The sound was the seed (the first time) because the Crack 1st heat during roasting, making water changes to vapor, water (hydrolysis) causes a pressure towards the cell wall and the oxidation reactions of the Bora (carbohydrate oxidation) could cause carbon dioxide gas. Make the seam in the Middle the seeds. Crack seed sounds. The color of the seed is changed from yellow to pale yellow to brown sugar, which is caused by the change of the total sugar molecules. (Polysaccharides) smoke that occurs during this period will have the color grey. When there is more evaporation of water inside the cells (dehydration), rigid structure (woody structure) of the seeds will be broken down. Make the seeds swell. Expand a larger seeds, 40-60 per cent by volume, there are greater brittleness seed (seed density decreased). Volatile substances (volatile substance) and membranes seeds Brown will come off as tiny flakes (chaff).
