“…There are two types of safflower oil which are regarded as beneficial in preventive medicine. One type is rather rich in monounsaturated oleic acid, the other in linoleic acid [Krist et al, 2008]. The high concentration of unsaturated fatty acids, especially linoleic acid, is considered to be valuable for the reduction of cholesterol levels [Czernichow et al, 2010;Higa et al, 2010;Suzuki et al, 2010].…”

Aim: The prevalence of dental erosion is still increasing. A possible preventive approach might be rinsing with edible oils to improve the protective properties of the pellicle layer. This was tested in the present in situ study using safflower oil. Methods: Pellicle formation was carried out in situ on bovine enamel slabs fixed buccally to individual upper jaw splints (6 subjects). After 1 min of pellicle formation subjects rinsed with safflower oil for 10 min, subsequently the samples were exposed in the oral cavity for another 19 min. Enamel slabs without oral exposure and slabs exposed to the oral cavity for 30 min without any rinse served as controls. After pellicle formation in situ, slabs were incubated in HCl (pH 2; 2.3; 3) for 120 s, and kinetics of calcium and phosphate release were measured photometrically (arsenazo III, malachite green). Furthermore, the ultrastructure of the pellicles was evaluated by transmission electron microscopy (TEM). Results: Pellicle alone reduced erosive calcium and phosphate release significantly at all pH values. Pellicle modification by safflower oil resulted in an enhanced calcium loss at all pH values and caused an enhanced phosphate loss at pH 2.3. TEM indicated scattered accumulation of lipid micelles and irregular vesicle-like structures attached to the oil-treated pellicle layer. Acid etching affected the ultrastructure of the pellicle irrespective of oil rinsing. Conclusion: The protective properties of the pellicle layer against extensive erosive attacks are limited and mainly determined by pH. The protective effects are modified and reduced by rinses with safflower oil.

“…On plantations, oil palms are 10 to 12 m in length, with large leaves, dense crowns, and a trunk between 45 to 55 cm in thickness at the bottom and between 40 to 45 cm at the top 11,19,26 . It is a tropical plant and prefers a moist, nutrient‐rich soil (pH 5.5–7.0), a moderately sunny location with yearly rainfall over 1000 mm, and dry periods that do not last longer than 3 months.…”

In recent decades, the demand for palm oil has constantly increased and with it the cultivation of oil palms. After a period of 25 years, the oil yield of the palm trees decreases and they are felled. The trees are cut into pieces and remain on the plantations. However, due to their high moisture and sugar content, fungi and molds cause problems for replanting. The use of the wood for the timber industry is difficult due to its structural characteristics. Biotechnological processes use microorganisms to produce relevant industrial products. The basis for each process is a culture medium that contains all necessary nutrients, especially carbohydrates. The culture medium makes up a high percentage of the costs, so alternative, cheaper substrates are preferred. In this review, we show and compare different analyses of the sap mechanically pressed from the oil palm trunk regarding its sugar and nutrient content. The total sugar concentration in the palm sap varies between 16.97–140 g L−1 and it is mainly composed of glucose, fructose, and sucrose. The comparison with common nutrient media and the results of fermentation processes already carried out on a laboratory scale show that palm sap offers great potential as a fermentation medium for biotechnological conversion into industrially relevant products. © 2021 The Authors Biofuels, Bioproducts and Biorefining published by Society of Chemical Industry and John Wiley & Sons, Ltd
