Phenol Content

The use of deficit irrigation techniques on olive orchards is the main trend aiming to optimize water savings while improving functional and sensory characteristics of oils from trees under deficit irrigation techniques. The brand hydroSOStainable has been defined for crops produced under water restriction conditions. HydroSOStainable olive oils obtained under two new regulated deficit irrigation and one sustained deficit irrigation treatments in “Arbequina” olive trees were evaluated by analyzing quality parameters, antioxidant activity, total phenol content, fatty acid profile, volatile compounds, and sensory descriptors. Results showed that some of these irrigation strategies improved the phenol content at “moderate” stress levels, slightly enriched the fatty acid profile (~3.5% increased oleic acid and simultaneously decreased saturated fatty acids), and increased some key volatile compounds and also several key sensory attributes. Therefore, hydroSOStainable olive oil may be more attractive to consumers as it is environmentally friendly, has a higher content of several bioactive compounds, and has improved sensory characteristics as compared to control (fully irrigated) oils.

The objective of this study was to evaluate the effects of supplementation of dairy cows with different fatty acid sources (soybean oil (SO) and fish oil (FO)) on milk production, milk composition, milk fatty acid profile, and physicochemical and sensory characteristics of ice cream. During 63 days, fifteen Holstein cows averaging 198 ± 35 days in milk were assigned to three groups: control diet with no added lipid (n = 5 cows); and supplemented diets with SO (n = 5 cows; unrefined SO; 30 g/kg DM) or FO (n = 5 cows; FO from unrefined salmon oil; 30 g/kg DM). Milk production, milk fat, and milk protein were not affected by treatments. Saturated fatty acids in milk fat were decreased with SO and FO compared with control. C18:2 cis-9, cis-12 was increased with SO whereas C18:2 cis-9, trans-11, C20:3n-3, C20:3n-6, C20:5n-3, and C22:6n-3 were the highest with FO. Draw temperature and firmness were higher in SO compared to control and FO ice creams. Melting resistance was higher in FO compared with control and SO ice creams. Supplementation of cow diets with SO and FO did not have detrimental effects on milk production, or ice cream physicochemical and sensory characteristics.

PurposeTo meet the consumer demand for a healthier diet, this study emphasizes the feasibility of using vegetable oil gelled emulsions in low-fat industrialized burgers with high contents of polyunsaturated fatty acids (PUFAS). Commercial canola and olive oils have been tested as a relatively inexpensive source of PUFAS.Design/methodology/approachBeef burgers were reformulated by replacing (0, 25, 50, 75 and 100%) pork back-fat with two carrageenan gelled emulsions of vegetable oils (canola and olive oil). The technological characteristics, sensorial properties and the fatty acid profile of reformulated burgers were evaluated.FindingsMoisture content and cooking loss increased and fat and protein contents reduced with higher replacements. Oxidative stability was not affected and replacements of up to 75% did not affect the burger's acceptance. A total fat content reduction of 40% was achieved in burgers with 100% back-fat replacement, improving its nutrient value by increasing the ω−6/ω−3 ratio and decreasing the saturated fatty acids content (in 47%) and the atherogenic (from 0.61 to 0.22) and thrombogenic (from 1.29 to 0.65) indexes. Replacing up to 75% with canola oil gelled emulsion is a promising approach in the design of healthier industrial low-fat burgers.Originality/valueDue to the association of some diseases with the consumption of products rich in saturated fat, the industry looks for alternatives not only to reduce the fat content but also to modify the fatty acid profile in meat products. This study further confirms the possibility of using carrageenan gelled fat replacer in industrialized burgers formulated with meat and other ingredients/additives commonly used to provide economic benefit. Also, confirms the feasibility to use commercial vegetable oils with relatively cheap cost than ω−3 rich oils as the oil phase in the gelled emulsion.

Aberdeen Angus (AA), Charolais (CH), Simmental (SI), and Hereford (HE) bulls were used in two fattening experiments with the objective of determining breed differences in chemical composition, sensory characteristics, and fatty acid profile of m. longissimus thoracis et lumborum. The target slaughter live weights were set at 550 kg for earlier maturing breeds AA and HE and 630 kg for later maturing breeds CH and SI. Intramuscular lipid contents were higher in AA and HE (P < 0.05) than in CH and SI, but cholesterol contents were similar among the breed groups. The highest content of dry matter was found in HE (P < 0.05), while AA had the lowest protein content (P < 0.001). Meat from AA generally received the highest scores for different sensory characteristics (odour, flavour, texture, and juiciness). Concentrations of stearic acid (C18:0) in total muscle lipids were lower in SI than in CH (P < 0.05), while total saturated fatty acids were lower in SI compared to CH (P < 0.001) and AA (P < 0.05). CH had less oleic acid (C18:1-n9c) and total monounsaturated fatty acids than AA (P < 0.05), SI and HE (P < 0.01). Concentrations of linolenic acid (C18:3-n3) were highest in AA (P < 0.01).

