Artificial rice from Gracillaria sp. as functional food to prevent diabetes

Abstract

Seaweed Gracillaria sp. was one of the local potentials of West Java-Indonesia, this seaweed was easily cultivated, but currently underutilized. Therefore, processing was very important to increased value added of seaweed. The purpose of this research were characterize and determine antialphaglukosidase activity of Gracillaria sp. seaweed as raw material for artificial rice. The research method used a Complete Randomized Design (CRD) of two factors with continued testing of Duncan and Kruskal Wallis. The addition of agar flour influenced the water content, ash, fat and protein content on artificial rice. The result of organoleptic test showed that addition of agar flour for artificial rice gave significant effect on color, odor and texture. The resulting artificial rice has a moisture content of 9.9-13.7%, ash content of 1.1-4.3%, fat 0.3-3.7%, protein 2.7-5.9%, carbohydrate 77.7-80.3%, fiber 0.11-0.95%, and tannin 0.11-0.20%.

Characterization Properties of Extruded Analog Rice Developed from Arrowroot Starch with Addition of Seaweed and Spices

“…According to the fiber content of fresh and dried in Gracilaria spp. seaweed reaches 11.2 % and 27.48 % approximately (Purwaningsih et al, 2020;Rasyid et al, 2019). The fiber consists of resistant starch and non-starch polysaccharide (Holscher, 2017).…”

“…(Anggraini et al, 2016), and cornflour (Zea mays L.) and Gracilaria spp. seaweed (Purwaningsih et al, 2020), predicted the glycemic index of rice analog from modified arrowroot starch (Damat et al, 2021).…”

“…seeds, tofu pulp (Putri and Sumardiono, 2020), from sago and red beans (Phaseolus vulgaris L.) (Wahjuningsih et al, 2020), and analog rice from corn flour and seaweed grass (Gracilaria sp.) (Purwaningsih et al, 2020). However, there are no studies on analog rice made from a mixture of modified arrowroot starch using the heat moisture treatment (HMT) method and corn flour with seaweed porridge as a source of antioxidants.…”
