A method for industrially producing mogroside, fructus momordicae sugar/wine and mannitol from fresh fructus momordicae comprising the following steps:
- S1, freshness-preserving and post-ripening:
- (S1-1) fruit sorting and storing:
- sorting out and removing old and green fruits and poor-quality fruits from harvested fresh fructus momordicae, and storing the sorted fructus momordicae in a warehouse;
- (S1-2) freshness-preserving:
- standing the fructus momordicae in the warehouse for 60-240 days and intervally spraying a mixed aqueous solution of ε-polylysine hydrochloride and calcium propionate, while intervally activating an ozone cycle, with storage conditions for freshness-preserving being a temperature of 2-6° C., and a daily relative humidity of 80-90% but 55-65% maintained within 12 hours after each spraying of a chemical agent;
- and
- (S1-3) saccharifying and post-ripening:
- raising a temperature to 22-26° C. at a heating rate of 0.15-0.35° C./h in the warehouse, maintaining the relative humidity of 80-90% during the heating process, and a relative humidity of 70-80% when reaching the target temperature, changing air every 22-26 hours to maintain normal oxygen concentration, absorbing carbon dioxide to adjust the concentration of carbon dioxide with an alkaline solution, spraying an aqueous solution of ethephon evenly every 4-6 days, and keeping a post-ripening process for 15-30 days;
- S2, preparation of mogroside:
- (S2-1) water extracting:
- crushing the saccharified and post-ripened fresh fructus momordicae and extracting same with water to obtain an extract;
- (S2-2) subjecting the extract to ceramic membrane microfiltration;
- (S2-3) gradient processing with combined resins:
- subjecting a ceramic membrane clear solution to adsorption and desorption of the following resins sequentially:
- a first macroporous adsorption resin column, an anion exchange resin, and a second macroporous adsorption resin;
- and then performing desorption to obtain a combined resin refined solution;
- (S2-4) concentrating the combined resin refined solution to a concentration of 17-25 Baume degree to obtain a concentrated solution;
- and
- (S2-5) spray-drying the concentrated solution to obtain mogroside;
- S3. preparation of fructus momordicae sugar:
- (S3-1) taking an appropriate amount of the mogroside from step (S2) and dissolving same by adding purified water as an adhesive;
- and
- (S3-2) charging any one or a composition at any ratio of four non-sugar sweet substances of erythritol, arabinose, allulose, and mannitol into a boiling granulator step by step, spraying the adhesive evenly for boiling granulation, and drying same to obtain the fructus momordicae sugar;
- S4. preparation of fructus momordicae wine:
- (S4-1) liquid fermentation of first macroporous adsorption resin effluent:
- collecting a first macroporous adsorption resin feed effluent in step (S2-3), combining same with a water-washing solution, and concentrating same to 5-25 Brix, adding a complex enzyme preparation, and fermenting same until a strong wine aroma appears to obtain a fermentation liquor;
- (S4-2) distilling the fermentation liquor, collecting a distillation bottom liquor and a distillate separately;
- and
- (S4-3) adding the mogroside obtained in step (S2) to the distillate to obtain the fructus momordicae wine;
- and
- S5. preparation of mannitol:
- (S5-1) taking the distillation bottom liquor from step S4, microfiltrating same through a complete set of ceramic membrane equipment, and collecting a filtrate to obtain a ceramic membrane clear solution;
- (S5-2) subjecting the ceramic membrane clear solution to nanofiltration for decolorization to obtain a discolored solution;
- and
- (S5-3) concentrating the discolored solution and adding ethanol while hot, and cooling same for crystallization to obtain mannitol.
