Kim YT, Kimmel R, Wang X. A New Method to Determine Antioxidant Activities of Biofilms Using a pH Indicator (Resazurin) Model System. Molecules 2023; 28:molecules28052092. [PMID: 36903338 PMCID: PMC10003940 DOI: 10.3390/molecules28052092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 02/05/2023] [Accepted: 02/07/2023] [Indexed: 02/25/2023] Open
Abstract
Biopolymeric films were prepared with gelatin, plasticizer, and three different types of antioxidants (ascorbic acid, phytic acid, and BHA) corresponding to different mechanisms in activity. The antioxidant activity of films was monitored for 14 storage days upon color changes using a pH indicator (resazurin). The instant antioxidant activity of films was measured by a DPPH free radical test. The system using resazurin was composed of an agar, an emulsifier, and soybean oil to simulate a highly oxidative oil-based food system (AES-R). Gelatin-based films (GBF) containing phytic acid showed higher tensile strength and energy to break than all other samples due to the increased intermolecular interactions between phytic acid and gelatin molecules. The oxygen barrier properties of GBF films containing ascorbic acid and phytic acid increased due to the increased polarity, while GBF films containing BHA showed increased oxygen permeability compared to the control. According to "a-value" (redness) of the AES-R system tested with films, films incorporating BHA showed the most retardation of lipid oxidation in the system. This retardation corresponds to 59.8% antioxidation activity at 14 days, compared with the control. Phytic acid-based films did not show antioxidant activity, whereas ascorbic acid-based GBFs accelerated the oxidation process due to its prooxidant activity. The comparison between the DPPH free radical test and the control showed that the ascorbic acid and BHA-based GBFs showed highly effective free radical scavenging behavior (71.7% and 41.7%, respectively). This novel method using a pH indicator system can potentially determine the antioxidation activity of biopolymer films and film-based samples in a food system.

Abstract
The purpose of this research was to extract tea leaf phenols using Microwave Assisted Extraction (MAE) method at 3 levels of microwave power (high, medium high and medium) and investigated the influence of physco chemical properties of whey protein and gelatine biopolymer using tea leaf extract as crosslink materials at different concentration (5%, 10% and 15% (v/v)). MAE method gave significantly effect on phenolic content. High level power of MAE gave higher phenolic content of tea leaves extracts. Tea leaves extracts as crosslinked agent of biopolymer gave highly significant effect on the stability of the emulsion, the emulsion activity and foaming power. SDS-PAGE protein profile showed increase molecular weight with the addition of tea leaf extract, it can be presumed presence crosslinked both on whey protein or gelatine.

Abstract
Abstract
Gelatin films were prepared using different initial concentrations (1 to 30%) in H2O (w/v). The solid films were kept at four different environmental conditions at 20%, 43%, 75%, and 90% relative humidity, until complete equilibrium was achieved. Spin–spin relaxation (T
2) and spin–lattice relaxation (T
1) times of the samples were determined using a low-field nuclear magnetic resonance (NMR) spectrometer operated at 40 MHz proton (1H) Larmor frequency and were correlated with the molecular mobility of the system influenced by the humidity conditions and initial concentration. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were performed as well to investigate the thermal properties of the samples. The results indicate an increase in molecular mobility of the gelatin films with the increase of storage humidity independent of the initial concentration and suggest that the dynamic of the films depends on the amount of the water in the amorphous region of the film.
