The Development and Design Cold Bag’s Product from Rice Husk and Waste of Rice Berry and Black Rice Production. It is intended to bring rice husk in process to produce food in order to take advantage of the product design process and create a cooling pouch Master product for everyday use such as treating the refrigerant of a vaccine or medical medicine. Maintaining the temperature of breast milk is a source of design and development of refrigeration bag products. There are research methods starting from the study of the design of experiments. To be a guide to the implementation of the rice husk to bring out the cold storage plate and bring out the design of the product. The result of the master experiment with cold storage plates. Found that Paddy Husk has the right qualities due to the Density= 0.76 g./cm3 Moisture Absorption= 6.25% cracking resistance Modulus of Rupture: MOR= 7.690 MPa. and Modulus of Elasticity: MOE= 1064.77 MPa. which has a qualified property than Paddy husk from black rice. If you touch the water for a long time it has to absorb water and the inflation inside the skin which is inferior to the rice husk properties. The researchers put the extruded sheets from rice to a cold storage material in the pocket designed with a modern shape a material made of nylon fabric. On-off with zipper there is a strap and a box for inserting the pocket side. The bag has a compression plate from the surface of the 5 side rice to help protect the cold and reduce the use of synthetic chemicals which is environmental friendly.

The objectives of this research were to study the effect of the substitution of sinin rice flour to wheat flour in the crust of the flaky Chinese pastry (Kha-Nom Pia Kularb) on the physical quality the chemical composition and the consumer acceptance of the developed product. The ratios of sinin rice flour substituted for wheat flour (w/w) at 0:100 (control) 10:90 20:80 30:70 and 40:60 were studied. The results showed that increasing substitution levels caused darker purple lower cohesiveness and more difficult for shaping. Additional the higher level of substitution the more decreased of product’s size specific volume and lightness (L*) of crust and filling. According to the texture profile analysis when the ratio of sinin rice flour in the product increased the hardness springiness and cohesiveness of the product decreased while the chewiness increased. Sensory quality evaluated with 9-point hedonic scale by 55 panelists. The crust of product which was formulated using a ratio of sinin rice flour: wheat flour at 20:80 had liking score higher than the others with moderate liking score. Analysis of chemical compositions (100 g product) showed that the contents of moisture protein fat ash carbohydrate and dietary fiber as 16.37 7.09 26.30 0.62 49.62 and 2.27 g respectively. The total calorie was calculated as 463..54 Kcal/100 g. Furthermore this product provided anthocyanin 6.5 mg/100g (dry basis). Moreover consumer acceptance test with 120 consumers revealed that the overall liking of this product was like highly and 98.0% of consumers accept it besides 96.7% of them decided to buy it.
