Benefits of technology

This patent is about creating plant-based electrolyte drinks that have low or no sugar and a high potassium to sodium ratio. The drinks have a clean and salty taste and can help re-hydrate the body, prevent dehydration, or treat potassium deficiency. These drinks can also be used as a base for making your own re-hydration or electrolyte replacement drink. The invention provides a useful or commercial choice for people who want to avoid excessive sugar consumption and ensure they are getting enough potassium to balance their electrolytes.

Problems solved by technology

Plain or natural water has a low mineral content and therefore does not adequately replace such minerals.
It is also limited in its thirst quenching ability and therefore can provide lower effectiveness in satiating water intake compared to other drink products.
These ‘chemical mixtures’ are mainly sodium salt based but for most of the population sodium salt intake already greatly exceeds dietary recommendations.
Consumption of the higher levels of sugars while re-hydrating can result in net energy intake above that lost in exercise.
The use of juices in re-hydrating can result in high energy intake and a contribution to weight gain due to their natural sugar content.
Acid fruit juices can exacerbate gastrointestinal conditions causing stomach upset or irritation to the mouth and throat.
The acidic nature can also contribute to erosion of the tooth enamel.

Preparation of a Sugarcane-Based Electrolyte Composition and its Concentrate

[0069]This example describes the preparation of a sugarcane-based electrolyte composition and its concentrate using sugarcane juice as starting material. A schematic of the process is shown in FIG. 1.

[0070]Table 1 below shows the typical composition of sugarcane juice based on solids (Watford S (1996) Composition of cane juice. Proceedings of the South African Sugar Technologists' Association 70, 265-266.)

Preparation of a Sugarcane-Based Electrolyte Concentrate

[0078]This example describes the preparation of a sugarcane-based electrolyte concentrate using clarified sugarcane juice as starting material.

[0079]Sugarcane electrolyte concentrate was produced from clarified sugarcane juice filtered through 100 micron stainless steel strainer from a sugar mill. The clarified juice of about 10.9% w / w total sugars was used in a two-step membrane process to produce sugarcane electrolyte concentrate (sugarcane plant sap concentrate).

[0080]A first step of the filtration was conducted using a nanofiltration (NF) membrane at an operating pressure of 35 bar and 40° C. temperature. About 375 kg of the juice was taken into a jacketed stainless steel tank and heated up to 40° C. The juice from the tank was pumped into a high pressure membrane filtration unit feed tank which is of about 20 kg capacity. The feed was frequently topped-up with fresh juice as the filtration continued while a portion of the ...

Preparation of an Apple Juice-Based Electrolyte Concentrate

[0084]This example describes the preparation of an apple juice-based electrolyte concentrate using apple juice concentrate as starting material.

[0085]A commercial apple juice concentrate of about 70 Brix was diluted with seven times RO water to obtain a single strength apple juice. This single strength juice with about 7.9% total sugars by weight was used as feed for apple electrolyte production.

[0086]A two-step membrane filtration process similar to the one described in Example 2 was used to produce apple electrolyte concentrate.

[0087]In step 1 apple juice feed was heated to 40° C. and filtered using a nanofiltration membrane. The NF permeate, unlike sugarcane juice permeate, was found to have around 4% total sugars. This is because the sugars present in the apple juice are mainly monosaccharides such as fructose and glucose (instead of sucrose as in sugarcane juice) and easily permeate through the NF membrane. In this case...

Abstract

This invention relates, inter alia, to various plant-based electrolyte compositions, methods of preparing them and methods of using them. One embodiment concerns a plant-based electrolyte composition comprising a plant-derived electrolyte content high in potassium relative to sodium, and a plant-derived carbohydrate content less than about 6% weight / volume. Another embodiment concerns a method for re-hydrating an individual or preventing dehydration or over-hydration of an individual or for preventing or treating potassium deficiency in an individual, by administering to the individual a plant-based electrolyte composition. The electrolyte compositions can be prepared from sugarcane juice, sugar beet juice, sweet sorghum juice, palm syrup, maple sap, vegetable juice or fruit juice.

Description

TECHNICAL FIELD[0001]This invention relates, inter alia, to plant-based electrolyte compositions and to methods of preparing them. In one embodiment the invention concerns natural electrolyte compositions prepared from sugarcane that have an electrolyte content high in potassium relative to sodium and a low carbohydrate content in comparison with most commercially available plant juice drink products.BACKGROUND ART[0002]Drink products are consumed to replace fluids and minerals (salts / electrolytes) lost in sweating and excretion. Plain or natural water has a low mineral content and therefore does not adequately replace such minerals. It is also limited in its thirst quenching ability and therefore can provide lower effectiveness in satiating water intake compared to other drink products.[0003]Electrolyte drink products are consumed to replace salts (minerals / electrolytes) lost due to sweating or gastrointestinal diarrhoea. The salts are essential for muscle and nerve functioning. Co...
