Physical, Functional and nutritional quality characterization of microencapsulated Ber (Ziziphus mauritiana L.) fruit powder
Limited availability, lower shelf life, and lack of suitable technologies are major drawbacks for the limited utilization of Ziziphus fruit in processing industry. This study was carried out with the aim to enhance the shelf-life and retain the economic importance of Ziziphus by using spray drying process for Ziziphus powder production. Maltodextrin used as wall material in different concentrations and inlet air temperature were taken as independent variables to study their effect on major powder responses i.e., powder yield, water activity, color properties, vitamin-C, total flavonoid content, and total antioxidant activity. Lower encapsulant quantity (10-15%) was inefficient in limiting the degrading impact of temperature on bioactive compounds. Higher encapsulant quantity of 25% had masking effect on bioactives concentration and their associated activity retention. Therefore, 170°C inlet air temperature, 20% maltodextrin concentration and 60ml/h feed flow rate were optimized to obtain 22.30 ± 3.09% for producing commercially viable powder with lowest water activity (0.295 ± 0.02), best color retention (L* 88.52 ± 0.70, a* 1.13 ± 0.49, b* 12.25 ± 0.62), highest bioactive retention (vitamin C 14.56 ± 0.59 mg/100g, flavonoid content 388.00 ± 0.46 mg/100g) and associated functional activity (antioxidant activity 1.89 ± 0.56 to 2.10 ± 0.50/g).
EFFECT OF MULCHING PRACTICES, VARIETIES AND FERTILITY LEVELS ON PHYSIOLOGICAL GROWTH PARAMETERS OF CLUSTERBEAN
A field experiment was conducted during the kharif season of 2013 and 2014 to evaluate the effect of mulching practices, varieties and fertility levels on physiological parameters of clusterbean at the Research Farm, College of Agriculture, Gwalior. The results revealed mulching practices, varieties and fertility levels on physiological parameters of clusterbean that increased the value of CGR, AGR and LAI up to 90 DAS, RGR up to 60 DAS and LAR up to 30 DAS growth stage and then decline up to maturity. The values of dry matter, CGR, RGR, AGR and leaf area index were recorded higher with plastic mulch, HG-563 and 75% RDF +VC 5t/ha. over remaining mulch, varieties and fertility levels. While leaf area ratio (LAR) was recorded maximum in Control (N0P0K0) over other fertility levels at all growth stages.
Differential varietal reaction of Macrophomina phaseolina incitant of charcoal rot disease
Charcoal rot incited by Macrophomina phaseolina is an economically important disease of sesame. Sesame is one of the important oilseed crops and high valued due to nutritional and medicinal properties. Weather variables predisposed M. Phaseolina for quantification of disease progression at different rate and differential reaction on sesame varieties. Differential reaction of M. phaseolina on sesame varieties was studied during three different dates of sowing. Progression of disease was found highest during period of 18th August and 23rd August in all dates of sowing. Maximum disease incidence was recorded in early sown crop followed by mid and late sown conditions. Higher charcoal rot disease incidence was recorded in variety HT1 than HT2 during different dates of sowing. The progression of charcoal rot disease over a time was assessed by area under disease progress curve. Area under disease progress was recorded higher in variety HT1 than HT2 in all three different dates of sowing. It was observed maximum during early date of sowing followed by mid and late sown conditions.
Determination of Drying kinetics and Cellulose content of Punica Granatum L. Peels
The pomegranate tree, scientifically known as Punica granatum L., belongs to the Punicaceae family and yields a fruit widely consumed for its traditional and medicinal properties. Peels of pomegranate are highly nutritios but go waste and unutilized. So, a study was conducted to determine the drying kinetics and cellulose content of Punica Granatum L. Peels. Page model was used for drying kinetics. It was found suitable for the three drying temperatures viz. 50, 60 and 70°C, respectively. Page model parameters n, ln K and co efficient of determination (R2) at 50, 60 and 70°C ranged from -0.415 to -0.490, 2.222 to 2.352 and 0.979 to 0.987, respectively. the surface area (s) and volume (v) of the peel slices were calculated to be 3 mm² and 1.5 mm³, respectively. The moisture diffusivity (D) value at drying temperatures of 50 °C, 60 °C and 70 °C was found to be 2.73 × 10-3 m2/s, 3.16 × 10-3 m2/s and 5.25 × 10-3 m2/s respectively. Activation energy (Ea) of the peel can be was found to be 39 kJ/mol. Cellulose content 50, 60 and 70°C varied from 542 to 695 mg/100g.
Molecular Characterization and Cross-Pathogenicity Assessment of Black Rot (Xanthomonas campestris pv. campestris) Strains in cabbage, broccoli, radish, mustard, cauliflower and Knolkhol from Meghalaya
The present study aimed to isolate and characterize the black rot pathogen, Xanthomonas campestris pv. campestris (Xcc), from cabbage, broccoli, radish, mustard, cauliflower and Knolkhol in the EKH district of Meghalaya, India. A total of 20 isolates were obtained, and 16 of these were confirmed to be pathogenic based on the development of characteristic "V-shaped" lesions. From these 16 isolates, 6 were selected from each crucifers’ strains for further biochemical and molecular studies. Microscopic and cultural studies revealed that all 6 isolates were gram-negative, rod-shaped bacteria with circular colonies. However, variations in texture, margin, consistency, color, and growth pattern were observed among the isolates. For instance, isolate XC CAB4 exhibited a smooth texture, lobate margin, slimy consistency, and pale-yellow color, while isolate XC CALI1 had a less smooth texture, an entire margin, a more slimy and less glistening consistency, and a deep yellow color. Biochemical tests showed that all 6 isolates were positive for H2S production, starch hydrolysis, gelatin liquefaction, and ammonia production, but negative for indole production, casein hydrolysis, Voge's Proskauer test, and methyl red test. The isolates were further confirmed as Xcc by amplifying the hrp F gene using specific primers, and a phylogenetic tree was constructed to compare the isolates with other representative strains. Cross-pathogenicity and aggressiveness assays revealed that all 6 isolates were capable of infecting different cruciferous crops, with varying infection rates and progression of black rot disease. The area under the disease progress curve (AUDPC) was calculated for each isolate, with XC BRO1, XC CALI1, and XC MSD2 showing higher AUDPC values, indicating greater aggressiveness in causing black rot disease on cabbage leaves compared to XC CAB4, XC RAD2, and XC KNKH1.These findings enhance our comprehension of the virulence of various Xcc isolates from cruciferous crops in Meghalaya. This understanding can aid in screening and developing cruciferous cultivars that are resistant to Xcc, predicting disease outbreaks, and evaluating the risk of crop damage. It also aids in the development of effective strategies for managing black rot disease in cruciferous crops.
