Gac (Momordica cochinchinensis Spreng) is a plant that is gaining attention today in Gac amount of beta-carotene and lycopene, which is a substance that has the properties of free radicals and strengthens the immune system. Physical But the major problem is that the disease occurs during the production and post-harvest, especially fungi. Studies using natural extracts prevent the development of Gac to reduce postharvest diseases. The chitosan concentration of 1% extract of galangal concentration 5,000 ppm and extract freshwater concentrations of 5,000 ppm dipped results Gac within 1 week and 5 weeks, then harvest when Gac age of seven weeks the measure. Physical (Severity of disease Weight loss) to analyze the chemical changes. (Determination of phenolic compounds. And testing anti-oxidant in the seed coat) results showed that. Gac fruit during storage are losing weight gain. The amount of phenolic compounds and antioxidant activity in seed coat soared in the last 15 days during storage. And galangal extracts reduce the concentration of 5,000 ppm disease during storage of the Gac.
