Firstly I must say I like Old Chang Kee food. Tasty abeit unhealty.
But I notice they have being steady increasing their prices. When there is GST hike, they increased the prices. When there is no GST hike, they also increase their prices. (most of the time by 10cents, 20cents each time)
A curry puff now costs S1.10. When I think about it, the food no long justify the cost. Hence I rarely patronise Old Chang Kee nowadays.
How about u guys? or u all cannot resist the food by Old Chang Kee.
Reheated oil very carcinogenic.
I seldom eat these days.
DEEP FAT FRYERS DANGERS: These pose a high risk because a deep-fat fryer will give off high EMFs as the oil is heated. Regularly reheated oil is likely to contain carcinogenic compounds generated at the high temperatures, which will then attach themselves to the fried food.
SOLUTIONS: You should avoid deep-fat frying.
RISK RATING: 5

I have some oil for deep frying -- used only once -- that has been in the refrigerator for eight months. Can I still use it? - Barbara Leonard (4/19/01)
Question:
We use vegetable and canola oil in our home for cooking. I'm disabled and on a very small budget and would appreciate any advice about cleaning the oil for re-use, hopefully to remove sediment, discoloration and odor. Thank you. - Mike and Brenda (11/05/06)

Answers:
I, personally, never reuse cooking oils. The foods you cook the oils in will cause the oils to go rancid faster.
A recent study found that a toxin called 4-hydroxy-trans-2-nonenal (HNE) forms when such oils as canola, corn, soybean and sunflower oils are reheated. Consumption of foods containing HNE from cooking oils has been associated with increased risks of cardiovascular disease, stroke, Parkinson'?s disease, Alzheimer's disease, Huntington's disease, various liver disorders, and cancer. Once absorbed in the body, HNE reacts with DNA, RNA and proteins affecting basic cellular processes.
That being said:
Reusing cooking oil has been done for ages. There really isn't a problem, if done properly. The greatest hazard is allowing the fat to become rancid (spoiled) and deteriorated to the point it produces undesirable flavors and odors. Besides ruining what would have been a perfectly good meal, rancid oils also contain free radicals that are potentially carcinogenic. Rancid oil has fewer antioxidants but is not poisonous.
