Cold plasma is proven method of food preservation which control food spoilage at very lower temperatures. The prospective potential of cold plasma treatment to control the pulse beetle Callosobruchus chinensis L. infestation of chickpea for the storage period of about five years after plasma treatment was studied. Chickpea cultivars Vijay and Digvijay were used. Pulse beetle un-infested plasma untreated, pulse beetle un-infested plasma-treated, pulse beetle infested plasma untreated and pulse beetle infested plasma-treated samples studied for comparative pest status after every quarter. Cold plasma treatment at 40, 50, and 60 W power each for 10, 15, 20 min. was applied. The samples were stored in an airtight zip lock pouch under laboratory conditions. Cold plasma was f...

The knowledge, attitude, and practice of breastfeeding and infant feeding practices among mothers are important to prevent these comorbidities. Research aim(s)/question(s): The present study aimed -to assess the knowledge and practice of breastfeeding and infant feeding practices among mothers of different socio-economic status in a region of Delhi. Methods: The study was a cross sectional study conducted among postpartum mothers having children below 1.5 years. Results: Around 52% of the mothers were exclusively breastfeeding, 62% experienced skin-to-skin & breastfeeding within an hour after delivery. The majority of the mothers knew the importance of colostrum for their babies and were aware that no prelacteal feed was needed for the initial 6 months. There was an association between exclusive breastfeeding and mo...

The cookies prepared with four different composition i.e., Sample1 (control), Sample 2 (basil), Sample 3 (basil + ajwain), Sample 4 (basil + orange peel). Results interpret that incorporating basil, ajwain, and orange peel have an encouraging effect on the nutritional and elemental value of cookies compared to sample 1. Sample 1 contains a fair amount of carotenoid content, and the phenolic content was higher in sample 4, whereas chlorophyll content was higher in sample 3. In contrast, sample 2 contains the highest level of chlorophyll b and total chlorophyll. The samples containing basil were harder (398.49 ± 17.09), and fracture-ability was more in the control sample (657.98 ± 75.62), whereas gumminess was more in cookies prepared from basil + orange (180.64 ± 8.40). After control basil incorporated cookies showed better in color (7 ± 0.58), hardness (7.46 ± 0.78), taste (7.23 ± 0.44), mouth feel (7 ± 0.82), and overall acceptability (7.07 ± 0.73) compared to other cookies. Considering all the parameters in this study, cookies prepared with herb basil incorporation help improve the quality of cookies.
Intensification in synthesis of triglycerides of octanoic acid using a heterogeneous amberlyst-15... more Intensification in synthesis of triglycerides of octanoic acid using a heterogeneous amberlyst-15 catalyst has been investigated with the application of ultrasound under solvent-free conditions. Further, the frying characteristics of medium-chain triglycerides (tricaprin) are evaluated by deep frying of French fries in various combinations of palm oil and tricaprin. Understanding into the effect of parameters such as the temperature of the reaction (over the range of 40 °C–80 °C), loading of amberlyst-15 (1%–5%) and molar ratio of fatty acid to glycerol (3:1–3:5) along with the ultrasound conditions as duty cycle (40%–90%) and time on the conversion (%) has also been developed. Based on the outcomes of the study, optimum reaction conditions seen are 3:4 as the molar ratio of fatty acid (C8): glycerol, amberlyst-15 loading of 3% and a reaction temperature of 50 °C. It was further observed that the optimum ultrasound conditions required for maximum conversion of 99.8% were 240 W power, 80% duty cycle and 15 min as the ultrasound irradiation time. Under similar conditions, the conventional synthesis resulted in only 20% conversion in 15 min. Reusability studies also established that the acid–resin catalyst was effectively reused for 8 times. The PV, p-AV and TPC of frying oil combination containing higher tricaprin (50:50–palm oil: MCT) was 8.4 ± 0.8, 23.1 ± 0.01 and 29.8 ± 0.01 respectively, which were lowest as compared with other blends indicating the beneficial effects of MCT in frying applications. The work clearly shows that the ultrasound application for the synthesis of triglyceride of octanoic acid gives higher conversion (%) in a less time and also demonstrates that MCT could be a good alternative for deep frying of foods in combination with palm oil to enhance the shelf-life of food.

In present research outcome of various reaction parameters like reaction temperature, loading of catalyst and molar ratio of reactant on rate of conversion of reactant is studied. Further ultrasonic pre-treatment parameters like pre-treatment time and duty cycle are studied. During study it is established that the ideal reaction conditions for the maximum conversion of reactant were molar ratio of reactant i.e., glycerol: fatty acid as 5:3, reaction temperature of 140 °C, amberlyst-15 loading of 5%. It is also established that the pre-treatment time of 25 min and 80% duty cycle gave good results. Recyclability of amberlyst-15 is established for 15 cycles of esterification reaction. The study showed that the use of ultrasonic pre-treatment and amberlyst-15 as a catalyst have beneficial effect on rate of conversion of reactant and also have an effect on reduction in reaction time to 07 h as compared to conventional synthesis of triglycerides of hexanoic acid. Maximum conversion of 96% was obtained in 07 h with ultrasonic pre-treatment and amberlyst-15.

Effect of several reaction conditions like molar ratio, reaction temperature, and amberlyst-15 loading on the rate of conversion has been studied. Effect of ultrasonic conditions like duty cycle and irradiation time on the intensified synthesis is investigated. Recyclability of amberlyst-15 is studied to make process more economical. It is investigated that the optimum reaction conditions which gave maximum conversion of 95% were molar ratio of capric acid: glycerol as 3:5, reaction temperature 90oC, 4% amberlyst -15 loading. It was further investigated that ultrasonic conditions which gave intensified synthesis were 70% duty cycle and irradiation time of 120 minutes. The ultrasonic assisted process was compared with conventional synthesis. Conventional synthesis gave 30% yield in 120 minutes and 82% in 18 hours. Amberlyst-15 was successfully reused for 13 cycle without any change in the conversion (%) of reaction.
