Pectin can be extracted from various kinds of fruits, but the most commercial form of pectin is extracted from the peels of citrus fruits by alcohol precipitation [9, 25]. … The most commonly used method for extracting pectin from plant tissue is by heating the plant sample in acidified water.
How is pectin obtained?
Pectin is a group of substances which forms gels when dissolved in water under suitable conditions. It is derived from the protopectin found in the middle lamellae of plant cells. Protopectin is insoluble, but is converted to soluble pectin as fruit ripens or is heated in an acid medium. … (See PECTIN | Food Use.)
How do you extract pectin from orange peels?
- Peel the oranges. …
- Cut the orange peel into narrow strips and use a knife to remove the white part of the peel, also known as the pith.
- Dice the pith into small pieces.
- Add 2 tablespoons of lemon juice to the chopped pith.
How do you extract pectin from a banana peel?
Pectin extraction was carried out using hydrochloric acid (0.5N, pH 1.5) and citric acid (0.5N, pH 1.7). Pectin from the acidified fruit peels were extracted at 90±5°C for 1, 2, 3 and 4 hours. Highest pectin yield was obtained using HCl extracted for 4h (17.05% dry basis).
Why do we use acid in extraction of pectin?
Acids are the strongest extracting agents of pectin as they facilitate extraction of insoluble pectin that is tightly bound to the cell matrix of the plant material and result in higher yields [35-37].
Why is pectin bad for you?
It is POSSIBLY SAFE when used in larger amounts. When taken by mouth alone or in combination with insoluble fiber (the combination used to lower cholesterol and other blood fats), pectin can cause stomachcramps, diarrhea, gas, and loose stools.
What fruit is pectin found in?
For example, apples, carrots, oranges, grapefruits, and lemons contain more pectin than cherries, grapes, and other small berries with citrus fruits containing the most pectin.
Can I use lemon juice instead of pectin?
Replace Store-Bought Pectin with Lemon Seeds
For moderate-to-high pectin fruit, the latter method is best, especially if you add lemon juice to stay on the safe side. For low-pectin fruit, though, make a concentrate out of 5 to 7 lemon seeds and one cup of water for every 7 oz of jam.
What can I substitute for pectin?
- Citrus peels. Citrus peels—especially the white part, or pith—are naturally packed with pectin. …
- Cornstarch. Cornstarch is a natural thickener that works as a seamless substitute for pectin.
- Gelatin. Gelatin is a viable option for non-vegans or non-vegetarians.
- Extra sugar.
How much pectin is in an orange peel?
Orange peel, which constitutes approximately 45% of the total bulk of the processed citrus fruit (Kesterson &, Braddok, 1975) is a good source for the extraction of pectin. It contains, on a dry matter basis, about 30% pectin (Bravemann, 1949, Rouse &, Crandall, 1976).
Do banana peels have pectin?
The yield of banana peel pectins ranged from 15.89 to 24.08%. The extracted banana peel pectins were categorized as high methoxyl pectin with the degree of esterification between 63.15 and 72.03% comparable to those of conventional pectin sources from citrus peel (62.83%) and apple pomace (58.44%).

How much pectin is in a banana?
Pectin content of fully ripe bananas has been reported to range between 0.5 to 1.28% (Baker, 2006), which is in agreement with pectin yield at ripening stages 5 and 7 of this study.
What is pectin based?
Pectin-based – Pectin comes primarily from citrus fruits and apples. It is a nutritional fiber and works to help enhance the bio-availability of the vitamins and minerals.
What food has the most pectin?
Apples and citrus fruits — such as peaches, oranges, grapefruits, apricots, and lemons — contain the highest amount of pectin among fruits. And among vegetables, carrots, tomatoes, and potatoes are those with the most pectin. Peas have the highest pectin concentration among legumes.
What is pectin made of?
Pectin is completely plant-based and suitable for anyone who’s vegan or vegetarian. Most pectin is made from apples or citrus fruits.
How do you separate fruit and pectin?
The extraction of pectin involves the hydrolysis of insoluble protopectin into soluble pectins and then leaching them out of fruit tissues.
