This study focuses on the antioxidant properties and industrial applications of essential oils from lemon (Citrus limon), matico (Piper aduncum), and spearmint (Mentha spicata). The study was descriptive and based on a literature review of research between 2017 and 2023, using the PRISMA methodology for the selection of studies. It was found that Citrus limon essential oil is notable for its high proportion of monoterpene hydrocarbons and d-limonene, effective in neutralizing free radicals and combating premature skin aging, and has applications in aromatherapy, the food industry, cosmetics, and pharmaceuticals. It was also found that Piper aduncum oil, rich in dillapiole, exhibits anti-inflammatory activity, although its antioxidant activity is low compared to other standards, it has applications in alternative medicine, sustainable agriculture, and as a biopesticide. On the other hand,...

The grains of tarwi (Lupinus mutabilis S.) have a high protein content, and are also very rich in some essential amino acids, such as lysine. However, the extrusion parameters significantly affect the protein contents of the generated products. The main objective of the study was to determine the best extrusion temperature in a snack made from tarwi and rice flours. For the production of the snack, tarwi flour (Lupinus mutabilis Sweet) was used, in three concentrations (8, 10 and 12%) and three proportions of rice flour (Orysa sativa) (88, 90 and 92%). The extrusion parameters were: extrusion temperature (100, 110, 115) ° C, screw rotation speed 1560 rpm, feed speed 1kg / min, blade speed 630 rpm, water flow 19.5 ml / min and diameter of the outlet nozzle 0.6 mm. A multilevel factorial design was used, achieving 9 experimental runs. The results of the sensory and proximal chemical analy...

Peru has several foods with high lipid content (especially oils), rich in omega fatty acids (ω-3 and ω-6) that are widely studied for their anti-inflammatory (ω-3) and pro-inflammatory (ω-6) effects. However, ω-3 and ω-6 are susceptible to oxidation resulting in accelerated deterioration of the oils. The objective of this work was to determine the oxidative stability index (OSI) of vegetable (seeds) and animal (anchoveta) oils from Peru, with high ω-3 and ω-6 contents, in order to compare oxidation kinetic parameters and shelf life. For this purpose, the Rancimat accelerated oxidation method was used, whose working parameters were: air flow (F = 25 L/h), sample weight (M = 3 g) and temperature range (T = 60-140 °C). The results indicated that the OSI values, as well as the shelf-life projection (T = 25°C) were in the following order: olive oil > chestnut > sesame > sac...

Cocoa butter is widely used in the food field, especially in the production of chocolates, so it is obtained mainly by pressing and solvent methods. The present research work was aimed at comparing both extraction methods in order to determine the qualitative and quantitative effect on the fatty acid profile. The qualitative results obtained by mid-infrared spectroscopy (MIR) indicated similar presence of functional group vibrations throughout the wavelength range studied. At the quantitative level, gas chromatography indicated that the major fatty acids (palmitic, stearic and oleic) did not present significant differences (p<0.05). The use of hydraulic pressing is a much more environmentally friendly method, although its great disadvantage was found in the extraction yield.
