Determination of Cyclopropenoid Fatty Acids in Ewe Milk Fat by GC-MS after Intravenous Administration of Sterculic Acid

Abstract: Cyclopropenoid fatty acids (CPEFA), found in oilseeds from Malvaceae and Sterculiaceae, have been shown to interfere with the endogenous synthesis of several bioactive lipids of dairy fat, such as cis-9, trans-11 18:2 and cis-9 18:1, by inhibiting Δ9-desaturase. No previous study has reported the presence of sterculic acid in animal fat and its incorporation in tissues after its administration, due to the lack of a proper methodology. In the present research, a GC-MS method based on cold base derivatiz… Show more

“…This would be further supported by the results shown before. 12,22 On the other hand, in contrast to those previous findings, CPFAs were also detected in cheese fat samples from ewes fed hay for the first time. Among these, only cheese samples from one commercial "hay" farm (H4) were negative to CPFAs (concentration under the LOD) (see Figure 1).…”

“…Segundo Lago et al (1987) foram analisadas características químicas e nutricionais de algumas sementes da Amazônia, sendo que o teor de proteínas para as sementes de Pachira aquatica foi de 15,1%. Barros et al (2020) O ácido estercúlico pode ser encontrado em grandes concentrações com até 78% no óleo das sementes de Sterculia foetida (LOLLI et al, 2020). Já o ácido malválico pode ser encontrado principalmente no óleo das sementes de algodão da espécie Gossypium.…”

“…Ambos os ácidos foram encontrados na raiz, folha, caule e tecido caloso em plantas de Malvaceae. Em plantas, o ácido estercúlico é mais comum do que o ácido malválico (LOLLI et al, 2020).…”
