Dear Subscriber,
Glycoalkaloids in potato was the topic
of a number of newspaper articles recently , since
the
Journal of the Science of Food and Agriculture
published a review on glycoalkaloids in potato and
potato products. Although most of us prefer
to read newspaper articles that educate the general public
on the numerous nutritional benefits of the potato, the
attention to glycoalkaloids may serve the potato industry
well.
As far as I am aware, potato glycoalkaloids have
not been a problem anywhere – and have not been for a while.
Hence, the current attention to glycoalkaloids may serve as
a useful reminder to keep paying attention to this issue and
keep that record.
Glycoalkaloids are naturally present
toxins, that probably evolved as protective compounds in
response to tissue damage. Glycoalkaloids have
anti-microbial, insecticidal and fungicidal properties. In
low concentrations glycoalkaloids can have a positive impact
on flavour. However, in higher concentration glycoalkaloids cause a
bitter taste and can be toxic.
Both consumers and potato industry can
take a number of precautions to keep the risks of
glycoalkaloids negligible. Here is a list with suggestions
of what various players in the potato supply chain can do:
|
Consumers
- Discard sunburned potatoes
- Cut away green potato
- Do not eat bitter potatoes or
potato products
- Do not eat potato sprouts or
sprouted potatoes
|
Potato Processors
-
Remove
green/sunburned potato flesh, potato sprouts
- Avoid mechanical injury, bruising,
wounding, cutting, slicing during handling prior to
processing
- Special care is required for skin-on
potato products
|
|
Farmers
-
Keep potatoes well covered
with soil during growth
- Allow tubers to
mature before harvest
- Avoid harvest at
very high temperatures and under bright sunlight
- Suppress sprouting of potatoes
- Avoid mechanical injury, bruising, wounding cutting,
slicing during handling
|
Potato Packers
-
Discard sunburned
tubers
- Minimize tuber exposure to light
during grading and other operations
- Avoid
mechanical injury, bruising, wounding cutting,
slicing during handling
- Pack potatoes in materials
which protect them from light
|
|
Retailers
-
Store tubers in the dark
-
Display potatoes packed in materials which
protect them from light
|
Breeders/Agencies that decide on the
introduction of new varieties
- Select
potato cultivars with low tendency to form glycoalkaloids
|
