“…However, plantderived products are rich in polyphenols, a naturally occurring class of compounds with exceptional antioxidant properties [30]. Polyphenols and their subclass, flavonoids, are present in high amounts in apricots [31]. However, polyphenols are compounds of variable polarity, and as such, their presence in AKO should not be taken for granted.…”

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.

Stone fruits, such as the apricot (Prunus armeniaca L.), are frequently consumed. As such, a substantial volume of apricot waste is generated at each stage of the food supply chain, including harvesting, processing, packaging, warehousing, transportation, retailing, and eventual consumption. This generates tons of waste annually on a global scale. The significant amounts of phenolics present in these wastes are primarily responsible for their antioxidant capacity and the subsequent health advantages they provide. As such, apricot pulp by-products could be a valuable reservoir of bioactive compounds, such as tocopherols, polyphenolic compounds, proteins, dietary fibers, etc. Moreover, apricot kernels are also recognized for their abundance of bioactive compounds, including polyphenols and tocopherols, which find utility in diverse sectors including cosmetology and the food industry. Both conventional and green methods are employed, and generally, green methods lead to higher extraction efficiency. The antimicrobial properties of apricot kernel essential oil have been widely recognized, leading to its extensive historical usage in the treatment of diverse ailments. In addition, apricot kernel oil possesses the capacity to serve as a viable resource for renewable fuels and chemicals. This review examines the potential of apricot waste as a source of bioactive compounds, as well as its utilization in diverse applications, with an emphasis on its contribution to health improvement.

“…Currently, much attention is being paid to the topic of the valorization of fruit byproducts, and their applications in various industries. A recent investigation looked at apricot pulp waste as a source of antioxidant polyphenols and carotenoid pigments and the study concluded that apricot waste can indeed be a rich source of bioactive compounds [112]. Another paper highlighted that plum by-products can be reincorporated into the food supply chain in view of the circular economy due to their antioxidant and antimicrobial activities [113].…”

Research-Gap-Spotting in Plum–Apricot Hybrids—Bioactive Compounds, Antioxidant Activities, and Health Beneficial Properties

Plum–apricot hybrids are successful backcrosses of plums and apricots resulting in plumcots, pluots, and apriums. A topic search on plums, apricots, and plumcots shows that extensive information exists on the agro-morphology, genotyping, bioactive substances, and nutritive value of the genus Prunus, and plums and apricots, in particular. However, when search results for plum–apricot hybrids were evaluated for the period 2010–2023, only a few papers focused partially on the topic of their metabolomics. A database search (Scopus, PubMed, and Google Scholar) exposed that less than 10 articles/year appeared in Scopus on the topic of plum–apricot hybrids, 618 papers were found on Google Scholar (2010–2023), and only 2 results were found in PubMed for the same period using the same keywords. This shows the grand research opportunity and the need for providing a thorough chemical characterization of the existing plum–apricot hybrids. This review aims at schematizing the available information about plum–apricot hybrids (with reference to their parents), identifying the gaps about their bioactive compounds, antioxidant activities, and health beneficial properties, as well as pointing to future perspectives in terms of fruit hybrid characterization.
