Embodiment Construction

[0081] The present invention is discussed with reference to the accompanying process flow diagram, which encompasses one embodiment of the invention.

[0082] according to figure 1 , harvested herbs, especially lemon balm, as shown in reference number 1. According to a preferred embodiment, the herbs are screened to remove unwanted parts such as sand and stones. The herb 50 thus obtained is dried in unit 2 by a dryer, such as a belt dryer. Then, in unit 3, the dried herb 51 is extracted with water at room temperature, ie the first extraction step. Aqueous extract 52 is acidified in unit 4, for example, by adding phosphoric acid to a pH between about 1.7 and 3.5, to form acidified plant extract 53. In unit 5, the acidified plant extract 53 is filtered and the filtrate 54 thus obtained is sent to extraction unit 6 for an extraction step with an organic solvent, for example n-butanol. In unit 7, the organic phase 55 from this organic solvent extraction step is evaporated unde...

Abstract

The present invention relates to a method for the preparation of a water-soluble extract based on a vegetable biomass of the Melissa officinalis family, which extract is used as a sulphite substitutein the aforesaid winemaking process, which method comprises one or more of the following steps: a) harvesting the herb, b) drying the herb obtained in step a), c) extracting the dried herb obtained instep b), wherein the aforesaid extraction step c) comprises at least two sub steps, a first sub step comprising a first extraction step with water, wherein the aqueous phase thus obtained functions as the starting material for the second sub step comprising an extraction step with an organic solvent, wherein the aqueous phase is acidified before the second extraction step.

Description

technical field [0001] The present invention relates to a process for the preparation of water-soluble extracts of plant biomass, and also to a process for the preparation of low-alcohol beverages, in particular wine, from grapes which undergo a series of processing steps including, inter alia, pretreatment, Especially crushing and crushing, with possible removal of the stems, fermentation, aging and final bottling, possibly with a brief filtration. The present invention also relates to the application of the herbal plant extract. Background technique [0002] The winemaking process of preparing wine from grapes is a very old process, and the grapes used in this process can be removed from the grape stems. The grapes are crushed in a press and the resulting substance, called must, is pumped into fermentation vessels. In the traditional process, sulfites must be added to prevent oxidation of the must. Subsequently, the first fermentation process takes place, during which s...
