What is Xanthan Gum As a high viscosity water-soluble polymer, xanthan gum is a multifunctional food additive with many excellent physicochemical properties. Xanthan gum used as a common food additive such as thickeners, suspension agent, emulsifier and stabilizer in food industry with E number E 415. Its rheological properties make the juice have good perfusion and give the beverage refreshing characteristic. E415 food additive can be completely dissolved under low pH value, and the low concentration solution can effectively keep the flavor, concentration, taste and organization of the suspended pulp products stability for a long time. Xanthan gum E415 can improve the taste of fruit and chocolate drinks. Low concentrations xanthan gum solution can play a stabilizing role in low pH value as well as can be compatible with a variety of other ingredients (including ethanol) in beverages. At the same time, its stable effect is better than other gums. It has strong thermal stability, therefore general high temperature sterilization has no effect on it. Also, this food additive can be used for a variety of cold drinks, juice drinks, pulp beverages, instant solid drinks, etc., the dosage is 0.1%~0.4%. However, is there any xanthan gum substitute? Guar Gum: a Replacement for Xanthan Gum Xanthan gum usually derived from a variety of sources such as corn, wheat, or soy. People with an allergy to one of the above, need to avoid foods with xanthan gum, or to ascertain the source. Guar gum can be used to substitute for gluten in baking to render the dough springy and light. Due to its ability to attract water and thicken and bind gluten-free ingredients. Guar gum is made from the ground endosperm of the guar bean. Once the seeds are dehusked and ground, they are sieved to obtain the guar gum, which is a whitish powder. Guar gum is also a hydrocolloid and is a polysaccharide composed of sugars called mannose and galactose. The food industry is the largest market for guar gum. In the U.S., differing percentages are set for its allowable concentration in various food applications. Guar gum has EU food additive code E412 in Europe. Guar gum has about eight times the thickening ability of cornstarch, so it can be used to alternative to flour to thicken sauces. This xanthan gum substitute has similar properties to xanthan gum, as it can also be used as an emulsifier to help oil and vinegar combine, and as a stabilizer to prevent particles from settling in a liquid. Besides food industry, guar gum also used in textile, paper, pharmaceutical and cosmetics industries. The substitute ingredients can be Agar Agar, Gelatin, etc. OKCHEM will introduce these substitutes later! Related article: The top 10 Xanthan Gum world export countries in 2016
Gelatin is a type of protein derived from collagen obtained from various animal body parts. This translucent, colorless, brittle (when dry), flavorless food is commonly used as a gelling agent in food, pharmaceutical drugs, vitamin capsules, photography, and cosmetic manufacturing. It used as a thickener for fruit gelatines and puddings. The thickening, stabilizing and emulsifying agent xanthan gum added to foods such as ice cream, cream cheese, yogurt, or salad dressing acts as as a thickening, stabilizing and emulsifying agent. However, gum substitutes are generally gel-like in consistency and are much weaker in their structure. This lack of structure, produces baked goods that are denser because they aren't able to rise as well. Besides, people who have allergic to xanthan gum or dislike their texture in baked goods may choose substitutes. Gelatin is a water-soluble glutinous protein obtained from animal tissues, mainly pig skin. The thick jelly-like mixture used in food preparation make it acts like a sticky adhesive. Way to substitute Gelatin can be added directly to the dry powdered ingredients when in bread recipes. The amount of gelatin required in the recipe is twice as much as xanthan gum. For example, if your recipe calls for 1 tbsp of xanthan gum, add 2 tbsp of gelatin. It can be added directly to the dry ingredients in its powdered form - 1 tsp per 2 ½ cups of gluten-free flour in bread recipes. Can Gelatin for Vegans? Gelatin is a protein obtained by from animal tissues may be forbidden by members of particular religious groups, also people who have may have dietary restrictions should not eat gelatin. Gelatin is not vegan. The corn-based product xanthan gum is gluten-free, vegans can choose the gluten-free xanthan gum as an replacement in the recipe. Benefits of Gelatin Gelatin are commonly used to in the production of baked goods, such as breads and muffins. It gives extra protein and collagen and helps absorption of other minerals. In 2013, Health Canada approved a label for "hydrolyzed collagen" specifying that the label may say that it is useful to supplement dietary amino acid like glycine, it strengthen the gut lining and therefore lower inflammation. Doctors use glycine to help improve digestive, joint, cardiovascular, cognitive and skin health. What's more, adding gelatin to the diet to help alleviate food and other allergies.
