Abstract: A method for making a sustained energy beverage comprises mixing together inulin, fruit juices and/or concentrates, and complex carbohydrates from grain dextrins and fruit juice. In a batch method, the mixture is pasteurized, cooled and then stored for use later. A finished beverage is completed by mixing in acids and buffers, and blending. A concentrate is produced that can be sold wholesale, or it can be diluted to 6-22 brix with water. In both the continuous and batch methods, it is pasteurized just before or during bottling to produce a retail sustained energy drink.

Abstract: A pasteurization alternative comprises starting with a fruit pomace (pulp). For example, blackcurrant pomace usually starts at about 50% water. It can either be dried first or treated directly with alcohol. If direct, the undried pomace is treated with ethanol or propanol such that there is a minimum of 20% alcohol in the volatile phase. If dried first, the pomace is dried in an air, vacuum, or freeze dryer, keeping temperatures under 45° C. (113° F.). The alcohol is then sprayed over the dried pomace, such that all surfaces will be coated with it. After 1-5 minutes contact time, the alcohol is evaporated off under vacuum and recovered for the next batch.
