“…At the same time, the reaction releases TAGs trapped by the PLs. The overall extra yield provided by the generated DAGs and the released TAGs is around 2% (Dijkstra, 2010;Elena et al, 2017;Sein et al, 2019). For soybean oil, microbial PLCs with dual speci city for PC and PE are the most effective enzymes, since together these PLs usually account for more than 70% of the total PLs present in soybean oil.…”

The increasing demand pressures the vegetable oil industry to develop novel refining methods. Degumming with type C phospholipases (PLCs) is a green technology and provides extra oil. However, natural PLCs are not active under the harsh conditions used in oil refining plants, requiring additional unit operations. These upfront capital expenditures and the associated operational costs hinder the adoption of this method. Here, we present a process based on ChPLC, a synthetic PLC obtained by consensus sequence design, possessing superior thermal stability and catalytic properties. Using ChPLC, crude soybean oil degumming was completed at 80 °C in 30 min, the temperature and residence time imposed by the design of existing oil refining plants. Remarkably, an extra yield of oil of 2% was obtained using 60% of the dose recommended for PLCs marketed today, saving upfront investments and reducing the operational cost of degumming. A techno-economic analysis indicates that, for medium size plants, ChPLC reduces the overall cost of soybean oil enzymatic degumming by 58%. The process presented here facilitates the implementation of enzymatic technologies to oil producers, regardless of their processing capacity, bringing potential annual benefits in the billion-dollar range for the global economy.

“…Phosphotic acid can change it to hydratable shape. Hydratable phospatides like phosphatidycholine (lesitin), can easily remove from oil using water [24], [16], [20]. Besides of degumming process, neutralization using NaOH and high temperature deodorization can damage the carotene [25], [26].…”

Red Palm Olein (RPOn) is the result of refining and fraction of Crude Palm Oil (CPO). In the conventional refining of CPO, carotene which is a pro-Vitamin A is intentionally removed to get a clear colored oil.. This research is comparing between two methods are Method I and Method II. Method I is started from degumming process (acid degumming), Neutralization, deodorization, and then fractionation. Meanwhile, Method II is started from degumming process (water degumming), fractionation and then deodorization. Optimization using RSM method with CCD program, carried out in the deodorization process of the selected by method II. Method II is producing RPOn with 0.1949% moisture content, 0.8743 mE/kg peroxide value, 0.148% FFA, 57.5380 ppm of beta carotene and 100.5526 ppm of tocopherol alpha. Improvement of the deodorization process using RSM by setting the temperature to 90 0 C, vacuum pressure to 50 cmHg and 2.98 hours of deodorization process will be produce RPOn with 0.03% FFA.
