What causes soybean oil to foam?
The issue of soybean oil foaming has been the subject of much discussion on social media and cooking forums recently. Many housewives and chefs find that soybean oil tends to produce a lot of foam during cooking, which affects the taste and appearance of the dishes. This article will combine the hot topics and hot content on the Internet in the past 10 days to conduct an in-depth analysis of the causes of soybean oil foaming and provide solutions.
1. The main reasons for foaming in soybean oil
According to recent discussions among netizens and analysis by professional chefs, the main reasons for foaming in soybean oil are as follows:
| Reason | Specific instructions |
|---|---|
| Oil temperature is too high | When the oil temperature exceeds 200°C, the protein and phospholipids in soybean oil will decompose and produce foam. |
| Impure oil | Low-quality soybean oil may contain more impurities, such as residual bean dregs or moisture, which can easily cause foaming. |
| Repeated use | Soybean oil that has been used multiple times will accumulate food residue and oxidation products, increasing the likelihood of foaming. |
| Effects of cooking ingredients | When certain ingredients (such as eggs, starchy foods) come into contact with soybean oil, a chemical reaction will occur and foam will occur. |
2. How to avoid soybean oil foaming
For the above reasons, the following measures can be taken to reduce the foaming of soybean oil:
| Solution | Specific operations |
|---|---|
| Control oil temperature | Use a thermometer to monitor the oil temperature and avoid exceeding 180°C. |
| Choose high-quality soybean oil | Buy refined soybean oil from a reputable brand to ensure the oil is pure. |
| Change oil regularly | Avoid using the same batch of soybean oil repeatedly. It is recommended to replace it with new oil after every 3-4 uses. |
| Preprocessing food | Wipe away the moisture on the surface of the ingredients, or wrap them in a thin layer of starch to reduce direct reaction with oil. |
3. Content hotly discussed by netizens
In the past 10 days of social media discussions, netizens shared their own coping experiences. Here are some popular comments:

Well-known chef Master Zhang said in an interview: "Foaming in soybean oil is a common phenomenon, but it can be avoided by the following professional skills: First, the new oil can be heated to about 150°C and then cooled before use, which can remove some impurities; secondly, when frying food, do not put too much at once and keep enough space in the oil pan; finally, you can add a few Sichuan peppercorns to the oil to help defoaming."
5. Relevant data statistics
