La investigación tuvo como preámbulo un diagnóstico que se efectúo a través de la verificación bibliográfica y preentrevistas a expeertos, quienes indicaron que la fotografía de Brüning es un legado que no se está aprovechando por considerarse documento único en su género, no existe otro igual debido a que Brüning fue el pionero en la etnofotografía en el Perú, sin embargo, ya en ese tiempo otros estudiosos habían hecho lo mismo en lugares como Egipto. Esto impulsó la presente investigación, trazándose como objetivo principal construir un plan de comunicación visual para la reconstrucción de la historia lambayecana basado en el análisis de la fotografía documental de Brüning. La presente investigación es de diseño hermeneútico interpretativo y etnográfico con propuesta, según el enfoque es cualitativa y pertenece al paradigma naturalista, de acuerdo con la fu...

The purpose of this systematic review was to investigate the potential of Nostoc seaweed, also known as Cushuro, as a nutritional supplement in various food products, and its possible benefits in combating public health problems, generally anemia and malnutrition. The methodology used included an exhaustive review of theoretical and empirical sources, with questions formulated following the PICOC format and the PRISMA method. Specific keywords were established and search equations were developed in the Scopus database. In addition, criteria were applied to select articles that met the necessary requirements. Initially, 4932 relevant studies were found, and after applying rigorous methodological criteria, 86 articles were selected that turned out to be relevant to this research. The analysis of these 30 articles allowed significant results to be obtained, highlighting that 19 of them high...

Organic agriculture is highly valued internationally as it results in significant economic gains for the value chains of various food products. Within the organic certification process, the identification of agrochemical residues in food is vital for screening production lots that come from organic and/or conventional crops. Currently, the analysis of agrochemical residues is performed with highly sophisticated techniques such as liquid chromatography (LC) and gas chromatography (GC) coupled to mass detectors (MS), these techniques are highly expensive and complex. The present review provides insights into how the combination of vibrational spectroscopy with appropriate chemometric techniques (multivariate statistics) can be used to develop methods for classification and quantification of agrochemical residues in various food matrices in a simple way, avoiding the use of toxic reagents, ...

The present study addresses a systematic literature review (RSL) on the current development of bioplastics as a sustainable alternative due to their degradability. The methodology consisted of an exhaustive search in the Scopus database using keywords about bioplastics, biodegradables, starch, among others. Inclusion and exclusion criteria were applied, finally obtaining 30 relevant articles published in the last 5 years (2018 - 2023). The results show that the main types of bioplastics in development are biodegradable plastics from fossil resources, compostable and bio-based. The degradability time varies between 6 months to 10 years depending on the materials, although few studies specify this information. The most used additives in the production of bioplastics are plasticizers, thickeners and emulsifiers. The most commonly used biodegradable materials and products include corn, potat...
