Abstract

Starch is the most widely applicable food ingredient, offering innumerable applications in the
food industry due to its high technological value. The main purpose of this review is to gather
information from previous works on starch isolation and its characterization from different
food sources, such as cereals, tubers, fruits, and vegetables. However, challenges in starch
extraction, such as yield efficiency and purity, as well as the variations in properties
depending on the source, complicate the standardization of processes. Moreover, the effect of
various methods in improving starch, such as fermentation and microfluidization, has been
reviewed. Fermentation enhances properties like paste clarity, water absorption capacity, and
solubility of starch. Microfluidization improves the functional properties of starches by
applying high pressure, which may be beneficial for new product development. This review
contributes to understanding the advancements in starch modification techniques and their
potential to enhance product development in the food industry.

Ergonomic evaluation of occupational health hazards of farmers involved in sugarcane cultivation

By admin โ€” January 12, 2025

HTML Full Text PDF XML

Abstract

Sugarcane is a critical cash crop cultivated worldwide, with Brazil being the largest producer,
followed by India, China, and Thailand. However, workers in developing countries like India
face numerous work-related health issues, including ergonomic problems, occupational hazards,
and injuries. Sugarcane farming is labor-intensive, with harvesting identified as the most
hazardous activity. The repetitive movements and use of poorly designed tools during harvesting
often lead to frequent cuts, injuries, and musculoskeletal disorders. Farmers are also exposed to
high levels of toxic pesticides, resulting in respiratory issues such as coughing and chest pain.
This study systematically reviewed the ergonomic and occupational health hazards faced by
sugarcane farmers, analyzing 33 articles selected from an initial review of 88. Fifty-six articles
were excluded for various reasons. The findings emphasize the importance of ergonomic
interventions in reducing the physical demands of manual tasks and mitigating musculoskeletal
problems. Low-cost ergonomic solutions and awareness training programs were identified as
effective measures to improve farmers' working conditions and health outcomes. The study
concludes that ergonomic evaluations and targeted interventions are essential to preventing
injuries and musculoskeletal issues among sugarcane farmers. Future research should focus on
implementing and assessing these interventions to evaluate their long-term impact on farmers'
health and productivity. Despite the identification of several ergonomic hazards related to
sugarcane farming, the number of studies remains limited. This review provides valuable insights
to guide the development of regulations, tools, and strategies aimed at mitigating these risks and
improving the overall well-being of sugarcane farmers.

Comprehensive Analysis of Genetic variability, Trait interactions and Phenotypic diversity in Marigold (Tagetes spp.) genotypes

By admin โ€” January 10, 2025

HTML Full Text PDF XML

Abstract

Marigold (Tagetes spp.) is a popular ornamental plant known for its vibrant flowers. This
study evaluates genetic variability and correlation among key morphological traits affecting
flower yield in 38 marigold genotypes. Significant differences were observed across all traits,
indicating substantial variability within the genotypes while phenotypic coefficient of
variation exceeded genotypic coefficient of variation for all traits, suggesting environmental
influence on trait expression, though genetic factors remained dominant. Heritability
estimates were high for most traits, with number of ray florets per flower exhibiting highest
heritability (99.12%) coupled with highest genetic advance (121.24%), indicating that
selection for this trait is likely to result in substantial genetic improvement. Correlation
analysis revealed significant positive associations between flower yield per plant and traits
such as plant height (0.453), fresh flower weight (0.582), and number of flowers per plant
(0.414) at both genotypic and phenotypic levels. Path coefficient analysis highlighted fresh
flower weight and number of flowers per plant as key determinants of yield, with direct
positive effects of 1.267 and 0.988, respectively at genotypic level. Principal component
analysis identified first three principal components explaining 74.61% of total variability,
with days to flower initiation (PC-I), fresh flower weight and flower diameter (PC-II), and
number of flowers per plant (PC-II) contributing most to observed variation. The study
suggests that selection for these traits, especially fresh flower weight and number of flowers,
could significantly enhance marigold productivity in future crop improvement efforts. It
addresses complexity of trait interactions, offering key insights for genetic improvement.

Bioactive compounds and therapeutic properties of millet bran

By admin โ€” January 9, 2025

HTML Full Text PDF XML

Abstract

Millet bran is a by-product obtained during the processing of millet and is packed with a variety of nutrients. It is made up of the outer layer, seed coat, aleurone layer, a small part of the embryo, and the endosperm [1]. It makes up about 6โ€“8% of millet's total weight [2]. This by-product is typically thrown away during the milling and refining of cereal grains due to its appearance, taste, and ability to extend shelf life [3]. It contains bioactive elements such as fibers, lipids, proteins, and minerals [4]. Additionally, millet bran is higher in vitamins B, C, and E compared to the kernels [5,6]. Moreover, millet bran is a good source of phytochemicals, including flavonoids, polyphenols, phytosterols, dietary fiber, and other bioactive substances [4]. Beyond its high fiber content, millet bran is also a rich source of essential oils. The fat content of the millet small bran had unsaturated fatty acids, linoleic acid, linolenic acid, arachidonic acid and other essential fatty acids unsaturated fatty acids [7]. This review discusses the phytochemical potential of millet bran and provided valuable insights into these compounds and their possible therapeutic properties in disease management.

