“…In the case of neutralizing substances, most of the samples did not show the presence of these substances in the milk analyzed, but in some investigations, the use of these substances was evident, as in the results obtained in [ 31 , 32 , 43 ], as shown in Figure 18 . These chemicals are used to mask the acidity of raw milk, and generally have serious consequences for public health in high doses as they are able to cause the development of kidney stones, or become deposited in body fluids and soft tissues [ 111 , 112 ].…”

“…Regarding the presence of hydrogen peroxide (which is not allowed by Ecuadorian legislation), there is wide variability among the studies; for example, in the research of [ 31 , 32 , 82 ], its levels are farthest from the zero point or the line of incidence, so they disagree with the majority of studies ( Figure 19 ). In Ecuador, the use of hydrogen peroxide is prohibited because it is used to mask the acidity of milk [ 111 , 112 ]; however, there are studies that indicate the benefits of using it to preserve milk for up to 8 h at room temperature without losing its organoleptic characteristics, even in the Ecuadorian tropics, where ambient temperatures can be above 25 °C [ 113 ].…”

With the objective of evaluating the quality parameters of raw milk in Ecuador between 2010 and 2020, a systematic review and meta-analysis of 73 studies on raw milk produced in different regions of Ecuador was performed. Under the random effects model, effect size and heterogeneity were determined vs. climatic region both among analyses and studies, with Cochran’s Q, I2 and Tau (π) statistics. For all the variables, it was observed that there was great heterogeneity (I2 > 90%) among the studies; additionally, it was found that climatic region had an influence only among the variables arsenic, mercury, pH and total solids, and it was greater in the coastal region than the Inter-Andean region. The mean values of the physicochemical characteristics of the milk (titratable acidity, ash, cryoscopy, fat, lactose, pH, protein, non-fat solids and total solids) in the great majority of these studies were within the range allowed by Ecuadorian regulations. As for the hygienic quality of raw milk (total bacterial count, somatic cell count and presence of reductase), although the mean values were within those determined by local legislation, it should be noted that the range established by Ecuadorian regulations is relatively much higher compared to other regulations, which possibly means that there is a high presence of bacteria and somatic cells in raw milk. Finally, the presence of several adulterants (added water) and contaminants (AFM1, antibiotics and heavy metals) was confirmed in the milk, in addition to other substances such as eprinomectin, zearalenone and ptaquilosides, whose presence can be very dangerous, because they can be hepatotoxic, immunotoxic and even carcinogenic. In conclusion, there is great variability among the studies reviewed, with the physicochemical characteristics being the most compliant with Ecuadorian legislation; the hygienic characteristics, adulterants and contaminants of raw milk require greater attention by producers and local authorities, so that they do not harm the health of consumers and the profitability of producers in Ecuador.

“…La leche al ser considerada alimento básico durante todas las etapas de la vida en el ser humano, demanda de forma indispensable que la industria solicite a los productores, requisitos para establecer su calidad de acuerdo con estándares higiénicos-sanitarios, fisicoquímicos y microbiológicos (6). La determinación de contaminantes, tales como materia extraña, formaldehídos, oxidantes, derivados clorados, entre otros, que se encuentran presentes en la leche cruda bovina es un tema de importancia para la salud pública a nivel mundial, ya que, junto con sus derivados, constituyen productos de consumo masivo, destinándose aproximadamente el 75% de la producción para el consumo humano (7).…”

Objetivo. Evaluar la calidad higiénico-sanitaria, fisicoquímica y microbiológica de leche cruda bovina destinada a la venta, producida en un establo familiar y en tres mercados públicos del estado de Tabasco. Materiales y métodos. La calidad higiénico-sanitaria se determinó de acuerdo con la información general del predio, instalaciones, proceso de ordeño, limpieza y desinfección. La calidad fisicoquímica se determinó evaluando proteínas totales, caseína, grasa butírica, lactosa, sólidos no grasos y densidad. La calidad microbiológica fue determinada mediante la acidez titulable, prueba de alcohol, contenido de células somáticas, potencial de óxido-reducción, materia extraña, inhibidores bacterianos y bacterias mesofílicas aerobias. Resultados. La leche producida en el establo familiar, fue evaluada con la máxima calidad fisicoquímica y microbiológica en referencia a los estándares que evalúa la normatividad oficial mexicana establecidas en México por el Consejo para el fomento de la calidad de la leche y sus derivados, A. C. En cambio, la leche en los tres mercados públicos se consideró de rechazo, indicando posible contaminación durante los procesos de ordeña, así como en el manejo y transporte hacia los mercados públicos. Conclusiones. Las muestras de leche provenientes de los mercados públicos se consideraron no aptas para consumo humano ni para elaboración de subproductos.

Academic data management has become an increasingly challenging task as research evolves over time. Essential tasks such as information retrieval and research networking have turned into extremely difficult operations due to an ever-growing number of researchers and scientific articles. Numerous initiatives have emerged in the IT environments to address this issue, especially focused on web technologies. Although those approaches have individually provided solutions for diverse problems, they still can not offer integrated knowledge bases nor flexibility to exploit adequately this information. In this article, we present REDI, a Linked Data-powered framework for academic knowledge management and research networking, which introduces a new perspective of integration. REDI combines information from multiple sources into a consolidated knowledge base through state-of-the-art procedures and leverages semantic web standards to represent the information. Moreover, REDI takes advantage of such knowledge for data visualisation and analysis, which ultimately improves and simplifies many activities including research networking.
