Not from concentrate (NFC) orange juice is minimally processed, natural-appearing food, and has become more popular. Sterilization is an important stage for NFC orange juice production. Here we present a comprehensive analysis of the effect of sterilization on the metabolites of NFC orange juices, including three thermal (pasteurization, high-temperature short time, and ultrahigh temperature) and one nonthermal (high hydrostatic pressure) method. A total of 108 metabolites, including 59 volatiles and 49 nonvolatiles were identified in orange juice. Of which, only butyl butanoate and 3-carene were detected in fresh orange juice. Sterilization significantly changed the metabolites of orange juice, and different methods caused various changes. Esters were downregulated by both thermal and nonthermal sterilization, while most flavonoids and terpenes were upregulated. With comparative analyses of three thermal sterilization, we found that high temperature and relatively short-time treatment preserved esters and ascorbic acid more effectively than low temperature and prolonged treatment. Aldehydes, however, were the opposite. Nonthermal sterilization is effective in preserving the metabolites of orange juice, especially for esters, terpenes, and flavonoids. In addition, 19 distinct metabolites were characterized between thermal and nonthermal samples by chemometrics analysis.These findings provide a new sight of the optimization of sterilization methods and references for different types of NFC orange juice identification. K E Y W O R D Schemometrics analysis, data fusion, high hydrostatic pressure, metabolomics, not from concentrate orange juice, sterilization Practical Application: This study provides a reference for the optimization of sterilization methods and identification of HHP and thermal NFC orange juice and also benefits the purchase of consumers.Ruixue Sun and Ranran Xing contributed equally to this work.

“…To test the seal quality of brick-type packages using the pressure differential leak tester, the distance between the vertical conveyor belts and thus the force on the packages were optimized. Sivaramakrishna, Raspante, Palaniappan, and Pascall (2007) describes this equipment and how it works to test the quality of induction seals and plastic caps on PET bottles. A modification of this method was used for leak testing of the brick-type packages.…”

“…If leak detection, as described in this study, is to be used to perform online leak testing of these packages, the detector must be positioned before the folding steps along the production line. The remainder of the optimization of the leak tester and the establishment of the pass/fail threshold was performed similar to the procedure Sivaramakrishna et al (2007) established for the PET bottles. As will be described later on in this paper, there were also significant differences in the method of creating leaks in the seals, dye testing and seal strength determination between the bricktype packages and the PET bottles.…”

“…Therefore, the requirements of container closure integrity impose high standards of maintaining sterility [3]. There are several conventional methods for testing the vial closure, such as blue dye ingress, pressure rise measurement, residual gas analysis and high voltage leak inspection, but they cannot give quantitative measurements [4][5][6][7][8]. Some methods like low temperature infrared spectroscopy [9], pulsed nuclear magnetic resonance [10] and X-ray diffractometry [11] have been implemented for on-line and non-destructive testing.…”
