Proteomic Analysis of the Major Alkali-Soluble Inca Peanut (Plukenetia volubilis) Proteins.

Sacha Inchi (Plukenetia volubilis) oil press-cake (SIPC) represents a new source of proteins of high biological value, with promissory food applications. However, knowledge of these proteins remains limited. In this study, a Sacha Inchi protein concentrate (SPC) was extracted from the SIPC, and proteomic analysis was performed to identify the major alkaline-soluble proteins. The electrophoretic profile highlighted the efficacy of alkaline pH and moderate temperature to extract the major proteins, from which a group of proteins, not previously reported, were registered. LC-MS/MS analyses produced abundant high-quality fragmentation spectra. Utilizing the Euphorbiaceae database (DB), 226 proteins were identified, with numerous well-assigned spectra remaining unidentified. PEAKS Studio v11.5 software generated 1819 high-quality de novo peptides. Data are available via ProteomeXchange with identifier PXD052665. Gene ontology (GO) classification allowed the identification of sequenced proteins associated with biological processes, molecular functions, and cellular components in the seed. Consequently, the principal alkali-soluble proteins from SPC were characterized through derived functional analysis, covering 24 seed-storage-, 27 defense-, and 12 carbohydrate- and lipid-metabolism-related proteins, crucial for human nutrition due to their sulfur-containing amino acids, antioxidant properties, and oil yields, respectively. This research makes a significant contribution to the current understanding of the Sacha Inchi proteome and offers valuable insights for its potential applications in the food industry.

Evaluating sacha inchi (Plukenetia volubilis) oil stability and physicochemical properties: A comparison between conventional extraction and supercritical fluids

This study aimed to compare the effects of two extraction techniques (conventional n-hexane and supercritical CO2) on the oil extraction yields, fatty acids profile, anti-hyaluronidase activity, oxidative stability, and in vitro bioactivities of oils from Sacha Inchi (Plukenetia volubilis). Higher oil extraction yield (99 %) was achieved using the SC-CO2, although similar fatty acids profiles were depicted between both treatments (p < 0.05). The SC-CO2 oil presented higher anti-hyaluronidase (31 %) activity, but lower oxidative stability (5.05 h) compared to the solvent extraction (10 %, and 5.3 h, respectively). In vitro assays further revealed that the best human normal colon cells (FHC) cell viability (100 %), anti-inflammatory (50 % lower NO production), and antioxidant (20 % ROS reduction) activities were consistently observed in both extraction treatments at concentrations of 50 μg/mL and higher. These findings highlight the potential of supercritical CO2 extraction in yielding Sacha Inchi oil with enhanced bioactive properties without the disadvantages of the use of organic solvents extraction.

Effects of sacha inchi (Plukenetia volubilis) oil on the fatty acid profile, total polyphenols, antioxidant activity and sensory acceptability of dark chocolate granola bar

Sacha inchi (Plukenetia volubilis) oil is rich in polyunsaturated fatty acids (PUFAs) and antioxidants, providing essential health benefits to humans. Dark chocolate granola bar formulations enriched with sacha inchi oil were developed. In this study, sacha inchi oil (SIO) was added to a dark chocolate granola bar (DCGB) to replace butter at different percentages (0-10%). Four DCGB formulations were developed as follows: 0SIODCGB without sacha inchi oil (0%), which was used as a control sample, 2.5SIODCGB enriched with 2.5% SIO, 5SIODCGB enriched with 5% SIO, and 10SIODCGB enriched with 10% SIO. Next, the effect of SIO on the fatty acid profile, total polyphenols, antioxidant activity and sensory evaluation of DCGB were determined. The result showed that 10SIODCGB had the highest (p&lt;0.05) amount of PUFAs (28.14%) compared to 0SIODCGB (9.54%), 2.5SIODCGB (15.13%) and 5SIODCGB (25.32%). This study also showed that the total polyphenols and antioxidant activity of DCGB enriched with SIO formulations (2.5SIODCGB, 5SIODCGB and 10SIODCGB) were significantly higher (p&lt;0.05) than the 0SIODCGB. Regarding correlation, TPC and ferric reducing antioxidant power (FRAP) of the DCGB enriched with SIO were strongly related (r = 0.972). Meanwhile, the scores for sensory attributes of all DGCB formulations were similar (p&gt;0.05). Therefore, the enrichment of sacha inchi oil increased the polyunsaturated fatty acids, polyphenols and antioxidant activity in the formulated dark chocolate granola bar with well-accepted by consumers.

