Extraction optimisation and characterisation of Artocarpus integer peel pectin by malonic acid-based deep eutectic solvents using response surface methodology

Traditional pectin extraction methods involve strong acids, which are environmentally harmful. This study explores an innovative approach using Malonic Acid (MA)-based Deep Eutectic Solvents (DES) to extract pectin from Artocarpus integer Peel (AIPP), optimised through Response Surface Methodology (RSM). The extracted AIPP-A and AIPP-B from ChCl-MA and ChDHCit-MA DES, respectively, were characterised for yield, pH, solubility, Degree of Esterification (DE), Water and Oil Holding Capacity (WHC and OHC). The experimental values aligned with RSM model predictions, with low standard deviations: 0.7300 for ChCl-MA and 0.1531 for ChDHCit-MA. Optimal extraction conditions for AIPP-A were 3.27 % ChCl-MA, 1.28 h extraction time, 50.44 °C temperature, and a 1:40 g/mL solid-to-liquid ratio. For AIPP-B, the conditions were 4.95 % ChDHCit-MA, 2.04 h extraction time, 79.65 °C temperature, and a 1:50 g/mL solid-to-liquid ratio. ChCl-MA yielded 30.97 % AIPP, which was higher than that of ChDHCit-MA (27.99 %). Both AIPP demonstrated desirable properties such as low pH, high solubility, and significant DE. AIPP-A exhibited a greater DE (58.40 %) compared to AIPP-B (32.4 %) contributed to its lower WHC and higher OHC. In conclusion, RSM-based optimisation of AIPP extraction with DES is effective in producing pectin that is suitable for use as a gelling agent, preservative, and stabiliser in the food industry.

Effect of Different Approaches of Nutrient Application on Soil Quality Index Under Maize-Wheat Cropping System in Mollisol Region of Uttarakhand

ABSTRACT A field experiment was conducted at GBPUA&T, Pantnagar, to study the effect of different approaches of nutrient application on soil fertility and soil quality under maize-wheat cropping system. Nine treatment combinations were compared namely, Recommended Doses of Fertilizers (RDF), Soil Test Crop Response (STCR), and various combinations of organic and inorganic fertilizers. This paper aims to develop Soil Quality Index (SQI) based on Minimum Data Set (MDS) using Principal Component Analysis (PCA). Different indicators were employed to formulate the SQI, derived from surface soil layer measurements (0–15 cm). Each MDS indicator was then converted into a dimensionless score using linear scoring function and then integrated into SQI. Results showed that the key soil quality indicators identified as MDS using PCA under maize-wheat cropping system were Water Holding Capacity, organic carbon, available N and dehydrogenase activity. These soil quality indicators were found to be best for monitoring soil health status. After rabi wheat 2019–2020, SQI varied from 1.22 to 2.21 across the treatments whereas, after rabi wheat 2020–2021, SQI varied from 1.13 to 2.23 across the treatments. Among different approaches of nutrient application, STCR-based use of fertilizers along with FYM (T4) helped in maintaining better soil physical, chemical and biological properties and ultimately sustaining soil quality, which was followed by the treatment receiving 75% STCR dose of N (inorganic mode) + full P and K (T5). Integration of organics with inorganic fertilizers maintained soil quality, environmental health and reduced greater dependency on chemical fertilizers.

Modeling hydrogeological conditions of noble gases in water and aqueous electrolyte solutions

Dissolved noble gases in water hold significant potential as tracers and precursors in various hydrogeological and geological applications, particularly in understanding surface water-groundwater interactions. These applications necessitate precise solubility predictions. Employing the fugacity-fugacity approach, our study models the solubilities of Neon, Argon, Krypton, Xenon, and Radon in both pure water and electrolyte solutions. Leveraging the Cubic-Plus-Association Equation of State, we achieve remarkable accuracy, with average deviations below 2.5 % for vapor pressure, liquid, and vapor-phase densities. Additionally, in water–gas binary systems, deviations in gas solubilities within pure water remain under 5.0 %. Extending our analysis to water–gas-salt ternary systems, our model demonstrates deviations smaller than 5.6 %. Alongside discussing the gas dissolution mechanism, this work emphasizes the adaptability of the model, informed by robust experimental and modeling data. The interpretations derived from modeling hydrogeological conditions are poised to enhance our understanding of hydrological processes, thereby assisting planners and water managers in achieving sustainable development and management of water resources.

