The effect of microwave heating on the physicochemical and microbiological quality of Raw milk
Milk and dairy products are among the most popular foods worldwide, especially for infants, and microwave usage in food preparation, particularly for milk, has become increasingly common. Therefore, the objective of this study is to assess the effect of microwaves on the physicochemical and microbiological properties of Raw milk, particularly focusing on mineral content to evaluate milk quality. The results obtained showed that the average fat, protein, lactose, and dry matter content decreased during microwave exposure, especially at 2 minutes, while acidity increased slightly. In contrast, minerals such as calcium, magnesium, and phosphorus remained stable even after 2 minutes of heating. We conclude that physicochemical and microbiological parameters are sensitive indicators of milk quality.
Nourishing the Future: Assessing Progress, Challenges, and Policy Initiatives for Millet Revival in India
Millets are considered superfoods due to the number of benefits they provide to humans. For smallholder and marginal farmers, millets offer economic stability due to their low input costs and adaptability to different ecological zones. The revival and promotion of millets can lead to increased biodiversity, and by tapping into the growing market for nutritious and health-conscious foods, farmers can achieve higher economic returns. Millets can enhance national and global food security by diversifying food sources beyond the major cereals. The progress and trend analysis of important millets such as Sorghum, Bajra, Ragi, and small millets is made in the study. It is found that the compound annual growth rate (CAGR) from 2011-12 to 2021-22 for the area under Finger Millet (Ragi) is positive, which is 0.29 percent, while it is negative for Sorghum, Bajra, small millets, and total millets. From the trend analysis of the available data from 2011–12 to 2021–22, it is found that due to competition from other crops, the area will fall continuously. In trend analysis, from 2022–23 to 2029–30, in Bajra, the production will range from 99.25 lakh tons in 2022–23 to 104.76 lakh tons in 2029–30. While the production will fall for all other millets in the given period. Millets face a number of challenges, such as low yields, low input crops, low demand, and less awareness about their benefits. However, sincere efforts are made by the government in the form of new schemes, concessions, awareness programmes, trade, and research support to increase the area and productivity of millets. One such significant effort is the declaration of 2023 as the International Year of Millets. Such promotional support will certainly increase the area and production of millets in India.
Evaluation of salt tolerance mechanism in different cultivars of wheat Triticum aestivum at the seedling stage
the most important constraints for crop production worldwide. Salinity stress negatively affects the growth and development of wheat leading to reduced grain yield and quality. To address these issues a study was planned to assess the salt tolerance mechanism using physiological (shoot and root length, fresh weight, chlorophyll content) biochemical and molecular-related parameters in four wheat varieties, two tolerant and two sensitive. Wheat seedlings were subjected to three increasing concentrations of salinity stress [(C) 0mM, (T1) 50mM, (T2) 100mM, (T3) 150mM] using NaCl under hydroponic conditions for 21 days. Tolerant wheat genotypes had higher fresh weight and chlorophyll content as compared to sensitive under salt stress. Antioxidant parameters such as hydrogen peroxide (H2O2), malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) were estimated both in shoot as well as root tissue. Tolerant wheat genotypes induced the antioxidant enzymes CAT and APX more efficiently and hence were more tolerant to the antioxidant stress in the form of H2O2 and MDA. NHK1 and HKT1 genes demonstrated higher expression levels in tolerant varieties. Similarly, proline biosynthesis gene demonstrated enhanced activity in tolerant varieties. The study provides insight into the role of NHX1, HKT1, and P5CS genes in salinity tolerance and their utility as biomarkers for reliable screening for salt tolerance at the seedling stage in wheat genotypes.
Evaluation of the antioxidant activity of the Ephedra alata species
Ephedra alata is an endemic Algerian plant with pharmacological potential, used for centuries in traditional medicine. Herein the antioxidant activity of E. alata was assessed in order to validate its traditional use in Algerian folk medicine for the treatment of different aliments. The antioxidant activity of its aqueous extract was evaluated by different assays including, DPPH, reducing capacity, and β-Carotene Bleaching Assays. E. alata aqueous extract seems to have moderate reducing capacity with EC50 of 578,16 μg/mL, and an average scavenging effects with respect to the DPPH radical with IC50 of the order of 276 μg/mL. However, we found that aqueous extract of E. alata possess a remarkable antioxidant activity against the bleaching of β carotene (77%). These results suggest that the extract of E. alata has a considerable capacity to react with free radicals to convert them into non-reactive species and to interrupt the chain of radical reactions. It also reflects the solubility of the antioxidant compounds of the extract in water. Compounds that possess this characteristic can be used in food systems. Obtained results suggest that aqueous extract of Ephedra alata could provide powerful natural; antioxidant, agents, to be used in the management.
Isolation identification and histopathological examination of Pasteurella infection in Respiratory tract of slaughtered Buffalo in Unnao and Barabanki District of Uttar Pradesh
In order to investigate the bacteriological infection in the respiratory tract, lung lesions were examined in 34 patients (37.77%) from Unnao and 26 cases (28.88%) from Barabanki districts. The identification of thirty-four isolates as Pasteurella spp. was based on their morphology, cultural/colony characteristics, and biochemical properties, such as the production of catalase, urea hydrolysis, citrate consumption, and indole. In Unnao and Barabanki district, emphysematous lung was found in 8 cases (8.88%) and 6 cases (6.66%) of lung lesions, respectively, and congestion with hemorrhagic lesions in 14 cases (15.55%) and 11 cases (12.22%). The lung slaughtered in Unnao and Barabanki district showed two cases (2.22%) of hard nodular growth/granulomatous lesions and one case (1.11%) of nodular lesions. The percentage of cases in each district that had pulmonary oedema was 6 (6.66%) and 5 (5.55%). In both districts during the study period, the highest number of cases of lung congestion and hemorrhages were followed by emphysematous conditions and pulmonary oedema in the slaughtered animal. Microscopic views show that significant emphysema can occasionally be observed in addition to vascular and bronchiolar congestion. The lungs grossly characterized as having pulmonary emphysema upon histopathological investigation showed blood vessel congestion, ruptured alveoli resulting in the creation of giant alveoli. Tissue sections were also stained using the MacCallum-Goodpasture staining procedure in order to demonstrate the organisms, and twenty lung tissues were found to have red coccobaccilli organisms. In pneumonic lungs, mild to moderate fibrosis was seen. Mallory Heidenhain and Masson's trichome staining revealed fibrous tissue as blue. Therefore, because of pasteurellosis, unwell buffaloes are killed in slaughterhouses for human consumption; the flesh from these animals should not be eaten or may be declared ineligible due to illnesses.
