What benefits does the use of food-grade defoamers bring?
Foam in food is often dismissed as a minor issue in everyday life, rarely drawing much attention. However, when it appears during processing, it becomes a significant concern. The presence of foam not only reduces processing efficiency but also degrades the product’s texture and mouthfeel. Consequently, the use of food-grade defoamers is essential.

How much do you know about the characteristics of common antifoaming agents?
Foam is inherently very unstable; for example, when a liquid is stirred, foam forms but disappears as soon as the agitation ceases. However, in industrial processes, the presence of foam‑stabilizing substances makes it considerably more difficult for the foam to dissipate on its own. The purpose of adding a defoamer is precisely to eliminate the stable foam generated by these stabilizing agents.

The principle by which defoamers eliminate foam
The principle originates from sprinkling high‑proof alcohol or edible oil onto the foam. When these substances mix with the foam liquid, they significantly reduce the surface tension in that area. Because these chemicals are typically poorly soluble in water, the reduction in surface tension is confined to the foam‑plastic component, while the surface tension around the foam remains largely unchanged. The portion where the surface tension is lowered—clearly the surrounding tensile band—widens and eventually ruptures.

JYS8859 is suitable for napping and raising‑pile finishing, and can also be used for lubricating and finishing sewing threads and various other yarns. Under normal application conditions, JYS8859 has minimal impact on the whiteness of white fabrics and on the color shade and color fastness of colored fabrics. JYS8859 may be used alone or in combination with other softening agents; please conduct compatibility tests prior to use.

JYS8360 is an oil-in-water polydimethylsiloxane emulsion, appearing white in color and suitable for cold‑mixing processes. Compared with conventional organic silicone release agents, JYS8360 offers superior release performance, while also exhibiting excellent emulsion stability and dilution stability, strong compatibility, and enhanced stability and ease of use during application.