Formulation, Physicochemical, and Sensory Evaluation of Cookies Prepared from Sacha Inchi Oil Meal (SIOM)

Due to its substantial amounts of essential amino acids and protein, sacha inchi oil meal (SIOM) is ideal for producing protein-rich food. This study developed the cookies by blending SIOM with wheat flour at 5, 10, 20, and 30% (w/w), respectively. Physical properties, proximate composition, and sensory study were evaluated on the cookies. Data showed that 10% of wheat flour-SIOM cookies had the highest protein content (13.03%) compared to wheat flour cookies (4.89%). Cookies made with 20 and 30% SIOM were also feasible as the crude fiber content was high (48%). The hardness of wheat flour-SIOM incorporated cookies was lower (2.52–3.22 N) than wheat flour cookies (3.30 N). The water activity value of all the cookie samples during the 30-day storage was less than 0.6, indicating that the product was stable. Sensory analysis showed that the panelists preferred 10% SIOM-blend cookies over commercial cookies because of their better color, sweetness, texture, and appearance. Moreover, the overall acceptability of SIOM cookies was greater than 6 on a 9-point hedonic scale. This study concludes that SIOM can be a functional food ingredient that can help develop healthier bakery products.

Commercial Tara Protein: Functional properties and use to stabilize sacha inchi oil emulsions obtained by ultrasound

Commercial tara protein (CTP) and sacha inchi oil are promising Peruvian products for forming food emulsions. The present work aimed (1) to characterize the functional properties of CTP as a new protein source (water and oil absorption, foam, and gelling capacity) and (2) to deepen the CTP to form sacha inchi oil emulsions. The CTP (2%, 4%, 6%) and oil concentration (15%, 20% and 25%) were evaluated for rotor-stator (RS) emulsion production. Final emulsions (RS-US) were produced with RS emulsions added with 2% tara gum and ultrasound homogenization at 75% power amplitude for 3 min. Emulsions were analyzed according to gravitational stability, droplet size, and optical microscopy. The results showed that the CTP presented a centesimal composition of 6.03% moisture, 45.16% proteins, 12.32% lipids, 2.49% fiber, 6.04% ashes, and 27.96% carbohydrates. CTP had a greater oil absorption (2.1442 ±0.26 g/g solids) than water absorption (1.8201 ±0.02 g/g solids), did not present foam formation, and the least gelation concentration was 18%. RS-US emulsions prepared with 25% oil and 2% or 4% protein had greater stability against the creaming index and phase separation during 4h, despite emulsion prepared with 15% oil presenting the lowest mean droplet size. In conclusion, the results show that commercial tara protein effectively prepared emulsions with a combined method (rotor-stator, ultrasound, and tara gum).

Amazon Fruits as Healthy Ingredients in Muscle Food Products: A Review.

When looking for new ingredients to process red meat, poultry, and fish products, it is essential to consider using vegetable resources that can replace traditional ingredients such as animal fat and synthetic antioxidants that may harm health. The Amazon, home to hundreds of edible fruit species, can be a viable alternative for new ingredients in processing muscle food products. These fruits have gained interest for their use as natural antioxidants, fat replacers, colorants, and extenders. Some of the fruits that have been tested include açai, guarana, annatto, cocoa bean shell, sacha inchi oil, and peach palm. Studies have shown that these fruits can be used as dehydrated products or as liquid or powder extracts in doses between 250 and 500 mg/kg as antioxidants. Fat replacers can be added directly as flour or used to prepare emulsion gels, reducing up to 50% of animal fat without any detrimental effects. However, oxidation problems of the gels suggest that further investigation is needed by incorporating adequate antioxidant levels. In low doses, Amazon fruit byproducts such as colorants and extenders have been shown to have positive technological and sensory effects on muscle food products. While evidence suggests that these fruits have beneficial health effects, their in vitro and in vivo nutritional effects should be evaluated in muscle food products containing these fruits. This evaluation needs to be intended to identify safe doses, delay the formation of key oxidation compounds that directly affect health, and investigate other factors related to health.

All of the above constitutes a scientific novelty for Cuba, since it is the first time that Sacha Inchi is cultivated, industrial oil is obtained from its seeds and it is marketed in the country.

