15.2.1 the trial found that the brightness of the sprouts through the Purifier from lemon juice, citric khaokrot with minimal negative-12.84 and after 24 hours and 48 hours respectively. The value is negative, there will be a little brightness, the color white is nearby the most from L * a-color system *-* b, where L is the luminance value – L * Represents white + L * represents black. For example the sprouts through the bleach from the lemon juice citric doikrot is negative, there is little more than another 4 white example because in the lemon juice, citric acid content than the Division with orange juice. Pineapple juice Citric acid which has gum, water, aggressive. Acid can inhibit the reaction occurred, Brown. Acid pH values. adjusts the pH value, a lower deterioration of enzymes in sprouts and stopped working. So it is not a brown in sprouts.15.2.2 from experimental microbial quantification in bean sprouts found that colonies of sprouts through the bleach from lemon juice. Microbial counts 89 and 76 appearance colony at concentration 1:100 after disposing the sprouts at 48-hour and 24-hour pH value of lemon 2.5 pH low value, which will cause the growth of pathogenic microorganisms due to reduced functioning of the enzyme is inhibited. When the number of pathogenic microorganisms is reduced, therefore, affect reaction to occur with less Brown.
