“…In vivo studies performed by Athaydes et al [61] demonstrated that avocado seed extracts with ethyl acetate have gastroprotective activity and can be used as an adjunctive treatment for indomethacin-induced gastric mucosal injury. Uchenna et al [145] have shown promising component values in avocado seeds as a source of energy, protein, and bioactive phytochemicals to stimulate growth and metabolism. Additionally, the authors reported that the inclusion of avocado seeds in diets has also lowered cholesterol levels and suppressed hyperglycemia in rats.…”

Fruit Seeds as Sources of Bioactive Compounds: Sustainable Production of High Value-Added Ingredients from By-Products within Circular Economy

et al. 2019

The circular economy is an umbrella concept that applies different mechanisms aiming to minimize waste generation, thus decoupling economic growth from natural resources. Each year, an estimated one-third of all food produced is wasted; this is equivalent to 1.3 billion tons of food, which is worth around US$1 trillion or even $2.6 trillion when social and economic costs are included. In the fruit and vegetable sector, 45% of the total produced amount is lost in the production (post-harvest, processing, and distribution) and consumption chains. Therefore, it is necessary to find new technological and environmentally friendly solutions to utilize fruit wastes as new raw materials to develop and scale up the production of high value-added products and ingredients. Considering that the production and consumption of fruits has increased in the last years and following the need to find the sustainable use of different fruit side streams, this work aimed to describe the chemical composition and bioactivity of different fruit seeds consumed worldwide. A comprehensive focus is given on the extraction techniques of water-soluble and lipophilic compounds and in vitro/in vivo functionalities, and the link between chemical composition and observed activity is holistically explained.

“…The effects of avocado were studied in the seed ( 37 – 39 ), leaf ( 40 – 44 ), and peel ( 45 ). Of them, six used extracts to determine its effects ( 38 , 40 – 44 ). Of the extracts, four were aqueous ( 40 , 42 – 44 ), one was ethanolic ( 40 ), two were methanolic, ( 40 , 42 ), and one was hydroalcoholic ( 43 ).…”

The Effects of Avocado Waste and Its Functional Compounds in Animal Models on Dyslipidemia Parameters

2021

Ischemic heart disease and stroke are two main causes of death that have prevailed for more than 15 years. Dyslipidemia and its parameters like hypercholesterolemia, hypertriglyceridemia, increase in low-density cholesterol, and a reduction of high-density cholesterol have been related with heart disease and risk of stroke. Approaches to improve the health and specifically reduce the risk of heart disease, such as medications and dietary interventions have been effective, but there are other potential sources of biological compounds that could have an effect due to their antioxidant properties. Avocado is a commonly consumed fruit especially its pulp, while the peel, seed, and leaf are usually discarded as waste. Some researchers have reported antioxidant, hepatoprotective, gastroprotective, lipid-lowering, and hypoglycemic effects in these wastes. In this review article, we have summarized the current evidence on the effect of biological compounds from avocado waste on dyslipidemia parameters in preclinical models. Also, we have included the compound extracted and the extraction method from the selected articles.

“…Numerous studies have shown a positive health effect after the inclusion of avocado byproducts on the diet of living organisms, which could be mainly to the presence of bioactive compounds. Thus, Uchenna, Shori, and Baba () concluded that the inclusion of avocado seeds in the diet of rats may partially influence the feeding and growth performance. It lowered the cholesterol levels in blood, suppressed high blood glucose, and improved liver glycogen storage capability of the rats.…”

Tropical fruits represent one of the most important crops in the world. The continuously growing global market for the main tropical fruits is currently estimated at 84 million tons, of which approximately half is lost or wasted throughout the whole processing chain. Developing novel processes for the conversion of these byproducts into value‐added products could provide a viable way to manage this waste problem, aiming at the same time to create a sustainable economic growth within a bio‐economy perspective. Given the ever‐increasing concern about sustainability, complete valorization through a bio‐refinery approach, that is, zero waste concept, as well as the use of green techniques is therefore of utmost importance. This paper aims to report the status on the valorization of tropical fruit byproducts within a bio‐refinery frame, via the application of traditional methodologies, and with specific attention to the extraction of phenolics and carotenoids as bioactive compounds. The different types of byproducts, and their content of bioactives is reviewed, with a special emphasis on the lesser‐known tropical fruits. Moreover, the bioactivity of the different types of extracts and their possible application as a resource for different sectors (food, pharmaceutical, and environmental sciences) is discussed. Consequently, this review presents the concepts of tropical fruit biorefineries, and the potential applications of the isolated fractions.