Application of Sacha Inchi Oil and Deterpenated Nutmeg Oil as Natural Antiaging in Facial Cream Formulation

Abstract Sacha inchi oil (Plukenetia volubilis L.) is rich in essential nutrients such as omega-3 fatty acids (α-linolenic acid), omega-6 (linoleic acid), omega-9 (oleic acid) and vitamin E (α-tocopherol and δ -tocopherol) which acts as a good skin barrier and reduces skin inflammation due to UV exposure. On the other hand, deterpenated nutmeg oil was reported to have antioxidant activity (IC50) stronger than native nutmeg oil. This study aims to utilize sacha inchi oil and deterpenated nutmeg oil as natural antiaging in facial cream formulations. Before used, sacha inchi oil is subjected to chemical glycerolysis to improve consumer acceptance. The physic-chemical properties between sacha inchi native oil and after pre-treatment were not significantly different. However, the hedonic test showed that the glycerolysis pre-treatment at 80°C had a better acceptance than native sacha inchi oil. The facial cream formulation used 5% sacha inchi oil and 1% deterpenated nutmeg oil with 1 – 5% niacinamide. All formulations showed oil in water (o/w) emulsion type. Facial cream with 5% niacinamide was the best formulation based on the hedonic test. It has a pH of 7.58, spreadability of 5.51 cm, and globule size of 7.11 μm

Co-Microencapsulation of Cushuro (Nostoc sphaericum) Polysaccharide with Sacha Inchi Oil (Plukenetia huayllabambana) and Natural Antioxidant Extracts.

Cushuro (Nostoc sphaericum) polysaccharide was used to co-microencapsulate sacha inchi oil, natural antioxidant extracts from the oleoresin of charapita chili peppers (Capsicum frutescens L.) and grape orujo (Vitis vinifera L.). Encapsulation efficiency, moisture, particle size, morphology, oxidative stability, shelf-life, solubility, essential fatty acid profile, sterol content and antioxidant capacity were evaluated. The formulations with grape orujo extract showed higher oxidative stability (4908 ± 184 h), antioxidant capacity (4835.33 ± 40.02 µg Trolox/g ms), higher phenolic contents (960.11 ± 53.59 µg AGE/g ms) and a smaller particle size (7.55 µm) than the other formulations, as well as good solubility and a low moisture content. Therefore, grape orujo extracts can be used as natural antioxidants. The fatty acid composition (ω-3) remained quite stable in all the formulations carried out, which also occurred for sterols and tocopherols. In combination with gum arabic, grape orujo extract offered oxidative protection to sacha inchi oil during the first week of storage.

Effects of Sacha Inchi (Plukenetia volubilis) Oil on Serum Interleukin 6 Levels and Foam Cell Count in Male Wistar Rats (Rattus norvegicus) Fed a High Fat and Fructose Diet

A high-fat, high-fructose diet induces pro-inflammatory agents such as Interleukin-6 (IL-6) and hyperlipidemia, leading to atherosclerosis. Sacha inchi oil, rich in alpha-linolenic acid (ALA), has anti-inflammatory and lipid-modulating properties. This study aimed to examine the effect of sacha inchi oil on serum IL-6 levels and foam cell count in the aorta of wistar rats on a high-fat, high-fructose diet. This experiment is a true experimental study with a post-test-only control group design, 30 male wistar rats were divided into five groups: normal control (K0), high fat and fructose diet (HFFD) (K1), and three treatment groups receiving HFFD with sacha inchi oil at doses of 0.27 ml/200gBW/day (P1), 0.54 ml/200gBW/day (P2), and 1.08 ml/200gBW/day (P3) for 28 days. On day 29, serum IL-6 levels were measured using ELISA. Mean serum IL-6 levels were K1 (8.465 ng/L), P1 (4.294 ng/L), P2 (3.197 ng/L), P3 (1.379 ng/L), and K0 (1.340 ng/L), with significant differences among groups (p&lt;0.05) except between K0 and P3 (p&gt;0.05). Mean foam cell counts were K1 (55.3 cells/fov), P1 (47.1 cells/fov), P2 (53.2 cells/fov), P3 (52.6 cells/fov), and K0 (44.4 cells/fov), with significant differences between K0 and K1, K1 and P1, K0 and P2, and K0 and P3 (p&lt;0.05). Sacha inchi oil significantly reduced IL-6 levels at all doses compared to the negative control (p&lt;0.05), with the 1.08 ml/200 g/day dose being most effective. The 0.27 ml/200 g/day dose inhibited foam cell formation in HFFD rat. In conclusion, sacha inchi oil reduces serum IL-6 levels and inhibits foam cell formation in male wistar rats on a high-fat, high-fructose diet.

