TECHNOLOGY FOCUS - FOOD - Preferred Method: The drinks are produced by fermenting the filtered feed liquid containing multiple sugars, where the drink production involves using lime milk for neutralizing, where sulfuric acid in the feed liquid is reacted to produce calcium sulfate which is deposited in the bottom portion of a storage cylinder; performing a separation process to remove gypsum; obtaining a neutral clarified feed liquid; adjusting sweetness of the feed liquid to 20-30 degrees Be; adding cane sugar to adjust sweetness if the required sweetness is not reached; adjusting pH to 6.2-6.8; heating feed liquid to 90-95 degrees C for 10-20 minutes; sterilizing and natural cooling to 30-35 degrees C; inoculating Taiwan No. 396 yeast and Lactobacillus delbruckii, such number of microorganisms is 1x 105-5x 106/ml of feed liquid after inoculation; performing fermentation at 25-40 degrees C for 20-35 hours, stopping the fermentation when pH value is 4-5 and ethanol content is 0.5%; and performing quality analysis of the drink to confirm presence of no harmful substance, where the obtained drink can be drunk directly, and salt and cane sugar can be added according to taste requirement. The drink is packaged in bottles or jars by sterile method, where the drink is sterilized for 10 minutes at 115 degrees C, cooled, packaged and stored in warehouse.    TECHNOLOGY FOCUS - PHARMACEUTICALS - Preferred Method: The method preferably involves (a) crushing and grinding root and stem of yellow ginger, sieving through mesh size of 20-30 meshes, adding the sieved material into a stirring type hydrolyzation cylinder such that ratio of material and water is 1:4-35, then adding alpha -amylase (dosage of amylase is determined by enzyme activity), controlling the dosage of amylase to be 5-8 unit/g powder material, stirring the feed liquid uniformly, adjusting pH to be 5-5.7, and adding 0.15% of calcium chloride as a protection agent and activator, (b) steaming and boiling above-cited materials at normal pressure and heating to 95-97 degrees C, maintaining at the temperature for 60 minutes, adding alpha -amylase and pasting starch, (c) adding 98% of sulfuric acid using 3% of water from a feeding hole of the stirring type hydrolyzation cylinder, starting a mixer to stir uniformly, pressurizing to 0.23-0.485 MPa and heating to 120-150 degrees C (temperature higher than boiling point of menstruum) to inactivate alpha -amylase completely, and (d) acid-hydrolyzing for about 1 hour, opening a liquid outlet hole at the bottom of the hydrolyzation cylinder to make acid hydrolyzed feed liquid flow out from the valve at the bottom of the hydrolyzation cylinder, flowing the liquid through a filter to obtain filtered residue, neutralizing and washing filtered residue by lime milk, merging the liquids obtained from the first and second washings into filtrate that has to be treated, feeding the neutralizing and washing liquid into a circulation washing liquid pool and reusing it again, baking and crushing the neutralized filtered residue, heating and back flowing for 3-4 hours by 70-95% of ethanol, separating hot ethanol out, then adding ethanol again, repeating the operation for 3-4 times, dissolving saponin in the hot ethanol, extracting tigogenin by the merged extracting solution, drying the separated filtered residue and producing fuel products using the residue.
