Sweeteners are food additives that impart a sweet taste to food or beverages and can be used in a wide variety of food products such as bread, pastries, cookies, beverages, and condiments. The following is a detailed introduction to sweeteners:
1. Definition and Classification
Sweeteners are mainly embodied in food in three aspects, including making food with suitable taste, flavor regulation and enhancement, and flavor formation. According to the source and nature, sweeteners can be divided into the following categories:
Mono- and disaccharides: such as sucrose, glucose, fructose, maltose, lactose, etc., which are natural sugars.
Oligosaccharides: such as oligoisomaltose, oligofructose, oligogalactose, etc., they are composed of 2 to 10 monosaccharide molecules, the sweetness is lower, but the calorie is also relatively low.
Sugar alcohols: such as sorbitol, maltitol, mannitol, lactitol, erythritol, xylitol, etc., they have a sweet flavor, but the calories are lower, and less impact on blood sugar.
Chemical synthetic sweeteners: such as saccharin, sweeteners, aspartame, sucralose (sucralose), etc. These sweeteners are very sweet, usually hundreds or even thousands of times that of sucrose, but with very low or no calories.
2. Role and efficacy
Sweeteners play an important role in food and beverages, mainly including the following aspects:
Increasing sweetness: Sweeteners can give foods and beverages a sweetness similar to that of sugar, thus enhancing their taste and popularity.
Reducing calorie intake: Sweeteners have a lower calorie content compared to sugar, so they can help people reduce the number of calories they consume, which can be very beneficial for weight control and prevention of diseases such as diabetes.
Enhanced stability: Sweeteners can provide a stable taste and texture in foods and beverages, while also preventing food spoilage and rancidity.
Extended shelf life: Foods and beverages with added sweeteners usually stay fresher for a longer period of time because sweeteners prevent food spoilage.
3. Safety and health effects
Although sweeteners are widely used in foods and beverages, there have been controversies about their safety and health effects. Some studies have suggested that excessive intake of certain sweeteners over a long period of time may have negative effects on human health, such as increased risk of obesity, diabetes, and cardiovascular diseases. However, the results of these studies are not consistent and are controversial.
Therefore, when using sweeteners, attention should be paid to their safety and health effects, and sweeteners should be used wisely. It is important for consumers to understand the types, effects and health effects of sweeteners in order to make informed dietary choices. At the same time, food processing companies should also comply with food safety regulations to ensure that the use of sweeteners complies with relevant regulations and standards.
4. Introduction of Common Sweeteners
Aspartame: It decomposes into aspartic acid and phenylalanine and trace methanol in the human body, which are naturally found in fruits, vegetables, meat and eggs. Aspartame does not tolerate high temperatures or acidic conditions and cannot be used in baked goods that are heated for long periods of time.
Sucralose: Similar in taste to sucrose and about 600 times sweeter. It does not participate in human metabolism, does not provide energy, and can be consumed by diabetics.
Erythritol: has excellent taste and stability, small hygroscopicity, low melting point, commonly used in confectionery foods, can prevent moisture and humidity and extend the shelf life.
