The objective was to evaluate the oxidative stability of soybean oil with the addition of antioxidant of isaño (Tropaeolum tuberosum Ruiz & Pavón) and TBHQ during potato frying, analyzed at 0, 1,5, 2,5 and 3,5 hours At 180 ° C + 10 ° C, with frying intervals of potatoes every 30 minutes, performing eight frying events. To evaluate, peroxide, acidity, dienes and trienes were tested for indices. During the frying, soybean oil samples with the addition of extract Isaño showed less formation of dimer and triers compared to the sample of  soybean oil with TBHQ, indicating greater protective effect on the oxidative stability of soybean oil during frying, without However, this sample showed a higher correlation compared to the oil samples with the addition of Isano extract, due to the presence of residues of sugars in said extracts. The peroxide index and free fatty acid percentag...

The research aims to formulate a food mixture based on quinoa, cañihua, barley, corn, beans and soy using cooking-extrusion technology. The optimal mixture was made with formulations of better chemical computation, the mixture containing 28.8% pearl quinoa, 9.25% cañihua, 5.00% barley, 6.00% bean, 3.00% corn, 8.00% soybeans, 29.50% being favored of sugar, 8.00% of vegetable oil, 0.20% of essence, 2.00% of tricalcium phosphate and 0.25% of vitamins. The mixture was subjected to the extrusion cooking process using 15% humidity, 180° C temperature and 457 rpm, obtaining a gelatinization index 98.30% considering a good cooking index of the instant mixture. The functional characteristics of the selected instant mixture were evaluated obtaining, absorption index with 6.1%, solubility index with 19.8%, expansion index with 1.64 cm and nitrogen solubility index with 35%. The quality of the in...

Therefore in this research the shelf life time of vacuum-packed cured guinea pig meat using different concentrations of sodium chloride was determined and the effects produced sodium chloride on the proximal chemical composition of guinea pig meat cured were evaluated, giving a longer shelf life time, the analytical methods used were: pH, TBA value, water activity, microbiological tests: aerobic mesophilic count, Staphylococcus aureus, Salmonella sp. and Escherichia coli. For proximal chemical evaluation were performed tests of % moisture, % ash, % protein and% fat, making a comparison between the 1% concentration of sodium chloride with a standard sample (C0%). Based on the results it was observed that the concentration of sodium chloride 1% provided greater shelf life 12 days compared to concentrations of 3% and 5% sodium chloride they showed lifetime of 10 and 8 da...
