DETAILED DESCRIPTION
(6) A detailed explanation of the composition of matter and process according to preferred embodiments of the present invention are described below.
(7) D ethyl 3-hydroxybutyrate, and D 1,3-butanediol have each been shown to be safe for human consumption. D ethyl 3-hydroxybutyrate, and D 1,3-butanediol can each be converted into β-hydroxybutyrate and can serve as a substrate for brain metabolism. In addition, D ethyl 3-hydroxybutyrate, and D 1,3-butanediol are hypoglycemic agents, meaning they can reduce glucose levels in the blood. Moreover, when used, e.g., as an alcohol in a beer, it can help initiate and/or maintain ketosis.
(8) Beers, like many ethanol-based beverages, contain carbohydrates. Imbibing beer and/or ethanol-based beverages can prevent the initiation of ketosis and can destroy ketosis. Enjoying such beverages can be difficult while trying to maintain or initiate ketosis. Those wishing to initiate and/or maintain ketosis, whether it be for wellbeing, weight loss, health, lifestyle, and/or other reasons, can enjoy beer and/or alcoholic beverages while facilitating ketosis by drinking beer and/or beverages that utilize D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol in place of, or in addition to, ethanol. Moreover, unlike ethanol, the use of D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol can reduce the glycemic effects of ingesting the carbohydrates of the beer or beverage.
(9) As used herein, the term “beverage” can relate to consumable liquids including but not limited to water, carbonated water, naturally and/or artificially flavored waters, soft drinks, teas, juices, extractions, alcohol-containing beverages, and other known consumable liquids. Beverages can also include fermented beverages such as but not limited to beers, ciders, wine, kombucha, spirits, hard soda, and other known consumable alcoholic beverages.
(10) Embodiments can include a ketogenic friendly beer for those that pick a ketogenic diet, which can entail maintaining ketone bodies in the blood at levels, for example, above 0.5 mmol/L by restricting calories or carbohydrate intake. Drinking beer that contains D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol can help maintain ketone body levels in the blood. Moreover, the D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol can help suppress glucose levels in the blood and counteract the taking onboard of carbohydrates from in the beer. For example, a person may maintain a ketone body level of about 2.5 mmol/L. Drinking ethanol-based beer can result in a significant drop in the person's ketone body level to, e.g., 0.2 mmol/L, the person can maintain and can even increase his or her ketone body level by drinking D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol beer. Depending on the ratio of D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol-to-carbohydrate, the person's ketone body level can be lowered, though less severely than from an ethanol beer, can be maintained, or can be increased.
(11) In one embodiment, a “keto” beer or beverage, can facilitate ketosis. It should be understood that, as used herein, keto beer can refer to any beverage in which the molecules and their precursors D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol are the primary alcohol ingredient. In some embodiments, any of the following including precursors, can be utilized: D beta hydroxybutyrate salts, D beta hydroxybutyrate, D 1,3-butanediol monoester, D ethyl hydroxybutyrate, hydroxybutyrate, D hydroxybutyric acid, and/or (R, R) Butanoic acid, 3-hydroxy-, 3-ethoxy-1-methyl-3-oxopropyl ester. Each The ratio of D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol to-total calorie of the beer can be chosen such as to facilitate a ketogenic diet by providing a neutral or better than neutral effect on ketone body levels in a drinker's blood. For those who are not in ketosis, for example a ketone level of 0.0 to 0.5 mmol/L, a keto beer can facilitate initiation of ketosis. In some embodiments, a keto beer can further reduce glucose levels that would otherwise be increased by the consumption of food, such as those in a meal.
(12) Utilization of D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol can have other benefits. Its use can provide a temporary ketogenic effect that can have benefits for weight loss and hunger suppression, as well as improvement in brain-function and increased physical performance. D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol can be utilized to create a beer or other alcoholic beverage that can be lower in carbohydrates than existing beers and/or cocktails, or it can be used to create beverages that have a net effect on how a body treats those carbohydrates. Due to the appetite suppression nature of ketone bodies, a ketogenic friendly beer can provide drinkers a full feeling and prevent them from over-drinking. Based at least in part on this effect, a keto beer can be safer than ethanol. Unlike traditional beer that lowers inhibitions and can lead to further unregulated drinking, a keto beer can provide a fuller and more content feeling at a lower quantity consumed than with ethanol and can help reduce the desire to drink more and become intoxicated. The beverage may be useful for recovering alcoholics.
(13) Some of those who imbibe alcoholic drinks can on occasion suffer from so-called hangovers. Keto beer may reduce the severity or even eliminate hangovers and side effects common from ethanol based beer and drink products.
