Rebeca Salvador-ReyesThe early detection of internal damage caused by Elasmopalpus lignosellus in fresh asparagus constitutes a challenge for the agro-export industry due to the limited sensitivity of traditional visual inspection. This study evaluated the potential of VIS–NIR hyperspectral imaging (390–1036 nm) combined with machine-learning models to discriminate between infested (PB) and sound (SB) asparagus spears. A balanced dataset of 900 samples was acquired, and preprocessing was performed using Savitzky–Golay and SNV. Four classifiers (SVM, MLP, Elastic Net, and XGBoost) were compared. The optimized SVM model achieved the best results (CV Accuracy = 0.9889; AUC = 0.9997). The spectrum was reduced to 60 bands while LOBO and RFE were used to maintain high performance. In external validation (n = 3000), the model achieved an accuracy of 97.9% and an AUC of 0.9976. The results demonstrate the viability of implementing non-destructive systems based on VIS–NIR to improve the quality control of asparagus destined for export.

Mashua (Tropaeolum tuberosum), a resilient and underutilized Andean tuber, is a high-potential nutritional and functional food innovation resource. This review surveys information on the nutritional composition, bioactive profile, and functional properties of the tuber based on a comprehensive literature search conducted in the Scopus database. The search strategy employed eight Boolean operators combining the following terms: (“Tropaeolum tuberosum” OR “mashua”) AND (“bioactive compounds” OR “functional properties” OR “glucosinolates” OR “antioxidant activity” OR “food processing”). The review included English-language research articles published between 2000 and 2025. Its diverse constituents, such as glucosinolates, phenolics, and anthocyanins, have antioxidant, anti-inflammatory, and antimicrobial activities. Technologies such as freeze-drying, microencapsulation, and 3D printing make it easier to preserve these bioactive components and ensure their use in novel food products. Although Mashua has potential, its widespread adoption remains limited by its distinct sensory characteristics and the lack of clinical validation regarding its effect on human health. To extract the full potential of mashua as a functional ingredient for the global food industry, consensus evidence exists around the need for standardized analytical methodologies, technological innovation, and sustainable value chain development.

André Rodríguez LeónJhonsson Luis Quevedo-OlayaLa implementación de sistemas de trazabilidad en la cadena de suministro de alimentos en Latinoamérica es la base para asegurar la inocuidad alimentaria y fortalecer la confianza del consumidor. Esta investigación tiene como objetivo analizar el estado actual de los sistemas de trazabilidad en las empresas alimentarias de Latinoamérica identificando dificultades y proponiendo estrategias para mejorar su implementación. Se realizó una revisión de literatura evaluando 23 artículos de diversas bases de datos académicas (Scopus, Web of Science, ProQuest, Google Scholar y SciELO), con una muestra total de 88 trabajos publicados entre 2016 y 2024. Los estudios presentan un 28 % de investigaciones aplicadas y 72 % de investigaciones básicas, utilizando metodologías descriptivas (52%), exploratorias (36%) y explicativas (12%). Los resultados revelan que tecnologías como blockchain, IoT y gemelos digitales mejoran significativamente la trazabilidad y transparencia en la cadena de suministro, permitiendo una mejor gestión y reduciendo pérdidas. Sin embargo, desafíos como la falta de infraestructura y la necesidad de capacitación técnica limitan su adopción. Se concluye que, aunque las tecnologías emergentes pueden optimizar la cadena de suministro, es esencial abordar estos desafíos para maximizar sus beneficios y promover un sistema alimentario más eficiente y sostenible en la región.

El objetivo fue evaluar la mejora en la gestión de la calidad e inocuidad en la empresa América Alimentos S.R.L., a partir de la implementación del esquema FSSC 22000+Quality en la producción de arroz fortificado destinado a programas sociales. En primera instancia, se formó un equipo de trabajo multidisciplinario comprometido con la mejora continua, luego se definieron los objetivos y alcance del sistema. A partir del análisis situacional inicial, se plantearon los escenarios estratégicos para la empresa. Asimismo, se identificaron los riesgos y establecieron acciones de mitigación, con foco en la actualización de los programas pre requisitos y establecimiento del plan HACCP. Resultado de la implementación, se verifica una reducción del 40% en productos no conformes, un incremento del 25% en eficiencia de producción y una disminución del 15% en microorganismos patógenos. Además, se logró un análisis costo-beneficio favorable con un retorno de S/ 2,88 y un VAN de S/ 121 065,26. El esquema FSSC 22000+Quality representa un paso significativo hacia la mejora de la gestión de calidad e inocuidad, puesto que, es una estrategia efectiva para obtener productos seguros y de calidad.

Jhonsson Luis Quevedo-OlayaAndré Rodríguez LeónThe Peruvian diet is recognized worldwide for its diversity and exquisiteness, which has made it an international gastronomic benchmark. Proof of this is that Peru is home to some of the best restaurants in the world, with distinctions in prestigious guides such as The World's 50 Best Restaurants and Michelin stars. But this comes at a price, since its composition is dominated by foods rich in carbohydrates and processed, which negatively affects the health of the population. This study has set itself the challenge of analyzing how nutrients interact in the daily Peruvian diet and their effect on health. To this end, a literature review was carried out with studies published between 2014 and 2024, using academic databases and rigorous selection criteria. The results show that positive interactions, such as the combination of vitamin C with non-heme iron, improve the bioavailability of key nutrients, reducing problems such as anemia. However, the presence of phytates and tannins in the diet inhibits the absorption of essential minerals, which increases nutritional deficiencies in vulnerable populations. The study concludes by making a proposal for food combinations that improve nutrient absorption and modifying cooking methods can improve the nutritional quality of the Peruvian diet.
