Preparation and application of a flaxseed meal protein film containing lemongrass (Cymbopogon citratus) oil

Abstract

Flaxseed meal protein (FMP) films were prepared, and their mechanical properties (tensile strength (TS) and elongation at break (E) values), water vapour permeability, optical properties and thermogravimetric analysis were evaluated. Briefly, 5 g FMP, 2 g fructose and 0.03 g ferulic acid were required for the optimal preparation of an FMP film. The TS and E values of the FMP film were 13.12 MPa and 61.90%, respectively. Furthermore, different amounts of lemongrass oil (LE) were incorporated into the FMP film to prepare an antimicrobial film. Wrapping pen shell adductor muscle with the FMP film containing 1.0% LE reduced the counts of inoculated Listeria monocytogenes and Escherichia coli O157:H7 compared with those in the control, after storage at 4°C for 12 day. Consequently, packaging with FMP film containing 1.0% LE can be useful in improving the quality of pen shell adductor muscle during storage.

Antimicrobial activity of buckwheat starch films containing zinc oxide nanoparticles against Listeria monocytogenes on mushrooms

“…The antimicrobial activity of the BS/ZnO-N films was determined using viable cell count assay as described by Lee et al (2016). Each strain of L. monocytogenes (KCTC 13064, ATCC 19115) was cultured in 25 mL of brain-heart infusion (BHI) at 37°C for 16 h. All bacterial cultures were harvested by centrifugation at 3000 g at 4°C for 10 min.…”

A High-Performance Soy Protein Isolate-Based Nanocomposite Film Modified with Microcrystalline Cellulose and Cu and Zn Nanoclusters

“…Compared with other proteins, soy protein has been extensively investigated for the development of biodegradable films due to its abundance, low cost, biodegradability, and biocompatibility [ 4 , 5 ]. Soy protein isolate (SPI) is a mixture of proteins containing approximately 90% globulins.…”

Phenolic acid composition of flaxseed cultivars by ultra-performance liquid chromatography (UPLC) and their antioxidant activities: Effect of sand roasting and microwave heating

“…In a study by Hung, Hatcher, and Barker (2011) the researchers presented the first report on application of UPLC for rapid quantification of phenolic acids in cereal grains replacing the traditional HPLC system. Some of recent publications to illustrate current research practices in flaxseed have been with regard to potential application of gum from flaxseed in food or related fields (Liu, Shen, Shim, & Reaney, 2016), preparation of protein films from flaxseed meal proteins (Lee, Yang, Lee, & Song, 2016) and development of gluten-free pasta formulated with pregelatinized rice and defatted flaxseed flour (de Moura et al, 2016). Antioxidant potential of flaxseed protein or protein hydrolysates in prevention of lipid oxidation in food products has been demonstrated (Hwang, Chen, Luo, & Chiang, 2016).…”
