“…Because SPAs are low-cost, widely available, and highperformance compared to natural antioxidants, food manufacturers prefer to use SPAs. Although they are effective at prolonging the shelf life and preventing the oxidative rancidity of food, the addition of excess antioxidants to food might produce toxicities or mutagenicities (Xiu-Qin, Chao, Yan-Yan, Min-Li, & Xiao-Gang, 2009). In the USA, EU, and other countries, these antioxidants are authorized as food additives and can be added alone or in combination up to a final concentration of 0.01% or 0.02% (European Commission, 2011, FDA., 2015USDA Foreign Agricultural Service, 2011).…”

“…Various analytical methods have been reported for the determination of SPAs in edible oils, including high-performance liquid chromatography (HPLC) with UV, photodiode array detector (PDA) (Andrikopoulos, Brueschweiler, Felber, & Taeschler, 1991;Wang et al, 2012), liquid chromatography time-of-flight mass spectrometry (LC-TOF/MS) (Xiu-Qin et al, 2009) gas chromatography (GC) (González, Gallego, & Valcárcel, 1999;Yang, Lin, & Choong, 2002), gas chromatograph-mass spectrometry (GC-MS) (Guo, Xie, Yan, Wan, & Wu, 2006), capillary electrophoresis (CE) (Jaworska, Szuliń ska, & Wilk, 2005), and thin-layer chromatography (TLC) (Ragazzi & Veronese, 1973). The Association of Official Analytical Chemists (AOAC) and American Oil Chemists' Society (AOCS) official methods are based on the HPLC-UV determination of SPAs (AOAC official method 983.15, 1995;AOCS official method Ce 6-86, 1997).…”

Proximate analysis of Barringtonia racemosa (putat) leaves was carried out and total phenolic content (TPC) was measured using total phenolic assay, also known as the Folin Ciocalteu (FC) assay. Antioxidant activities of the methanolic and aqueous extracts were evaluated by ferric reducing antioxidant power (FRAP) assay; the free radical scavenging capacity was determined by 1,1-diphenyl-1-picrylhydrazyl radical scavenging capacity (DPPH) assay. Proximate analysis showed that the leaves contained 70.52% moisture, 0.96% ash, 2.54% protein, 0.26% fat, 1.38% crude fiber, and 25.71% carbohydrates. The TPC amount exhibited by the methanolic extract was 1585.20±25.54 mg GAE/100 g sample, which was higher compared with the aqueous plant extract with 1314.12±66.19 mg GAE/100 g (p<0.05). Significant (p<0.05) difference in terms of the flavonoid content was observed between the extracts obtained by methanolic and aqueous extraction. Total condensed tannin content showed significant (p<0.05) difference between the methanolic and the aqueous extracts, which were 33.11±0.61 mg CE/100 g and 13.38±0.87 mg CE/100 g, respectively. Methanolic extract of Barringtonia racemosa leaves showed a higher DPPH scavenging activity than the aqueous extract. FRAP value for the methanolic extract of the sample was higher than the aqueous extract, with a significant difference (p<0.05). Results of this study will provide a platform for the future paradigm of these potential natural sources of antioxidants in food and nutraceutical applications.

A heart-cutting two-dimensional high-performance liquid chromatography method was developed to simultaneously quantify five major proteins and seven food additives (maltol, ethyl maltol, vanillin, ethyl vanillin, benzoic acid, sorbic acid, and saccharin sodium) in milk and milk powders. In this two-dimensional system, a Venusil XBP-C4 column was selected in the first dimension for protein separation, and a Hypersil ODS-2 C18 column was employed in the second dimension for additive separation; a two-position, six-port switching valve was used to transfer the targets (additives) from the first dimension to the second dimension. Method validation consisted of selectivity, response function, linearity, precision, sensitivity, and recovery. In addition, a conventional one-dimensional high-performance liquid chromatography method was also tested for comparison. The two-dimensional method resulted in significantly improved recovery of the food additives compared to the conventional method (90.6-105.4% and 65.5-86.5%, respectively). Furthermore, this novel method has a simple one-step sample preparation procedure, which shortens the analysis time, resulting in more efficient analysis and less solvent usage.
