NOVELTY - Extracting liquid phytase involves uniformly mixing fermentation liquid medium with malt extract. The obtained mixture is fermented at 28-35 degrees C for 15-24 hours under stirring speed 120-180 revolutions per minute. The obtained fermentation broth is passed through diatomite filter paper under 0. 14-0.24 MegaPascals pressure to obtain fermented crude enzyme solution. The obtained fermented crude enzyme solution is processed by high pressure pulse frequency (HPEF), where the obtained HPEF crude enzyme solution is passed through an ultrafiltration membrane to obtain concentrated enzyme solution.    USE - Method for extracting liquid phytase (claimed).    ADVANTAGE - The extracted liquid phytase can be effectively stored at room temperature for 12 months without affecting its activity loss rate, in a simple, convenient, economical and environmental-friendly manner.    DETAILED DESCRIPTION - Extracting liquid phytase involves uniformly mixing fermentation liquid medium with malt extract. The obtained mixture is fermented at 28-35 degrees C for 15-24 hours under stirring speed 120-180 revolutions per minute. The obtained fermentation broth is passed through diatomite filter paper under 0. 14-0.24 MegaPascals pressure to obtain fermented crude enzyme solution. The obtained fermented crude enzyme solution is processed by high pressure pulse frequency (HPEF), where the obtained HPEF crude enzyme solution is passed through an ultrafiltration membrane to obtain concentrated enzyme solution. 5-12% Stabilizer is added to the concentrated enzyme solution, where pH of the prepared enzyme mixture is adjusted using lactic acid between 2.5-5.5. The prepared enzyme mixture is passed through sterilized filter membrane to obtain stable liquid phytase. The stabilizer comprises 20-30 parts pectin hydrolyzate, 20-30 parts herbal extracts, 10-15 parts modified dietary fiber, 8-12 parts trehalose, 5-10 parts natural antioxidants, 2-5 parts polyol, 1-3 parts metal chlorides, and 0.5-0.3 parts bovine serum albumin. The stabilizer is prepared by dissolving modified dietary fiber in deionized water and then incubating at room temperature for 4-6 hours. The modified dietary fiber is dissolved in deionized water at 40-60 degrees C for 20-30 minutes, followed by addition of herbal extracts, trehalose, polyols, metal chlorides. The mixture is then cooled to 25-35 degrees C, followed by adding bovine serum albumin and natural antioxidant under uniform stirring condition to obtain stabilizer.
