In this study, the physicochemical properties, composition, thermal properties, and crystal microstructure of fractionated bambangan kernel fat stearin and palm oil mid-fraction blends were investigated with respect to a potential cocoa butter equivalent. The blends were prepared in five ratios, and all of the blends exhibited similar physicochemical properties to cocoa butter. Although all of the blends had similar physicochemical properties, the blend containing 70% bambangan kernel fat stearin and 30% palm oil mid-fraction showed remarkable similarity to cocoa butter. The blend had similar fatty acid and triacylglycerol content to cocoa butter with 18.74% palmitic acids, 38.26% stearic acids, 34.05% oleic acids, 15.20% 1,3-dipalmitoyl-2-oleoyl glycerol, and 29.74% 1,3-disteroyl-2-oleoyl glycerol with improved thermostability (high solid fat content at 30 °C but reaching 0% at 40 °C). It also exhibited spherulite crystals with a needle-like crystal structure of 50 µm. This mixture showed good compatibility with cocoa butter at all mixing ratios; hence, it is suggested as a potential cocoa butter equivalent. Full article

Currently, research on the bambangan-fruit seed has become interesting because of its potential application as a cocoa butter alternative. This work aimed to determine the changes in the quality of the extracted bambangan-seed fat (BSF) obtained using hexane, petroleum ether, and ethanol. The extraction solvents affected the total fat content (TFC), physicochemical properties, fatty-acid profile, triacylglycerol composition, and crystalline structure of the extracted BSF. The results showed that BSF has a high content of 1,3-distreoyl-2-oleoyl-glycerol (SOS). The solvent-type significantly (p < 0.05) impacts the stearic and oleic acids of the extracts, resulting in apparent changes in the high-melting symmetrical triacylglycerols, such as SOS. Petroleum-ether-extracted BSF has a high stearic acid of 33.40%, followed by that of hexane- and ethanol-extracted BSF at 29.29% and 27.84%, respectively. Moreover, the spherulitic microstructure with needle-like crystals of the extracts also ranges from 30 to 70 µm in diameter. Hexane-extracted BSF illustrated a less-dense, spherulitic, crystalline microstructure with a less-granular centre than those extracted using the other solvents. The results suggested that the quality of the extracted BSF obtained from the nonpolar solvents of hexane and petroleum ether are better than that extracted using ethanol. Full article

Abstract
This study provides new data on the various carotenoids found in bambangan (Mangifera pajang Kosterm.) peel and pulp extracts, such as all-trans-α- and β-carotene, cis-β-carotene, 9-cis-β-carotene, and cryptoxanthin. Chemical and biological antioxidant assays were determined to evaluate [...] Read more.
This study provides new data on the various carotenoids found in bambangan (Mangifera pajang Kosterm.) peel and pulp extracts, such as all-trans-α- and β-carotene, cis-β-carotene, 9-cis-β-carotene, and cryptoxanthin. Chemical and biological antioxidant assays were determined to evaluate the antioxidant capacity of bambangan peel and pulp extracts. Bambangan pulp had higher α- and β-carotene contents (7.96 ± 1.53 and 20.04 ± 1.01 mg/100 g) than its peel (4.2 ± 0.14 and 13.09 ± 0.28 mg/100 g); the cryptoxanthin contents of bambangan peel and pulp were 0.60 and 1.18 mg/100 g, respectively. The antioxidant activity results determined by chemical assay using the 2,2-diphenyl-2-picrylhydrazyl (DPPH) method showed that bambangan peel extract had higher DPPH radical scavenging activity than its pulp. In the biological assays bambangan peel and pulp had protective effects against hemoglobin and LDL oxidation at an extract concentration of 1 ppm. Bambangan peel is a therefore a potential source of natural antioxidants and could be utilized as a functional ingredient. Full article
