Field of the invention

The present invention relates to drinks, methods and formulations for preparing stable alkaline drinks.

Background of invention

Drinks are liquids which are intended for human consumption. This includes 2 main categories ^' , alcoholic and non-alcoholic drinks. Alcoholic drinks are drinks that contain an amount of ethanol above a certain level specified by the legal authorities. For example, in the United Kingdom, drinks are considered alcoholic if contained ethanol amount above 0.5% by volume, such as beers, wines, ciders, spirits and others.

Non-alcoholic drinks, on the other hand, are drinks that contain no ethanol. Some legal authorities allow an ethanol threshold level in non-alcoholic drinks. For instance, in the European Union, drinks that contain less than 0.5% of ethanol by volume are still considered non-alcoholic drinks. Non-alcoholic drinks include a wide variety of drink categories, including but not limited to, water, flavoured waters, milk, hot drinks (e.g. tea, coffee, etc), soft drinks, fruit juices and others. Such drinks comprise various ingredients and are produced by numerous processes including water purification, blending methods, hot fill, cold fill, pasteurization, infusion, juicing, carbonation and others.

Alkaline drinks are a non-alcoholic category of drinks that currently compose, mainly, of premium alkaline water production with a global market share estimated at 521 million litres in 2017 and with a projection of 2.3 billion litres by 2023. Alkaline water is a premium water that has a pH level above 7. Research reports suggest that the consumption of alkaline water provides specific health benefits, including effective hydration, enhancement of rehydration after exercise, aid the digestive system in ailments such as constipation and diarrhoea, replacement of lost minerals during physical activities and exercise and increased oxygen levels in blood and others.

However, the possibility of producing alkaline drinks, other than just premium plain alkaline water, is currently hindered by the failure of the current methods of alkaline water production to hold the alkaline pH following the addition of drinks flavouring agents, colouring agents, solubilizers, surfactants, stabilizers, vitamins, oil ingredients, sugars, food grade materials, pharmaceutical grade materials, sweeteners and/or any other essential chemical or non-chemical elements that constitute the overall build-up of a stable, potable and palatable drink with an alkaline pH.

Currently, alkaline water can be categorised into two categories according to production methods: naturally high pH water and artificially enhanced water. Naturally high pH water is sourced from a natural spring or aquifer. It has a naturally high pH level and contains natural minerals. On the other hand, artificially enhanced water is sourced from natural or municipal sources and is then subjected to a form of artificial treatment or processing to increase its mineral content or its pH level. Among the processing methods commonly used for production of artificially enhanced alkaline water are water electrolysis and chemicals addition.

However, these abovementioned processes suffer from a number of limitations and disadvantages including running costs, exhaustion of valuable natural resources, the use of electricity, production of waste water (mainly aggressive hazardous acidic water) as by-prodcuts, unsustainable use of chemicals and the chemical and physical properties of the end product particularly the instability of pH levels of the produced water which is a key obstacle for formulating and producing stable, potable and palatable alkaline drinks.

Recently, it was reported the development of a disruptive technology that enables the production of stable alkaline water with pH levels up to 10.5 or more. This technology was developed by WET HOLDINGS (GLOBAL) LIMITED (Patent numbers: PCT/GB2016/000033, PCT/GB2019/000084 and GB1906865.9) which utilises a system, termed Activated Enhancement System (AES), that effectively monitors and controls a non-magnetic suspended agitation process (n-MSAP) that can produce stable alkaline water at commercial volumes without the need for electrolysis, synthetic chemicals or the use of naturally alkaline water source. Here, in this invention, we report a range of stable alkaline drink formulations that can hold the addition of drink ingredients, including but not limited to, flavouring agents, colouring agents, stabilizers, surfactants, solubilizers, sugars, sweeteners, preservatives, buffers, oil ingredients, antioxidants and other chemical ingredients.

Statements of the invention:

The present invention provides drink methods and formulations for the production of bottled or packaged or canned stable alkaline drinks in which the pH of the drinks remains alkaline after the addition of various drink ingredients and the application of various standard blending, filling, bottling and packaging processes including, but not limited to, pasteurisation, filtration, nitrogen fill and others.

This invention provides drink formulations comprising alkaline water produced at commercial volumes by non-magnetic suspended agitation process (n-MSAP) by using the Activated Enhancement System (AES) which provides stable alkaline water with pH ranging from 8-10.5 or more, which are described in our patent applications Nos. PCT/GB2016/000033, PCT/GB2019/000084 and GB1906865.9.

In accordance with the details of the invention described in the abovementioned patents, the stable alkaline water produced by the n-MSAP via the AES is caused to flow directly into the bottling/packaging plant where it is caused to mix and blend with various drink ingredients to formulate the embodiments of drink formulations present in this invention. Alternatively, the stable alkaline water is caused to flow into a holding tanks which is then pumped to bottling and packaging plant for mixing and blending to formulate the embodiments of drinks present in this invention. The embodiments of drinks formulations can be bottled or packaged or canned by using various bottling or packaging or canning processes including, but not limited to, PET bottling, glass bottling, stainless steel bottling, cans, and others. The pH of the embodiments of drink formulations in this present invention remain alkaline after bottling or packaging or canning for extended periods of time. Furthermore, the TDS of the said drink embodiments may be 150ppm or below.

The embodiments of drink formulations in the present invention include, but not limited to, alkaline flavoured drinks, multi-vitamin alkaline drinks, alkaline sports drinks, alkaline infusion drinks, alkaline tea drinks, alkaline CBD drinks, alkaline protein drinks, alkaline soft drinks, alkaline functional drinks and others. In accordance with the details described in this invention, the embodiments of drink formulations may contain no sugar or reduced added sugar. Also, the embodiments of drink formulations may contain no artificial sweeteners.
