Choosing Quality Cooking Oil: Tips from Edible Oil Filling Machine Manufacturer

Choosing the right cooking oil is essential for both health and culinary purposes. Amid the multitude of cooking oil brands and types available in the supermarket, HZM Machinery, a manufacturer of edible oil filling machines, offers practical tips for selecting cooking oil, helping you navigate the supermarket's overwhelming selection:

1. Observe the Color: Generally, the higher the refinement level, the lighter the color of the cooking oil. However, it's important to note that each type of vegetable oil has its distinct color, and there's no need to refine the oil to the point of having no color.
2. Check Transparency: Opt for cooking oil that is clear and transparent; higher transparency is often a sign of purity.
3. Smell for Odors: Take a drop or two of oil and rub it between your hands to generate heat. Then, smell the oil. Authentic cooking oil should not have any unusual or unpleasant odors. If you detect any strange odors, it's best to avoid purchasing it.

In terms of identifying the authenticity of cooking oils, there are some additional methods:

1. Detecting Adulteration: Some unscrupulous individuals may adulterate cooking oils. Adulterated oils typically result in reduced transparency. You can pour the oil quickly from the bottle into a cup and observe the patterns formed by the oil. Genuine peanut oil should produce larger, longer-lasting bubbles with no distinct color, while oils blended with cottonseed or sesame oil might have bubbles slightly tinged with green, yellow, or brown. Additionally, if you detect the smell of cottonseed oil, it is likely adulterated. Furthermore, oils adulterated with starch-based substances may develop cloudy suspensions when left in a transparent cup for a couple of days.
2. Checking for Adulterated Toasted Sesame Oil: Adulterated toasted sesame oil often results in a darker color. For instance, toasted sesame oil adulterated with cottonseed oil may appear dark red, while adulteration with rapeseed oil may lead to a deep yellow hue. Authentic toasted sesame oil typically does not create oil patterns when poured, and any patterns that do form tend to dissipate rapidly. If the oil patterns persist for an extended period, it may indicate adulteration. You can also dip a chopstick into a drop of oil and place it on a calm water surface. Authentic toasted sesame oil will form thin, colorless patterns, while adulterated oil will produce thicker, colored patterns.

By employing these techniques, you can confidently select the cooking oil that best suits your needs while avoiding low-quality or adulterated products.
