Influence of Collection Areas on the Physico-chemical and Nutritional Characterization of Dried Mangoes Consumed in Chad for Better Post-Harvest Valorization | Chapter 4 | Current Perspectives in Agriculture and Food Science Vol. 9

  

Background: Mango plays a very important nutritional role, providing micronutrients required for the proper functioning of the human body and protection against major chronic diseases such as cardiovascular, neurodegenerative and metabolic diseases, as well as cancers.

 

Aim: This study aims to determine the chemical and nutritional characterization of dried mangoes consumed in Chad for better post-harvest valorization.

 

Methodology: The study was conducted in the Food Sciences and Nutrition Research Laboratory (LARSAN), Faculty of Human Health Sciences, University of N’Djamena BP1117, Chad; between February 2022 and April 2023. Dried mangoes were collected from five localities (Doba, Bebedjia, Koumra, Moundou, and Bongor), were labeled DbaA, Bja, Mdou, Kmr, and Bgr, and then stored in a refrigerated cooler for physico-chemical analyses using standard methods to determine the chemical composition of various samples. The statistical analysis was carried out using the ANOVA test (analysis of variance test) followed by the Fisher post hoc test to compare means.

 

Results: These analyses showed that the water content of dried mangoes was not significantly influenced (p = 0.0014) by the production area. No significant difference (P>0.05) was observed in the Vitamin composition of dried mangoes from the five locations. Protein, carbohydrate, lipid, and energy contents per 100 g ranged from 3.89 to 3.93 g, 94.91 to 104.72 g, 1.35 to 2.07 g, and 360.48 to 381.36 kcal/100 g, respectively. The reducing sugar content was high (77.73 g/100g) in Doba samples, compared to that from Moundou (76.51 g/100g). Starch and amylopectin contents were not significantly affected by production area (110.32 to 112.07 g/100g and 94.28 to 97.20 g/100 g, respectively). Calcium (Ca), sodium (Na), potassium (K), magnesium (Mg), and iron (Fe) were present in all samples with respective contents varying from 72.66 to 73.49 mg/100 g, 11.41 to 12.58 mg/100 g, 79.15 to 85.97, 68.78 to 70.59 mg/100 g, and 1.05 to 1.79 mg/100 g. Vitamin C and carotenoid contents varied, respectively, from 69.37 to 70.15 µg/100 g and from 249.25 to 274.15 µ g/100 g. Principal Component Analysis revealed that samples E1DOBA and E2BGA and E3Kmr and E4Mdr have the same physico-chemical characteristics.

 

Conclusion: These findings revealed that dried fruits from all localities were kept well, as their water content fell within the norm. Thus, these results demonstrate that respecting the drying and storage conditions for dried mango fruits, regardless of the zone, would enable the best possible preservation of nutritional properties while ensuring year-round availability.

Comprehensive Assessment of Soil Chemical and Physical Properties across India | Chapter7 | Chemical and Materials Sciences: Research Findings Vol. 1

Agriculture is considered as the backbone of Indian Society. A nutritious diet is essential for leading a quality lifestyle and it is derived from agricultural fields. We should prioritize and preserve the quality of our soil. This chapter will promote knowledge on the research of various aspects of soil and their attributes. This study was conducted to inform people that each crop, depending on its requirements, can easily be directed towards a soil that suits its physico-chemical needs. This study examines the chemical and physical properties of soils across various regions of India, focusing on their agricultural production and environmental sustainability. The study was carried out in the year 2023-2024. Chemical testing revealed notable variations in soil pH and nutrient content. Phosphorus ran from 15 to 47 ppm; potassium from 180 to 270 ppm; nitrogen from 12 to 22 ppm; and pH from 5.4 to 6.8. Revealing the intricate interactions among several components improves correlation analysis and offers important information for the development of concentrated soil management strategies. The soil structure determines water retention capacity and nutrient availability regardless of loam, sand, or clayey. Studies of heavy metals revealed varying degrees of mercury, cadmium, arsenic, and lead all around India. Since it shows the changes in easily available water over time, the moisture content of the soil is vital for irrigation planning and agriculture. Emphasising the need for soil porosity (28.45% to 40.17%) and permeability (7.83 to 11.23 cm/hr) for water movement and root penetration is absolutely vital. These findings support informed decision-making in soil management, promoting sustainable agricultural practices tailored to regional soil characteristics. In conclusion, the comprehensive assessment of soil properties across diverse regions of India provides crucial insights for sustainable land management and agricultural practices. Future research should focus on long-term monitoring of soil health indicators and the impact of climate change on soil properties.

Systematic Analysis of Energy Coal Mixtures in Judicial Practice. Case Study: Jiu Valley, Hunedoara County, Romania | Chapter 10 | Advanced Aspects of Engineering Research Vol. 10

 Technical knowledge and/or determining the nature of certain coal wastes, often from old stockpiles, in order to remove them are two circumstances in which it is important to explain the types of coal that come into the composition of mixtures. The proposed approach is focused on identifying and describing the mineralogical-petrographic and physico-chemical properties that can contribute to a diagnosis in coal type differentiation. In the first stage of systematic research, mineralogical analysis is used to identify the various types of coal found in the sample. Granules are extracted from the various types of coal present in the sample and the characteristics that define them are determined: moisture and hygroscopic moisture content, volatile matter content, fixed carbon content, agglutination characteristics, and so on. In addition, the mixtures' characteristics are calculated on another part of the sample, and their structure is determined using algebraic methods. There are times when an assessment of the amount of material in a stockpile or that can be stored in a dump is needed. This could be achieved by modelling the stockpile surface (upper surface) and the ground underneath the stockpile (lower surface) in CAD software, and then calculating the volume between the upper and lower surfaces, limited by the stockpile's boundary.
