1. AUTENTICAÇÃO DE ORÉGANO (Origanum vulgare L.) ORGÂNICO UTILIZANDO ESPECTROSCOPIA NIR E QUIMIOMETRIA
In recent years, the consumption of organic foods has considerably increased. The basic difference between organic and non-organic food products is the way in which they are produced and processed, and the authenticity of these products is a current trend in food science and analytical chemistry. In this sense, the objective of this work was to propose an an

2. Isoenzyme and molecular approach for authenticating and monitoring of animal cell lines
Abstract: Authentication of cell lines is of paramount importance to validate the results from their use in biomedical research. Although isoenzyme polymorphism is the standard method, molecular methods based on mitochondrial DNA (mtDNA) have been developed to replace it. The aim of this study was the improvement of our isoenzyme electrophoretic analysis and

7. Molecular detection of adulteration in commercial buffalo meat products by multiplex PCR assay
Abstract Authentication of commercial buffalo meat products has become a market concern. This study intended to develop and validate a highly species-specific multiplex PCR assay for authentication of buffalo meat products. Four pairs of species-specific primers were used to target mitochondrial cytochrome oxidase I (COI) gene. The assay generated the expec

11. Feature Level Two -Dimensional Arrays Based Fusion in the Personal Authentication system using Physiological Biometric traits
ABSTRACT The fingerprint, knuckle print and the retina are used to authenticate a person accurately because of the permanence in the features. These three biometric traits are fused for better security. The fingerprint and knuckle print images are pre-processed by morphological techniques and the features are extracted from the normalized image using gabor f
