    Abstract Essential molecules are embedded within the millenary crop Tropaeolum tuberosum (mashua); these compounds are critical for the Andean people’s traditional diet and extensively utilized by the pharmaceutical industry in Peru. In the Andean region, conventional cropping techniques generate microtubers susceptible to a viral infection, which substantially endangers mashua’s production. Therefore, we developed an innovative in vitro technique condition for enhancing the agriculture process for micro tubers production. The temporary immersion system (TIS) permits the production of high-quality microtubers in a reduced space, a lower amount of time, and in large quantities compared with tubers grown under traditional conditions. To obtain T. tuberosum’s microtubers via TIS, we propagated seedlings, utilizing TIS-RITA® vessels. A set of immersion frequency times were evaluated. Interestingly, results showed that immersion at 2 min every 3 h was more beneficial compared with 2 min every 5 h based on microtubers produced after 10 weeks from the treatments, revealing an efficient frequency setting which outputted improved microtubers quality and production.

    Abstract Tropaeolum tuberosum Ruíz and Pav. “Mashua” is a crop from the Andean region associated with preventing chronic degenerative diseases. This study evaluated the content of bioactive compounds (phenolics, glucosinolates, carotenoids, and ascorbic acid) in twenty-seven Peruvian mashua morphotypes. Furthermore, three morphotypes (MAC 067, MAC 092, and MAC 123) were selected to evaluate further the effect of methyl jasmonate (MeJA) on the accumulation of bioactive compounds. Phenolic content in the mashua morphotypes ranged from 2990.76 ± 273.5 mg/kg to 24,217.36 ± 1144 mg/kg; whereas carotenoids ranged from 12.8 ± 0.6 mg/kg to 85.8 ± 3.1 mg/kg. Moreover, total glucosinolate content ranged from 65 ± 11 mmol/kg to 1289 ± 65 mmol/kg. The different mashua morphotypes showed low levels of ascorbic acid (lower than 5 mg/kg) compared with other crops. Except for glucosinolates, MeJA application augmented the level of bioactive compounds, showing increases of up to 150.1%, 535.0%, and 542% for total phenolics, carotenoids, and ascorbic acid, respectively. Results indicated that mashua is an excellent source of phenolics and glucosinolates, whereas it contains adequate levels of carotenoids and low levels of vitamin C. MeJA application during postharvest represented a simple approach to increase the content of bioactive compounds in mashua.

    Abstract BACKGROUND: In 2015, The United Nations (UN) established 17 Sustainable Development Goals (SDGs) by 2030. In Latin America, the Pacific Alliance is integrated by Chile, Colombia, Peru, and Mexico, which the scientific activity is focused on the scientific production from research and academic institutions. In this study, the main goal was to analyze the scientific production (2015–2019) in the Pacific Alliance related to “zero hunger” as SDG. The bibliometric analysis of the scientific literature was carried out using the Scopus database with search terms related to zero hunger and validated by Elsevier. We analyzed the annual production of original articles, productive journals, leading institutions, funding agencies, authors, and the most influential original. RESULTS: Our results showed that the Pacific Alliance produced 2215 (81.0%) original articles, which is the fraction of non-excluded outputs with an annual growth rate of 12.62%, Mexico was the leading country, Nutrición Hospitalaria was the most active journal, and The Universidad Autónoma de Mexico was the leading institution and CONACYT as the leading funding institution. CONCLUSION: As conclusion, the scientific production of the Pacific Alliance is showing positive substantial changes, which reflects the main research themes related to zero hunger, such as food security, sustainable agriculture, and malnutrition to achieve this SDG by 2030.

    Abstract Potato tocosh is a naturally processed potato for nutritional and curative purposes from traditional Peruvian medicine. The aim of this study was to investigate the acute and sub-acute toxicity of tocosh flour (TF). For sub-acute toxicity, TF was administered orally to rats daily once a day for 28 days at doses of 1000 mg/kg body weight (BW). Animals were observed for general behaviors, mortality, body weight variations, and histological analysis. At the end of treatment, relative organ weights, histopathology, hematological and biochemical parameters were analyzed. For acute toxicity, TF was administered orally to mice at doses of 2000 and 5000 mg/kg BW at a single dose in both sexes. Body weight, mortality, and clinical signs were observed for 14 days after treatment. The results of acute toxicity showed that the median lethal dose (LD