Physicochemical Properties and Microstructure of Mixed-species Surimi Made from Decapterus sp. and Priacanthus sp.

The surimi industry plays a substantial role in bolstering Indonesia’s fishing sector. The collapse of the majority of surimi companies can be attributed to the government limitation on trawling, which served as the primary source of demersal fish utilized in surimi processing. This restriction resulted in a significant shortage of raw material for industry. Therefore, it is imperative to explore alternate fish species that can serve as viable raw materials for the production of surimi. Alternative fish species are needed as raw materials for surimi. The objective of this work was to investigate the physicochemical characteristics and microstructure of surimi produced from two distinct Indonesian fish species: Decapterus sp., a pelagic species, and Priacanthus sp., a demersal species. Five ratios of Decapterus sp and Priacanthus sp; 1:0 (F1: control 1), 3:1 (F2), 1:1 (F3), 1:3 (F4), and 0:1 (F5: control 2) were tested. The proximate composition showed that the addition of Decapterus sp. to the formula increased the protein and fat content of mixed surimi. The formula F4 showed the highest value for almost all textural profile parameters; there were springiness, cohesiveness, gumminess, chewiness, and resilience. The same result also presented in the gel strength, F4 also has the highest value. The Water Holding Capacity value was low, and it showed no difference between all formulas. The whiteness value was in the range of 66-68, and it showed no difference between all formulas. Protein patterns showed no myosin heavy chain in all formulas. Microstructure analysis showed that only F5 (control 2) was compact and denser, but the other formulas (F1, F2, F3, and F4) showed a large number of loose and porous structures. In the microbial analysis, all formulas showed the Total Plate Count value ( 6 x 105 cfu/g) was under the maximum acceptable value (107 cfu/g). The findings of the study indicated that the mixed-surimi, consisting of Decapterus sp and Priacanthus sp at a ratio of 1:3, exhibited the highest level of gel strength. In conclusion, Decapterus sp has the potential to serve as a viable raw material when combined with Priacanthus sp.

Thermoformed products from high-density polyethylene and Softwood kraft pulp.

Plastic recycling, waste minimization such as process outfall valorization promotes a circular economy. Herein, food trays have been produced in the moulded pulp thermoforming process. To this end, high-density polyethylene (HDPE) outfall has been dispersed in water via Poly vinyl alcohol (PVA) addition in a Northern Bleached Softwood KraftPulp (NBSKP) slurry. Samples physical and mechanical properties have been evaluated. With an increasing HDPE content, parts air permeability was drastically reduced to a minimum of 2.4±0.8 mL min-1. In addition, water and grease hold out properties have been increased with minimum waterCobb1800 value of 10.9±5.4 gm-2 and oil Cobb1800 value of13.18±6.5 gm-2. Samples with high HDPE content demonstrated hydrophobic surface with water contact angle value above 90°. HDPE melting and binding to wood pulp fibers was monitored by SEM images. Regarding the mechanical properties, HDPE induced plastic deformation with a reduced Young modulus by 17 %. Moreover, the addition of HDPE increased wet strength by 81 %. However, the produced foodtray composites with high HDPE content demonstrated low repulpability index.

Analysis of Soil Samples for its Physicochemical Parameters of Soil in Bawal Block of Haryana

Without a question, the oldest occupation on Earth is agriculture. The soil was virgin in the early stages of evolution, and farming was done very differently than it is now. Growing more food in a less amount of space has made it necessary to plant more crops more frequently and to use omnicides and fertilizers frequently. Excessive use of fertilizers and omnicides negatively impacts soil characteristics, air and water pollution levels. The study of agricultural science or soil science has piqued people's curiosity. An attempt has been made to address the aforementioned issues in this work. The soil in the area being studied has been physicochemical characterized. Key Words: Water Holding Capacity, High-performance Liquid Chromatography, Nutritive index, Fertility index

