Dyslipidemia is an important modifi able risk factor for cardiovascular and metabolic diseases, which are responsible for a large number of mortality and disability cases around the globe. Different strategies have been used within the treatment of dyslipidemia, including lifestyle modifi cations, pharmacologic therapy, as well as functional foods and nutraceuticals. Functional foods have been used worldwide since ancient times, particularly, the prehispanic civilizations utilized several as medicinal foods. In the current pandemic of dyslipidemia as well as the nutritional transition, particularly in Latin America, the use of native functional foods represents an attractive target for the treatment and/ or prevention of these conditions. In this mini-review, evidence regarding different functional foods such as cacao, amaranth, chia, nopal, spirulina, as well as their nutraceutical compounds, including fl avonoids, omega-3 PUFAs, fi ber, prebiotics, lovastatin, c-phycocyanin, among others, and their mechanism of action are presented and discussed. Although such foods certainly are considered as attractive potential agents to target dyslipidemia thus decrease the associated cardiometabolic risk, we conclude that for most of the presented functional foods there is currently not enough evidence to support its recommendation and every-day use.

Objective. To characterize the fibrolytic enzymatic activity of Pleurotus ostreatus-IE8 and Fomes fomentarius-EUM1 in sugarcane bagasse (BCA); to evaluation of the kinetics of in vitro production of BCA treated by solid fermentation (FS), crude enzyme extract (ECE) of P. ostreatus-IE8 and Fibrozyme®. Materials and methods. In fungi measured radial growth rate ( Vcr ) and biomass production in two culture media (with or without nitrogen source); activity of xylanases, cellulases and FS on BCA at 0, 7 and 15 d. The chemical analysis and kinetic analysis of in vitro gas production in 4 treatments (ECE adding enzymes obtained from the direct addition FS or FS ), witness (Fibrozyme®) and a control without addition and analyzed by a was completely randomized design. Results. Xylanases (7 d ) showed 6.32 and 5.50 UI g-1 initial substrate dry weight (SSi) for fungi P. ostreatus-IE8 and F. fomentarius-EUM1 , respectively ; P. ostreatus-IE8 scored higher activity of laccases (10.65 g -1 UI SSi) and F. fomentarius-EUM1 (1.90 UI g-1 SSi) cellulases. The ECE of P. ostreatus-IE8 and commercial enzyme did not differences (p>0.05). In the chemical composition or the gas production kinetics. The 4 treatments evaluated decreased values of the variables measured in the kinetics of gas production compared to the control (p≤0.05). Conclusions. The ECE of P. ostreatus-IE8 was similar to commercial enzyme degradation in vitro, so it is feasible to use pre-digest high fiber products.

Oyster mushroom (Pleurotusostreatus), nopal (Opuntia ficus-indica) and amaranth (Amaranthus spp.) are pre-Hispanic foods widely consumed in Mexico. However, there are no standard products developed with these ingredientsas functional cookies. This study evaluated the impact of partial replacement (50%) of whole-wheat flour (WWF) with three formulations of P. ostreatus, nopal and amaranth flours (POF, NF and AF, respectively) on the nutritional/antioxidant properties of fortified cookies. The proportion of the flours’ ingredients (WWF:AF:NF:POF) were 100% WWF (traditional cookies), 50:35:10:5 (F1), 50:30:15:5 (F2) and 50:40:5:5 (F3). Proximal composition, phenolic/flavonoid contents, and ABTS•+ scavenging activity were determined in flours and cookies.POF, NF and AF possess a high nutritional value comprising polyphenols/flavonoids and a significant antioxidant potential. Total protein, ash and flavonoids were higher in fortified cookies than in controls. Cookies prepared with F2—the highest nopal level—contained 5.29% of dietary fiber and five times higher polyphenol content than control cookies. The ABTS•+ scavenging ability was similar in the three enriched cookies (87.73–89.58%), but higher than that in traditional cookies (75.60%). The applicability of POF/NF/AF for replacing up to 50% of WWF in the production of functional cookies was demonstrated without compromising products’ acceptability.This research promotes renewable local bioresouces for a sustainable agri-food chain, especially edible mushrooms.

Barley (Hordeum vulgare L.), and its derivatives, ranks fourth in cereal production worldwide, and the Pleurotus species are among the most efficient types of lignocellulolytic white-rot fungi. The objective of this research study was to evaluate the degradation of barley straw and barley rootless with an inoculum of Pleurotus to improve their nutritional availability as a food source for ruminants. Two experiments were conducted; the first was to determine the effects of inoculation of Pleurotus sapidus (Schulzer) Sacc. (PS) in barley straw (BS), barley rootless (BR), and a 75% BS and 25% BR mixture (M). The second experiment was to evaluate the same substrates in vitro ruminal fermentation. Barley rootless had better organic matter (OM) degradability than BS after 24 h incubation with PS. The protein content in BR was higher than in BS (P < 0.01). Enzyme activities had the highest concentration from the start of fermentation, and in vitro dry matter (DM) degradability in BS and BR increased after 8 and 24 d fermentation, respectively (P < 0.05). Propionic acid concentration was enhanced after 16 d fermentation in BR (P < 0.5). The use of BS combined with BR exhibited better fermentation; this result provides relevant information for integrating BR with other substrates and improving the use of straw, which can be more nutritionally available for feeding ruminants.

Aims:To evaluate the application of spent Pleurotus ostreatus substrates, enriched or not with medicinal herbs, as a source of anti-inflammatory compounds.Subjects and Methods:P. ostreatus was cultivated on five different substrates: Barley straw (BS) and BS combined 80:20 with medicinal herbs (Chenopodium ambrosioides L. [BS/CA], Rosmarinus officinalis L. [BS/RO], Litsea glaucescens Kunth [BS/LG], and Tagetes lucida Cav. [BS/TL]). The anti-inflammatory activity of aqueous extracts of spent mushroom substrates (SMSs) (4 mg/ear) was studied using an acute inflammation model in the mouse ear induced with 2.5 μg/ear 12-O-tetradecanoylphorbol13-acetate (TPA).Results:Groups treated with BS/CA, BS/RO, and BS/LG aqueous extracts exhibited the best anti-inflammatory activity (94.0% ± 5.5%, 92.9% ± 0.6%, and 90.4% ± 5.0% inhibition of auricular edema [IAO], respectively), and these effects were significantly different (P < 0.05) from that of the positive control indomethacin (0.5 mg/ear). BS/TL and BS were also able to reduce TPA-induced inflammation but to a lesser extent (70.0% ± 6.7% and 43.5% ± 6.6% IAO, respectively).Conclusions:Spent P. ostreatus substrate of BS possesses a slight anti-inflammatory effect. The addition of CA L. to mushroom substrate showed a slightly synergistic effect while RO L. had an additive effect. In addition, LG Kunth and TL Cav. enhanced the anti-inflammatory effect of SMS. However, to determine whether there is a synergistic or additive effect, it is necessary to determine the anti-inflammatory effect of each medicinal herb.