(14) A keto beer or wine can be made utilizing one or more of several steps. For example, in an embodiment, a beer can be made by providing mash, boiling the wort, adding hops, and then fermenting the wort into a beer, as known in the brewing arts. In the case of wine, grapes can be crushed and allowed to ferment. Ethanol from the fermentation can be extracted and replaced with D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol. Extraction can be performed by boiling off the ethanol, which has a low boiling point of about 173° F. at sea level. Extraction can also be performed by fractional, or freeze, distillation, vacuum distillation, reverse-osmosis, or other methods for producing dealcoholized the beer. The beer can be considered dealcoholized, or nonalcoholic, when the ethanol content is less than 0.5 percent alcohol by volume. The substitution step can include providing the same, more, or less D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol than the amount of extracted ethanol. To improve flavor, several steps can be performed before or after alcohol substitution, such as dry-hopping, flavor-masking agents, and/or flavoring agents.
(15) Keto beer can be carbonated by injecting CO2. Carbonation from CO2 injection, while common and often acceptable, can cause metallic or sour flavors in some beverages. To further improve the taste of the beer, carbonation can be performed alternatively through a second fermentation. The beer can be carbonated with the addition of sugar and starter yeast. Very little ethanol is produced in the first 24-72 hours of this second fermentation but CO2 can be produced. The yeast can be specifically chosen from cultures known to produce little alcohol or that are alcohol intolerant.
(16) In an embodiment, a keto beer can be brewed as described above. However, before the fermentation process achieves 0.5 percent alcohol by volume (ABV), fermentation can be halted. D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol can be added to the beer to achieve a desired ABV percentage.
(17) In an embodiment, the beverage is provided with an additive including preservatives, color additives, flavors and spices, flavor enhancers, emulsifiers, and stabilizers.
(18) D Ethyl 3-hydroxybutyrate and/or D 1,3-butanediol can also be advantageously utilized as spirits. For example, substantially pure D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol, or a high-content solution, can be utilized for mixing cocktails. The high-content solution can include D ethyl 3-hydroxybutyrate and/or D 1,3-butanediol and water. The solution can be aged with wood and/or include flavor additives. A benefit of such cocktails is that they can provide pleasant intoxicating effects while also providing health benefits of a ketogenic diet, for example by counteracting the carbohydrates present in most cocktail recipes and by maintaining ketosis. Such alcoholic beverages can assist in weight loss, either directly or from appetite suppression.
(19) In an embodiment, the beverage is provided with an adjunct including solid and liquid adjuncts commonly used in the brewing arts.
(20) In an embodiment, the beverage is provided with an additive including preservatives, color additives, flavors and spices, flavor enhancers, emulsifiers, and stabilizers.
(21) In an embodiment, the beverage is provided as a low carbohydrate and even a zero carbohydrate beverage. In one example, a low carbohydrate beverage can include beverages having a carbohydrate total of less than 10 g per serving. All natural low calorie sweeteners such as Xylitol, Erythritol, monk fruit, and/or stevia and artificial sweeteners such as sucrose, sucralose, acesulfame potassium, aspartame, saccharin can be utilized at a suitable concentration typical in beverage formulation. The beverage can be formulated as a low calorie beverage, such as a beverage having less than 100 calories per serving.
(22) The term “additive”, as used herein can include D ethyl 3-hydroxybutyrate, D 1,3-butanediol, D beta hydroxybutyrate salts, D beta hydroxybutyrate, D 1,3-butanediol monoester, D ethyl hydroxybutyrate, hydroxybutyrate (3-hydroxy-, 3-ethoxy-1-methyl-3-oxopropyl ester), D hydroxybutyric acid, and (R, R) Butanoic acid, 3-hydroxy-, 3-ethoxy-1-methyl-3-oxopropyl ester. The one or more additives can be added in combination to provide a desirable and palatable flavor profile to the beverage while avoiding potential astringent or unpalatable flavors if provided individually. Further, it is known that pH balance and excessive salt intake are a result of over-ingestion of certain therapeutic compounds. Mixing the molecules listed herein may promote a healthy pH balance and salt intake post-ingestion.
(23) When provided as an additive to a beverage, additive may, whether individually or in combination, provides an intoxicating effect to the consumer without the unfavorable side-effects of ethanol intoxication. Further, each molecule has been shown to promote, induce, sustain, and/or regulate ketosis which has been shown to have a number of desirable benefits.
(24) Flavoring agents can include, natural flavoring substances, nature-identical flavoring substances, artificial flavoring substances, diacetyl, acetylpropionyl, acetoin, isoamyl acetate, benzaldehyde, cinnamaldehyde, ethyl propionate, methyl anthranilate, limonene, ethyl decadienoate, allyl hexanoate, ethyl maltol, ethylvannillin, methyl salicylate, manzate, glutamic acid, glycine salts, guanylic acid, inosinic acid, acetic acid, malic acid, citric acid, ascorbic acid, fumaric acid, and lactic acid. Coloring agents can be added to provide a favorable color to the beverage mixture.
(25) In some embodiments, the beverage is provided in a single-serving container for consumer use. Alternatively, the beverage is provided in a multi-serving container such as a keg.
(26) As one skilled in the art will appreciate, embodiments of the present invention may be embodied as, among other things, a composition of matter and a method for making compositions of matter. Other embodiments are within the scope of the following claims.