Intensive ammonium fertilizer addition activates iron and carbon conversion coupled cadmium redistribution in a paddy soil under gradient redox conditions

While over-fertilization and nitrogen deposition can lead to the enrichment of nitrogen in soil, its effects on heavy metal fractions under gradient moisture conditions remains unclear. Here, the effect of intensive ammonium (NH4+) addition on the conversion and interaction of cadmium (Cd), iron (Fe) and carbon (C) was studied. At relatively low (30–80 %) water hold capacity (WHC) NH4+ application increased the carbonate bound Cd fraction (F2Cd), while at relatively high (80–100 %) WHC NH4+ application increased the organic matter bound Cd fraction (F4Cd). Iron‑manganese oxide bound Cd fractions (F3Cd) and oxalate-Fe decreased, but DCB-Fe increased in NH4+ treatments, indicating that amorphous Fe was the main carrier of F3Cd. The variations in F1Cd and F4Cd observed under the 100–30-100 % WHC treatment were similar to those observed under low moisture conditions (30–60 % WHC). The C=O/C-H ratio of organic matter in soil decreased under the 30–60 % WHC treatment, but increased under the 80–100 % WHC treatment, which was the dominant factor influencing F4Cd changes. The conversion of NH4+ declined with increasing soil moisture content, and the impact on oxalate-Fe was greater at 30–60 % WHC than at 80–100 % WHC. Correspondingly, genetic analysis showed the effect of NH4+ on Fe and C metabolism at 30–60 % WHC was greater than at 80–100 % WHC. Specifically, NH4+ treatment enhanced the expression of genes encoding extracellular Fe complexation (siderophore) at 30–80 % WHC, while inhibiting genes encoding Fe transmembrane transport at 30–60 % WHC, indicating that siderophores simultaneously facilitated Cd detoxification and Fe complexation. Furthermore, biosynthesis of sesquiterpenoid, steroid, butirosin and neomycin was significantly correlated with F4Cd, while glycosaminoglycan degradation metabolism and assimilatory nitrate reduction was significantly correlated with F2Cd. Overall, this study gives a more comprehensive insight into the effect of NH4+ on activated Fe and C conversion on soil Cd redistribution under gradient moisture conditions.

The Potential of Weissella confusa K2 Isolated from Longan (Dimocarpus longan) Fruit as High Exopolysaccharide-Producing Strain

Isolation of Lactic Acid Bacteria (LAB) from various sources has previously been carried out to obtain strains that produce high of exopolysaccharide (EPS). Isolate K2, which was LAB isolated from longan (Dimocarpus longan) fruit, can produce EPS. This study aimed to identify isolate K2, and evaluated the effect of supplementation carbon sources (glucose, fructose, sucrose, and lactose) and pH of media (4, 5, 6, 7, and 8) on EPS production. Isolate K2 was identified as Weissella confusa molecularly based on 16S rDNA, the type of carbon source, and the pH of media had significant effects (P<0.05) on EPS production. W. confusa K2 produced EPS that was highest on media with the supplementation of sucrose as a carbon source and produced the lowest EPS on lactose. The amount of EPS produced by W. confusa K2 under alkaline was higher than under acidic, the highest EPS of 47.703 g/L at pH 8 and the lowest EPS at pH 4 of 1.858 g/L. The physical properties showed EPS has good solubility in water with the solubility and Water Holding Capacity (WHC) at 40.533% and 354% respectively. Based on Surface morphology of EPS with Scanning Electron Microscope (SEM) analysis, the surface structure of EPS was a porous polymer matrix. Fourier Transform Infrared Spectrophotometer (FTIR) results of EPS showed the presence of absorption bands as characteristic of carbohydrates, such as the presence of O-H, C-H, C=O, C=C, C-O-C groups, and glycosidic bonds.

