Impacts of Precipitating Methods on the Physicochemical, Rheological, and Functional Properties of Borassus aethiopum Mart Fruit Pulp Pectin| Chapter 3 | Emerging Challenges in Agriculture and Food Science Vol. 5

Borassus aethiopum Mart tree fruits are underused in Africa, with the majority of them allowed to decay in the field. These fruits contain a lot of pectin, making them good raw materials for the pectin business. Because the extraction processes alter the properties of B. aethiopum fruit pectin, it was vital to emphasise the effects of the precipitating methods on the quality of the isolated pectin. Different precipitating solvents were tested in this investigation, and the end products' properties were identified. The functional and rheological characteristics of pectin precipitated with isopropanol (IPA), acetone (ACTN), and the 50/50 IPA-ACTN solvents varied greatly. Precipitated isopropanol (IPA) pectin had the highest emulsifying activity (p0.05) and the best gel sensory property. High purity pectin with high viscosifying, emulsifying, and gelling capabilities was produced regardless of the precipitating solvent. Because extraction and precipitation techniques separate pectin samples with varying functions, commercial production of pectin from B. aethiopum fruit pulp should be regulated by its intended application.

Study on Performance and Emission Studies on Cashewnut Shell Liquid Bio-Oil Fuelled Diesel Engine with Acetone as Additive | Chapter 6 | New Ideas Concerning Science and Technology Vol. 10

 Vegetable oils may be used as a partial or complete replacement for diesel fuel. We used Acetone as an additive in this study to look into the possibility of using higher percentages of bio-oil in diesel engines without any retrofitting. Pyrolysis was used to create bio-oil. The feed stroke for bio oil was cashew nut shell liquid (CNSL). B20 diesel fuel is a type of number 2 diesel fuel that contains 20% bio oil and 80% diesel fuel. In a single cylinder, four stroke direct injection diesel engine, the effects of Acetone, blended with B20 in 4, 8, 12 percent by volume, were tested. Performance tests were used to evaluate the effect of test fuels on engine torque, speed, brake specific fuel consumption, brake thermal efficiency, and exhaust gas temperature. Emission experiments were used to assess the impact of blends on CO, HC, NO, and smoke opacity. As compared to neat diesel service, HC emission was reduced by 34%, smoke density was reduced by 16%, and NO emission was reduced by 49.4 percent when the engine was powered by 12 percent Acetone with B20. CNSL can also be used as a diesel engine's fuel. As a result, a combination of 20% CNSL bio oil and 12% acetone as an additive was found to be the best alternative fuel blend for diesel engines that did not require any engine modifications.
