Taking advantage of the protein value present in lupine flour without shell with a percentage of 58.17% protein where unripened hard cheeses were made, from different concentrations of lupine flour and carrageenan, resulting in cheeses with different levels moisture. Through an InfoStat statistical package with a randomized complete block design (DBCA), in a factorial arrangement A*B+1, the best treatment was determined based on the percentage of moisture that corresponds to treatment nine (a3b3) with a formulation 3% lupine flour and 0.05% carrageenan. Physical analyzes were performed at the best treatment: density 1.04g/ml, titratable acidity 0.31g/kg, pH 6.1; also chemical analysis: total moisture 53.57%, dry matter 46.43%, protein 21.61%, fiber 1.07%, fat 19.58%, ash 6.20%, and; microbiological analysis: total coliforms 10UFC/g, absence of escherichia coli and salmonella, sthaphylococcus aureus 5UFC, molds 10UFC, yeasts 10UFC/g Through a sensory evaluation carried out with the best treatment, the organoleptic characteristics were determined, such as: color, odor , flavor, texture and acceptability, where high scores between 4 and 5 were obtained. Finally, this research generates positive impacts, both technical, social, environmental and above all economic, associated with water retention performance; The project can contribute with the proposal of new dairy products with a high protein level, as well as link small producers of milk, lupine and dairy industries and all consumers who require new products with added value. |
