Method for operating a tunnel pasteuriser with a plurality of sequentially successive treatment zones, wherein containers with a product packed therein are transported by means of a conveying device through the treatment zones and in so doing are heated with treatment media having different actual media temperatures, are pasteurized and preferably then cooled again, wherein the actual media temperatures are detected by a control unit and compared with target media temperatures, and wherein heating and/or cooling devices are controlled based on the comparison, characterised in that during the treatment of the containers, initial values for an optimisation are formed from the actual media temperatures of the treatment zones, and the target media temperatures are determined by means of a prediction model for determining the expected degree of pasteurisation with the optimisation, such that at least a minimum degree of pasteurisation of the containers is achieved.

There is provided a soy whey-derived beverage comprising 12-30 mg/L free soy isoflavones. There is also provided a method for forming the soy whey-derived beverage comprising: providing soy whey; adding a microorganism to the soy whey; and fermenting the soy whey at a predetermined temperature and period of time. In various embodiments, the beverage has an alcohol content of <0.5% by volume or >0.5% by volume or a total isoflavone content of >20 mg/L. In a preferred embodiment, the microorganism is a yeast and/or the beverage is preferably wine.

An improved system and process for rapidly producing distilled spirits having characteristics associated with a much longer maturation process is provided. The method involves contacting wood with an unmatured distilled spirit under heated conditions and contacting the resulting heat-treated spirit with actinic light. The disclosure provides embodiments where a spirit is sequentially processed through heat and actinic light treatment. The disclosure also provides embodiments where a heat-treated spirit is mixed with a spirit that has been separately treated with light to give characteristics of a mature spirit. Air may also be percolated through a mature spirit in a container with a headspace at a gauge pressure between about 25 inHg and about 30 inHg, until the alcohol concentration of the mature spirit is reduced by between about 1% to about 2% by volume, and until the total volume of the mature spirit is reduced by about 10% or less.

An improved system and process for rapidly producing distilled spirits having characteristics associated with a much longer maturation process is provided. The method involves (a) subjecting an unmatured spirit to ultrasonic energy at a power of at least 3 Watts/Liter for at least one hour while maintaining the temperature of the unmatured spirit between 90 F. and 150 F.; and (b) subjecting the unmatured spirit and wood to actinic light at a wavelength ranging from 400 nm to 1000 nm for a cumulative exposure of at least 2,280,000 lux hours. The disclosure also provides embodiments where a spirit processed with ultrasonic energy is mixed with a spirit that has been separately treated with light to give characteristics of a mature spirit.

Time-reducing and flavor-enhancing techniques for alcoholic spirits may be provided as an alternative to conventional barrel-aging. Numerous controllable variables may be accessible for control at one process control panel or unit for a spirit-aging system. Variations in pressure, day/night cycle time, % O.sub.2, ratio of exposed wood surface to gallons of spirit, variations in spirit liquid temperature, and the amount of rough and ultrasonic mixing variables may be made to decrease the aging time. The aging process may be monitored for the changing spirit characteristics by drawing periodic samples to compare to spirit-quality target goals. Combinations of the variables may be optimized for these goals. Changes also may be made to the variables to address issues arising for quality control. All or most of the vapor naturally emitted by the spirit may be avoided or captured in a container or vessel with no or substantially reduced volume loss.
