“…This value showed a very positive result as it decreased between MO0 and MO50 samples. Considering that in sunflower oil the corresponding COX value is close to six [ 22 ], 20% lower than the TM samples of our study, it is proved that they possess better oxidative stability, and thus, have a longer shelf life.…”

“…The defatting procedure was repeated three times on the solid residue. The procedure for the detection of fatty acids and their abundance in T. molitor larval samples was followed according to Athanasiadis et al [ 22 ]. More specifically, fatty acid methyl esters were prepared by reaction of the oil (200 μL) with a small amount of sodium methoxide in methanol at room temperature.…”

Nowadays, more and more research is being carried out on various feeds of Tenebrio molitor larvae, in order to increase their nutritional value and render them a valuable component of the human diet. In this study, Moringa oleifera leaves were used in different proportions (up to 50%) to substitute wheat bran (the usually employed feed), in order to evaluate their effect on the growth and development of the larvae, as well as on their composition in crude protein, fat and fatty acids, ash, vitamins, and antioxidants. It was found that the addition of M. oleifera leaves in the feed had no negative impact on the development and survival of the insects, while an increase in their nutritional value was recorded. More specifically, an increase in the crude protein of up to 22.61% and vitamin C and A contents of up to 40.74% and 491.63%, respectively, was recorded. Therefore, the use of M. oleifera leaves as a feed additive is highly recommended for rearing T. molitor larvae to enhance the nutritional value of the insects.

“…Lately, antioxidant compounds are gaining more and more interest as a vital part of a healthy diet, aiming to prevent damage caused by oxidative stress. In addition to their health benefits, antioxidant compounds can also protect a food product against oxidation [29]. More specifically, antioxidant compounds such as butylated hydroxytoluene (BHT) are added to food products to prevent oxidative degradation.…”

Apricot kernels are known to be rich in bioactive compounds such as polyphenols, which have applications in various fields such as cosmetology and the food industry. However, the extraction of these compounds has not been extensively studied. In this study, we aimed to extract oil from apricot kernels and investigate its composition and antioxidant properties. Samples from two years of apricot cannery by-products were used in the study. We employed a common extraction procedure using hexane as a solvent, followed by an analysis of the oil’s fatty acid composition and determination of its antioxidant properties using several methods. Our results indicated that the oil extracted from apricot kernels is rich in oleic and palmitoleic acids, which exhibit health benefits. As regards the volatile compounds of the oil, 2-methyl propanal, benzaldehyde, and benzyl alcohol were detected as the main compounds. Benzaldehyde was also found to be the main component of the essential oil of the kernel. Furthermore, the oil exhibited low antioxidant activity, as demonstrated by its ability to scavenge free radicals. Overall, our findings suggest that apricot kernels are a valuable source of oil with potential applications in the food and cosmetic industries.

“…According to Commission Regulation (EC) No 796/2002 (Annex XB) [26], the fatty acid content of the samples was determined by making the appropriate fatty acid methyl esters (FAMEs). FAMEs were analyzed according to a previous study [27]. In brief, 0.1 g of extracted fat was diluted with 2 mL of n-hexane.…”

Lentils are known to be an integral part of a nutritionally balanced diet. Their sprouts are considered even more nutritional since they contain phytonutrients that confer health benefits. As such, incorporating them into a human diet can be advantageous. In this study, seeds from brown and black lentils were germinated aiming to study the changes in their nutritional value after they were grown for different amount of days to different lengths. Since the sprouts can be consumed at various stages of their growth, four growth stages were studied. For each stage, three batches were grown, and one sample of each batch was randomly picked and analyzed in triplicates. The sprouts were examined for their nutritional value. To this end, their content of proteins and carbohydrates was determined, as well as their content in carotenoids and vitamin C. Moreover, emphasis was placed on the phytochemical compounds contained in the sprouts. As results indicate, lentil sprouts not only exhibit high nutritional value but they are also rich in antioxidant compounds. More specifically, an increase of up to 18.8% in the protein content was recorded for 15 cm length sprouts (compared to lentil seeds), accompanied by a decrease in the carbohydrate content of up to 68.9%. Carotenoids and vitamin C content increased up to 224% and 389%, respectively. Additionally, a 34% increase in the polyphenol content was recorded. Moreover, a direct correlation between sprout length and nutritional value was observed, using principal component analysis (PCA) and multivariate correlation analysis (MCA).
