Impurities of various kinds, including
color pigments, soaps, gums and albuminous matter, can cause
processing problems or poor quality in finished products for makers
of edible oils. BASF bleaching earths are highly effective in
removing these materials from a wide range of edible oils.
Our bleaching earths are activated clay adsorbents that provide
economic benefits to our customers due to superior capacity for
trapping undesired contaminants, hence, improving edible oil
quality, shelf life and stability.
BASF
Nevergreen™ specialty bleaching clay is an
acid-activated adsorbent, specially designed to enhance chlorophyll
removal from edible oils. It has superior activity for chlorophyll
removal with high carotenoid adsorption efficiency.
Nevergreen specialty bleaching earth enables bleaching in high
chlorophyll-containing oils such as soybean, sunflower, canola and
rapeseed where the oil processor requires low chlorophyll
levels.
In lab tests conducted by BASF, Nevergreen can achieve 6-50% dosage
reduction advantages over other bleaching earths in high
chlorophyll-containing (> 800 ppb) oils. In such oils, >95%
removal of chlorophyll is attainable.
