This study investigates the treatment of coconut oil using thermosonic treatment in combination with green coffee beans. Under a defined ratio of coconut oil to green coffee beans, the effect of different thermosonic time on the quality parameters, active substance content, antioxidant capacity, and thermal oxidative stability of coconut oil were investigated as a strategy to potentially improve the quality of oil. Results showed that the β-sitosterol content of CCO (coconut coffee oil) treated with the thermal method combined with green coffee bean treatment reached up to 393.80 ± 11.13 mg/kg without affecting the lipid structure. In addition, DPPH clearance equivalents increased from 5.31 ± 1.30 mg EGCG/g to 71.34 ± 0.98 mg EGCG/g, and the ABTS clearance equivalent was 45.38 ± 0.87 mg EGCG/g versus 0 for the untreated sample. The improvement in thermal oxidation stability of treated coconut oil is also significant. The TG (Thermogravimetry) onset temperature was elevated from 277.97 °C to 335.08 °C and the induction time was elevated up to 24.73 ± 0.41 h from 5.17 ± 0.21 h. Thermosonic treatment in combination with green coffee beans is an ideal option to improve the quality of coconut oil. The results of this article provide new ideas for the development of plant-blended oil products and the new utilization of coconut oil and coffee beans.

Non-communicable diseases (NCD) are associated with inflammation and oxidative stress which is further associated with omega-6 (ω6) and omega-3 (ω3) fatty acid (FA) imbalance favoring ω6 FA. By improving ω3 FA consumption, this imbalance can be altered to control NCD. Previously we have reported blends of flaxseed oil (FSO, ω3 FA) with palm olein (PO) or coconut oil (CO) were thermo-oxidatively stable with good storage stability and could improve ω6:ω3 ratio in cell lines.

This research aimed to evaluate the use of edible coating from a combination of liquid smoke and turmeric extract as a preservative for mackerel at room temperature. Liquid smoke was obtained from the pyrolysis of oil palm empty fruit bunches (OPEFB) at a temperature of 380 °C and purified by distillation at 190 °C. Liquid smoke with a concentration of 3% was combined with turmeric extract at a ratio of 2, 4, 6, and 8 g/L (CLS 2:1, CLS 4:1, CLS 6:1 and CLS 8:1).

This study aims to verify the effects of prolonged ingestion of coconut oil on the adrenal glands of Mongolian gerbils. Mongolian gerbils were used as an experimental model due to the morphological similarity of the adrenal glands to those of primates. Male Mongolian gerbils, 3 months of age, were divided into three experimental groups (n=12): an intact control group, which received no treatment, a gavage control group, which received 0.

Objective: To determine the effects of sunflower seed oil and coconut oil on the skin integrity and weight gain of preterm infants in the neonatal ICU.
Methods: In this randomized controlled trial, 66 preterm neonates (34-37 weeks' gestation) in the neonatal ICU of a training and research hospital were equally divided into three groups: sunflower seed oil, coconut oil, and control. The weights of neonates in all three groups were measured at admission to the neonatal ICU, at discharge, and at 1 month postdischarge.
