Treatments varied on the amount of black rice flour. Ingredients were mixed, kneaded for 15minutes then baked for 30-40minutes at 120 degree celcius, packed and store in cool and dry place. The black rice cracker was medium purple-brown in color, slightly sweet and salty in flavor and moderate crunchy and rough in terms or texture. It was liked very much by consumer and more preferred than the commercial cracker. The physicochemical properties were water activity of 0.56, ash content of 2.19g/100g, moisture content of 6.09g/100g and crude protein of 9.69g/100g. The microbiological qualities were total aerobic place counts of <4300cfu/g and both <10cfu/g for yeast and mold counts. The black rice cracker can be sold for Php 34/100g of black rice cracker.xi, 54 p.: ill.