By admin โ€” January 8, 2025

HTML Full Text PDF XML

Abstract

The present study was conducted to assess the physico-biochemical variability in
seventeen genotypes, including the check variety SolanLalima, using a Randomized Complete
Block Design with three replications. The aim was to estimate variability, heritability, genetic
advance, correlation, and path coefficient analysis for yield and other horticultural traits. The
estimates of phenotypic and genotypic coefficients of variation (PCV and GCV) were high for
titratable acidity (31.96% and 31.08%). High heritability and genetic gain were observed for
titratable acidity (94.53% and 62.24%) and 100 seed weight (93.71% and 51.06%). Correlation
studies at genotypic and phenotypic levels revealed significant positive correlations between fruit
yield per plot and traits such as the number of clusters per plant, number of fruits per cluster,
average fruit weight, fruit width, fruit length, pericarp thickness, number of seeds per fruit, 100
seed weight, harvest duration, plant height, total soluble solids, and ascorbic acid. Path
coefficient analysis indicated that the number of clusters per plant (1.028) had the maximum
positive direct effect on fruit yield per plot, followed by 100 seed weight (0.719), number of
fruits per plant (0.741), average fruit weight (0.468), total soluble solids (0.416), fruit width
(0.275), pericarp thickness (0.252), days to 50% flowering (0.227), number of locules per fruit
(0.083), and harvest duration (0.013). Principal Component Analysis showed that the first four
principal components captured most of the dataset variance, emphasizing traits like average fruit
weight, fruit dimensions, plant height, and days to first flowering. This dimensionality reduction
simplifies data analysis and highlights critical patterns, providing valuable insights for future
crop improvement.

By admin โ€” January 7, 2025

HTML Full Text PDF XML

Abstract

The present study was conducted with the objectives to estimate genetic variability for
different characters, to estimate heritability, genetic advance as per cent of mean for
identification of promising genotypes suited for direct seeded and transplanted condition in
rice. As varietal development for direct seeded rice has been neglected which may explain
why it has not become popular such comparison were made on uncertain rainfall conditions.
Analysis of variance indicated that the mean square due to between family were highly
significant for all characters under study under direct seeded and transplanted condition,
which revealed presence of significant genetic variability between the families. Intra class
correlation lead the interference that differences between family is large and each family
differentiated distinctly from the other at higher level in F 5 generation. High genotypic and
phenotypic coefficient of variation was recorded for grain yield plant -1 (g) and moderate for
others under direct seeded condition and moderate GCV and PCV was recorded for grain
yield plant -1 and moderate for others in transplanted condition. High heritability coupled with
genetic advance as per cent of mean was recorded for days to 50% flowering, days to
maturity, number of panicles plant -1 , number of spikelets panicle -1 , plant height (cm), number
of filled grains panicle -1 , 1000 grain weight (g), grain yield plant -1 (g) and moderate for others
in direct seeded and transplanted condition. This study, between-family variance was
prioritized during selection to enhance genetic superiority in grain yield. Out of twenty-six
families derived from thirteen crosses, seven families under direct seeding and nine families
under transplanted condition exhibited superior yield traits compared to the check. Notably,
six families demonstrated consistent superiority across both conditions.

Assessment of cadmium bioremediation potential of fast-growing tree Melia dubia Cav.(Malabar Neem) in North Western Himalayas

By admin โ€” January 5, 2025

HTML Full Text PDF XML

Abstract

Cadmium (Cd) is recognized as highly toxic to humans and plants. Different methods, like
chemical, physical biological, and phytoremediation have been used for the remediation of Cd
contaminants from Urban and agricultural soil out of which phytoremediation is considered an
eco-friendly remediation of soil, often called green remediation. On a large scale,
phytoremediation using fast-growing trees may be preferred to annual/ biennial crops due to
their capacity to produce large biomass, extensive deep root system, and ability to accumulate
toxic metals in a form that is not biologically hazardous. The study aimed to evaluate different
varieties of Melia dubia (Malabar Neem) for phytoremediation of applied cadmium. The study
showed the significantly low effect of applied cadmium on vegetative growth parameters and
biomass of trees. Further data generated through this study shows that the accumulation of Cd in
plant parts in order roots > shoots > leaves in all the experimental varieties.
Novelty statement:
Fast-growing tree species are one of the most important points when considering the potential
tree for phytoremediation. Limited studies have been conducted to assess the cadmium
bioremediation potential of Melia dubia. This study was done to assess the bioremediation
potential of fast-growing, money-spinning trees which became popular amongst the farmers of
the country due to their multipurpose uses in wood industries and suitable trees in agroforestry
models wood industry. This study showed M. dubia can to be a good candidate for heavy metals
remediation for the industrial sites of the country specifically hill states due to its fast-growing
nature and heavy biomass production. Further, for effective bioremediation/ bioaccumulation of
heavy metals, planting of this tree species will provide a chance for rehabilitation and
improvement of heavy metals polluted sites.
