An experiment was carried out to investigate the effect of prepared chitosan: pullulan (50:50) blend edible coating enriched with pomegranate peel extract on the quality, sensory attributes and shelf life of litchi fruit cv. Deshi throughout the 18 days storage period at room (23 ± 3ºC, RH-40-45%) and cold (4 ± 3ºC, RH-90-95%) temperature. The recorded results revealed that the application of chitosan:pullulan (50:50) blend edible coating exhibited significantly reduce the increasing physiological weight loss, TSS, acidity and browning (color) of litchi fruits during storage as compared to control litchi. Whereas the treated fruit showed lower decreasing weight loss at room (44.49 ± 0.30%) and 4ºC (10.41 ± 0.16%) temperature as compared to control litchi on 18 th days of storage. Increasing TSS & TA, decreasing pH, phenolic, flavonoid and antioxidant activity were control by the treatment of edible coating. The sensory characteristics were recorded higher in treated litchi fruits on 9 th days of storage period at both storage conditions. The results of the sensory evaluation confirmed that the treatment of chitosan:pullulan blend edible coating could be effective to prolong the shelf life of litchi at both storage condition. Paired "t" test was used to the comparison between the control and treated litchi for both room and cold storage. Significance difference (P ≤ 0.05) and correlation was analyzed between the control and coated samples of litchi fruit during the storage period. Further study should be needed to evaluate the effect of chitosan and pullulan blend edible coating on other fruits and vegetables.

The present work was undertaken with an objective to evaluate the impact of temperature on respiration rate of fresh black carrot using a non-linear enzyme kinetics approach. Two different models viz. Arrhenius equation (temperature effect) and enzyme kinetics (effect of temperature and headspace concentration) have been compared for predicting the respiration rate of black carrot. The respiratory behavior of black carrot was assessed using closed system technique at 5, 10 and 15 °C (± 1 °C) temperature and constant relative humidity (RH) of 85%. The O 2 consumption and CO 2 evolution rate values were 39.17, 58.88 and 68.08 ml kg -1 h -1 ; 22.15, 34.63 and 41.86 ml kg -1 h -1 after the attainment of steady-state condition at 5, 10 and 15 °C, respectively. The inhibition by evolved CO 2 was found to be predominantly competitive at all temperatures. The average absolute deviation in O 2 consumption and CO 2 evolution rate for Arrhenius model was 3.5% and 5.3% while for enzyme kinetics model was 8.8% and 6.3%, respectively. Dependency of respiration rate of black carrot on temperature was well defined by Arrhenius model. The outcomes of the study can be further utilized to design the MAP (modified atmosphere packages) for fresh black carrot storage at 5 °C with 85% RH.

Quick industrialization and growing the urbanization besides automatic undeveloped give achieve up to a lofty call of energy in every one of forms such as thermal, electrical and mechanical. To minimum acceleration energy is accomplished by burning of fossils fuels like coal; lubricate which further leads to its overexploitation in unsustainable conduct. The overuse of fossils fuels has increased environmental turbulence leading to serious detrimental effects such as large scale climate changes and global warming. This further leads to a shortage of any permanent source and thereby increasing the imports of the fuels. But we are so expedient to have some sustainable and ecological forms of energy for example-biomass, solar and, etc. Due to its everlasting characteristics and availability make it a better alternative for the present and future. Due to increasing environmental pollution, the researches emphasized supplementary on the making of biogas and bio-CNG from paddy straw. Producing renewable energy from paddy straw helps to lessen the energy catastrophe and paddy straw management, which is completed by anaerobic digestion. The future lies in the conversion of paddy straw into biogas. Keeping efficient management and conversion of paddy straw in mind Biogas or Bio-CNG production is the best possible method to obtain the clean low-carbon output. Biogas or bio-CNG obtained by anaerobic absorption of paddy straw tin be old as an energy cause for a choice of application namely, heating, cooling, brake cooling, electricity age bracket and gaseous fuel for vehicular applications. Paddy straw has immense economic value in the form of fresh gas production. This paper focuses on the review of exploring the most promising alternatives of paddy straw management and transmutation of biogas to bio-CNG to mitigate environmental pollution.
