Definition of Brix

Categorized under "General"

Definition as written by darius:

Brix (written Bx) is an indication of the total soluble solids, minerals, vitamins and sugars in the sap of the leaves and fruit or seeds of the plant. Within a given species of plant, the crop with the higher refractive index Brix and crop maturity will have a higher sugar, mineral, and protein content, as well as a greater specific gravity of density and lower water content. This adds up to a sweeter-tasting, more mineral nutritious food with a lower nitrate and water content and better storage characteristics. Harvested fruits and vegetables with high Brix have shown better resistance to post harvest disease and lower water loss during storage. Crops with higher sugar content will also have a lower freezing point and therefore be less prone to frost damage.
