Like unprecedented is not a chemical ingredient or food ingredient, but a slogan or brand slogan.

It means "unprecedented" and is often used in marketing or advertising activities to convey the uniqueness, high quality or innovation of a company or product to consumers. For example, some companies will use "we provide unprecedented customer service" or "the quality of our products is unprecedented" to emphasize their differences and unique value from competitors.

As a brand slogan, the whole phrase is usually used to stimulate consumers' curiosity and interest to improve brand awareness and sales.
