Experts say it's normal for fat in beverages such as walnut dew to rise, and this kind of beverage is safer. Is this true?

Vegetable protein drinks must contain milk fat (oil) and water. Everyone knows that oil and water are insoluble and the oil will float up. Adding emulsifier is the perfect solution to this problem. The rise of fat means that the emulsification system of the product is not well done, which does not mean that the product has deteriorated. You can even understand that the manufacturer has added less emulsifiers (this may not be the case).

But it's a drink, not milk. For products rich in milk fat, the phenomenon of oil slick is a difficult problem for dairy enterprises. Whether a product is done well depends largely on the emulsification system.
