Alcohol-free beer is increasingly marketed with the claim “isotonic”. According to the European Food Safety Authority (EFSA), isotonic beverages should have an osmolality in a range of 270–330 mOsmol/kg. A method to determine osmolality in beer using an automatic cryoscope was applied and validated in this study. Isotonic and hypotonic beers can be...

... Another aspect of the balance between sugar and alcohol is the isotonicity of the beverages. Although alcohol-containing beers generally are in the hypertonic osmolality range, many alcohol-free beers fall into the preferable isotonic range, making the products interesting, for example, to restore the strength of people who perform strong physical exercise [38]. ...

Reducing the alcoholic strength in beverages as a strategy to reduce harmful alcohol use has been proposed by multilateral institutions such as the World Health Organization and governments worldwide. Different industrial and artisanal techniques are used to achieve low-alcohol content beverages. Therefore, regulations regarding the content of alcohol in beverages and strategies to monitor compliance are important, because they are the main reason for classification of the beverages and are central to their categorization and market labelling. Furthermore, analytical techniques with adequate sensitivity as low as 0.04% vol are necessary to determine the alcohol ranges necessary for classification. In this narrative review, the definitions of no and low (NoLo) alcohol products are described and the differences in the legal definitions of these products in several regions of the world are highlighted. Currently, there is clearly confusion regarding the terminology of “no”, “free”, “zero”, “low”, “light”, or “reduced” alcohol products. There is an urgent need for global harmonization (e.g., at the Codex Alimentarius level) of the definitions from a commercial perspective and also to have common nomenclature for science and for consumer information.
... The sodium content was quantified using an atomic absorption spectrophotometer with flame atomization (Micronal brand; Model B 262).

The objective of this study was to apply for the first time sugary kefir to produce a new isotonic with low sodium. Additionally, the microbial community profile of grains and fermented kefir was evaluated through metataxonomics. The kefir grains were inoculated into filtered water containing 40 g L-1 sugar at 25 °C for 48h. Grains and beverage samples were collected at 0, 24, and 48h for DNA extraction. The grains were separated, and the beverage was used to prepare the isotonic. The isotonic consisted of kefir (85% v/v), pasteurized juice (15% v/v), sodium citrate (0.2 g L-1), sodium chloride (0.427 g L-1), maltodextrin (22 g L-1) and citric acid (0.7 g L-1). The physicochemical and microbiological parameters were performed on days 0, 7, 15, and 30. All isotonic obtained presented sodium content below the commercial control. The presence of lactic acid bacteria and yeasts in all periods evaluated demonstrated the viability of isotonic kefir. Through metataxonomy, the genus Ethanoligenens was described as dominant for the first time in sugary kefir. Furthermore, the microbial diversity in the beverage was higher than that observed in the grains. This study provided a new low sodium isotonic based on sugary kefir for the first time.

Beer is a popular and the most preferred alcoholic beverage among consumers around the world. In Poland its annual consumption amounts to nearly 100 litres per capita, thus our country is among the world leaders in this field. The perception of beer has been significantly reoriented over the last twenty years. The beer revolution and the related changes in the brewing industry contributed this beverage to achieve a status of prestigious drink. The market of innovative craft beers develops very dynamically for they are, in terms of flavour and quality, an interesting diversified alternative to mass brands. Among them "beer specials" dominate. This term is usually used to describe all the top and bottom fermentation beers other than traditional lagers and pils. A trend of premiumisation has emerged; the expectations of consumers continue to grow regarding the quality of beer, its composition, sensory properties and health-promoting potential. On the market there are more and more offers of beers containing bioactive additives, minerals or gluten-free. In this paper there was characterised the current situation on the Polish beer market, including its over-all structure and that of the speciality and functional beers. In details were discussed raw material and technological aspects of producing functional beers, such as: non-and low-alcoholic, gluten-free, isotonic, probiotic, xanthohumol-fortified beers and also gruit beers containing herbal additives. According to the literature data analysis, the segment of functional beers clearly stands out and the interest in beers for special nutritional uses continues to grow. Low-and non-alcoholic beers are and presumably will be the fastest growing category on the market. © 2021, Polskie Towarzystwo Technologow Zywnosci Wydawnictwo Naukowe PTTZ. All rights reserved.

