Determination of the geographical origins of frozen concentrated orange juice via pattern recognition

Multivariate Analysis for Classification of Commercial Orange Juice Products by Volatile Constituents Using Headspace Gas Chromatography

“…Country of origin was determined for several samples of frozen concentrated orange juice (FCOJ) from either Florida or Brazil (11). Based on earlier results showing concentrations of 5 elements as significant in distinguishing between geographical locations (12), a relatively simple pattern recognition program involving a "decision vector" clearly discriminated between concentrated juices from Florida and Brazil.…”

Characterisation of honey produced from different fruit plants of northern India

“…In recent years, multivariate chemometric techniques such as principal component analysis (PCA) and linear discriminate analysis (LDA) have been widely used for the classification of wines, olive oils, concentrated orange juice, species of fish and types of milk according to the kind of feed (Bayer et al. , 1980; Derde et al.…”

Use of Infrared Spectroscopy and Chemometrics for the Authentication of Fruit Purees

“…In food systems, they have been applied to the differentiation of honeys of two geographical origins (Pena Crecente and Herrero Latorre, 1993), as well as brandies of different nationalities (Schreier and Reiner, 1979), milk from different animal species (Smeyer- Verbeke et al, 1977), and peppermint oils of different origins (Chialva et al, 1993). As far as fruits are concerned, the origin of orange juice and frozen concentrated orange juice (Florida or Brazil) was investigated (Nikdel et al, 1988;Bayer et al, 1980).…”
