“…The results obtained in the phytochemical assays suggest that the Annonaceae extracts may have different antimicrobial activities because differences in the composition of the secondary metabolites were found. According to previous studies, the antimicrobial activity depends on the type of metabolite present (Maillard, 2002), which can exhibit different modes of action or be associated with microorganisms that more effectively overcome the effect of a compound or adapt to it (Berić et al, 2018;Çördük et al, 2017;Gavrilović et al, 2016;Ji et al, 2016;Maya et al, 2021).…”

Public health concerns increase due to microbial propagation and the resistance to existing drugs; therefore, new alternatives are sought, such as the use of natural sources that are antimicrobial agents. Thus, the aim of this study was to evaluate the antibacterial potential of ethanolic extracts of seeds of the species Annona muricata (L.), Annona cherimola (Miller), Annona glabra (L.), Annona reticulata (L.), Rollinia mucosa ([Jacq.] Baillon) and Annona montana (Macfad.) of the Annonaceae family cultivated in Colombia. The bacterial strains correspond to: Staphylococcus aureus (Rosenbach), Enterococcus faecalis ([Andrewes and Horder] Schleifer and Kilpper-Bölz), Bacillus subtilis ([Ehrenberg] Cohn), Escherichia coli ([Migula] Castellani and Chalmers) and Pseudomonas aeruginosa ([J.Schröter] Migula). The antibacterial activity evaluation was performed using the agar diffusion method, each microorganism was inoculated in the medium in a concentration range of 0.2-0.5% v/v and the activity was measured by measuring the inhibition halo. A phytochemical assay was performed to identify the main metabolites to which the activity was attributed. Among the results obtained, it was found the extract of A. montana showed activity against the five bacterial strains, followed by A. glabra; the highest percentage of inhibition achieved was of A. cherimola with 79.86±3.81% activity against E. faecalis; A. reticulata and R. mucosa presented susceptibility only against two bacterial strains, the contrary, the extract of A. muricata did not present any response. The main types of metabolites identified and those attributed to antibacterial potential corresponded to alkaloids, saponins and terpenoids. The above indicates that the plants extract of Annonaceae showed antimicrobial effects. This suggest that species of this family are potential sources of compounds with antibacterial properties, which broadens the knowledge of natural extracts of Colombian materials for use in pharmacotherapy and as alternative for synthetic antibacterial agents.

“…When compared with conventional heat treatments such as pasteurization, it offers numerous advantages, among which stand out, it prevents the loss of nutrients such as vitamin C and allows to preserve the organoleptic properties of the product. Several studies have evaluated these effects on fruit juices, demonstrating significant differences in the color, smell, and taste of the juices before and after heat treatment (Villareal et al, 2013).…”

The modern consumer values those components that can promote their well-being and help them reduce the risk of diseases the use of steviolglucosides as a sweetener in the formulation of foods is promising. The study evaluated the tangential microfiltration for clarification and conservation of blackberry juice sweetened with dried leaves of stevia. Two ceramic membranes were evaluated. The tests were performed at 35°C in concentration mode at a constant transmembrane pressure and tangential velocity. The formulation of the juice was defined through sensory evaluation tests. Volume, flow permeate, temperature, and pressure input and output were registered. The results of the variables analyzed in the process, as well as the physicochemical characterization of clarified juice, helped define the operating conditions for draw two formulations of microfiltrated juice, sweetened with stevia or sucrose, and thus evaluate the effectiveness of microfiltration as a conservation treatment. Aciduric microorganisms were quantified; molds and yeasts were carried out in the generated pasteurized samples stored at five different temperatures (5, 20, 30, 37, and 45°C). The recovery permeate juice obtained was 84.62%. The permeate Flow (Jp), exhibited higher values at 40L/hm2. Also, the concentration of stevioside and rebaudioside A in the retentate increased with advancing ultrafiltration. A significant variation in color, turbidity, and soluble solids, was observed, unlike the pH. Also, its chemical and microbiological stability is confirmed that allows you to preserve quality during 27 days of storage.