Background: Hypertonic and hypotonic conditions in pharmaceutical preparations decrease the drug's absorption and bioavailability. In addition, it can cause tissue damage. There are several calculation methods to regulate hypotonic preparations. However, there are no methods that can be used to regulate hypertonic preparations without causing dose-dividing problem. Objective: This study aimed to develop a new calculation using basic principle of freezing point depression method (cryoscopic) that can solve hypotonic and hypertonic problems, especially for hypertonic preparations through reducing the levels of additional ingredients. Methods: The calculation of Kahar method was successfully obtained by substitution and simplification in the basic principle equation of cryoscopic method, and then evaluated by resolving the problems in 42 sterile formula preparations and compared with White-Vincent method, cryoscopic method, equivalent NaCl method, and milliequivalent method through the analysis of its similarity and reliability. Results: The results of similarity analysis between Kahar method and other methods showed good similarity values with more than 0.880. Kahar method and cryoscopic method have the highest similarity of the calculation result with a similarity value of 1. The reliability analysis obtained very good result with Cronbach α = 0.990. Conclusions: These results suggest that Kahar method provides reliable equation with complete and efficient solution to hypotonic and hypertonic problems.

Alcohol‐free beer with isotonic properties is getting more popular and its production can be carried out by different production strategies; however, interrupted fermentation is still a challenge. Therefore, the objective of this study was to develop a low‐alcohol isotonic beer (<0.5% v/v) by interrupted fermentation. Moreover, the major objective is to compare the developed product to commercial beverages (sports drinks, ‘Pilsen' regular beer, alcohol‐free beers and low‐alcohol isotonic beer). The beverages were evaluated based on pH, alcohol content (% v/v), total titratable acidity (mEq L⁻¹), osmolality (mOsmol kg⁻¹), bitterness International Bitterness Units, colour European Brewery Convention, total phenolic compounds (mg L⁻¹ gallic acid), reducing and total sugars (%) and Na and K contents (mg L⁻¹). The developed low‐alcohol isotonic beer presented characteristics similar to sports drinks, with the advantage of being richer in phenolic compounds and suitable osmolality. Despite salts were added in its formulation, the grades attributed to all beers employed in the sensory evaluation, as well as the purchase intention did not present significant differences.
... These minerals and other compounds in AFB can help to recover after physical exercises [18], to reduce inflammation, and to reduce the chance of getting respiratory illnesses after intensive physical exertion, respectively [19,20]. Indeed, sportsmen seem to appreciate the properties of AFB which is reflected by an increased consumption of sports drinks and AFB over the past years [21,22]. The minerals in beer and AFB derive mainly from barley (75 %) and water (25 %), thus the mineral content of beer depends on the origin of the raw materials [17]. ...

The aim of the study was to obtain honey powders enriched with plant extracts by spray drying method and to implement them in the production of dry concentrate of isotonic drinks. Multifloral honey and maltodextrin dissolved in plant (mint, nettle and beetroot) aqueous infusions were transformed into honey powders using spray dryer. Obtained powders were examined regarding antioxidant activity (DPPH and FRAP), phenolics compounds and mineral composition (ICP-OES). The same drying method was used for dry concentrates of isotonic drinks production. For this purpose homemade isotonic drinks prepared according to various recipes using honey and other natural components (plant infusions and/or fruit juices and salt) were subjected for drying. Aqueous solutions (9% w/w) of obtained concentrated powders were examined in terms of osmolality, caloric value, reducing sugars content, mineral composition (ICP-OES) and antioxidant activity (DPPH, FRAP and phenolic compounds). Using plant infusions as solvents, enriched honey powders in antioxidants (4–10 times) and minerals (especially K, Ca, Mg) as compared to control samples. Produced dry concentrates of natural isotonic drinks after re-dissolving in water gave beverages characterized by proper osmolality, caloric value and strongly enhanced antioxidant properties as compared to commercial counterparts.
