Abstract

Germinated brown rice is malting rice with intact embryo of 0.5-1.0 mm which has been reported of increasing beneficial bioactive products for human such as gamma amino butyric acid (GABA). Studies on preparation of enhancing GABA in germinated brown rice and its products were conducted during 2008-2010 at Pathum Thani Rice Research Center. Results indicated that appropriate method was malting of selected healthy brown rice in a closed container at room temperature for 20 hours after the seeds being washed with clean water and steeped for 4 hours. This freshly malting rice can be used for making blended drinks of germinated brown rice by pre-boiling with intermittently stirring the mixture of ingredients as germinated Khao Dawk Mali 105 : germinated black glutinous rice: over night steeped soy bean: roasted white sesame: water at a ratio of 1: 0.5 : 0.3 : 0.3 : 20 by weight for 20 minutes. Filtering the mixtures twice and adding 5 g of sugar per 100 ml of the mixtures. Processing of instant germinated brown rice was also conducted by pre-preparation of soy milk from a mixture of overnight soaked soybean: roasted white sesame: water at a ratio of 1 : 0.8 : 14 by weight. Rice starch mixture was then prepared by mixing germinated Khao Dawk Mali 105 : germinated black glutinous rice: soy milk at a ratio of 7:3:9 by weight and wet milling. The mixture was dried with a double drum drier then ground to fine powder. Eight grams of germinated rice powder were then mixed with 5 g fine sugar, 4 g maltodextrin, and 2 g non dairy cream packed in aluminium foil sachet. Another experiment was conducted at Ubon Ratchathani Rice Research Center using cooked germinated Khao Dawk Mali 105 and water at a ratio of 1 : 1 by weight. The mixture was slurred and drum dried prior to ground into powder. The powder was then packed with pre-cooked soy bean and job tear powder which were prepared by over night soaked and steamed cooked before drum dried and ground to powder. The ingredient contained 7 grams of dehydrated germinated brown rice, 2 g dehydrated soy bean, 2 g dehydrated Job’s tear, 6 g non dairy cream, 4 g dairy powder and 10 g sugar.
