Vaccinium meridionale Swartz extracts and their addition in beef burgers as antioxidant ingredient

Abstract

Mortiño extracts with high TPC can be obtained by PLE. Both mortiño and its PLE extract are able to control lipid oxidation of beef burgers, but the extract is preferred from the color quality point of view. © 2017 Society of Chemical Industry.

The Antioxidant Effect of Colombian Berry (Vaccinium meridionale Sw.) Extracts to Prevent Lipid Oxidation during Pork Patties Shelf-Life

“…The 83,976.25 mg GAE/kg of TPC achieved in the CBE and elaborated in the present study is lower than that reported by Quintero-Quiroz et al [ 20 ] in a freeze-dried extract made from this fruit (139,290 mg GAE/kg). The extracts elaborated from this fruit by López-Padilla et al [ 21 ] by ultrasound-assisted extraction and pressurized liquid extraction had TPC contents between 71.70 ± 6.7 mg GAE/kg and 9.26 ± 2.52 mg GAE/kg. Different and fundamental aspects have to be considered to explain these differences.…”

“…In a way, our results are not surprising in agreement with Lorenzo et al [ 16 ], who recently published a review indicating the use of berry extracts as natural antioxidants in meat products. In the same line, López-Padilla et al [ 21 ] also reported that CB is being valorised as raw material for the recovery of rich antioxidants with the application as natural additives in meat products. The DPPH, IC 50 , ABTS ● + , ORAC, and FRAP values obtained for the CBE can be attributed to the presence of phenolics compounds with high antioxidant and radical scavenging activity [ 18 , 19 ], especially anthocyanins (e.g., monoglucosides of cyanidin and delphinidin), hydroxycinnamic acids (e.g., coumaric acid), and flavanols (e.g., quercetin derivatives).…”

“…This antioxidant capacity could be attributed to a higher level of extracted non-polar phenolic compounds and oxygenated monoterpenes in CBE that could act as direct free-radical scavengers [ 2 , 18 ]. In several studies, authors have reported ABTS ● + values for CBE of 1.034 mol TE/kg [ 21 ], CB fresh fruit (327.9 μmol TE/g), CB fresh weight (45.5 mol TE/g) [ 18 ], and CB dry weight (546.7 μmol TE/g) [ 19 ]. Moreover, values for ABTS ● + of guarana seed ( Paullinia cupana K.) (2072 μmol TE/g) [ 38 ], grape seed ( Vitis vinifera L. and Vitis labrusca L.) (2.93 g TE/g), and tea ( Camellia sinensis (L.) Kuntze) (4.06 (g TE/g) [ 37 ] have been published.…”

“…Garzón et al [ 18 ] reported that this fruit has high antioxidant activity and potential applications as a source of phytochemicals in the nutraceutical and functional food market because it is an excellent source of dietary phytochemicals such as polyphenolics compounds. More recently, several studies have been conducted to determine the phenolic profile of Colombian berry [ 19 , 20 ], as well as the application of Colombian berry extract (CBE) as an antioxidant in beef patties [ 21 ]. However, the assessment of CBE as a natural antioxidant in meat products is still scarce.…”

Sub- and supercritical fluid extraction of bioactive compounds from plants, food-by-products, seaweeds and microalgae – An update

“…Also, a great amount of polyphenols was found in the aqueous extracts, which could be responsible of the mentioned activity, with the highest content in grape fruit extract. Another example of application of PLE extracts was given by López-Padilla et al [40]. They studied the antioxidant activity of some PLE extracts from Vaccinium meridionale Swartz in order to add it in beef burgers, obtaining an optimum phenol-rich extract using a mixture of ethanol:water (1:1), 200 °C and only 15 min static extraction time.…”
