“…In a study by M’hiri et al (2018) [ 183 ], the retention of total phenol and total flavonoids contents was the highest (68.73 and 61.44%, respectively), when combined microwave-air drying (90 W/75 °C) was applied on an industrial lemon by-product. Oil extraction from microwave-dried Hass avocados resulted in high quality and stable avocado oils when compared to those obtained from air-dried avocados [ 184 ]. Regarding antioxidant retention, microwave drying was also advantageous for raspberries, for which antioxidant retention was 41.7%, 1.7 times compared to hot air drying alone [ 185 ].…”

Plants need to be protected against pests and diseases, so as to assure an adequate production, and therefore to contribute to food security. However, some of the used pesticides are harmful compounds, and thus the right balance between the need to increase food production with the need to ensure the safety of people, food and the environment must be struck. In particular, when dealing with fruit and vegetable wastes, their content in agrochemicals should be monitored, especially in peel and skins, and eventually minimized before or during further processing to separate or concentrate bioactive compounds from it. The general objective of this review is to investigate initial levels of pesticide residues and their potential reduction through further processing for some of the most contaminated fruit and vegetable wastes. Focus will be placed on extraction and drying processes being amid the main processing steps used in the recuperation of bioactive compounds from fruit and vegetable wastes.

“…These fatty alcohols have been reported to exhibit antiviral, cytotoxic, antifungal, trypanocidal, and antioxidant activity [10,11,12,13,14,15,16,17,18,19,20,21]. Phenolic compounds (Figure 2, and Table 1) of different chemical classes from simple organic acids such as gallic acid to larger flavonoids, anthocyanidins, and tocopherols were isolated from Persea species with significant antioxidant, neuroprotective and cardioprotective activities [22,23,24,25,26,27,28]. The antioxidant properties of avocado were also ascribed to their carotenoid content in many studies [24,28,29,30] (Figure 3).…”

“…Phenolic compounds found in avocado were shown to reduce oxidation, inflammation, and platelet aggregation [65]. Several studies have reported that different parts of the avocado plants contain potent phenolic antioxidants such as chlorogenic-, quinic-, succinic-, pantothenic-, abscisic-, ferulic-, gallic-, sinapinic-, p -coumaric-, gentisic-, protocatechuic-, 4-hydroxybenzoic-, and benzoic- acids, quercetin, quercetin-3-glucoside, quercetin-3-rhamnoside, vanillin, p -coumaroyl-D-glucose, catechins, (−)-epicatechin, and procyanidins (Table 3) [2,28,84,89,90,91,92,93,94,95,96,97]. Among the different parts of avocado investigated in several studies, leaf, peel, and seed extracts have shown consistently greater antioxidant capacity compared to that of the pulp [84,91,94,96,97,98,99,100,101,102,103,104,105,106].…”

The Odyssey of Bioactive Compounds in Avocado (Persea americana) and Their Health Benefits

et al. 2019

View full text Add to dashboard Cite

Persea americana, commonly known as avocado, has recently gained substantial popularity and is often marketed as a “superfood” because of its unique nutritional composition, antioxidant content, and biochemical profile. However, the term “superfood” can be vague and misleading, as it is often associated with unrealistic health claims. This review draws a comprehensive summary and assessment of research performed in the last few decades to understand the nutritional and therapeutic properties of avocado and its bioactive compounds. In particular, studies reporting the major metabolites of avocado, their antioxidant as well as bioavailability and pharmacokinetic properties, are summarized and assessed. Furthermore, the potential of avocado in novel drug discovery for the prevention and treatment of cancer, microbial, inflammatory, diabetes, and cardiovascular diseases is highlighted. This review also proposes several interesting future directions for avocado research.

“…Mango tree exhibits droughts periods tolerance; however for the southern Brazil the specie is sensitivity to the occurrence of frosts, demonstrating the importance of agroclimatic studies to improve the production (Olson and Alvarado-Cárdenas, 2016). As a segment of agriculture, mango production presents risks that meteorological elements provide in the variability in production and sensitivity in the management of fruit species (Comer, 2018;Conceição et al, 2018;De Matos et al, 2018;Borges et al, 2019;Medeiros et al, 2018;Dai et al, 2019;Santana et al, 2019;Shezi et al, 2019).

Mango cultivation is one of the key economic agricultural activities of fruit in Brazil. In Southern Brazil, mango presents vulnerability thanks to its frost sensitivity, indicating the relevance of climate studies to improve the production and agricultural techniques, in the context of sustainable agriculture and climate change. Agroclimatic zoning should be one of the first information to be considered when starting its cultivation. The objective of this study is to carry out climatic risk zoning for mango tree (Mangifera indica) in the basin of Paraná River III, Brazil. Meteorological data from 43 stations, from 1976 to 2018, were used. The climatic risk analysis was based on the requirements of the mango for precipitation, water balance, average annual temperature, and frost tolerance. The occurrence of frosts is the key restrict factor for production in the area of study. This meteorological factor restricted mango cultivation in the central-eastern portion of the basin. In other areas, the risk is present but the mango cultivation is recommended.
