Red palm oil (RPO), besides providing calorie density to the diet, is also the richest natural source of β-carotene, a precursor of vitamin A and an antioxidant that destroys singlet oxygen and free radicals. Chemical analysis of the fatty acid composition of RPO indicates that it has 50% saturated, 40% mono-unsaturated, and 10% polyunsaturated fatty acids. RPO contains 550 mg/g of total carotenoids, of which 375 mg/g represent β-carotene. It also contains 1,000 mg/g of tocopherols and tocotrienols. Nutritional values in rats fed 10% RPO in a 10% casein diet were comparable to those fed 10% ground nut oil (GNO) or 10% RBDPO (refined, bleached, deodorized palm oil). Rats fed RPO or RBDPO had significantly lower plasma cholesterol concentrations than those fed GNO. Significant inhibition of micro-somal 3-hydroxy-3-methylglutaryl coenzyme A reductase activity was observed in the RPO and RBDPO groups, indicating reduced synthesis of endogenous cholesterol. Toxicological studies also indicate that RPO is safe for human consumption. Indian school children fed supplementary snacks prepared with RPO for 60 days had significant increases in serum retinol levels as well as an increased liver retinol store, suggesting the ready bioavailability of β-carotene.

Extruded potato (P) and sweet potato (SP) products with red palm oil (RPO) were prepared under different conditions. Superior product characteristics such as sensory score, expansion ratio, and water solubility index, among others, were obtained at high extrusion temperature (150-155 °C) and low water feed rate to the extruder (50.4-50.8 mL/min). The optimal products, P1 and SP1, had high micronutrients as their total contents of β-carotene, squalene, tocopherols, and tocotrienols were 883.2, 304.4, 262.4, and 397.0 mg/kg of oil, respectively. The average peroxide value was 4.3 meq O2/kg oil, p-anisidine value 3.3, and induction period (100 °C) 11.4 h. Moreover, RPO extruded with P showed a better extrusion behavior but lower micronutrient retention and oxidative stability than that extruded with SP. Thus, the finding herein is important for investigating extrusion conditions, increasing variety, improving nutritional quality, assessing applicability and predicting the shelf-life of RPO-P/SP-extruded food.

Background: Deodorization of the olein fraction of red palm oil (OFRP) determines not only the taste of a multivitamin emulsion but also its antioxidant capacity. The emulsion product was formulated from OFRP, pumpkin juice (PJ), and dragon fruit juice (DFJ). This study aimed to optimize vacuum evaporation and nitrogen-assisted deodorizations of OFRP, observing levels of β-carotene, α-tocopherol, inhibition percentage of ABTS reduction, and ferric reducing antioxidant power (FRAP) activity. Methods: The deodorizations observed were vacuum evaporation in four conditions: (1) 90°C, 80±5 mmHg, (2) 100°C, 80±5 mmHg, (3) 90°C, 100±5 mmHg, (4) 100°C, 100±5 mmHg, and nitrogen-assisted in two flow durations: (1) 15 min and (2) 30 min. β-carotene, α-tocopherol, and butylated hydroxytoluene (BHT) were employed as standards. Results: The deodorized OFRP had fewer than 2% free fatty acids (FFA), lower than 3% peroxide value (PV), and lower than 4% acidic value (AV). Fluctuations of the β-carotene and α-tocopherol concentrations were observed in the deodorized OFRP. The final emulsion product had β-carotene of 259.9±1.4 to 271.7±2.4 ppm and α-tocopherol of 36.36±0.20 to 39.12±0.20 ppm. The total betacyanin of the emulsions were ±25% than DFJ. The emulsions had 22.93 to 32.11% of ABTS reduction inhibitory activity of the BHT activity and FRAP activity of 16.54±0.19 to 17.69±0.67 mM FeSO4•7H2O. Conclusions: The best vacuum evaporation optimized at 90 °C, 100±5 mmHg, 60 RPM for 1 hour. The best nitrogen-assisted deodorization was at 85±3°C and 1 l/minute of nitrogen for 15 minutes. The deodorization process affected the antioxidant activity of OFRP and emulsions.

This study aimed to evaluate the effect of maltodextrin combination with different encapsulation materials in the encapsulation of red palm oil by spray drying, in order to maximize encapsulation efficiency and retention of β-carotene. Maltodextrin was combined with xanthan gum (XG), gum arabic (GA), sodium caseinate (SC). The study was designed using a block randomized design with ten treatments and three replicates. The use of different combinations of encapsulation materials in this study had a significant effect (p&lt;0.05) on the characteristic of encapsulates. The best encapsulation efficiency and β-carotene retention were obtained with MD:XG at a combination of 99.7:0.3%, while the lowest encapsulation efficiency and β-carotene retention were obtained for MD:SC. Combination of MD:XG produced encapsulate with 1.03% of surface oil, 92.40% of oil retention, 72.05% of encapsulation efficiency, and 72.65% of β-caroten retention. The mixtures of different encapsulation materials influenced encapsulate morphology. The MD:SC encapsulate had higher dents and folds on encapsulate surface, whereas the combination of MD:XG resulted in a smoother surface of the encapsulate.
