Apart from anthocyanins black carrot is also a good source of vitamin C and phenolic compounds which helps in enhancing the antioxidant potential of black carrots. For physical ailments consumption of black carrot extract has been reported since ancient times but it is not accepted as a vegetable for consumption. In North India black carrots are utilized for making a fermented drink which is rich nutritionally. Black carrot juice acidity, pH and total soluble solids was observed as 0.37%, 5.65 and 6.59° Brix, whereas kanji juice acidity, pH and total soluble solids was recorded as 0.47%, 3.02 and 3.87° Brix.

During the study, tomato crop was grown in an open field under five coloured-plastic mulching, one organic mulch and a no-mulch treatment. Harvested tomato fruits were analysed for various physico-chemical post-harvest quality parameters. Results evidenced that sphericity of tomatoe fruits was non-significantly (P<0.05) affected by mulching treatment. The highest fruit sphericity (0.96) was observed under yellow mulch followed by black (0.95). Likewise, average fruit weight (57.59 g) and lycopene content (2.99 mg/100 g) was found highest under red mulch. The highest TSS content (4.97) were reported in organic mulch followed by silver (4.90), while ascorbic acid content was highest under white mulch (32.7 mg/100 g) followed by organic mulch (30.9 mg/100g). Under black mulch, the highest levels of phenolic content (59.0 μg GAE/100 g) as well as antioxidant acti...

Hence, red capsicum pomace obtained as byproduct after EL was freeze dried to produce capsicum pomace powder (CP). CP had almost 80% of bioactives (total carotenoids 91.23 ± 2.35 mg/100 g) and antioxidant activity (DPPH 1.61 ± 0.12 µmol TE/g) compared to fresh pomace. CP was further used to develop muffins. Different concentrations (2-10%) of CP were mixed in wheat flour for preparation of muffins. Wheat flour was fortified with CP at different levels (2-10%) and subsequently, effect of CP fortification on height, texture, bioactives and sensory quality of muffins was observed. CP fortification improved the quality in terms of color, flavor and texture. During storage, hardness values (34.42-32.56 N) showed decreasing trend with increase in CP content. Overall, 6% CP fortification was found most acceptable...

Total soluble solids (TSS) and pH of untreated coriander paste was 7.8 and 6.21°brix, respectively. No significant (α = 0.05) difference was observed in pH or TSS after processing and during storage. Phenolic content increased by 0.99 and 1.10 % when treated at 400 and 600 MPa, respectively. Flavonoid content in high pressure (HP) processed (≥400 MPa) sample was significantly (α = 0.05) higher than thermally processed sample. The untreated coriander paste had ascorbic acid content of 1.32 mg/g which decreased to 1.17 and 0.50 mg/g on HP (600 MPa) and thermal processing, respectively. Chlorophyll a decreased from 1.68 mg/g to 1.58 and 1.21 mg/g in HP (600 MPa) and thermally processed sample, respectively. Complete enzyme [Polyphenol Oxidase (PPO) and Peroxidase (POD)] inactivation was observed after thermal processing, whereas pressure ≥400 MPa required to reduce enzyme activity significantly (α = 0.05). Lightness L* value decreased significantly (α = 0.05) with pressure. Total plate count reduced from 3.0 × 103 CFU/g to zero and 1 × 101 CFU/g in thermally and HP processed (600 MPa) samples, respectively. Storage study (at 4 °C for 45 days) showed that bioactive compounds and antioxidant activity in both thermally and HP processed samples decreased during storage, but this decrease was more severe in thermally processed samples. Thus, study reveals that HPP is more effective at ≥400 MPa, in terms of retention of bioactive compounds, than the thermal processing.

Nagmoti among the different growing conditions. Methods: Cherry tomato cv. Nagmoti were grown under different conditions as per standard agronomic practices and harvested fruits were were analyzed for physical, biochemical and postharvest quality parameters. Result: About 1.63-fold variation in total carotenoid and 1.39-fold variation in lycopene content was recorded among the different growing structures. Highest titratable acidity (0.118%) and total phenolic content (µg GAE/100g FW) was found in the shade net structures. The highest antioxidant activity was recorded in insect-proof net house (15.45 µmol trolox equiv. g-1) while the least was found in open field (12.04 µmol trolox equiv. g-1) condition. Walking tunnel followed by shade net and insect-proof net house was found best for the better accumulation of functional parameters.

Moisture content was found to have significant effect on the properties of both the varieties. Axial dimensions, sphericity and surface area of both varieties decreased with decrease in moisture content. The thousand grain mass, bulk density and angle of repose decreased from 27.83 to 19.72 g, 378 to 322 kg.m−3 and 48.54 to 30.06 degrees, respectively while true density and porosity increased from 1266 to 1298 kg.m−3 and 70.17 to 75.19%, respectively, with decrease in moisture content in PB1. In case of PB1121 variety, the corresponding values were 29.94 to 22.24 g, 464 to 429 kg.m−3, 36.06 to 28.06 degrees, 1366 to 1398 kg.m−3 and 60.03 to 69.31%, respectively. Terminal velocity and coefficient of friction decreased with decrease in moisture content, while hardness of paddy increased.

The equilibrium moisture content of the grain during water absorption varied from 48.24 to 55% (d.b.). Average critical moisture content of PB1121 for soaking during parboiling was 41.67% (d.b.). Average moisture diffusivity during water absorption process was 5.06x10−10 m2.s−1 and activation energy was 53.85 kJ.mol−1. Modelling of water absorption behaviour using Page model revealed that it ftted well at individual temperatures (R2>0.9). However, the Generalized Page model provided poor performance with R2 of 0.65, MSE 0.0018 and mean relative deviation modulus (% P) 48.02, whereas multi-layer perceptron neural network model ftted well with R2 =0.99, MSE =0.0013 and P =14.69%.

Herein, the objectives of the present preliminary investigation were to assess the impact of plastic film (black and silver) and organic (wheat straw) mulching on the different rhizosphere microbial population, plant growth, and mineral uptake in tomato crop. The measurement of rhizosphere microbial population and plant growth attributes was performed at the vegetative and reproductive growth stages of the tomato crop, while, mineral uptake analysis was carried out at the vegetative stage using the inductively coupled plasma optical emission spectrometry (ICP-OES). The result of experiments revealed that soil mulching favored microbial abundance in the crop rhizosphere, improved plant growth parameters and mineral uptake in tomato plants.