Stability, chromatic characteristics and chemical changes of sacha inchi (Plukenetia huayllabambana) oil enriched with aguaje oil (Mauritia flexuosa L.f.) rich in carotenoids

Sacha inchi (Plukenetia huayllabambana) oil is a food matrix that contains more than 80 % of polyunsaturated fatty acids, especially linoleic and α-linolenic acids. The objective of this study was to develop blends of sacha inchi oil (P. huayllabambana) enriched with aguaje oil (Mauritia flexuosa L.f.) and evaluate the induction period, total carotenoid content, nutritional quality indices and oxidative stability from the fatty acid composition. The analytical tests were conducted for oil blends that had the following proportions: sacha inchi oil enriched with aguaje oil at 5, 10 and 20 %. The results prove that the enrichment of sacha inchi oil with aguaje oil (SIO-PH-AO) leads to an improvement in oxidative stability and nutritional and physical properties. For example, the oxidative stability index (OSI) varied from 0.87 to 2.53 h. The content of total carotenoids produces an increase from 0.35 to 99.90 mg/kg, while total polyphenols from 47.45 to 126.90 mg GAE/g, and chroma from 39.91 to 69.02 units. Regarding the fatty acid profile, the oxidizability value improves with the addition of aguaje oil. Reduces levels of PUFA, PUFA/SFA, and hypo-and hypercholesterolemic ratio (h/H). Additionally, an increase in SFA and MUFA levels, while the ω6/ω3 ratio remained constant. Finally, it can be noted that the enrichment of sacha inchi oil with aguaje oil (rich in carotenoids) provides better stability and can be used for commercial applications as a mechanism to establish new vegetable oils with better properties.

Effect of Sacha Inchi Oil on Human Blood Pressure and Lipid Profile: A Preliminary Study in Malaysia

This uncontrolled pre-post study aimed to assess changes in blood lipid profiles and blood pressure resulting from a 2-month consumption of Sacha Inchi Oil (SIO) (Plukenetia volubilis). Investigating the effects of SIO on Malaysians is essential for tailoring interventions to the local context, considering genetic, cultural, and dietary differences. A total of 13 adult participants, comprising 8 males and 5 females aged 35 to 74 years old, took part in this intervention study. Each participant was instructed to consume 2 softgels daily, with each softgel containing 530 mg of SIO. Blood lipid profiles and blood pressure were measured at baseline and at the end of the 2-month period, utilizing venipuncture for blood tests and a sphygmomanometer for blood pressure assessment. The results indicated a significant reduction in Systolic Blood Pressure (SBP) levels following SIO supplementation (2 softgels daily) (p&lt;0.05). However, there were no notable improvements in Diastolic Blood Pressure (DBP), Total Cholesterol (TC), Low-Density Lipoprotein Cholesterol (LDL-C), High-Density Lipoprotein Cholesterol (HDL-C), and Triglycerides (TG) after the 2-month supplementation. In conclusion, the daily supplementation of 2 softgels of SIO (1,060 mg) for 2 months demonstrated a beneficial effect on blood pressure, particularly in reducing SBP. These findings serve as preliminary data for future research into the potential health benefits of SIO in the Malaysian population.

The functional viability in the use of herbal medicine as an alternative to the pharmacological treatment of dyslipidemia: Asystematic review

Background: Dyslipidemia is caused by an increase in plasma lipoprotein levels and predisposes to the risk of thrombotic events, which highlights the need for early treatment. Traditional therapies have limitations due to the lack of adequate responses and abandonment of treatment due to its adverse effects. Aim: This study sought to identify alternative treatments for dyslipidemia using herbal medicines, which could help traditional methods or replace them. Methods: A systematic review was carried out by searching the Latin American and Caribbean Literature in Health Sciences (Lilacs), PubMed and ScienceDirect databases using the descriptors "phytotherapy" OR "phytotherapeutic drugs" AND "dyslipidemias" OR "cholesterol" OR "atherosclerosis". Results: The databases returned 80 articles, 9 were excluded for being duplicates and after applying the exclusion and inclusion criteria resulted in a sample of 13 articles. Studies with herbal medicines such as Red Grape Seed Extract (RGSE), Sacha Inchi Oil, Green Tea, Eggplant Juice, Agrimonia eupatoria, Artichoke and Garlic, which showed different effects on lipid profiles, were evaluated. Conclusion: The use of herbal medicines in the treatment of dyslipidemia may be a viable alternative, but further studies are needed on this subject.

