Cocoa butter naturally occurs in cocoa bean. It is present about 50% of cocoa nib. It is highly resistant to oxidation due to presence of high level of natural tocopherol. It is brittle at room temperature and its melting point is between 34o C to 38o C. But, cocoa butter is expensive and its price is subjected to large fluctuations. That’s why some alternatives for cocoa butters are produced, such as cocoa – butter equivalents (CBEs , like from enzymatic inter-esterification of tea seed oil and fatty acid methyl esters), cocoa-butter substitute (CBSs, esterifies propoxylatedglycerin containing acyl groups derived from saturated linear fatty acids, at least 50 moles percent of the total acyl groups are used ) and cocoa-butter replacers (CBRs, like evaluation of milk fat fractional and modified techniques for making CBR.) Their composition according to triglycerides, fatty acids, sterols and other unsaponifiable components are discussed in this paper. Coconut oil, non-lauric contained fats like palm oil, soybean oil, rapeseed oil, can be used as replacer. These alternatives have various advantages; it improves fat stability, reduces fat migration, and incorporates softness to the product. As the alternatives do not require tempering, it is easier to achieve glassy texture. This work reviews on the theory of the compositional data of vegetable oils, and fats which are used as cocoa – butter alternatives in the production of chocolate.

The article analyzes the role of essential polyunsaturated fatty acids (PUFA), especially omega-3 series in humans and animals. The biosynthesis of essential PUFA in humans and animals is very limited, so they must be consumed with food (feed). Тhe ratio of omega-3 and omega-6 PUFA is very important. Biomembranes of animal cells contain about 30% PUFA with a ratio of ω-6/ ω-3 1-2. As this ratio increases, the physicochemical properties of biomembranes and the functional activity of their receptors change. The regulatory function of essential PUFA is that in the body under the action of oxygenase enzymes (cyclooxygenase, lipoxygenase) are formed extremely active hormone-like substances (eicosanoids and docosanoids), which affect a number of physiological processes: inflammation, immunity, metabolism. Moreover, ω-6 PUFA form eicosanoids, which have pro-inflammatory, immunosuppressive properties, and ω-3 PUFAs form eicosanoids and docosanoids, which have anti-inflammatory and immunostimulatory properties. Deficiency of essential PUFA, and especially ω-3 PUFA, leads to impaired development of the body and its state of health, which are manifestations of avitaminosis F. Prevention and treatment of avitaminosis F is carried out with drugs that contain PUFA. To create new, more effective vitamin F preparations, it is necessary to reproduce the model of vitamin F deficiency. An experimental model of vitamin F deficiency in white rats kept on a fat –free diet with the addition of coconut oil, which is almost completely free of unsaturated fatty acids, and saturated fatty acids make up almost 99 % of all fatty acids was developed. The total content of ω-6 PUFA (sum of linoleic and arachidonic acids), the content of ω-3 PUFA (α-linolenic, eicosapentaenoic and docosahexaenoic acids) in neutral lipids (triglycerides and cholesterol esters) defined. Тhe content of ω-6 PUFA under the influence of coconut oil decreased by 3.3 times, and the content of ω-3 PUFA - by 7.5 times. Тhe influence of coconut oil, the content of ω-6 PUFA decreased by 2.1 times, and the content of ω-3 PUFA - by 2.8 times. The most strongly reduces the content of ω-3 PUFA, namely eicosapentaenoic, coconut oil, starting from 5 %. Consumption of FFD with a content of 15 % coconut oil reduces the content of eicosapentaenoic acid to zero, ie we have an absolute deficiency of one of the most important essential PUFAs, which determined the presence of vitamin F deficiency.

