In-vitro antioxidant activities of the extract were evaluated based on total phenolic and flavonoid contents, DPPH radical scavenging activity, and metal chelating ability prior to the dip treatment. The quality parameters, including total volatile base nitrogen (TVB-N), trimethylamine nitrogen (TMA-N), and free fatty acid (FFA), were significantly (p < .05) reduced in WRE treated steaks compared to the control (CT) steaks. WRE treatment of fish steaks significantly controlled the lipid oxidation parameters of thiobarbituric acid reactive substances (TBARS) and peroxide value (PV). Total plate count (TPC) of CT sample was higher than the treated sample and remained within the limit of 7 log10 cfu/g at the end of storage. As per the sensory analysis, shelf life of Deccan mahseer was determined to be 15 days for WRE t...

The time period selected for this study is presented in phases: Phase A from 1990 to 2000) and Phase B (from 2001-2011). The relation between Pakistan and the US during the above-mentioned phases can be categorized into periods of engagements (where Pakistan enjoyed the status of the most trusted ally without compromising its regional interest) and periods of disengagements (where Pakistan faced US sanctions and was left alone to deal with the aftermath of the Afghan war and the war on terrorism). Hence, the understudied period provides an interesting insight into how Dawn and Jang framed the issue of US-Pakistan relations on their editorial pages.

The correlation of dietary cholesterol with heart ailments has led people to become more health conscious and in this scenario the present study was carried out to investigate the monthly variations in Indian squid to aid in better decision making by consumers. Squid samples [Uroteuthis (Photololigo) duvaucelii] were collected in quadruplicate on monthly basis for the period of one year (2015-2016) and subjected to analysis for cholesterol, non-saponifiable matter (NSM) and proximate composition. The cholesterol content of squid was highest (279 mg%) and lowest (7.3 mg%) during the months of April and December with respect to total length and size, respectively. A monthly variation in proximate composition of squid with respect to the total length and size was observed. No correlation observed between fat content and cholesterol in squid. Significant difference in cholesterol content was observed monthly in the squid samples. NSM content (0.23%) was negligible and undetectable in the samples.

Hence, in the present study, beetroot peel and whole radish was chosen. Beet root peel extract (BPE) and Whole radish extract (WRE) was prepared using water and screened for the antibacterial compound against various food borne pathogen using modified well diffusion assay. Then the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) level was identified for the various food pathogens. Results showed that direct crude extract of both beetroot peel and radish having the antibacterial activity against Staphylococcus aureus, Escherichia coli, Salmonella typhi and Vibrio cholera. WRE was more effective than the BPE. It is concluded that antibacterial activity of the plant derived material is truly depends upon the extraction method and the type of solvent used for extraction. Two to four fold higher concentration of water based extraction is needed to get the effect of fat solvent based extraction. BPE and WRE can be a promising source of antimicrobial agents to control the specific food borne pathogens. The modified well diffusion assay can be used for the initial screening of large number of unfiltered the plant extract and combined method of well diffusion assay with MIC would be more suitable procedure to identify the exact antibacterial activity of the crude unfiltered plant materials.

Prior to the dip treatment of steaks, the antioxidant properties of the extract were evaluated by in-vitro assays following the standard protocol. Beetroot peel extract was further evaluated for the characterisation of phenolic and flavanoid compounds by LC-MS/MS analysis. Beetroot peel extract (20 %, v/v) was used for the dip treatment based on the in-vitro antioxidant assay and preliminary sensory analysis. Quality changes in terms of chemical characteristics, drip loss, microbiological and sensory characteristics were examined at regular intervals of 30 days.
