Foreword

This standard is identical with ISO 15301.2001 "Animal and vegetable fats oils precipitate Determination centrifugation" (in English). For ease of use, the standard ISO 15301.2001 includes the following editorial changes. --- Deleted international standards foreword; --- The "this International Standard" by "this standard"; --- With a decimal point as a decimal point instead of the original ",". ","; --- The relevant formulas are numbered; --- With GB/T 15687 instead of the original International Standard ISO 661. The Standard Annexes A and B are informative appendices.

1 Scope

This standard specifies the method for crude precipitate a centrifugal separation and determination of the content. This standard applies to leaching or press Preparation of the precipitate in an amount ranging from 0.03mL/100g ~ 15mL crude/100g of. This method does not apply to 20 ℃ when not in liquid form lipid.

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 Be insoluble material was separated original oil available centrifugation tube after centrifugation substance collected at the bottom of the opaque layer. Note. the precipitate contains phospholipids, dirt, dust, etc., are dispersed in the aqueous phase, this standard can be used quantitatively. Dark insolubles layer top and white interior The precipitate is crystalline component part thereof. Principle 4 Uniformly mixing a predetermined sample was centrifuged, the precipitate is separated substances by centrifugation calibrated to measure the volume of the tube were Quantified.

5 Instruments

Conventional laboratory instruments, in particular the following equipment. 5.1 tube. 100mL, pear-shaped or conical, with stopper. Calcined glass. Figures 1 and 2. Note. Compared with pear-shaped pipe, the more difficult the opaque layer volume conical tube readout. 5.2 tube sets. used to hold tubes, resistant to oil erosion. 5.3 Centrifuge. with centrifuge tube (5.1) and centrifuge tube sleeve (5.2) supporting the use, can control the speed of centrifugation, the centrifuge tube so narrow portion Radial acceleration of free fall acceleration of 700 times to 800 times. See Appendix A centrifuge speed computing. No air conditioning in the laboratory should try to make the centrifuge maintained at a temperature in the range of 20 ℃ ~ 25 ℃. 5.4 Balance. a sense of the amount of 0.1g.
