Characterization and nutritional content of Terminalia catappa kernel and its oil from Sabah, Malaysia

This study was aimed to evaluate the nutritional quality of Terminalia catappa kernel oil (TCKO) and its characterization as well as total phenolic content cultivated in two different locations in Sabah, Malaysia. TCK contained 6.87 to 6.92% moisture, 4.54 to 4.77% ash, 21.98 to 22.44% protein, 5.13 to 5.36% total fibre, 6.88 to 7.01% carbohydrate, and 49.45 to 54.47% oil. The iodine value (IV), free fatty acid (FFA), peroxide value (PV), refractive index (RI), and total phenolic content (TPC) were found to be comparable to that of edible oils. The FFA, IV, PV, color, and TPC values showed significant differences. These results also revealed that the oil from Kota Kinabalu TCK contain more unsaturated fatty acids and display lower oxidative stability as compared to oil extracted from Keningau TCK. From the nutritional point of view, TCK oil had interesting fatty acid composition, displaying the lowest atherogenicity and thrombogenicity indices, highest polyunsaturated/saturated fatty acids and hypocholesterolemic/hypocholesterolemic ratios, respectively. This is suggested that TCK oil have potential to become a new source of healthy edible oil

Physicochemical properties of cocoa butter replacers from supercritical carbon dioxide extracted mango seed fat and palm oil mid-fraction blends

Supercritical carbon dioxide (scCO2 ) extracted mango seed fat (MSF) was blended with palm oil mid-fraction (POMF) to obtain cocoa butter replacers (CBRs). The fatty acid constituents and physicochemical properties of the formulated blends were analysed by gas chromatography (GC). In this study, the fatty acid constituents and other physicochemical properties such as iodine value (43.2 to 43.4 g I2 /100 g fat), saponification value (195.7 to 195.9 mg KOH/g fat), acid value (2.1 to 2.7%), and slip melting point (33.8 to 34.9°C) of blends MSF/POMF at ratios 85/15, 80/20, 75/25, and 70/30 were found similar to the physicochemical properties of commercial cocoa butter. Thus, it could be concluded that the MSF/POMF blends that are blends 85/15, 80/20, 75/25, and 70/30 (3 to 6) could be suggested as CBRs in terms of the physicochemical properties like fatty acid constituents, iodine, saponification and acid values and slip melting poin

Fatty acids, triacylglycerols, thermal properties, morphology and antioxidant activity of Canarium odontophyllum seed oil

Canarium odontophyllum Miq. (Dabai) is an underutilized fruit and its oil has the potential to broaden the availability of healthy edible oil. The objective of this study was to determine the physiochemical and thermal properties, fatty acid and triacylglycerol profiles, morphological behavior, and antioxidant capabilities of dabai seed oil (DSO) by using chromatographic and thermal techniques. The results showed that DSO has a low unsaturation values, high peroxide and refractive index values with a melting point at body temperature. DSO showed 56.47% saturated fatty acids, 40% unsaturated fatty acids and 29.88% of 1,3-dipalmitoyl-2-oleoyl-glycerol content. Some crystals showed larger than 30 μm in size and others smaller, including spherical, dot-covered spherulites between 0.5 and 5 μm in size. In addition, the amount of ferric reducing power and phenolic contents of DSO were 3.62±0.10 mMol of Fe2+/g and 21.73±0.98 mg GAE per 100 g of samples. The DSO mimics the composition of palm stearin and palm oil mid fraction and showed comparable physicochemical and thermal properties to that of commercial cocoa butter. The results showed that the DSO has a traceable amount of antioxidant activity and good potential to be developed as a healthy edible oil resource

Optimization of fat yield of Bambangan (Mangifera pajang) kernel using response surface methodology and its antioxidant activities

The objectives of this study are to optimize the extraction of fat from bambangan kernel using response surface methodology and to determine its antioxidant activities and total phenolic contents (TPC). Bambangan kernel was also investigated to determine proximate and amino acids in a pursuit to identify an innovative fruit which could be exploited in other food applications. Results for proximate compositions of bambangan kernel indicates moisture contents of 8.9%, crude protein contents of 4.1%, ash contents of 2.8%, and carbohydrate contents of 72.9% on dry weight basis. The highest fat yield of bambangan kernel was found to be 11.0% with optimum parameters at solvent volume of 329.7 ml (n-hexane), samples weight of 27.0 g, and extraction time of 7.6 h. 2,2-Diphenyl-1-picryl-hydrazyl (DPPH) free radical scavenging ability of bambangan kernel powder and fat were found to be 60.6 ± 2.1 and 35.2 ± 2.1 mg TEAC/100 g, respectively. Moreover, the ferric reducing antioxidant power (FRAP) of bambangan kernel powder and fat were 150.6 ± 2.4 and 119.0 ± 6.3 mM/100 g, respectively. The TPC of bambangan kernel powder was 118.6 ± 1.9 mg GAE/g, whereas kernel fat was 94.1 ± 2.1 mg GAE/g. The DPPH radical scavenging and FRAP activities showed a strong correlation with TPC in both bambangan kernel powder and fat. The high TPC of bambangan kernel and its fat indicated that the kernels should be further utilized or processed to other food, nutraceutical or pharmaceutical products instead of discarded as waste

A review on functional and nutritional properties of noni fruit seed (Morinda citrifolia L.) and its oil

Noni (Morinda citrifolia L.) is native to the Polynesian and recognized in the tropical and subtropical countries as a sustainable crop with feasible commercial applications. It has been reported that the interest in developing noni plant as a novel source of bioactive compounds are increasing by the day. This review describes the safety, nutritional values, and the properties of noni seed oil (NSO) with potential industrial uses. In particular, the bioactive compounds, anti-nutrients, antioxidant activity, and IC50 values of noni seed and the chemical composition of NSO are also described. NSO has high contents of polyunsaturated fatty acids, total phytosterols and tocopherols that could be better choices for patients with high cholesterol and cardiovascular diseases. Extracts of noni seed have been shown to possess bioactive compounds that exhibit antioxidant, anti-mutagenic, anti-tumor, anti-inflammatory, anti-allergic, anti-viral, anti-fungal, anti-microbial, and anti-carcinogenic properties. Bioactive compound-rich noni fruit seed could be a potential source of functional foods. Moreover, noni seeds could be a valuable new source of vegetable oil because of its nutritional properties and non-toxic nature along with the increasing supply of seeds as by-products from noni juice industry. Comprehensive studies are needed on NSO to explore more potential product development. Moreover, further study is needed on the development of nutraceutical food products from noni seed by-products

Application of supercritical CO2 in lipid extraction – A review

Supercritical fluid extraction (SFE) offers an alternative method to conventional extraction of fatty acids. SFE was developed for analytical application in the mid-1980s in response to the desire to reduce the use of organic solvents in the laboratory environment, and it is now becoming a standard method for the extraction, fractionation, refinement and deodorization of lipids or essential oils containing sample matrices at the industrial scale. This paper reviews applications of supercritical fluid technology in fatty acid/lipid extraction using carbon dioxide. Carbon dioxide is an ideal supercritical fluid because of its environmentally benign, non-toxic, non-flammable, non-polluting, recoverable characteristics and its ability to solubilise lipophilic substances. A summary of commercial applications and examples of recent developments of SFE in the food processing industry are also reviewed
