Physical and chemical characterization of oil extracted from Citrofortunella microcarpa, Hibiscus sabdariffa and Artocarpus heterophyllus seeds

Abstract

Consumable plant oils had been related with highly nutritional content and antioxidant source that provide crucial health benefits. Hence, in this study a series of experimental work and analysis were conducted to evaluate the practicability and the properties of oil extraction from seeds of calamansi (Citrofortunella microcarpa), roselle (Hibiscus sabdariffa), and jackfruit (Artocarpus heterophyllus). The yield, antioxidant activities, iodine value, saponification value, and peroxide value of extracted seed oils were studied. Results obtained shown that among the three seeds species, calamansi seeds resulted in the highest yield of 32.7%, followed by roselle seeds with a yield of 11.00% and lastly, jackfruit seeds with the highest yield obtained was only 0.60%. Antioxidant activities conducted has shown that roselle with EC50 of 49.04 mg/mL has greater antioxidant properties as compared with calamansi with EC50 of 109.74 mg/mL. Iodine value determined for unheated oil has resulted in a value of 100.83 g I2/100g oil and 110.60 g I2/100g oil that has classified roselle and calamansi seeds oil under the non-drying oil categories and heating effect shown a slight decrease in the iodine value due to loss of unsaturation within the oil. Both calamansi and roselle seed oils did not show significance reduction in saponification value upon heating. Peroxide value for roselle and calamansi seeds oil under unheated condition was determined to be 10.36 meq/kg and 24.86 meq/kg respectively.

Phytochemical Properties, Antioxidant Activity and α- Amilase Inhibitory of Curcuma Caesia

“…This study is similar to Mukunthan's research (2017) Curcuma caesia samples from India which were extracted using polar solvents resulted in lower antioxidant activity in polar solvents, and yields in polar solvents were smaller than non-polar solvents [14]. Research [41] in hexane solvent Calmination yielded a yield that is higher than petroleum ether solvent and produces a quite strong antioxidant activity. in this study the yield was 1.6% and relatively small.…”

Potential of Bioresource Usage in The Tropical Area of Southeast Asia for Human Mental Well-Being

“…Plant flower from tropical area that consist of anthocyanin such as Hibiscus rosa-sinensis L. Clitoria ternatea L. and Hibiscus sabdariffa L. are good alternative food coloring compared with widely used cochineal which is from insect Dactylopius coccus [6]. Seed of Citrofortunella microcarpa, Hibiscus sabdariffa and Artocarpus heterophyllus widely used in Tropical Area for the oil extraction for the high nutritional value and antioxidant properties [7].…”

Structural Elucidation of the Masp1 and Masp2 Protein from Nephila Pilipes Web Via Bioinformatics Approaches

“…In brief, the manufacturing of silk proteins was formed inside the major ampullate gland of a spider whereby the major ampullate spidroin (MaSp) one and two were used in constructing the web frames, lifeline, and used to capture prey as studied by Hajer and Řeháková [3]. The specific characteristics of spidroins have become the most common research to unravel the molecular structure of spidroin, which contains a great variety of mechanical, physicochemical, and biological properties as reviewed by Fai et al, [4].…”
