Abstract

Indonesia is known as a country rich in species of seaweed. The most important components of seaweed are iodine and dietary fiber. Eucheuma cottoni is one species of seaweed that can be used as a source of iodine and dietary fiber. Iodine deficiency can cause several diseases also known as IDD (Iodine Deficiency Disorder), while deficiency of dietary fiber can cause some degenerative diseases. This research is taken to develop the utilization of Eucheuma cottoni as an ingredient in the making of jam and “dodol” (Indonesian traditional snack food). The best ratio of seaweed and sugar for jam production was 37:63, while the best ratio of seaweed and glutinous flour in making dodol was 5:2. The addition of seaweed on jam and dodol formula increased their iodine and dietary fiber contents. The iodine content of jam and dodol was 17.79 and 19.57 µg/g, respectively. The dietary fiber content of jam and dodol was 5.75 and 5.63%, respectively. Key words : Disorder, dietary fiber, dodol, jam, seaweed

Abstract

Sweet potatoes have a fairly diverse varieties and the difference in varieties is assumed to influence the starch physicochemical properties. The objective of this research was to optimize the sweet potato vermicelli production using a cooking-forming extruder. The starch characterization included proximate analysis, starch content, amylose content and gelatinization profile. Sweet potato vermicelli was made with the starch of sweet potaoto Ace variety. Meanwhile, process and formula optimization was carried out using Response Surface Methodology (RSM). The amount of starch used was in the range of 62.5–69.0 g, the amount of water was 31.0–37.5 g, extruder temperature of 80-90°C and screw rotation of 90-120 rpm. The starch of sweet potato Ace variety had the highest level of carbohydrate, total starch and amylose (99.16, 86.91, and 8.77% db, respectively). It also had the most excellent cooking endurance as shown by the lowest breakdown viscosity (5183.33 cP), and the best tendency of retrogradation as shown by the highest setback viscosity (1328.00 cP). The optimum combination for the vermicelli making was 65.2 g of starch, 34.8 g of water, extruder temperature of 85°C and screw rotation of 115 rpm. The sweet potato vermicelli from the optimum condition resulted in 20.85% actual cooking loss and 164.98% elongation. Process improvement with freezing and fan drying of the vermicelli produced a better quality of vermicelli with 12.90% cooking loss and 196.42% elongation.
