Animal Tallow Supply Solutions
Animal tallow – a rendered form of fat which includes beef tallow, pork lard, and chicken fat – is an increasingly attractive feedstock option for biodiesel manufacturers in North America and Europe due to its availability, comparatively low cost, and high cetane number (an important quality parameter for diesel fuel). As an ISCC-certified global supplier of biofuel materials, Targray is well-positioned to help meet the international biodiesel sector’s growing need for affordable feedstocks like tallow.

TITRE:
The TITRE determines the solidification point of fatty acids and is expressed in degrees centigrade (˚C). For practical purposes the TITRE can be considered as a measure of the hardness or softness of the material in question.F.F.A.:
Means Free Fatty Acid. It is customarily reported in percentage of Oleic Acid.FAC:
Stands for Fat Analysis Committee. This method determines the Color of Fats and Oils by comparison with AOCS FAC color standards.R & B Color:
Is the color after Refining and Bleaching and is expressed in terms of Red on a 5 1/4 inch cell or tube of AOCS methods.M.E./K:
Peroxide Value is expressed in Milli Equivalents per Kilo and is a measure of Fat Oxidation.M.I.U.:
These common tests often grouped together and referred to as MIU content are:(M)— Moisture and Volatile Matter
(I)— Insoluble Impurities
(U)— Unsaponifiable Matter
All three are reported as percentages and serve to measure the amount of non-fatty matter present.
I.V.:
Stands for Iodine Value. The iodine value is a measure of the unsaturation of fats and oils and is expressed in terms of the number of centigrams of iodine absorbed per gram of sample.(Information provided by the American Fats and Oils Association)
