In 2 studies of 76 adults delayed stomach emptying but had no effect on blood sugar levels [ 40, 22]. In cosmetic products, pectin acts as a stabiliser. Pectin is also used in wound healing preparations and speciality medical adhesives, such as colostomy devices. The process of making jam and jelly involves a chemical reaction between pectin, sugar, and acid in the fruit. When using fruit low in acid content, the gelling process can be completed by adding lemon juice to your recipe. Among the many things we’re passionate about, quality and consistency sit high on the list. We work to control the structural parameters of our ingredients by selecting the appropriate raw materials and processing conditions. Nearly every batch of pectin we produce is standardized to consistently deliver high quality. From these materials, pectin is extracted by adding hot dilute acid at pH values from 1.5 to 3.5. During several hours of extraction, the protopectin loses some of its branching and chain length and goes into solution. After filtering, the extract is concentrated in a vacuum and the pectin is then precipitated by adding ethanol or isopropanol. An old technique of precipitating pectin with aluminium salts is no longer used (apart from alcohols and polyvalent cations, pectin also precipitates with proteins and detergents).
A high-pectin diet (enteral liquid 2:1 v/v) reduced the number and duration of reflux episodes in a clinical trial on 18 children with cerebral palsy and acid reflux [ 25]. Sriamornsak, P. (2011).

However, the conventional treatment with omeprazole was more effective in another trial on 77 people [ 29].CONDITIONS OF USE AND IMPORTANT INFORMATION: This information is meant to supplement, not replace advice from your doctor or healthcare provider and is not meant to cover all possible uses, precautions, interactions or adverse effects.

Additionally, some animal studies have revealed that these supplements improve the health of gut bacteria, which can decrease inflammation and improve gastrointestinal symptoms ( 17, 32, 38). Researchers theorize that pectin can decrease colon cancer risk by binding with and inhibiting the absorption of galectin-3, high levels of which are associated with an increased risk of colon cancer ( 22, 23).
To prepare a pectin-gel, the ingredients are heated, dissolving the pectin. Upon cooling below gelling temperature, a gel starts to form. If gel formation is too strong, syneresis or a granular texture are the result, while weak gelling leads to excessively soft gels.
Although the results are promising, 2 clinical trials cannot be considered sufficient evidence. More clinical research is needed to validate their results. 5) Constipation However, more research in humans is needed to better understand how pectin affects blood sugar and fat levels. Decreases colon cancer risk In nature, around 80 percent of carboxyl groups of galacturonic acid are esterified with methanol. This proportion is decreased to a varying degree during pectin extraction. Pectins are classified as high- versus low-methoxy pectins (short HM-pectins versus LM-pectins), with more or less than half of all the galacturonic acid esterified. [21] The ratio of esterified to non-esterified galacturonic acid determines the behaviour of pectin in food applications – HM-pectins can form a gel under acidic conditions in the presence of high sugar concentrations, while LM-pectins form gels by interaction with divalent cations, particularly Ca 2+, according to the idealized ‘egg box’ model, in which ionic bridges are formed between calcium ions and the ionised carboxyl groups of the galacturonic acid. [22] [23] [21] Typical levels of pectin used as a food additive are between 0.5 and 1.0% – this is about the same amount of pectin as in fresh fruit. [31]
This homemade pectin can be stored for approximately one week in the refrigerator, can be frozen, or can be processed in a boiling water bath for longer shelf life.

In another clinical trial, 18 children with cerebral palsy received a diet either high (enteral liquid 2:1 v/v) or low (enteral liquid 3:1 v/v) in pectin. After 4 weeks, the high-pectin diet reduced vomiting [ 25]. Tapioca is one of the healthier options for kids as a substitute for commercial pectin. It is extracted from cassava tubers which makes it a natural carbohydrate. Cassava tubers are native to South America but are known as Yuca in the United States.

In rats, modified citrus pectin reduced the spread of prostate cancer, but not primary tumor growth [ 61].Pectin is also used as a soluble fiber supplement, which is often sold in capsule form. Soluble fiber may help relieve constipation, lower cholesterol and triglyceride levels, improve blood sugars, and promote a healthy weight ( 5).
