DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0042] The present invention relates to novel stabilization of liquid pharmaceutical and nutritional supplements.

[0043] Although the examples provided herein are nutritional supplements, it is contemplated that any Active Pharmaceutical Ingredient (API) or nutritional supplement ingredient is formulated according to the invention disclosed herein and will produce a stable composition with desired shelf life.

[0044] In one embodiment, the present invention includes the process of blending an herbal pre-mix with a small amount of the base (in this case, agave or honey) and heating at a high temperature (about 180-200 degrees Fahrenheit), subsequently mixing the pre-mix with the remainder of the formula, which has been heated to be at a lower temperature (about 100.degree. F.). By heating the pre-mix and base and the remainder of base separately and at different temperatures, the novel process will reduce the froth and prevent flavor changes. This is the first time such a system has been used.

[0045] In one embodiment, the present invention includes using approximately 80-90% solid base (in this case, 84% solid agave or honey depending) with combination of cultured dextrose and citric acid in order to not have to put in a non-organic, synthetic preservative systems. This allows the present invention to have a certified organic base without any synthetic preservative systems. This is the first time this combination of high percentage solid base, citric acid and cultured dextrose has been used.

[0046] In formulations practice, it is known that often two or more preservatives are provided. Sometimes they are provided for specific preserving characteristics. However, there are preservative systems that are utilized with various components having beneficial synergistic affects even thought the exact mechanism of the beneficial synergistic affects is not clearly understood. This is true in the present formulation whereby a synergistic system has been discovered, demonstrated effective, yet is operating in a mechanism not fully understood.

[0047] In the present invention, particular ratios have been discovered whereby a plurality of components in the ratios herein, provide the desired effect.

[0048] Initial formulas were exactly the same, except the agave was around 60-70% solid and they did not have cultured dextrose. These formulas did not have an effective preservation system, and failed stability testing.

Manufacture

[0049] In one embodiment, the present invention is performed using the following steps:

[0050] Providing organic herbal extracts and combing them into an herbal pre-mix, blend into a small amount of the base (here, agave or honey depending) and heat between 180-200 degrees Fahrenheit, to create the pre-mix containing the herbal ingredients.

[0051] Although the examples demonstrate Agave and Honey as the base, the term "base" as used herein includes components having similar viscosities and characteristics including, but not limited to tapioca syrups, fruit syrups, maple syrups, elderberry syrup, combinations of bases, and the like.

[0052] As is known, Agave will break down at 320.degree. F. and will even begin to change at 210.degree. F., therefore 180-200.degree. F. is one ideal temperature range to extract the herbal ingredients into the agave/honey without hurting them or the agave/honey. The present invention contemplates temperature for other types of syrups with similar consistencies at similar temperatures.

[0053] Combining the pre-mix and mix with the remainder of the agave/honey (the majority of the formula), which was heated to about 100.degree. F. degrees until the pre-mix is homogenous and becomes one product.

[0054] Cooling the combined mixture to room temperature and introduce flavors once at room temperature.

[0055] Placing the combined cooled room temperature product containing flavors (pre-mix and remainder of formula) and mix into a mixer.

[0056] It has been discovered that separately handling the pre-mix and remainder of formula separately, prevents flavor changes and froth. This then helps reduce and prevent sheer and flavor changes as the sheer and flavor changes are caused by warming at a high temperature. Heating the herbal pre-mix is necessary to blend the herbal ingredients into the base.
