I am a Food Chemistry Professor at the University of Sao Paulo (USP), Sao Carlos Institute of Chemistry (IQSC), Sao Paulo State, Brazil. I have a Ph.D. in Food Science from Campinas State University (UNICAMP) and a Post-doc in Food Science and Technology from the University of California (UC-Davis). My current research focuses on developing analytical methods to answer questions regarding food flavor, food quality, and the health aspects of food components. My research group uses analytical tools like statistical design and response surface techniques (Central Composite Design, Box Behnken Design, Doehlert Design, and Mixture Design) to optimize sample preparation steps (mostly SPME and LPME). We also develop and validate methods for high-performance liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) to assess the composition of flavor volatile compounds, phenolic compounds, fatty acids profile, short-chain fatty acids, and residues of toxicants (such as acrylamide, furan, furfuryl alcohol, and organochlorines) in food, feed, and beverages. Currently, our research group also focuses on the synthesis and physical-chemical characterization of natural deep eutectic solvents (NADES) for the extraction of bioactive compounds from agro-industrial wastes. We also have strong international collaborations with the University of California (UC-Davis), United States (US). (Source: Lattes Curriculum)

Rice is one of the most widely cultivated cereals globally, ranking third in terms of production, standing only behind corn and wheat. Brazil stands out as the world's leading rice producer outside the Asian region, thereby contributing to the annual generation of approximately one million tons of rice bran. A significant portion of this byproduct is underutilized, predominantly employed …
The principles of 'green chemistry' are receiving more and more importance due to the need to reduce the use of classical organic solvents, commonly classified as toxic, explosive, and polluting in industrial processes. In this sense, the use of natural deep eutectic solvents (NADES) is an innovative way to replace conventional organic solvents in industrial processes. This research aims …
Polychlorinated biphenyls (PCBs) are compounds of well-known toxicity that could be found as contaminants in the environment and in food, particularly meat, fish and milk. The nutritional characteristics and the drinking milk habit since childhood turns the non-occupational human exposure to PCBs by milk ingestion a concern to us. This project aims : i) to develop and optimize a SPME/GC-M…

In this research, NADES will be tested for their ability to stabilize food-grade aromas. For this purpose, natural citrus aromas such as orange and/or tangerine essential oil will be subjected to the microencapsulation process by forming inclusion complexes with cyclodextrins and/or by spray drying. For the use of spray drying, essential oil, NADES, potato starch maltodextrin and ultrapur…
A growing and consistent food production capable of meeting the exponential increase in the world's population is crucial to tackle the issue of global hunger. Furthermore, this increase in food production must be perfectly aligned with the sustainable development goals outlined in the United Nations' 2030 agenda, particularly Goal 12, which addresses responsible consumption and productio…

In this research, the mixture modeling response surface tool will be used to optimize the proportion of components of mixtures of natural deep eutectic solvents (NADES). All synthesized NADES will be characterized physicochemically through measurements of: pH, viscosity, density, solubility, by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR) and thermograv…
Citrus production is especially important for the economy of Brazil and for the São Paulo state. The country is the world's largest producer and exporter of orange juice. In addition, the 'Tahiti' acid lime is the third most exported fruit by Brazil. In 2019, the country exported more than US$ 104,617 million worth of 'Tahiti' acid lime. The state of São Paulo leads the 'Tahiti' acid lime…
The aim of this research is to evaluate the chemical composition of strawberries covered with edible films made with pomegranate peel extract (Punica granatum L.), chitosan and gelatin. For this, pomegranate peel extracts will be obtained using environmentally friendly solvents such as natural eutectic solvents (NADES). The extracts obtained will have their phenolic components identified …

Edible coatings are membranes or films formed by biopolymers, which aim to reduce the transpiration and respiration rates of fruits. The use of that biocoatings can extend the shelf life of foods while preserving their sensory characteristics. Chitosan and gelatin are two natural polymers that stand out in the area, due to their non-toxicity, biodegradability, and ease film formation. The…
The preference and acceptance of food generally are related to the need for some type of heat treatment. During cooking, the Maillard Reaction occurs, which gives rise to several chemical compounds that promote flavor, texture, and color to foods. However, some of the Maillard Reaction products are toxic to humans, such as acrylamide, furan and furan derivatives (ie, 2-methylfuran, 3-meth…
