  2. Total saturated fatty acids (SFAs) = the sum of C8 to C20.
  3. Total mono unsaturated fatty acids (MUFAs) = the amount of C18:1.
  4. Total poly unsaturated fatty acids (PUFAs) = the sum of C18:2 and C18:3.
  5. Data are expressed as values: mean ± SE and analysed by one-way analysis of variance.
