Abstract

L'invention a trait au domaine de l'industrie alimentaire Elle concerne un silicate de calcium hydraté synthétique en particules nettement plus grossières, avec des vitesses d'écoulement bien plus grandes et de plus faibles teneurs en calcium liposoluble que les silicates de calcium hydratés synthétiques de l'art antérieur. Les silicates de l'invention, qui sont obtenus par réaction hydrothermique d'oxyde de calcium et de silice, contiennent au minimum 8 % de particules traversant un tamis de 44 mu m d'ouverture de maille, et ils ont une perméabilité d'environ 0,35 à 0,70 unité Darcy et une teneur en calcium liposoluble n'excédant pas 60 parties par million. Application à la filtration d'huiles telles que les huiles de cuisine pour en réduire la teneur en acides gras libres.The invention relates to the field of the food industry It relates to a synthetic hydrated calcium silicate in much coarser particles, with much higher flow rates and lower contents of fat-soluble calcium than synthetic hydrated calcium silicates. of the prior art. The silicates of the invention, which are obtained by hydrothermal reaction of calcium oxide and silica, contain at least 8% of particles passing through a sieve of 44 μm mesh opening, and they have a permeability of approximately 0.35 to 0.70 Darcy units and a fat soluble calcium content not exceeding 60 parts per million. Application to the filtration of oils such as cooking oils to reduce the content of free fatty acids.
