The most popular types of cold drinks are water and soft drinks, which contain a sweetener and natural or artificial flavoring. The sweetener may be sugar, high-fructose corn syrup, fruit juice, or a combination of sugars. Other ingredients in soft drinks may include caffeine, coloring, and preservatives. If you’re looking for a healthier alternative, try water with natural flavors instead. Soft drinks may contain sugar substitutes such as stevia or honey.
Pasteurization
Consumers today expect food and beverage manufacturers to be truthful when they say the product has been pasteurized. This article explores the scientific knowledge regarding the safety of cold drinks. It describes the various components that make up soft drinks and discusses the lesser-known risks of chemical and microbiological contamination. Ultimately, consumers should be able to make an informed decision when purchasing products. In addition to pasteurization, there are other food safety considerations.
The most common reason for pasteurizing beer is to reduce microbial and enzymatic activity. It also increases shelf-life. This process involves the application of low temperatures for relatively short periods of time. It also preserves the beverage’s organoleptic and nutritional values. The cold-processed beverage then returns to ambient temperature, where it can maintain its quality. This process is a valuable step in the food-safety process of many products.
Microbiological spoilage
There are various microorganisms that can cause the spoilage of cold drinks. Bacteria and yeasts are the primary culprits. Wine and beer can be affected by spoilage-causing yeasts, bacteria, and pathogenic organisms. The fermentation process eliminates mold and other organic material that can lead to spoilage. Microorganisms that can affect soft drinks include acidophilic heat-resistant bacteria and yeasts. Water is susceptible to spoilage due to traces of maltose and other organic compounds.
Fungi are the second-leading cause of soft drink spoilage. Fungal contamination is often caused by the use of improper hygiene practices. In addition to food-grade materials, contaminated packages can lead to the growth of fungi. The basic conditions for fungal spoilage of soft drinks are high acidity and water availability. The pH value depends on various factors, including the activity of water, temperature, and the acid used. Lower pH values promote the growth of fungi.
DMDC
The DMDC cold drink ingredient is classified as a processing aid. It undergoes rapid hydrolysis, releasing naturally present carbon dioxide and methanol. Its addition to beverages has no effect on the final taste. The DMDC chemical name is dimethyl dicarbonate, which is also known as pyrocarbonate. This liquid is colorless and has a mild, pungent odor. It boils at 82 degrees Celsius, but solidifies at temperatures below 17 degrees C.
DMDC has a long history of use as a cold-sterilant in non-alcoholic drinks. It is added to beverages immediately before filling, and is highly effective against typical microorganisms that spoil beverages. Since 2010 and 2012, DMDC has been approved by the European Commission for use in pear and apple ciders. This approval stems from regulatory efforts to regulate the additive. It is also used to prevent microbial contamination in foods.
Health effects
It is common knowledge that drinking cold drinks has negative health effects, but do you really know why? Cold drinks, like coffee, tea, and even cold water, weaken the immune system and increase the risk of many illnesses. Also, they can affect digestion and cause sinus problems. For these reasons, it is important to understand the possible side effects of cold drinks. Here are some of them:
One study conducted at the National Yang-Ming University School of Medicine in Taiwan found that drinking 250 mL of ice water after a meal decreased heart rates by as much as five beats per minute. Another study conducted at the University of Fribourg, Switzerland, concluded that drinking cold water decreased heart rate by 2.9% in 90 minutes and reduced the workload on the heart. This result suggests that the health benefits of cold drinks are not as great as many claim.
Recipes
If you’re craving something cold and refreshing, then you’re in luck. Fabulessly Frugal has some great recipes for cold drinks. Here’s a list of her top picks:
Iced coffee is a classic. Served chilled, it’s made with two oz. of coffee concentrate, two teaspoons of Luxardo Cherry Syrup, and ice. This beverage is sometimes referred to as a Shakerato, because of its foamy top. Egg white cocktails have a similar foamy top. Try making them at home for the ultimate summer drink. This recipe is refreshing and healthy, too!
