Gelatin - A substitute for Xanthan Gum


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.

2016 Chinese Food Additives Industry Overview-1

Potassium sorbate

In 2016, Chinese food additives and ingredients industries kept smooth growth, although the over economic background and demand capacity was generally weak and soft. The overall production and revenue increase were slow in the first half of last year, however, the situation was improved in the following half year and both production and revenue had a fast pace of growth. Based on the analyses of major categories of food additives, the total production quantity of Chinese food additives in 2016 was almost 11 million metric tons, increased 6% compared to that of 2015; total revenue increased 5.8% and was about 104 billion yuan; export revenue was 3.8 billion U.S. dollars, which about the same as that of 2015. Below is more detailed analysis about food additives in different categories.

Edible Flavors and Fragrances
 
Edible flavors and fragrances was upward in 2016 but the growth was not as fast as previous years, with about 8% growth rate of sales and slight better performance of export amount compared to 2015. Savory flavoring production and sales also had small amount of increase, however, yeast extract, among other savory flavoring stuff, had an outstanding 10% production and 15% sales increase. The development of Chinese domestic baked and fermented food, flavoring products provided a strong support to this category.

Food Preservative and Antioxidant
 
Production and sales of food preservative and antioxidant went up in 2016. Staple commodity toluic acid and toluic acid sodium had about the same production and sales volume compared to last year. The market demand of natural preservatives like nisin, natamycin and polylysine increased: production and export amount of nisin grew greatly and natamycin production had an over 20% increase, while the sales was over 15%. New product polylysine had more than 200% increase in terms of both production and sales amount. Global and domestic usage of potassium sorbate was steady as year of 2015, however the prices were volatile due to the higher cost of the raw material crotonaldehyde. Domestic sales of sodium dehydroacetates was boosted 10-20% and prices were upward. Parabens were greatly demanded in the global market, especially in personal care industry.

In 2016, the demand of compound preservatives was 10% more than before. Some small and medium scale companies don’t have strong technical ability, therefore they’re more rely on compound products. Product renovation and application of compound preservatives will be a trend in the future.

Sweetening Agents
 
High intensity sweeteners’ production amount was 8% lower in 2016. Domestic sales of stevioside was about the same as 2015 and slight increase for export sales because of the higher consumption and demand from the U.S. market. The production, revenue and sales price of saccharin were steady like last year. The cost of sodium cyclamate dropped as the international oil price changed, meanwhile, the production and sales also decreased. Acesulfame potassium was also effected by the lower demand of the market. The worse situation was in November 2016, when three major Chinese manufacturers were audited by the U.S., therefore the export and sales margin were not positive. Aspartame price was keeping low last year. Price of sucralose was going upward, however the production and export amount were low because of stringent environmental regulations. Sales prices of xylitol, xylose, maltitol and erythritol climbed in a small range due to the raw material price raise. The domestic demand was stable and export was soft. Read more!
