Gestation and the neonatal period are crucial periods in infant development. Many components of breast milk, including fatty acids, play an important role in strengthening the immune system. The aim of our research was to evaluate the fatty acid profiles of milk from 69 mothers, including subjects having a normal weight, obesity, or gestational diabetes. For the analyses, we used gas chromatography (GC) with flame ionization detection (FID) and GC coupled with mass spectrometry (GC/MS). The main fatty acids found in breast milk were palmitic acid (C16:0; 26–28%), linoleic acid (C18:2; 23–28%), and α-linolenic acid linoleic acid (C18:3; 15–17%), followed by myristic acid (C14:0; 5–8%), lauric acid (C12:0; 4–6%) and stearic acid (C18:0; 4–5%). The average breakdown of fatty acids was 50% saturated, 44% polyunsaturated, and 6% monounsaturated. Breast milk samples were classified using principal component analysis and linear discriminant analysis. Results showed that milk from the two major groups of obese and normal body mass index (BMI) could be distinguished with an accuracy of 89.66%. Breast milk samples of Hungarian and Ukrainian mothers showed significant differences based on the fatty acid composition, which variations are attributable to the mothers’ dietary habits.

“…Trans fatty acids have been detected in breast milk, primarily vaccenic acid (C18:1 n-7), and elaidic acid (C18:1 n-9), which are associated with the consumption of milk and dairy products [ 35 ]. Trans fatty acid intake in lactating women usually depends on their geographical location and socio-economic situation.…”

“…The average TFA from the industrial process in the COL, TM and MM samples were 0.11%, 0.08% and 0.12%, respectively. Study carried out by Aumeistere et al (2021) in European women also observed levels of 0.10% of these FAs in BM, considered low values. This percentage found in our study may have occurred because the study participant received nutritional guidance while attending the nutrition/prenatal outpatient clinic and did not consume large amounts of industrialized foods such as margarine, vegetable creams, cookies, chips, ice cream, pastries, which are sources of TFA, according to the report during the consultation.…”

The purpose of this case study was to investigate polyunsaturated fatty acids in colostrum, transitional milk and mature milk of a nursing mother attended to Roux-en-Y gastric bypass two months prior to pregnancy. For this, was collected 2ml (colostrum), 4ml (transitional milk) and 4ml (mature milk) samples obtained by manual expression of the breast that was not sucked in the last feeding, in the morning and placed in Eppendorfs-type microtubes. The fatty acid composition was performed by means of gas chromatography. The mean proportions of fat in colostrum, transition milk and mature milk were: eicosapentaenoic acid: 0.06%; 0.05% and 0.06%; docosahexaenoic acid: 0.12%, 0.08% and 0.09%; arachidonic acid: 0.58%, 0.37% and 0.42%, respectively; trans fatty from the industrial process: 0.11%, 0.08% and 0.12% and trans fatty from ruminant sources (0.09%, 0.10% and 0.12%, respectively. The relevance of this case study lies in the fact that it shares knowledge about on the fatty acid composition of breast milk from a nursing mother post Roux-en-Y gastric bypass. The mean linoleic acid and alpha-linolenic acid found in the mature milk was below the means found in studies carried out in Brazil from eutrophic women who did not underwent bariatric surgery. In this study, trans fatty acids were found in maternal milk but considered low values. As a relevant recommendation for future work, it is suggested that research be carried out with a larger population undergoing such a procedure to investigate the composition of polyunsaturated fatty acids in breast milk.

“…Additionally, stearic acid was observed only in S 13 , S 14 , and S 15 at concentrations of 0.16, 0.66, and 0.37, respectively. Vaccenic acid is a natural trans-fatty acid thatis considered the main trans-fatty acid present in human milk [34]. Vaccinic acid (C18:1) was found in low amounts in the oils of the jojoba seeds of the various elite lines, ranging from 0.72 to 1.62%.…”

Evaluation of the Effect of Elite Jojoba Lines on the Chemical Properties of their Seed Oil

Jojoba oil (JO) extracted from seeds has outstanding properties, including anti-inflammatory, antioxidant, and antibacterial activities, and can be stored forlong periodsof time. The unique properties of jojoba oil depend on its chemical composition; therefore, the effect of the jojoba genotype on the chemical properties and active components of the seed oil was evaluated in this study. Oil samples were collected from 15 elite Egyptian jojoba lines. The chemical composition, such as moisture, crude fiber, crude oil, ash, and crude protein of elite lines’ seeds was determined to investigate the variation among them based on the jojoba genotype. In addition, the iodine value was obtained to measure the degree of jojoba oil unsaturation, whereas the peroxide number was determined as an indicator of the damage level in jojoba oil. Fatty acid composition was studied to compare elite jojoba lines. Fatty acid profiles varied significantly depending on the jojoba genotype. Gadoleic acid exhibited the highest percentage value (67.85–75.50%) in the extracted jojoba oil, followed by erucic acid (12.60–14.81%) and oleic acid (7.86–10.99%). The iodine value, peroxide number, and fatty acid composition of the tested elite jojoba lines were compared withthose reported by the International Jojoba Export Council (IJEC). The results showed that the chemical properties of jojoba oils varied significantly, depending on the jojoba genotype.
