Apeeling Potato

Antioxidant-mediated protective effect of potato peel extract in
erythrocytes against oxidative damage. [JOURNAL ARTICLE]
Chem Biol Interact 2008 Mar 22.

Potato peels are waste by-product of the potato processing industry.
They are reportedly rich in polyphenols.
Our earlier studies have shown that extracts derived from potato peel
(PPE) possess strong antioxidant activity in chemical and biological
model systems in vitro, attributable to its polyphenolic content.
The main objective of this study was to investigate the ability of PPE
to protect erythrocytes against oxidative damage, in vitro. The
protection rendered by PPE in erythrocytes was studied in terms of
resistance to oxidative damage, morphological alterations as well as
membrane structural alterations.
The total polyphenolic content in PPE was found to be 3.93mg/g
powder.
The major phenolic acids present in PPE were predominantly: gallic
acid, caffeic acid, chlorogenic acid and protocatechuic acid.
We chose the experimental prooxidant system: FeSO(4) and ascorbic acid
to induce lipid peroxidation in rat RBCs and human RBC membranes.
PPE was found to inhibit lipid peroxidation with similar effectiveness
in both the systems (about 80-85% inhibition by PPE at 2.5mg/ml).
While PPE per se did not cause any morphological alteration in the
erythrocytes, under the experimental conditions, PPE significantly
inhibited the H(2)O(2)-induced morphological alterations in rat RBCs
as revealed by scanning electron microscopy.
Further, PPE was found to offer significant protection to human
erythrocyte membrane proteins from oxidative damage induced by ferrous-
ascorbate.
In conclusion, our results indicate that PPE is capable of protecting
erythrocytes against oxidative damage probably by acting as a strong
antioxidant.

It may depend on the specific food processing
plant deals with potato skins. Some spray hot
lye on the potatoes and then pressure wash the
caustic soften skin off while others I believe
steam flash the skin and pressure wash the
soften skin off. When the trimming of the
potatoes is done by either human or
photoelectric sorting the potato is stripped
to white interior and a few black spots.
Trimmings are cow feed, the rinse water is
a source of starch for the paper industry,
and fragments go to either composite
potato products or are used as more
animal feed. And the waste of this
waste likely is used to make methane.
