There are many types of oils for frying. There are many brands and each has its own formula of ingredients. So how do you identify good quality sunflower oil?
First, check the ingredient label. Good quality cooking oil will be low in saturated fat and high in polyunsaturated fat. This balance of saturated and polyunsaturated fats is beneficial for your health. Your body requires a certain level of each type of fat that acts as fuel to maintain your energy levels throughout the day. Another key factor in good quality oil is that it will have little or no cholesterol. In the age in which we live, many of our foods contain incredible amounts of cholesterol. This means that you should use cholesterol-free ingredients to balance your daily food intake and minimize your risk of heart disease.
More ingredients to check are Antifoam and Antioxidants. Defoamer reduces or prevents excess foam that occurs during the oil frying process. Antioxidants increase the shelf life of cooking oil, making it safe and healthy to use even after a certain period of time. However, always check the oil’s expiration date before using it.
Sunflower oil naturally has a high heat threshold, which means that even at high temperatures it remains stable. In other words, its goodness is not compromised when it reaches a high level of heat. The ingredients will not be affected by heat.
Other physical attributes to check in terms of the quality of your sunflower oil are the color and smell of the oil. It should be a light, translucent golden yellow color. It should not be cloudy or foamy. The clarity of the oil is very important. There should be no flakes or chunks of any kind in the oil. It should have a smooth, flowing consistency. For this same reason, it is better not to reuse the oil. These benefits are nullified once the oil has been used and can adversely affect your health. Fresh oil is always better.
You will find that most sunflower oil manufacturers take great care in offering you a good quality product and will ensure that all health and safety standards are met. But as a consumer, you need to know what is in a good quality cooking oil. You need to be informed so that you can make the best decision for you and your family.