A Simple, Affordable, Do-It-Yourself Method for Measuring Soil Maximum Water Holding Capacity

ABSTRACT There is an increasing need for accessible methods to monitor soil health. Our primary objective was to evaluate an accessible, do-it-yourself method for measuring the maximum water holding capacity – we call this the funnel, filter paper, and drainage (MWHCFFPD) method. First, we compared MWHCFFPD to the water desorption method via pressure cells (WHCPC), routinely used for generating soil water retention curves, using 10 soils from a wide range of textures (4–55% clay). Second, we tested the sensitivity of the MWHCFFPD to methodological variations likely encountered by citizen scientists. The two methods were quite comparable in precision, with mean coefficient of variances of 3.5% and 4.4% for the FFPD and water desorption method, respectively. The MWHCFFPD and WHCPC methods were comparable, with MWHCFFPD best correlating to WHCPC at −2.45 kPa (R2 = 0.98). The MWHCFFPD method is somewhat sensitive to some methodological modifications, most notably variation in water source, but with standardized protocols could be scientifically robust. Overall, MWHCFFPD can be used as a simple and affordable test of sieved soil structure and organic matter, and thus has potential to expand soil health monitoring.

Fee for Reducing Natural Field Retention as an Instrument of Sustainable Public Finance

Theoretical background: Active national fiscal policy is an important determinant of sustainable development. Poland falls below the water security level, which is why natural retention is a particularly important issue, as the poverty of societies begins with a lack of access to water. This also poses a challenge for public finance, which should encourage specific behaviors. As of 1 January 2018, a fee for the reduction of natural land retention is levied in Poland. Purpose of the article: The aim of the article is to analyze and evaluate the fee for reducing natural field retention as an instrument of sustainable public finance and to assess its fiscal efficiency in terms of its ability to raise public revenue, in particular the revenue of municipalities on the example of cities with county rights in the Silesian Voivodeship. Research methods: The paper draws on literature reviews and the conducted empirical research. Data were collected using the direct method via access to public information. First, an analysis was carried out on the amount of revenue generated from the fee for reducing natural field retention, constituting the income of the State Water Holding – Polish Waters. Subsequently, an analysis was made on the amount of revenue generated from the fee for reducing natural field retention in municipalities with county rights in the Silesian Voivodeship. The study covered the years 2018–2022, i.e. from the introduction of the fee until the last year for which the data are available. Main findings: The fee for reducing natural field retention is a sustainable public finance instrument designed to shape attitudes and influence behavior. Although levying a fee for reducing natural field retention does not solve the problem of insufficient retention, it encourages discussion and implementation of measures to improve it. The mandatory fee is intended to discourage the construction of impervious surfaces and, at the same time, encourage property owners to incorporate retention systems into their construction plans to counteract the lowering of groundwater levels. It is of great importance, not in an economic or fiscal sense (public revenue), but rather in a social sense, by raising public awareness of the problem of natural retention.

T3 treatment was the best on other locally extracted aloe vera oil treatments.

Effect of low-intensity ultrasound-assisted washing on biochemical and gelling properties of surimi from yellowstripe scad

Ultrasound-assisted washing had an expectant to increase the concentration of myofibrillar proteins that play an important role in gelling properties of surimi. This work investigated the effect of low-intensity ultrasound-assisted washing on surimi's biochemical and gelling properties from yellowstripe scad. Washed minced fish was obtained by conventional method or washing process through ultrasound at a frequency of 45 kHz with different steps. Physicochemical properties and protein patterns of washed minced and surimi gel were evaluated. Results showed that the washed minced fish treated by ultrasound three times (U-3) showed the highest L* (50.37 ± 0.23) and whiteness (48.69 ± 0.23) (p < 0.05). The ultrasound washing process significantly reduced total myoglobin content (from 2.790 ± 0.078 to 0.178 ± 0.029 mg/g) (p < 0.05). An increase in oxymyoglobin content was found in minced fish treated with ultrasound. Compared with the conventional method, ultrasound-assisted washing had reduced lipid oxidation as indicated by malondialdehyde content (from 2.50 ± 0.11 to 1.81 ± 0.11 mg/kg). The ultrasound treatment also improved water combining ability and increased the water hold capacity of the minced fish. The sarcoplasmic protein was removed, resulting in a concentration of myofibrillar protein that plays an important role in enhancing the surimi product's breaking force and gel strength. Therefore, low-intensity ultrasound-assisted washing effectively improved the gel properties of surimi from the yellowstripe scad.
