Abstract
Ageing is an evolutionarily conserved and irreversible biological process in different species. Numerous studies have reported that taking medicine is an effective approach to slow ageing. Lemon extract (LE) is a natural extract of lemon fruit that contains a variety of bioactive phytochemicals. Various forms of LE have been shown to play a role in anti-ageing and improving ageing-related diseases. However, studies on the molecular mechanism of LE in Drosophila ageing have not been reported. In this study, we found that 0.05 g/L LE could significantly extend Drosophila lifespan and greatly improve antioxidative and anti-heat stress abilities. Furthermore, transcriptome and metabolome analyses of 10 d flies between the LE-fed and control groups suggested that the differentially expressed gene ppo1 (Prophenoloxidase 1) and metabolite L-DOPA (Levodopa) were co-enriched in the tyrosine metabolism pathway. Overall, our results indicate that affecting metabolism was the main reason for LE extending Drosophila lifespan.

Abstract
In recent times, cost effective synthesis of semiconductor materials has been a subject of concern for the day to today applications. In this work, novelty has been made on the facile synthesis of metal oxides (TiO2 and CeO2) and nanocomposites (TiO2-CeO2) through sol-gel and precipitation methods of imparting lemon extract. The synthesized materials behave as the functional catalysts which has been further carried out for the photocatalytic degradation against 2,4-Dichlorophenol (2,4-DCP). The materials are then valued for the structural and optical properties. The lemon extract used in synthesis has played a premier role in upgrading the charge carrier separation, bandgap, and size reduction of the composite system. Further, the CeO2 supported TiO2 sample acts as the better visible light catalyst, due to the prevention of aggregation and existence of line dislocation that supported to access the additional electron trap sites.

Abstract
Application of hydrocolloid based edible coatings is widely investigated as a promising means to retain quality and to extend the shelf life of food products. Present investigation was aimed to analyze influence of treatments, with different concentrations of lemon extract (0, 5, 10 and 15)% and coating with (0 and 5)% soy protein isolate (SPI), on fresh-cut melons. After the treatments, the samples were packed in polypropylene containers and kept at 4 °C for quality and shelf life analyses. The study involved 8 combinations of melon samples which were monitored in triplicate on specific days for different quality parameters including headspace gases, physicochemical, sensory and microbiological changes over the storage period. Lowest weight loss was indicated by samples treated with both lemon extract and soy protein isolate. When compared to control, coated samples indicated 4.36 log CFU/g lesser total plate count, and 2.39 log CFU/g lesser yeast and mold count at the completion of storage. Treatments showed effectiveness to retain vitamin C of melon samples. Total soluble solids, pH and titratable acidity varied remarkably through the storage life. Significant differences were observed in sensory attributes of control and coated samples. Chroma and color change (ΔE) values also reflected the potential of soy protein isolate coating to protect foods. Overall, the results suggested that lemon extract and soy protein isolate can help in retaining quality and extending the shelf life of fresh-cut melon.

Abstract
With increasing preference for all-natural foods to those involving synthetic chemicals, native isoelectrically precipitated soy protein isolate (SPI) was prepared using amaranth (Amaranthus tricolor L.) lye (pH > 12.5) and lemon extract, (pH < 2.5) as natural, food-plant-based chemicals. Protein content (91.21 %), yield (43.62 %) and digestibility correlation amino acid score (0.77) were obtained and were comparable to those of SPI prepared using synthetic chemicals (NaOH and HCl). Methionine and cystein-s were significantly higher in the natural SPI while glutamine and serine were higher in synthetic SPI (p < 0.01). Most of the determined minerals were higher in the natural SPI with potassium being the highest. Sodium was very high in the synthetic SPI. The rest of the minerals including phosphorus, iron and nickel, showed no significant difference. Anti-nutritional factors (trypsin inhibitors and phytic acid) were considerably lower in the natural SPI. Thus, a quality all-natural SPI can be produced using amaranth lye and lemon extract to address concerns regarding use of synthetic chemicals.
