The ash content of pectins extracted from various banana peels was between 1.38 and 2.87% which was in similar range to that obtained from the conventional pectin sources, citrus peel (3.46%) and apple pomace (1.96%). The ash content indicates the purity of the pectin. Lower ash content means higher purity.
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).
What is the total pectin content of ripe banana pulp?

What is banana pectin?
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 is pectin extracted?
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]. Citrus fruits contain 0.5–3.5% pectin which is largely present in the peel of fruits .

How long does it take for a banana peel to turn black?
If the banana has its peel still on, it will start turning brown three to five days after ripening especially if they are still in a bunch. Browning of an unpeeled banana happens because once the fruit has ripened, the production of ethylene does not stop.
Why do banana shakes turn black?
