Access to food products is becoming more and more complex due to population growth, climate change, political and economic instability, disruptions in the global value chain, as well as changes in consumption dynamics and food insecurity. Therefore, agri-food chains face increasingly greater challenges in responding to these dynamics, where the digitalization of agri-food systems has become an innovative alternative. However, efforts to adopt and use the technologies of the fourth industrial revolution (precision agriculture, smart agriculture, the Industrial Internet of Things, and the Internet of Food, among others) are still a challenge to improve efficiency in the links of production (cultivation), processing (food production), and final consumption, from the perspective of the implementation of Food Informatics technologies that improve traceability, authenticity, consumer confidence, and reduce fraud. This systematic literature review proposes the identification of barriers and enablers for the implementation of Food Informatics technologies in the links of the agri-food chain. The PRISMA methodology was implemented for the identification, screening, eligibility, and inclusion of articles from the Scopus and Clarivate databases. A total of 206 records were included in the in-depth analysis, through which a total of 34 barriers to the adoption of Food Informatics technologies (13 for the production link, 12 for the processing link, and 9 for the marketing link) and a total of 27 enablers (8 for the production link, 11 for the processing link, and 8 for the marketing link) were identified. Among the barriers analogous to the three links analyzed are privacy and information security and high investment and maintenance costs, while the analogous enablers are mainly government support.

Macrofungi are among the most promising sources of biologically active natural products with nutritional qualities and therapeutic values. In this work, the nutritional value of nine species of wild macrofungi from Ibague-Tolima (Colombia) was evaluated. In addition the antioxidant, antimicrobial and cytotoxic activities of an ethanol:water (70:30) extract of wild basidiomata were evaluated. The wild mushrooms’ nutritional potential showed that the genus Pleurotus and Lentinus have the best protein percentages, with 18.4% and 18.5%. The nine extracts evaluated managed to stabilize the two radicals evaluated; however, lower IC₅₀ was found for Phellinus gilvus and Ganoderma australe extracts. The results showed that Trametes coccinea, Pleurotus floridanus and Ganoderma australe extracts were the most effective as antimicrobials, with high inhibition percentages against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae. Antifungal activity results against Rhizopus oryzae, Penicillium sp. and Aspergillus niger showed that the nine extracts were effective at the concentrations tested. Considering cell viability against isolated leukocytes, seven of the nine extracts showed percentages higher than 50% of cell viability. This research describes the nutritional value of nine wild macrofungi in Colombia and their potential for antimicrobial, cytotoxic and antioxidant activity.

La pulpa de Theobroma grandiflorum, conocido comúnmente como copoazú, es utilizada para la preparación de mermeladas, jugos, yogurt, néctares y dulces, y sus semillas son aprovechadas para la elaboración de cupulate, bebida equivalente al chocolate. En Colombia existe poca información sobre las propiedades de este fruto, especialmente de los ácidos grasos presentes en las semillas, las cuales podrían ser de gran interés para la industria alimentaria. En este estudio se identificó y analizó el contenido de ácidos grasos presentes en el aceite extraído de las semillas de copoazú en madurez fisiológica y sus índices de calidad, además, se midió el potencial antioxidante del aceite mediante el ensayo ORAC, lo anterior como aproximación al conocimiento del uso potencial alimenticio o nutracéutico de uno de los frutos exóticos de la amazonia de poco conocimiento en Colombia. La identificación de ácidos grasos reveló que hay mayor contenido de ácido oleico (36,3%), esteárico (29,27%) y palmítico (7,26%), los índices de calidad, como la saponificación (1,88,15 mg KOH/g muestra), yodo (49,33 g de I/g de grasa) y acidez (1,04 mg KOH/g muestra), muestran que el aceite de copoazú podría ser utilizado en la industria alimentaria y cosmética.