Olive Oils

This work aims at evidencing the quality and chemical composition of extra virgin olive oils according to stages of maturity and in relation to the geographical location of olives. Three different olive cultivars (Moroccan Picholine, Languedoc Picholine, and Frantoio), grown in two different locations in Morocco (Errachidia and Marrakech), were studied during the two crop years (2016 and 2017) at three stages of maturity (green, purple, and black). This work has been carried out by analyzing several parameters, such as the quality characteristics (acidity and peroxide value), the chemical composition (total phenol content and fatty acid composition) of the oils, and also the fruit characteristics of the olives (maturity index, fruit water content, and oil content). The results obtained in this study indicate that as maturity advanced, there was a slight rise in oil content and acidity, while there was a decrease in fruit water content and peroxide value in both locations during the two crop years. The fatty acid composition of extra virgin olive oil showed a significant increase of linoleic acid and polyunsaturated fatty acids (PUFAs) and a decrease of oleic acid, palmitic acid, monounsaturated fatty acids (MUFAs), and MUFA/PUFA ratio as the maturation process progressed. A significant gradual decrease was noted in total phenol content and bitterness intensity from the green stage to the black. Moreover, olive oil composition differed clearly between the two sites. Therefore, the olive cultivar, harvesting date, and geographic location influence the olive oil characteristics.

Application of cooking oil during thermal processing can influence the nutritional qualities of meat products during consumption. This study determined the effect of frying with sunflower and olive oil on the fatty acid profile of sausage fortified with edible meat waste (EMW) as a fat replacer was evaluated. Fresh beef sausages were formulated in ratios of 30% lean meat (LM) and 70% EMW, 50% LM and 50% EMW, and 90% LM and 10% fat (control) and designated as T1, T2, and T3, respectively. The proximate analysis results revealed significant differences ( P < 0.05 ) in fat, fat free dry matter (FFDM), and moisture contents across the treatment. Fresh beef sausage fortified with 70% EMW had the highest fat contents ( 25.7 ± 0.83 % ) while those fortified with 10% fat (T3) had the highest FFDM ( 55.85 ± 0.57 % ) and moisture content ( 69.15 ± 0.62 ) compared to other treatments. In addition, among individual saturated fatty acids, beef sausage fortified with 50% meat wastes (T1) revealed significantly higher palmitic acid ( 31.06 ± 0.13 ), stearic acid ( 22.52 ± 0.29 ), myristic acid ( 3.84 ± 0.05 ), and lauric acid ( 0.04 ± 0.05 ) and the lowest margaric ( 0.98 ± 0.02 ) contents as compared to treatments T2 and T3. Also, beef sausage containing 10% fat showed the lowest ( P < 0.05 ) saturated fatty acid (SFA) and higher monounsaturated (MUFA), polyunsaturated fatty acid (PUFA), n-6, n-3, PUFA : SFA, PUFA/MUFA, n-6/n-3, and desaturase indexes (DI) compared to treatments T1 and T2. Frying with sunflower oil significantly increased PUFA, n-6, n-6/n-3, and desaturase indexes and lowered SFA, n-3, and PUFA/SFA compared to frying with olive oil. In relation to raw beef sausage, frying with oil substantially increased the amount of MUFA, PUFA, n-6, and PUFA/SFA but reduced SFA content across the treatments.

The aim of this research was to determine fatty acid profiles in piglet brain, skin, and muscle, and in the milk of sows fed fat with different saturation grades during gestation and lactation. At 42 days of gestation, 50 multiparous sows were randomly allocated to one of two treatments, namely a diet containing pork lard (n = 25) and a diet containing soybean oil (n = 25). The fats were provided at 3.6% during gestation and at 4% during lactation. The experimental diets were offered through the weaning of the piglets. The fatty acid profile of the milk was determined fourteen days after parturition. At weaning (21 days postpartum) and seven days later, one of the piglets (n = 64) from 16 sows allocated to each treatment was selected at random to determine fatty acid profiles in brain, skin and muscle. Saturated and monounsaturated fatty acids were higher in the diet with pork lard than in that with soybean oil, in which the polyunsaturated fat content was higher. A higher saturation of fatty acids was found in milk from the sows that consumed pork lard, which contained more saturated fatty acids than the milk from sows that consumed soybean oil. The fatty acid profiles in muscle and skin of the piglets were affected by the diet of the sows. However, the fatty acid profile of the piglets’ brains was not affected by the diet of their mothers.
