Abstract
An apparatus for treating food must, such as grape must, may include a food must chamber configured to apply an electric pulse to the food must in a manner that causes an electric field to be generated within the food must. A pulse generator may be configured to deliver an electric pulse to the chamber that has a pulse width of between 10 and 100 nanoseconds. The chamber and the pulse generator may be configured such that they cause the electric field that is generated within the food must to be at least 1 kV/cm.
Claims20
A method of making wine comprising:
- crushing grapes in a crusher to make grape must;
- subjecting the grape must to an electric field that is created by one or more electrical pulses that each have a width of between 10 and 100 nanoseconds;
- and
- pressing the crushed grape must that has been subjected to the electric field in a press, thereby producing wine.
A method of making wine comprising:
- crushing grapes in a crusher to make grape must;
- subjecting the grape must to an electric field that transfers no more than 10 Joules to each gram of must;
- and
- pressing the crushed grape must that has been subjected to the electric field in a press, thereby producing wine.
