This study aim to evaluate the effect of Casimiroa edulis and Crataegus pubescens aqueous extracts on cardiac lipotoxicity in obese rats. Both extracts decrease cardiac hypertrophy and steatosis in high fat and fructose (HFF)‐diet‐fed obese rats. C. pubescens decreases the cardiac content of 16 and 18 carbon‐length fatty acids, whereas C. edulis extract does not alter the fatty acid profile. Regarding lipotoxic compounds, C. pubescens reduces the cardiac content of 16 and 18 carbon‐length ceramides and diacylglycerols, whereas C. edulis extract reduces ≥20 carbon‐length lipotoxic compounds. Both extracts down‐regulate fatty acid synthase (Fasn) and acetyl‐CoA carboxylase (Acaca) (lipogenesis), glyceril‐3‐phosphate acyltransferase (Gpat) (diacylglycerol synthesis) and serine palmitoyltransferase 1 (Spt1) (ceramide synthesis), and up‐regulate carnitine palmitoyltransferase 1 (Cpt1) and acyl‐CoA dehydrogenase (Acadm) (β‐oxidation), and the greatest effect is observed with C. pubescens. In addition, C. edulis exerts the greatest cardiac anti‐inflammatory activity, whereas C. pubescens shows the highest cardiac antioxidant activity. The cardioprotective effect of C. pubescens may be associated with its content of (−)‐epigallocatechin gallate, (+)‐catechin, chlorogenic acid, caffeic acid, and β‐campesterol, whereas the beneficial effect of C. edulis may be related to its high content of steroidal saponins and alkaloids. Therefore, these results demonstrate that both herbal aqueous extracts ameliorate cardiac lipotoxicity in HFF‐diet‐fed rats, and C. pubescens exerts a greater beneficial effect. Practical Applications: This study proposes the characterization of fatty acids and lipotoxic compounds (ceramides and diacylglycerols) of cardiac tissue in combination with the determination of the expression of specific genes related to lipid metabolism to identify the mechanisms associated with the cardioprotective effects of herbal extracts. The results obtained in this study demonstrate the cardioprotective potential of Casimiroa edulis and Crataegus pubescens aqueous extracts through the modulation of cardiac lipid metabolism in high fat and fructose diet fed obese rats. Therefore, these herbs can be used for the development of functional beverages or the extraction of bioactive compounds with cardioprotective effect.

“…DFC are composed of less than 9% lipids and total dietary fibre (TDF) of at least 50% [12], and they are successfully applied in the food industry [5] to increase nutritional value taking advantage of their physicochemical properties for food formulations. In this regard, some fruit and vegetable by-products, such as peels, pomace, and bagasse, with a high content of dietary fibre, have succeeded in obtaining DFC and their inclusion in foods formulations as functional ingredients [13][14][15].…”

Dietary fibre concentrates (DFC) obtained from fruit and vegetable by-products are powders, mainly obtained by dehydration, used in food formulations to increase nutritional value and to improve functional properties. The modifications of insoluble, soluble, and total dietary fibres (IDF, SDF, and TDF), physicochemical properties (solubility, swelling capacity, water/oil retention capacity, pH, and tapping density), and prebiotic potential of DFC from orange, mango, and prickly pear peels obtained by freeze-drying (FD) and convective hot air-drying (HA) were studied. In vitro faecal fermentation was used to evaluate the short-chain fatty acid (SCFA) production as a prebiotic indicator. TDF in FD orange was 5.5 g·100 g−1 higher than that in the HA sample, whereas HA increased TDF in prickly pear (9.5 g·100 g−1). No differences in fibre composition were observed in mango DFC. The physicochemical properties mostly affected by dehydration treatment were solubility and swelling capacity. HA increased SCFA production in orange peel (48 mmol·g−1 higher) but decreased it in mango and prickly pear (15 and 19 mmol·g−1 lower). Butyrate production of HA orange DFC was comparable to that obtained with the positive control (4.5 mmol·g−1). No production of propionate or butyrate was observed after 6 h fermentation in mango samples, despite the high SDF content (≈20 g·100 g−1). A decrease of the SDF : TDF ratio produced by the drying method improved the SCFA production.

“…The presence of phenolic compounds (see Table ) was related to α‐amylase inhibition, and antioxidant and antiradical activities, along with a body weight reduction of 8% in obese rats (Amaya‐Cruz et al., ; Rojas‐Garbanzo, Zimmermann, Schulze‐Kaysers, & Schieber, ). In the same line, the highest extraction yield of phenolic compounds was achieved with a solution of 60% methanol or pure water and a further purification via ultrafiltration membranes (Sukeksi, Che Hassan, Nik Sulaiman, Rashidi, & Davazdah Emami, ).…”

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.
