“…Regarding re-esterified oils, although no statistically significant differences were found among palm oil treatments, PEH showed the greatest total FA apparent absorption. This could be due to the emulsifying effect of MAG and DAG molecules (Martin et al, 2014). However, PEH oil was mainly composed of 1(3)-MAG and 1,3-DAG species, which, in terms of fat absorption, are not expected to be as well absorbed as 2-MAG and 1(3),2-DAG, because pancreatic lipase specifically hydrolyzes the external sn-1,3 positions (Mattson and Beck, 1956).…”

“…On the other hand, these re-esterified oils may also have different proportions of mono-(MAG) and diacylglycerols (DAG) (Vilarrasa et al, 2014). These amphiphilic molecules can act as emulsifying agents, able to enhance lipase activity and FA incorporation into mixed micelles (Martin et al, 2014). It was hypothesized that the different acylglycerol structure of re-esterified oils may enhance the SFA apparent absorption and, thus, their overall nutritive value, especially in young animals.…”

Re-esterified oils are new fat sources obtained from chemical esterification of acid oils with glycerol (both economically interesting by-products from oil refining and biodiesel industries, respectively). The different fatty acid (FA) positional distribution and acylglycerol composition of re-esterified oils may enhance the apparent absorption of saturated fatty acids (SFA) and, thus, their overall nutritive value. The aim of the present study was to investigate the potential use of re-esterified palm oils, in comparison with their corresponding acid and native oils, and also with an unsaturated fat source in weaning-piglet diets. The parameters assessed were: FA apparent absorption, acylglycerol and free fatty acid (FFA) composition of feces, and growth performance. One-hundred and twenty weaning piglets (average weight of 8.50 ± 1.778 kg) were blocked by initial BW (six blocks) and randomly assigned to five dietary treatments, resulting in four piglets per pen and six replicates per treatment. Dietary treatments were a basal diet supplemented with 10% (as-fed basis) of native soybean oil (SN), native palm oil (PN), acid palm oil (PA), re-esterified palm oil low in mono-(MAG) and diacylglycerols (DAG) (PEL), or re-esterified palm oil high in MAG and DAG (PEH). Results from the digestibility balance showed that SN reached the greatest total FA apparent absorption, and statistically different from PN, PA and PEL ( P < 0.05). There were no statistical differences among palm-oil sources ( P > 0.05), but PEH achieved the greatest total FA apparent absorption. Animals fed PEL, despite the fact that PEL oil contained more sn-2 SFA, did not show an improved absorption of SFA ( P > 0.05). Animals fed PA and PN showed similar apparent absorption coefficients ( P > 0.05), despite the high FFA content of PA oil. The acylglycerol and FFA composition of feces was mainly composed of FFA. There were no significant differences in growth performance ( P > 0.05). Results of the present study suggest that, despite the different acylglycerol structure of re-esterified oils, there were no significant differences in digestibility or performance with respect to their corresponding PN and PA oils in weaning-piglet diets.

Fatty acid digestibility in gilthead sea bream fed diets containing native, re-esterified or acid vegetable oils

et al. 2016

Re‐esterified vegetable oils are obtained from a chemical esterification reaction between vegetable acid oils and glycerol. Due to their properties, it is expected that they have a higher nutritive value than their corresponding acid oils and a better digestibility than their native counterparts. The aim of this study was to determine the effect of re‐esterified oils with a different monoacylglycerol (MAG) and diacylglycerol (DAG) content, produced from palm or rapeseed, on fatty acid digestibility in gilthead sea bream (Sparus aurata). Triplicate groups of fish were fed nine experimental diets containing different oils during 28 days. For each source, four different types of oil were used: native, re‐esterified low or high in MAG and DAG and acid. A commercial fish oil was used for the control diet. Diets containing re‐esterified oils had better apparent digestibility coefficients (ADC) of total fatty acids than acid oil diets. Re‐esterified oils do not negatively affect apparent digestibility coefficients of fatty acids when compared to their corresponding native oils and could be incorporated as a source of energy in diets for gilthead sea bream. An improvement in digestibility compared to the native oil diet was only obtained in palm re‐esterified oil high in MAG and DAG.

“…These oils can have a high final content of partial acyglycerols (monoacylglyerols, MAG and diacylglyerols, DAG), amphiphilic molecules that could exert a beneficial effect on digestibility (Fregolente et al, 2009;Martin et al, 2014). Good results in fat absorption and growth performance in broiler chicks and chickens have been obtained when including re-esterified VO in diets (Vilarrasa et al, 2014(Vilarrasa et al, , 2015.…”

Acid and re-esterified rapeseed oils as alternative vegetable oils for rainbow trout diets: Effects on lipid digestibility and growth

et al. 2016

The present study aimed at evaluating the effects of dietary acid and re-esterified rapeseed oils as alternatives to native vegetable oils (VO) on growth performance and feed utilization in rainbow trout. Acid oils are a free fatty acid (FFA)-rich by-product from the refining of VO and re-esterified oils are the final product of a chemical esterification process between acid oils and glycerol. Because re-esterified oils have a high content of mono-and diacylglycerols (MAG and DAG), known for being good emulsifiers, a higher nutritive value than that of the native and the acid oils might be expected. A 72-day feeding trial where triplicate groups of rainbow trout were fed eight experimental diets formulated to contain 15% of a native, a re-esterified and an acid rapeseed oil, in addition to a 5% of fish oil (FO), was carried out. Diets with the native or the re-esterified oils blended with the acid oil were also studied. A commercial fish oil was used for the control diet. Fish fed rapeseed acid and re-esterified oil diets (RA and RE, respectively) showed high fat and total fatty acid apparent digestibility coefficients (ADC) (RA: 90.5 ± 0.3%, RE: 92.5 ± 1.0% for total fat and RA: 95.7 ± 0.1%, RE: 95.8 ± 0.2% for total fatty acids). However, the lowest total fatty acid ADC was that obtained in animals fed RA, which was significantly lower (P b 0.05) than that of fish fed the rapeseed native oil diet (RN: 96.7 ± 0.1%). No significant differences in final weight were obtained between fish fed RA (375.9 ± 2.9 g) and RE (381.5 ± 11.1 g) and those fed RN (393.7 ± 6.1 g), even though both values were significantly lower (P b 0.05) than that of fish fed the control diet (411.1 ± 3.3 g). Nonetheless, fish fed diets including blends of the rapeseed acid and the re-esterified oils (RE/RA and RA/RE) had higher final weights (392.8 ± 4.4 and 394.6 ± 1.6, respectively) than those of RA and RE, although differences were not statistically significant. Furthermore, RA and RE diets did not produce relevant changes in plasma parameters or in the morphology of liver and intestine of fish. Therefore, the inclusion of rapeseed acid and re-esterified oils along with a 5% of FO in aqua feeds does not seem to have negative effects on fat and fatty acid digestibility, growth, plasma parameter or morphology of liver and intestine in rainbow trout. However, before recommending their use, further studies regarding their effects on the final composition and quality of fillets should be carried out. Statement of relevance: Re-esterified and acid rapeseed oils could be included in diets for rainbow trout as economically advantageous sources with no negative results in fat and fatty acid digestibility, plasma parameters and morphology of liver and intestine.
