“…Oleaginous microalgae with fast growth, high oil content, but the production cost is higher, and in the downstream processing, the costs of breaking the cell wall and extracting oil have increased than traditional plant source fuel. And we need improve the microalgae oil production technology from microalgae cultivation, cell broken, oil extraction, and oil processing (Enamala et al, 2018;Baskar et al, 2019;Karmakar and Halder, 2019;Li P. et al, 2019;Nagappan et al, 2019). The feasibility of expanding production beyond the laboratory scale needs to be studied.…”

Microalgae are a valuable and rich source of oil. By the means of using microalgae oil as raw materials or additives for edible oil will improve the nutritional and edible value of the latter. This paper compares the lipid content and fatty acid composition of microalgae and traditional oil crops, elaborates the lipid synthesis mechanism of microalgae cells and the strategies of promoting lipid accumulation both from environmental pressure and from molecular pressure, summarizes the methods of breaking microalgae cell walls and extracting oil, analyzes the nutritional value, toxicity, antioxidant, and economic feasibility issues to be considered in microalgae edible oil. It is hoped that this study could provide theoretical basis for the actual production of microalgae edible oil, and provide inspiration for the research on the synthesis, accumulation, extraction and preparation of microalgae oils.

“…This is possible through a variety of chemical, biochemical, and mechanical techniques in order to maximize yields while minimizing alterations on the quality of the product [11]. It is the most important part of oil processing and depends on the part that contains the oil, which is the kernel, the seed, or the pulp [12]. The separation of bio-active compounds of interest in different industries such as food and pharmaceutical usually employs the use of large amounts of solvents (water, n-hexane, ethanol, chloroform, methanol, petroleum ether, etc.).…”

“…The separation of bio-active compounds of interest in different industries such as food and pharmaceutical usually employs the use of large amounts of solvents (water, n-hexane, ethanol, chloroform, methanol, petroleum ether, etc.). Over the last decades researchers have concentrated lots of efforts on the design of efficient and more sustainable methods of extraction which are less detrimental to the environment [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Extractions have moved from the conventional solvent and mechanical extractions to improved nonconventional techniques such as Supercritical Fluid Extraction (SFE) and extraction assisted by ultrasound (UAE) and microwaves(MAE) [16][17][18].Grinding is a very essential operation in the preparation of materials for oil extraction irrespective of the method that follows because when carefully controlled it can lead to the achievement of high oil yields and positively influences downstream operations [19].…”

Optimization Methods for the Extraction of Vegetable Oils: A Review

2020

View full text Add to dashboard Cite

Most seed oils are edible while some are used generally as raw material for soap production, chocolate, margarine, and recently in biodiesel formulations as potential candidates capable of replacing fossil fuels which are costly and destructive to the environment. Oilseeds are a green and major reservoir which when properly exploited can be used sustainably for the production of chemicals at both the laboratory and industrial scales. Oil extraction is one of the most critical steps in seed oil processing because it determines the quality and quantity of oil extracted. Optimization of the extraction conditions for each extraction method enhances yield and quality meanwhile a carefully chosen optimization process equally has the potential of saving time and heat requirements with an associated consequence on cost reduction of the entire process. In this review, the techniques used to optimize oil extraction from plant materials which can be consulted by stakeholders in the field are brought to focus and the merits and demerits of these methods highlighted. Additionally, different types of optimization techniques used for various processes including modeling and the software employed in the optimization processes are discussed. Finally, the quality of the oil as affected by the methods of extraction and the optimization process used are also presented.

Chemical-Free Recovery of Crude Protein from Livestock Manure Digestate Solid by Thermal Hydrolysis

Protein is becoming an increasingly important resource for a variety of commercial applications. Yet, a large volume of protein is being wasted. Notably, livestock manure solids have a significant content of protein which is not only underutilized, but prone to runoff and eventual breakdown to reactive nitrogen compounds, contributing to eutrophication. It would be desirable to remove protein before it causes environmental hazards and then convert it to value-added commercial applications. We have developed a novel thermal hydrolysis process (THP) to extract crude protein from livestock manure solid, or manure digestate solid (MDS) in particular, without the use of any chemical. We demonstrate the versatility of our new process to control the molecular weight (MW) distribution of the extracted protein hydrolysate (PH). The antioxidant activity of the crude protein hydrolysate (CPH) has been examined through Oxygen Radical Absorbance Capacity Assay. The results have shown that our CPH had its antioxidant capacity against the peroxyl radical similar to that of vitamin E and exhibited almost 7 times as strong inhibition against the hydroxyl radical as vitamin E. We also evaluated the nutritional value of our PH by analyzing its amino acid composition and the MW distribution through amino acid analysis, SDS-PAGE, and MALDI-TOF mass spectroscopy. The characterizations have revealed that the PH recovered from MDS had 2.5 times as much essential amino acids as soybean meal on dry matter basis, with the MW distribution ranging from over a hundred Da to 100 KDa. Finally, the protein powder was prepared from the extracted CPH solution and its composition was analyzed.
