  2. LEMAK • Sapi • babi • unggas • binatangbuaslainnya gliserol Asamlemak

  3. lemak • Lemakbinatangadalahtrigliserida; a molecule of glycerol (C3O3H8) bonded to three fatty acids with ester linkages • Animal fat is not a waste product, it has multiple applications and is a valuable resource • PenilaianlemaksalahsatunyaadalahTitre: • Titre: This refers to the softness or hardness of a tallow or the temperature at which fats solidify. Fat of different species of animals, such as cattle, sheep (higher), and pigs (lower) have different titres. Within each particular animal, fats have different titres depending on location. For example, the titre of fat trimmed from the loin is different from kidney fat (higher).

  4. Pig 36-40°C (96.8-104°F) Cattle 42-45° C (107.6-113° F) Sheep 44-48° C (111.2-118.4° F) • Solidification points of animal fats, or titres, are as follows:

  5. Why rendering? • Raw animal fat can quickly become rancid. Therefore raw animal fat should not be saved and then converted into grease at some future date. The best procedure is to render animal fat into grease while the fat is still fresh. Rendered animal fat has a much longer storage life than raw animal fat.

  6. Rendering: • Adalahproses yang mengubahjaringanampas (jaringantidakberguna) hewanmenjadimateri yang stabilataudaribahan yang tidakbergunamenjadibahan yang berguna. • Atau melting animal fat • Penggunaan: • -sabun • -lilin • -pelembutdanpencerahpakaian • - waterproffing garment

  7. Produk rendering: • Generally: • - Tallow:rendered fat of cattle and sheep • - Lard:rendered fat of the hog • Penggunaan: • Animal fats add energy to livestock, poultry, and pet foods; improve color and texture, enhance palatability, increase pelleting efficiency, and reduce machinery wear in animal feed production.
