    Calidad de la leche y del suero costeño de los municipios Turbaco, Arjona y Carmen de Bolívar – Colombia
    (Corporación Universitaria Lasallista, 2012) Granados Conde, Clemente; Acevedo Correa, Diofanor; Torres Gallo, Ramiro
    Introduction. Suero costeño is an autochthonous product from the Colombian Caribbean region, and it is obtained by naturally fermenting raw milk, so it keeps all of its nutritional ingredients. Objective. Determine and compare the physical/chemical and microbiological characteristics of the milk and of the suero costeño from Arjona, Turbaco and Carmen de Bolivar. Materials and methods. The physical/ chemical and microbiological characteristics of the milk and of the suero costeño were determined and compared according to what is established by the Colombian regulations. Results. The cryoscopic index of the milks produced in Turbaco, Arjona and Carmen de Bolivar does not meet the regulations, while the microbiological tests are within the ranks allowed. The sueros costeños from Carmen de Bolivar, Arjona and Turbaco contain Escherichia coli, fecal Coliforms and Staphylococcus aureus coagulase above the levels allowed. The suero costeño produced industrially meets the microbiological and physical/ chemical quality standards demanded by the regulations. Conclusion. The high microbial load contained in not industrially produced sueros costeños is a consequence of the deficient hygienic and sanitary conditions under which they are produced in the aforementioned towns.

    Verification of Information of the Labeling of Dairy Products of Cartagena de Indias Supermarkets
    (Unilasallista Corporación Universitaria, Editorial Lasallista, 2021) Carrascal Sánchez, Juan; Acevedo Correa, Diofanor; Fortich, Ana María; de Arco Rosano, Deniles; Montero Castillo, Piedad
    Labelling is used to help people choose foods for the nutrients that benefit them most but sometimes the content expressed on the label is not correct. Objective:To compare the data expressed on the labels of the different brands of milk, milk powder, cream, coastal cheese and yogurt with those found in this research. Materials and methods: Samples were taken from local markets, label information was taken, and a bromatological analysis of each product was also performed to compare with the values given by the manufacturer on the label. Results: The values of the parameters declared on the labels in most of the brands analyzed were lower than the actual values found and the data from the Colombian Technical Standard (NTC) and the United States Department of Agriculture (USDA) for each product. To prevent this type of event from continuing, greater control of the companies by the control bodies is necessary. Conclusions: Most valuable dairy products did not comply with national and international labelling rules, as they did not declare, reduce or increase the percentages of most of the parameters on the label