Background: Coconut oil is an edible oil obtained from fresh, mature coconut kernels. Few studies have reported the anticancer role of coconut oil. The fatty acid component of coconut oil directly targets the liver by portal circulation and as chylomicron via lymph. However, the anti-cancer activity of coconut oil against liver cancer cells and oral cancer cells is yet to be tested. The active component of coconut oil, that is responsible for the anticancer activity is not well understood. In this study, three different coconut oils, Virgin Coconut Oil (VCO), Processed Coconut Oil (PCO) and Fractionated Coconut Oil (FCO), were used. Objective: Based on previous studies, it can be hypothesized that fatty acids in coconut oil may have anticancer potential and may trigger cell death in cancer cell lines. Methods: Each cell line was treated with different concentrations of Virgin Coconut Oil (VCO), Processed Coconut Oil (PCO) and Fractionated Coconut Oil (FCO). The treated cells were assayed by MTT after 72 hr of incubation. The fatty acid composition of different coconut oils was analyzed by gas chromatography. Result: Different concentrations of coconut oils were used to treat the cells. Interestingly, the anticancer efficacy of VCO, PCO and FCO was not uniform, rather the efficacy varied from cell line to cell line. Only 20% VCO showed significant anticancer activity in HepG2 cells in comparison to 80% PCO against the KB cell line. Remarkably, 20% of PCO and 5% of FCO showed potential growth inhibition in the KB cell line as compared to 80% PCO in HepG2 cells. Moreover, there was a difference in the efficacy of VCO, PCO and FCO, which might be due to their fatty acid composition. Comparing the anticancer efficacy of VCO, PCO and FCO in this study helped to predict which class of fatty acids and which fatty acid might be associated with the anticancer activity of VCO. Conclusion: This study shows that VCO, PCO and FCO have anticancer efficacy and may be used for the treatment of cancer, especially liver and oral cancer.

Abstract Objectives Non-alcoholic fatty liver disease (NAFLD) represents the major cause of pediatric chronic liver pathology in the United States. The objective of this study was to compare the relative effect of inclusion of isocaloric amounts of saturated medium-chain fatty acids (hydrogenated coconut oil), saturated long-chain fatty acids (lard) and unsaturated long-chain fatty acids (olive oil) on endpoints of NAFLD and insulin resistance. Methods Thirty-eight 15-d-old Iberian pigs were fed 1 of 4 diets containing (g/kg body weight × d) 1) control (CON; n = 8): 0 g fructose, 10.5 g fat, and 187 kcal metabolizable energy (ME), 2) lard (LAR; n = 10): 21.6 g fructose, 17.1 g fat (100% lard) and 299 kcal ME, 3) hydrogenated coconut oil (COCO; n = 10): 21.6 g fructose, 16.9 g fat (42.5% lard and 57.5% coconut oil) and 299 kcal ME, and 4) olive oil (OLV, n = 10): 21.6 g fructose, 17.1 g fat (43.5% lard and 56.5% olive oil) and 299 kcal ME, for 9 consecutive weeks. Body weight was recorded every 3 d. Serum markers of liver injury and dyslipidemia were measured on d 60 at 2 h post feeding, with all other serum measures assessed on d 70. Liver tissue was collected on d 70 for histology, triacylglyceride (TG) quantification, and metabolomics analysis. Results Tissue histology indicated the presence of steatosis in LAR, COCO and OLV compared with CON (P ≤ 0.001), with a further increase in in non-alcoholic steatohepatitis (NASH) in OLV and COCO compared with LAR (P ≤ 0.01). Alanine and aspartate aminotransferases were higher in COCO and OLV (P ≤ 0.01) than CON. All treatment groups had lower liver concentrations of methyl donor's choline and betaine versus CON, while bile acids were differentially changed (P ≤ 0.05). COCO had higher levels of TGs with less carbons (Total carbons < 52) than all other groups (P ≤ 0.05). Several long-chain acylcarnitines involved in fat oxidation were higher in OLV versus all other groups (P ≤ 0.05). Conclusions Inclusion of fats enriched in medium-chain saturated and long-chain unsaturated fatty acids in a high-fructose high-fat diet increased liver injury, compared with fats with a long-chain saturated fatty acid profile. Further research is required to investigate the mechanisms causing this difference in physiological response to these dietary fat sources. Funding Sources ARI, AcornSeekers.
