Food irradiation technology: Prospects and future applications
Sawera Asghar,Haris Ayub,Nauman Khalid 한국식품저장유통학회 2022 한국식품저장유통학회지 Vol.29 No.7
Food irradiation technology (FIT) is a non-thermal processing that covers all significant aspects of food processing and preservation such as shelf-life extension, natural flavour maintenance, chemical-free preservation, and pathogen reduction. Excessive irradiation dosages can have negative consequences on food, which may include a reduction in functional and sensory qualities. On the other hand, the standard dose can have a positive influence, such as phytosanitary treatments, detoxifying aflatoxins, reducing pathogenic microorganism growth, reducing allergenicity of food allergens and increasing the product's shelf life. Consumer acceptance, prejudice, incorrect information, stringent legal and regulatory restrictions, and a subsequent unwillingness of food makers and the food trade to employ the latest technology are all impediments to FIT.

The use of byproducts from the food industry and the investigation of substitute sources are becoming progressively significant in fulfilling the consumer demand for animal-based protein. This study aimed to investigate the nutritional value of mutton and fish livers and their future application as a source of high-added-value proteins for supplement formulation. We performed compositional analysis (moisture, ash, crude protein, crude fat), free fatty acid (FFA) analysis, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, and the color, peroxide value (POV), and total phenolic composition (TPC) were assessed to evaluate the nutritional value and shelf stability of mutton and fish livers. The optimized proximate and kinetics were later used to develop chicken nuggets with different percentages of mutton and fish liver added. The formulation was tested for the textural and organoleptic properties of value-added chicken nuggets that predict consumer acceptability. Comparative analysis of the variance between mutton and fish liver showed a highly significant (P<0.01) decrease in moisture, ash, protein, fat, DPPH, and TPC at different days and hours. The mutton liver had relatively high antioxidant potential (25.9% DPPH and 154-mg GAE/100 g TPC) compared with the fish liver. However, the fish liver’s FFA and POV (2.4% for both) were higher than those of the mutton liver. The results showed that, after formulation, an increase in the amount of liver led to a highly significant (P<0.01) rise in the nutritional value of the nuggets, including a 1.5%∼2.0% increase in protein content. This research indicates that valuing mutton and fish liver as a protein replacer in processed foods can be useful in developing healthy food products.

Formulation and Quality Evaluation of Chicken Nuggets Supplemented with Beef and Chicken Livers
Liaqat Mehmood,Syeda Afnan Mujahid,Sawera Asghar,Hafiz Ubaid ur Rahman,Nauman Khalid 한국축산식품학회 2024 한국축산식품학회지 Vol.44 No.3
This study explores the potential of utilizing meat byproducts, specifically chicken and beef liver, to enhance the nutritional value of processed foods like chicken nuggets. Proximate analysis was conducted on the livers, including moisture, ash, fat, and protein content, and degradation potential was observed. Antioxidant potential was analyzed through 2,2-diphenyl-1-picrylhydrazyl (DPPH). The total phenolic content (TPC), oxidative stability through peroxide value (POV), and free fatty acid (FFA) were performed to evaluate quality changes during seven-day storage. The radical scavenging activity showed that beef liver has excellent antioxidant capacity (61.55%- and 195.89- mM gallic acid equivalent for DPPH and TPC, respectively) compared to chicken liver and significantly increased the antioxidant potential of nuggets by 5%–10%. POV and FFA values increased with increased storage days for the liver and its incorporation in nuggets. However, the values remained under the 10 meq/kg threshold. Incorporating the livers into chicken nuggets led to a significant (p=0.000) improvement in nutritional content, particularly a 1.5%–2% increase in protein, with a similar increase in mineral content. Texture and sensory evaluations indicated favorable consumer acceptability for liver-enriched nuggets. Overall, this research shows the value of adding liver as a functional ingredient to enhance the nutritional profile of processed foods.
