were fed hypercholesterol diet 2 weeks prior to the alloxan injection. SP and HPKA were fed soy protein diet for 28 days. Concentration of serum glucose were determined before injection (0 day), 1,7, 14, 21, and 28 days after injection. It was found that alloxan injection increased serum glucose concentration of SA, PKA and HPKA rats. In 28 days intervertion, soybean protein diet decreased the serum glucose concentration from 405 mg/dL to 201mg/dL (50%) in PKA and from 428 mg/dL to 210 mg/dL (51%) in HPKA groups, but standard diets (SP and SA) were failed to decrease the serum glucose of the rats.
