“…Studies in broilers [46] and post-weaning piglets [47] showed that dietary combinations of Vit E with different polyphenol sources did not improve animal performance compared to control diets or diets supplemented with only one antioxidant. Even though a synergistic antioxidant effect between secondary plant compounds and tocopherols has been proposed [48], our study could not support this hypothesis in finishing pigs. That effect might probably be verified in animals subjected to stressful situations, such as weaning.…”

This study aimed to assess the impact on growth, economic results, apparent nutrient digestibility (CTTAD), physiological variables, and animal behaviour when 214 fattening pigs (78 ± 8.5 kg of initial body weight and 130 ± 4.5 days of age) of both sexes (gilts and boars) were fed two levels of carob pulp (Cp, 0 vs. 20%) and two doses of vitamin E (Vit E, 30 vs. 300 IU/kg) for 40 days. No interaction effects between factors studied (Cp, Vit E, and sex) were observed on the variables. Most productive traits were unaffected by Cp or Vit E inclusion. However, the Cp increased the feed conversion ratio during the first 20 days. The Cp group showed a higher CTTAD of ether extract and hemicellulose but lower CTTAD of crude protein. Pigs fed Cp had a lower plasmatic urea content than the control group. The high Vit E doses increased the CTTAD of every nutrient and the plasmatic α-tocopherol content. The pigs fed Cp tended to spend more time eating in the early morning, likely to mitigate tannins’ astringent effects. Dietary inclusion of 20% Cp in finishing high-conformation pigs is possible without affecting overall performance though it reduces nutrient CTTAD and increases feeding cost. Supra-nutritional doses of Vit E do not affect pig performance but increase the α-tocopherol deposition with potential antioxidant effects.

There is a growing interest in using by-products rich in polyphenols, such as carob pulp (Cp, Ceratonia siliqua L.), as a dietary source of antioxidants for animals. This study assesses the effects of including Cp in lambs’ diet and meat display time (0, 7, 9, and 11 days) in modified atmosphere packaging on meat colour, fatty acid (FA) composition, tocopherol levels, and lipid oxidation values in the Semimembranosus muscle of 40 light lambs. The lambs were fed with concentrates supplemented with increasing Cp levels (0, 150, and 300 g/kg) for 45 days before slaughter. Metmyoglobin (MMb) and malondialdehyde (MDA) contents increased linearly with display time (p < 0.05), regardless of diet (p > 0.05). At 11 days of display, MMb (28 ± 0.8%) and MDA (0.6 ± 0.1 mg MDA/kg of meat) contents remained within the acceptable limits. The α-tocopherol content was lower in the 30% Cp group and meat (p < 0.05). Total saturated and monounsaturated FA contents (934 ± 64 and 823 ± 65 mg/100 g of meat, respectively) did not differ significantly among the groups. However, the meat from lambs fed with 30% Cp showed reduced levels of branched-chain FAs, while polyunsaturated FAs increased (p < 0.05) compared to the control lambs. The inclusion of Cp in the lamb’s diet, up to 30%, did not lead to meat deterioration and improved certain quality parameters, including a healthier FA profile. These findings highlight Cp’s potential as an alternative antioxidant source in animal diets.

“…They display important antioxidant activities in the protection of lipids from peroxidation by scavenging peroxy radicals of polyunsaturated fatty acids or by reacting with singlet oxygen and other reactive oxygen species. [12,13] This crucial activity makes them important components in cardiovascular disease [14,15] and cancer prevention. [16,17] Tocopherols are naturally found in several matrices and foods.…”

Coffee grounds are the most commonly generated daily waste in the world, raising numerous questions regarding their proper management and their environmental impact. The present study focuses on the physical and chemical characterization of oil extracted from spent coffee grounds (SCG), with the aim of valorizing this by‐product as a potential source for oil production. The results obtained from the analysis of SCG oil were also compared to those of some edible oils (soybean, corn, and sunflower oils) and cosmetic oils (lentisc, sweet almond, and castor oils). The results revealed that spent coffee waste yielded an important amount of oil, specifically 17.19%, as compared to corn (4.31%) and soybean (19.52%) seeds. Regarding the fatty acids composition of SCG oil, eight components were identified, with a high percentage of polyunsaturated fatty acids accounting for more than 45% of total fatty acids. The phytosterols composition of SCG oil revealed the presence of seven components, with β‐sitosterol being the predominant one. The tocopherol analysis showed that SCG oil contained only α and β isomers, with β‐tocopherol being the dominant form at over 68%. These findings accentuate the potential of spent coffee waste as a promising alternative for oil production and open up new applications for SCG oil, such as in the food industry, pharmaceutical applications, and cosmetics.Practical Application: Given the significant increase in the demand for vegetable oils, the oil industry has recently begun to explore new plant matrices, particularly those having low costs. SCG are the most commonly generated daily by‐product in the world. The present investigation aims to characterize and valorize the oil extracted from SCG. The obtained results revealed the potential of SCG as a promising alternative for oil production. Consequently, valorizing spent coffee waste as a natural by‐product for oil production can be an ideal solution to address numerous issues related to its proper management and its environmental impact. Hence, the oil industry can promote spent coffee waste, cheapest by‐products, as a promising alternative for oil production. Moreover, the present investigation represents a commendable model of the circular economy since the remaining waste obtained after extracting lipids from the coffee grounds waste can be used as natural fertilizer rich in protein for plant development.
