Effects of electric pulse processing in increasing the efficiency of cotton oil from technical seeds

This article provides an analysis of the global demand for cottonseed oil consumption, the growing trend of cottonseed oil production and methods of obtaining vegetable oil based on modern technologies. Based on the results of the analysis, the electro technology of electric pulse processing of seed pulp was proposed to increase the efficiency of obtaining cottonseed oil from technical seeds. Experiments have shown that the maximum degree of damage to the seed nucleus by electric pulse treatment depends on the amount of oil extraction. It is also possible to reduce the roasting temperature of electrically pulsed seed pulp to 70-75 °C, and these parameters are considered be energy-saving parameters. It is possible to increase the amount of oil extracted from the seed and reduce energy costs in the technology through electro-pulse processing.

Climate Change: Impacts on the Production of Cotton in Pakistan

Climatic changes seriously threaten Agriculture globally year to year, especially in developing countries like Pakistan. Agricultural productivity directly influenced by Climatic factor i.e., increase in high temperature, heavy rainwater, precipitation, flood and deficiency of irrigation etc. Climate patterns reduce global temperatures by 2.9 to 5.5 degrees Celsius by 2060, and crop yields are at high risk of these trends. Extreme temperatures negatively regulate crop phenology, leading to significant reductions in crop yields. Temperatures and changes in the rainy season affect the cotton growth and make threats the stability of cotton production and quality in Pakistan. Cultivation of Cotton is especially targeted on its thread, but its oil extensively uses as an incoming vegetable oil and make an essential contribution to the oil industry across the country. Pakistani farmers survey and prepare to get quality fiber and lint yield, Pakistan also meets 18.8 percent demands of oil from cotton seeds. Additionally, there is strong need from industry to strengthen cotton oil so it can be used directly as vegetable cooking oil. This research provides approaching into the climatic conditions of Pakistan and their effect on the production of better cotton.

Cotton Oil Shortenings And Optimal Parameters Of Their Temperature Process

The tempering properties of shortening of fats based on cottonseed oil and products of its processing were studied. It has been experimentally established that the tempering of hard shortening has several advantages. The tempering temperature is carefully selected to obtain the desired crystal matrix in shortening. In the absence of this step, the crystal structure in the product continues to change with time and temperature during storage and transportation. The consistency of the shortening changes at influence of high or low temperatures even with proper tempering. However, there is always some recovery of consistency when the product returns to its primary storage temperature. Properly tempered shortening shows plasticity over a wider temperature range, as well as storage temperature fluctuations.
