1. Extracción optimizada y purificación parcial de invertasa aislada de S. Cerevisiae en puré de durazno
Abstract The extraction was performed using an autolysis process where enzymes degrade cell structures and release the cytoplasmic contents to the extracellular medium. The autolysis process was carried out in shake flasks with different agitation speeds (50 - 350 rpm) and the concentration of sodium bicarbonate (50 -350 mM NaHCO3) at 40 ° C for 24 hours, u

2. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO ANALÍTICO POR DISPERSÃO DA MATRIZ EM FASE SÓLIDA E CROMATOGRAFIA EM FASE GASOSA ACOPLADA A ESPECTROMETRIA DE MASSAS PARA DETERMINAÇÃO DE PESTICIDAS EM AMOSTRAS DE OVOS DE GALINHA (GALLUS GALLUS DOMESTICUS). / DEVELOPMENT AND VALIDATION OF ANALYTICAL METHOD FOR SCATTERING MATRIX SOLID PHASE AND GAS CHROMATOGRAPHY COUPLED TO A MASS SPECTROMETRY DETERMINATION OF PESTICIDES IN SAMPLES OF CHICKEN EGGS (GALLUS GALLUS DOMESTICUS).
The eggs are of great nutritional value. Its biochemical composition indicates the source of proteins, lipids, vitamins and minerals. However, undesirable chemical compounds can form part of this constitution. The pesticides, when applied irregularly, can represent a serious health risk to consumers if detected above the maximum residue limits, can be identi

3. Comportamento higroscópico do suco de laranja liofilizado / Higroscopic behavior of freeze-dried orange juice
The higroscopic behavior of freeze-dried orange juice, with added maltodextrins and lactose and mechanical mixtures with this additives was studied through the kinetics and isoterms of water sorption in different temperatures. It was evaluated the spectral characteristics, in the visible and ultraviolet range, and the vitamin C content from samples of freeze
