The study aimed to :1) create a standard formula for frozen rice berry flour Khnom Tien 2) study the defrosting process using a microwave and 3) evaluate consumers’ acceptance. The physical properties sensory evaluation chemical composition and microbiological quality were studied. To create the formula substitution of riceberry flour for sticky rice flour at 20 30 and 40% weight per weight were used and studied. It was found that Khnom Tien with 20% of rice berry flour in substitution for sticky rice flour was accepted most on appearance smell taste and overall appearance but texture (stickiness) was accepted at “a little level”. To improve the texture arrowroot flour was added to increase amylopectin. The result showed that the addition of 7.5% arrowroot flour for the total flour weight was most accepted in all aspects. The results of the physical quality analysis indicated that the stickiness value was to that of the basic formula. The standard formula of riceberry Khnom Tien contained 80% sticky- rice flour 20 % of rice berry flour to sticky- rice flour (w/w) 7.5% of arrowroot flour to the total flour weight(sticky rice flour and riceberry flour weight)500g palm sugar and 800g Gnaphalium affine juice. Microwaving at 600 watts for 2 minutes or at 800 watts for 1.30 minutes could be used in defrosting Khnom Tien. The product could be kept for 60 days at -18 ºc; none of the microorganism yeast or mold was found. One hundred grams of the product provided 249.4kcal energy 5.17g carbohydrate 1.12 fat 3.66g protein 0.41g fiber and 0.81mg anthocyanin. The consumers accepted the product at “much” and “moderate” levels; 95% of them were interested in buying the product sold in a department store/ supermarket at 36 baht for one plastic box containing 4 pieces of Khnom Tien.

The study is to create a standard recipe of Kanom Tong Pub made from Riceberry flour and to study changes during storage and consumer product acceptance. Three basic recipes were used. Tester sampling plan has been made to evaluate the tester sense from appearance color aroma taste texture and overall satisfaction. The testers most satisfied the first recipe in all aspects of which it uses Riceberry flour to replace normal flour made from rice in the amount of 100 percent. It consists of Riceberry flour 130 grams wheat flour 110 grams tapioca flour 220 grams sugar 235 grams baking powder 1 gram salt 2 grams black sesame seeds 10 grams coconut milk 550 grams and 100 grams of weight contains energy 464.15 kilocalories protein 5.76 grams fat 12.85 grams carbohydrate 77.49 grams dietary fiber 0.87 grams and Anthocyanin 0.92 milligrams. Study of changes during 90-day storage reveals product from Riceberry flour is still safe for consumers. 67 percents of testers rate very like to like moderately. Customer acceptance study show that most testers accept it because of its appearance color aroma taste and overall satisfaction and rate as highest level of satisfaction.
