“…The acidity index represents the amount of free fatty acids after triglyceride hydrolysis [36]. Actually, the acidity index the most important physicochemical index used to evaluate oil quality [9]. The acidity index of babassu oil (3.47 mg KOH/g) is lower than the value stipulated by Codex Alimentarius [22] (4 mg KOH/g) (Table 2) and higher than found by Serra et al [20] (1.06 mg KOH/g).…”

“…Iodine index measures the degree of oil unsaturation [9], i.e., the higher the iodine index, the greater the amount of unsaturated fatty acids and the higher the susceptibility to oxidation [7]. Iodine Index in babassu oil was 14.0 g iodine/100 g. The results reveal that babassu oil has a low degree of unsaturation and meets the requirements stipulated by Codex Alimentarius (10.0–18.0 g iodine/100 g) [22].…”

“…A critical indicator of the quality of edible oils is its oxidative stability, which is directly related to their shelf life [8,9,10]. Oxidative stability is influenced by the chemical composition of the oil and action of various factors with pro- and antioxidant characteristics, and it can occur during oil processing and storage [11].…”

Interest in edible oil extraction processes is growing interest because the final nutritional quality of the extracted oil depends on the procedure used to obtain ir. In this context, a domestic cold oil press machine is a valuable tool that avoids the use of chemicals during oil extraction, in an environmentally friendly way. Although babassu (Attalea speciosa) oil is economically important in several Brazilian regions due to its nutritional and healthy features, few studies have been conducted on the chemical composition and stability of babassu oils extracted by cold pressing. Babassu oil’s major constituents are saturated fatty acids (~86.42%), with the most prevalent fatty acids being lauric (~47.40%), myristic (15.64%), and oleic (~11.28%) acids, respectively, within the recommended range by Codex Alimentarius, presenting atherogenicity and thrombogenicity indexes favorable for human consumption. Peroxide value, Rancimat, and TGA/DSC results indicated that babassu oil is stable to oxidation. Also, macro- (Na, K, Ca, Mg, P) and micro-elements (Fe, Mn, Cr, Se, Al, and Zn) of babassu oil were determined, revealing levels below the tolerable upper intake level (ULs) for adults. These findings demonstrated that cold-press extraction using a domestic machine yielded a high-quality oil that kept oil chemical composition stable to oxidation with natural antioxidants.

“…To date, data for the rare species of A. quangensis were lacking [35]. Several studies focusing on the pharmacological effects of stem, bark, leaves or kernel oil were conducted, not taking element contents of the fruits into account [36,37]. Recently, fruits of A. quangensis were analyzed revealing raised contents of chromium (Cr) (0.4 mg/kg) and additional high contents of Al (713 mg/kg) [18].…”

Metal Accumulation Properties of Eight Traditionally Utilized Nutritional Plants and Their Potential as Suitable Crops for Cultivation on Acidic Soils of the Northern Province Uíge, Angola

et al. 2022

High metal contents of acidic soils from sub-Saharan Africa often prevent the cultivation of crops and lead to a low livestock yield. The carbohydrate rich diet of the Angolan population is low in minerals and vitamins, resulting in various deficiency syndromes and a high child mortality rate. Eight traditionally utilized plants (Anisophyllea quangensis, Annona stenophylla subsp. cuneata, Canarium schweinfurthii, Eugenia malangensis, Landolphia lanceolata, Raphionacme madiensis, Tristemma mauritianum, Vitex madiensis subsp. madiensis) with nutritional value for the Angolan population were analyzed for their soil and growing conditions. The species are adapted to the local conditions and can serve as crops for the unfavorable soils of the province Uíge. Chemical and physical characteristics of the uppermost soil (0–5 cm) and in 30 cm depth were analyzed. The plant-available macro-and micronutrients were determined using Mehlich 3 extraction. Data are completed with leaf tissue analyses, examining the uptake of minerals. As aluminum (Al) and manganese (Mn) are plant-available in high amounts, local plants evolved mechanisms dealing with those metals. These Al accumulators with foliar contents above 1000 mg/kg are Anisophyllea quangensis (7884 mg/kg), Landolphia lanceolata (6809 mg/kg), Tristemma mauritianum (4674 mg/kg), and Eugenia malangensis (13,989 mg/kg). All four species bear edible fruits with nutritional potential. The domestication and commercialization of those plants seem to be promising, utilizing local soils without expensive amelioration techniques.

“…Knowing that the oxidative stability of the oil is intimately linked according to several authors to its biochemical composition, in particular to its PUFA content and certain unsaponifiable secondary compounds such as tocopherols, carotenes, and/or phenols (Schroeder et al, 2006;Mansouri et al, 2016;Nkengurutse et al, 2019), we have tried to establish correlations between some of these compounds and the oxidative stability of our oils (Supplementary Table S1). The obtained results showed that the oxidative stability of the studied oils was positively correlated with the tocopherol content (r = 0.763; P < 0.001) and more particularly with the ctocopherol content (r = 0.754; P < 0.001).…”

This study aims to determine the chemical composition of hemp (Cannabis sativa L.) seeds of two varieties cultivated in four different regions of northern Morocco. The content of protein, insoluble fibre, ash, total phenols and flavonoids was found to be 19. 25%-24.18%, 26.40%-37.40%, 3.72%-5.39%, 134.57-199.90 mg 100g À1 and 39.40-69.54 mg 100g À1 respectively. Oil contents ranged from 26.42 to 35.19 g 100 g À1 of seeds in the four collection sites with variable oxidative stability at 100°C from 9.73 to 15.42 h. Total tocopherol content was between 376.46 and 796.06 mg kg À1 of oil, with a dominance of ctocopherol. Fatty acids consisted mainly of unsaturated fatty acids (87.30-88.96%) with a predominance of linoleic acid (48.26%-55.39%). Triacylglycerols (TAGs) composition analysis revealed the presence of 18 TAGs with an equivalent carbon number of 38-48. The composition of TAGs was predominated by LLL (14.34%-22.62%), OLL (12.77%-18.78%) and LLLn (12.32%-18.59%). Furthermore, the majority of the evaluated parameters were strongly influenced by the varietal factor, growing area and their interaction. The knowledge of this composition variability in seeds of non-industrial Cannabis sativa varieties cultivated in northern Morocco could be useful in new Cannabis variety breeding programmes potentially valuable as non-conventional oil in cosmetic and agro-industry.
