Do thickeners have any nutritional value? Thickeners
As a supplier of thickeners, I’ve often been asked this question. Thickeners are substances that increase the viscosity of a liquid without substantially changing its other properties. They are widely used in various industries, including food, pharmaceuticals, and cosmetics. In this blog post, I’ll delve into the topic of whether thickeners have any nutritional value.
Types of Thickeners and Their Sources
Before we discuss nutritional value, it’s important to understand the different types of thickeners and where they come from.
- Starch – Based Thickeners
- Starch is one of the most common thickeners. It is derived from sources such as corn, wheat, potato, and tapioca. When heated in a liquid, starch granules absorb water, swell, and rupture, releasing amylose and amylopectin, which then thicken the liquid. For example, cornstarch is widely used in cooking, from making sauces to thickening pie fillings.
- Gums
- Gums are polysaccharides that can form viscous solutions or gels. Common gums used as thickeners include xanthan gum, guar gum, and carrageenan. Xanthan gum is produced by the fermentation of glucose or sucrose by the bacterium Xanthomonas campestris. Guar gum is derived from the seeds of the guar plant, and carrageenan is extracted from red seaweeds.
- Protein – Based Thickeners
- Gelatin is a well – known protein – based thickener. It is made by boiling the collagen found in animal skin, bones, and connective tissues. In the food industry, it is used in products like jelly desserts and marshmallows.
Nutritional Value of Starch – Based Thickeners
Starch is a complex carbohydrate. When digested, it is broken down into glucose, which is then used by the body as a source of energy. A 1 – tablespoon serving of cornstarch (about 8 grams) provides approximately 30 calories, all of which come from carbohydrates. It has no fat, protein, or significant amounts of vitamins or minerals.
However, the type of starch can make a difference in its nutritional impact. For example, whole – grain starches like wheat and some varieties of corn also contain fiber, which is beneficial for digestive health. Fiber can help regulate bowel movements, lower cholesterol levels, and control blood sugar. So, if the thickener is made from whole – grain starch, it can contribute some nutritional value in terms of fiber content.
Nutritional Value of Gums
Gums, in general, do not have a high nutritional value in the traditional sense of providing macronutrients like carbohydrates, proteins, or fats. But they do have some health benefits.
- Dietary Fiber
- Many gums are considered dietary fibers. Xanthan gum and guar gum, for instance, are soluble fibers. Soluble fiber can absorb water in the digestive tract, forming a gel – like substance. This can slow down digestion, making you feel full for longer periods, which may aid in weight management. It can also help regulate blood sugar levels by slowing the absorption of glucose and can lower cholesterol levels by binding to bile acids in the gut.
- Prebiotic Effects
- Some gums can act as prebiotics. Prebiotics are substances that stimulate the growth and activity of beneficial bacteria in the gut. Guar gum, for example, can be fermented by gut bacteria, promoting the growth of probiotic bacteria such as Bifidobacteria and Lactobacilli, which are beneficial for gut health.
Nutritional Value of Protein – Based Thickeners
Gelatin is rich in protein, specifically collagen. A 1 – tablespoon serving of gelatin (about 6 grams) provides approximately 23 calories, all from protein. Collagen is an important structural protein in the body, found in the skin, bones, tendons, and ligaments. It helps maintain the elasticity and strength of these tissues.
As we age, our body’s natural production of collagen declines. Consuming gelatin – based products can be a way to supplement the body’s collagen levels, which may have benefits for joint health, skin elasticity, and hair and nail strength.
Thickeners in the Food Industry: Nutritional Considerations
In the food industry, thickeners are often used in combination with other ingredients. While the thickener itself may have some nutritional value, it is important to look at the overall nutritional profile of the product.
- Processed Foods
- In many processed foods, thickeners are used to improve texture and stability. However, these products may also be high in sugar, salt, and unhealthy fats. For example, a cream – based soup thickened with a starch – based thickener may taste rich and creamy but could also be loaded with calories, sodium, and saturated fat. In such cases, the small amount of nutritional value provided by the thickener may be overshadowed by the negative nutritional aspects of the other ingredients.
- Healthy Food Applications
- On the other hand, thickeners can also be used in healthy food products. For example, in a smoothie made with natural fruits, yogurt, and a small amount of xanthan gum for thickness, the thickener contributes to the smooth texture without adding unwanted calories or compromising the nutritional value of the overall product.
Thickeners in the Pharmaceutical and Cosmetic Industries
In the pharmaceutical and cosmetic industries, thickeners are used mainly for their functional properties rather than their nutritional value. In pharmaceuticals, they are used to control the release of drugs, improve the stability of formulations, and provide a pleasant texture. In cosmetics, they are used to thicken creams, lotions, and gels to improve their spreadability and consistency.
While these industries do not typically focus on the nutritional content of thickeners, it is worth noting that some thickeners used in these sectors, such as certain natural gums, may have potential health benefits if they happen to come into contact with the body’s physiological systems (e.g., through oral intake of a pharmaceutical product or absorption through the skin in a cosmetic application).
Conclusion
In summary, thickeners can have some nutritional value depending on their type. Starch – based thickeners can provide energy in the form of carbohydrates, and whole – grain starches can contribute fiber. Gums can act as dietary fibers and prebiotics, while protein – based thickeners like gelatin can provide a source of collagen.
However, it’s important to note that the nutritional value of thickeners is often just a small part of the overall picture, especially when they are used in complex food products. When considering the impact on health, it’s crucial to look at the whole product and its overall nutritional profile.
