1 Scope
This standard specifies two methods for determination of moisture and volatile matter in animal and vegetable fats and oils.
The first method of this standard [Sand Bath (Electric Heating Plate) Method] applies to all animal and vegetable fats and oils; the second method (Electrically Heated Drying Oven Method) is only applicable to non-dry fats and oils with acid value less than 4mg/g, not applicable to lauric acid type oil (palm kernel oil and coconut oil).
Method I Sand Bath (Electric Heating Plate) Method
2 Principle
Under the conditions of 103 ± 2℃, the test sample is heated until moisture and volatile matter are completely dispersed and then determine the mass loss of the sample.
3 Apparatus
3.1 Analytical balance: sensitivity of 0.001g.
3.2 Dish: made of ceramic or glass flat bottom dish, in diameter of 80mm/90mm, with depth of about 30mm.
3.3 Thermometer: graduated range is at least 80°C~110°C, with length of about 100mm, mercury ball reinforced and expansion chamber at the upper end.
3.4 Sand bath or electric hot plate (room temperature~150°C).
3.5 Dryer: contains an effective desiccant.
