“…The iodine index is a measure of the unsaturation of fats and oils and consequentially the susceptibility to oxidation [ 29 ]. The obtained iodine index (76.7 I 2 /100 −1 g) is close to values found in analyses of 10 oils of different cultivars of olive ( Olea europaea L.), between 80 and 89 I 2 /100 −1 g [ 30 ]. Its counterpart, the oil of the fruit of Byrsonima cydoniifolia A.…”

The fruit of Caryocar brasiliense Cambess. is a source of oil with active compounds that are protective to the organism. In our work, we analyzed the physicochemical characteristics and evaluated the effects of supplementation with C. brasiliense oil in an animal model. We characterized the oil by indices of quality and identity, optical techniques of absorption spectroscopy in the UV–Vis region and fluorescence, and thermogravimetry/derived thermogravimetry (TG/DTG). For the animal experiment, we utilized mice (Mus musculus) supplemented with lipidic source in different dosages. The results demonstrated that C. brasiliense oil is an alternative source for human consumption and presents excellent oxidative stability. Primarily, it exhibited oleic MFA (53.56%) and palmitic SFA (37.78%). The oil level of tocopherols and tocotrienols was superior to the carotenoids. The supplementation with C. brasiliense oil reduced the levels of total cholesterol, LDL-c, and non-HDL-c. Regarding visceral fats and adiposity index, the treatment synergically supplemented with olive oil and C. brasiliense oil (OO + CO) obtained the best result. Therefore, C. brasiliense oil is a high quality product for consumption. Its supplementation promotes beneficial effects mainly on the lipidic profile.

“…A higher acid value and peroxide value of an oil is an indicator of the generation of impurities in the oil. The presence of impurities in the oil increases its relative density [24], refractive index [25] and also affects its absorbance at 270 nm (A 270 ) [26] because these impurities increase the atomic numbers of the constituent atoms in the oil. The results provided in the Table 1 revealed that the values of the relative density, refractive index, and A 270 of the sample oils and the reference oil complied with their standard values.…”

Background: The quality of medicinal/food products is directly related to the consumer’s safety. Virgin Olive Oil (VOO) is a widely used oil in Saudi Arabia for cooking, frying, and salad dressing. It is also an ingredient of many pharmaceutical products. Therefore, its regular quality assessment is essential for the consumer’s safety. Objective: To assess standard quality parameters of the marketed VOO brands in the Rafha City of Saudi Arabia and to perform their antioxidant activity evaluation. Methodology: The different brands of VOO sold in the Rafha City of Saudi Arabia were collected from two supermarkets and one local shop. The quality of the different brands of the VOO was assessed for their physical appearance, solubility, relative density, refractive index, absorbance, acid value, and peroxide value. The standard procedures provided in the British Pharmacopeia (BP) were used to assess these parameters. The antioxidant activity of the oils was performed by the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) method. Results: The VOO sample test results revealed no significant change in the studied parameter's standard values. The VOO samples presented compliance with the specification of VOO provided in the BP. The VOOs were also free of Sesame oil, which is one of the possible adulterants of the VOO. The antioxidant activity data of the VOO samples (IC50 = 107 to 110 mg oil) also matched with antioxidant activity data of the reference VOO (IC50 = 105 mg oil). The antimicrobial activity of the VOO samples and the reference VOO was also comparable. Conclusion: The different brands of the marketed VOO comply with the specification of VOO provided in the BP. They were suitable for their intended use/application.

“…Ultrasonic-assisted extraction, ionic liquid extraction, microwave-assisted extraction and supercritical fluid extraction require relatively less solvent, and they can separate phenolic compounds efficiently with good reproducibility. The characteristics of low extraction temperature and time-saving are also more suitable for industrial production Morgan, 2013;Shirzad et al, 2017).…”

Ficus carica L. (FC) is rich in phenolic compounds such as phenolic acids, flavonoids, and anthocyanins. Phenolic compounds in FC show remarkable health benefits and applications. The composition of phenolic compounds in FC can vary with some factors, such as variety, ripeness, geographical location, extraction methods and processing methods. New techniques such as supercritical fluid extraction, subcritical water extraction and ionic liquid extraction should be further developed and combined with traditional techniques to obtain higher quality sources of phenolic compounds. Numerous in vivo and in vitro studies reported healthy benefits of phenolic compounds in FC, such as anti‐oxidant, anti‐inflammatory, anti‐diabetic, anti‐obesity, anti‐cancer and anti‐Alzheimer's. Further works are required to reveal mechanisms and structure‐activity relationships, such as targeted metabolomics and pharmacological studies. In terms of applications, phenolic compounds in FC as prebiotics on the intestinal flora need to be further studied to expand their applicability in food fermentation. In a word, this review highlights the remarkable health benefits and application value of phenolic compounds in FC.
