Abstract:
Color rice share is the colorant which is included in the coat covering The black substance, purple or red is the accumulation of Anthocyanin which easily fall out from seeds coated. Parboiling rice is yield of paddy being processed under streaming and pressure methods. The main purpose is to extend the shelf life of white rice in commercial production. Under steaming and pressure condition Vitamin B1., Vitamin 82 and Vitamin B3 into endosperm increased affectias unpolished white rice and increased nutritional levels. This study consisted of 2. experiments Experiment 1 was conducted to compare the physical and chemical characteristics between
streaming and non-streaming of white rice (RD 49) color rice (Riceberry) and color glutinous rice (Khao daeng) under Completely Randomized Design (CRD). The experiment consisted of 3 replications consisting of 2 factors: included were 3 rice varieties. RD 49, Riceberry and Khao daeng using streaming and non-streaming process. Experiment 2 was the continuation of experiment 1 in order to study the effect of storage conditions as well as different shelf lifes of rice color shade during streaming and non-streaming processes. In the cooked value of the I'" experiment physical and chemical changs under long storage conditions and variant times were observed. The completely Randomized Design (CRD) was performed at 3 storage stases and random sampling in various periods, 1, 3 and 6 months. Percent moisture content were analyzed, as well as color measuring and Anthocyanin content in seed covered layer. water absorbent property and decomposition of the unpolished rice in alkaline, in experiment 1 it was found that the changes of the physical and chemnicat properties
