“…The fatty acid analysis was carried out using the internal standard method (Nasopoulou et al 2011). A five-point calibration curve was prepared using five solutions of heptadecanoic Shimadzu CLASS-VP (GC-17A) (Kyoto, Japan) gas chromatograph equipped with a split/splitless injector and flame ionization detector.…”

Given that goat milk and dairy products should be consumed daily according to suggestions based on Mediterranean diet, the current study evaluates the antiatherogenic properties of goat milk and goat dairy products (yogurt and white cheese). Total lipids (TLs) of all three samples were extracted by the method of Bligh and Dyer and further separated into total polar lipids (TPLs) and total neutral lipids (TNLs) by counter current distribution. The fatty acid profiles of TPL and TNL of all three samples were determined by gas chromatography analysis. TL and TPL were tested to determine whether they induce platelet aggregation or inhibit platelet aggregation induced by the platelet-activating factor (PAF). The most active lipids were found in goat white cheese (i.e., since they showed lower IC 50 values in both TL and TPL samples than corresponding fractions of goat milk and goat yogurt), so the TPL of goat white cheese were further separated by preparative thin-layer chromatography (TLC). The obtained polar lipid fractions after TLC separation were also tested for their biological activity. All the samples' lipids, and especially the polar ones, were found to exhibit strong anti-atherogenic activities. This fact highlights the nutritional value of goat dairy products in terms of cardioprotection, as PAF is a crucial inflammatory mediator that is implicated in the mechanism of atherogenesis.

“…While other study indicated that the total lipids of gilthead sea bream nourished with olive pomace diet limited statistically reduced concentrations of fatty acids, whereas presented the strongest biological activity against platelet aggregation induced by Platelet Activating Factor. These information designate that olive pomace is used as a fractional additional of fish oil in fish feedstuff serving its cardio protective wealth [Nasopoulou et al, 2011].…”

“…Because of the gradually increase of global population , researches on the waste-management issues of OP has been vigorous over the last decade, as results in higher food consumption and increased demand for processed food, meat, dairy and fish [Charles, et al, 2010]. Previous studies show that OP can be used as additional constituent of fish oil in fish nourish improving its cardio protective possessions [Nasopoulou et al, 2011]. The use of OP in agriculture and aquaculture carries improvements at different heights and these must be assessed in terms of water-efficiency, enhanced nutritional value of the last animal and fish foods and last food and also maintainable production of animal and fish foods [Nasopoulou et al, 2011 ;Nasopoulou and Zabetakis, 2013].…”

At the same time the biggest challenge for food industries and scientists is to develop environmentally maintainable processes of food production reinsuring food security and suppressing environmental pollution.…”

Abstract:In this study, the olive pomace was considered because of its importance in the environment. So, this study carried out to estimate the total nitrogen content and the fatty acids profile of olive pomace. The olive pomace samples were collected from Irbid, Jarash, Ajloun and Mafraq during the harvesting season 2014 to study the biochemical characteristics of fatty acid composition and the total nitrogen (TN) content. The total nitrogen content was determined by standard Kjeldahl method and the fatty acid profile was detected by gas chromatography (GC). The results show that the total nitrogen content ranged from (0.39 ± 0.0) to (0.62 ± 0.02) with statistically significant difference suggesting that the composition of matrices and their percentage may be responsible for composition of amendments. The calculated total protein percentage ranged between (2.43 ± 0.00) to (3.87 ± 0.17). Also, 13 different fatty acids were quantitatively profiled and quantitated. Oleic acid (C 18:1) was found to be the highest percentage of all other fatty acids and ranged between (59.03%) and (63.81%), moreover the C 18:1/C 18:2 (oil quality) was calculated and C.V% showed variation meaning that nutritional implication could affect the oxidative stability of oils. In conclusion, OP by-product could give a sustainable and alternative-cheap source for fertilizers, pharmaceutical industries, cosmetics and other industries.

“…OP has also been reported as a partial replacement of fish oil (FO) in gilthead sea bream (Sparus aurata) where it was found that feeding of OP to fish results in an improvement in its ability to prevent atherogenesis and therefore heart diseases (Nasopoulou et al, 2011). The growth performance factors of gilthead sea bream fed with FO diet in comparison with gilthead sea bream fed with OP exhibited no statistical differences regarding feed conversion ratios and specific growth rates.…”

Olive Pomace (OP) is the main agricultural by-product of olive industry; because of its nature, it is a major environmental issue for all the olive-producing countries. Research on the waste-management issues of OP has been active over the last decade. The data presented in the present review suggest that OP could be exploited as an alternative dietary lipid source in compounded fish feeds resulting in the formulation of functional fish feeds and aquacultured fish according to the EU legislation (EC 1924(EC /2006. Moreover OP can also be used in agriculture by inclusion in animal feeds without attenuating animal performance and meat quality.In this review, all the latest results on the in vitro and in vivo studies regarding the usage of OP in fish and animal feeds are evaluated and the environmental and nutritional implications for aquaculture and agriculture industries are presented.