Fish Burgers Fortified with Microencapsulated Sacha Inchi Oil: Effects on Technological and Sensory Properties.

The long-chain omega-3 fatty acids alpha linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) have proven health benefits, but it is not common to find them together in a processed food product. This could lead to healthier and more functional food products, which may have positive implications for consumer health and well-being. This work aimed to fortify a model burger manufactured with fillets of an Amazonian fish (boquichico, Prochilodus nigricans) by adding microencapsulated sacha inchi oil (Plukenetia volubilis, rich in ALA) (MSIO) produced by spray-drying. MSIO was incorporated into the burgers at different levels (0, 3, 4, 5, and 6%). The burgers were characterized by their proximal composition, cooking losses, texture profile, lipid oxidation, sensory profile, overall liking, and fatty acid profile. The results showed that adding MSIO up to concentrations of 5% or 6% increased the instrumental hardness, chewiness, and lipid oxidation in the burgers. However, fortifying the burgers with 3% MSIO was possible without affecting the burgers' sensory properties and overall liking. Regarding the fatty acid profile, the burgers with 3% MSIO had a higher content of polyunsaturated fatty acids, with the ALA, EPA, and DHA types of fatty acids. Therefore, we recommend using this fortification concentration, but future studies should be carried out to improve the oxidative stability of MSIO and the burgers.

Sustainable Ultrasound-Assisted Extraction and Encapsulation of Phenolic Compounds from Sacha Inchi Shell for Future Application

Sacha inchi shell (SIS), an underutilized by-product of sacha inchi oil processing, is a rich source of phenolic compounds. In this study, ultrasound-assisted extraction (UAE) was optimized by response surface methodology (RSM) with a Box–Behnken design to investigate the effects of time (15–25 min), temperature (25–45 °C), and ethanol concentration (40–80%) on the total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity by DPPH assay of the obtained extracts. The maximum TPC was at 15 min, 45 °C and 60%, TFC at 25 min, 45 °C and 60% and DPPH at 15 min, 35 °C and 80%. The optimized condition selected for encapsulation purposes was at 25 min, 35 °C and 80% ethanol concentration. RSM analysis showed that all models analyzed for all three assays were significant at 95% confidence. The SIS extract had a greater inhibitory zone against Escherichia coli measuring 15.34 mm at a concentration of 30 µg/mL than Staphylococcus aureus among the samples. The spray-dried microcapsules using different combinations of gum arabic and maltodextrin (GMM 1 and GMM2) resulted in a proper encapsulation layer and a smoother surface and shape obtained at 1000× magnification. Also, GMM 1 and GMM2 had particle sizes ranging from 2.95 ± 0.02 to 27.73 ± 0.38 and from 5.20 ± 0.01 to 29.30 ± 0.42 µm, respectively. The microcapsules were in the acceptable ranges for moisture content (&lt;5%) and water activity (&lt;0.6). It has been concluded that SIS extract showed high antioxidant and antimicrobial properties and its encapsulation could be further used in food and nutraceutical formulations.

Enzymatic synthesis of structured lipids from sacha inchi (Plukenetia volubilis) oil with capric acid via acidolysis reaction in stirred tank and packed bed mini reactors

The present study describes an efficient and sustainable synthesis method for producing functional triglycerides (FTs) by conducting an acidolysis reaction of sacha inchi (Plukenetia volubilis) oil with capric acid (C10), catalyzed by Rhizopus oryzae (RO) lipase immobilized in low-cost corn cob powder, to obtain medium-large-medium chain (MLM) triglycerides. Initially, acidolysis reactions were performed between sacha inchi oil, C10, and the immobilized enzyme in a stirred tank at various temperatures (35 °C, 45 °C, 55 °C, and 59 °C), different molar ratios (1:2, 1:3, 1:4 oil:fatty acid), and various hydrolytic enzyme activities (83.6, 124, and 217 IU/mg). Subsequently, to optimize the degree of incorporation, the best condition from the stirred tank reactions (45 °C, 1:3 M ratio, and 217 U of hydrolytic activity) was selected, considering the highest nutritional quality of the lipid in terms of the migration of the sn2 position, and was tested in a packed bed reactor with a spatial time of 112 min, residence time of 107 min, and a flow rate of 0.5 mL/min. The highest incorporation degree achieved in packed bed reactor was 36% at 45 °C. Afterward, it was developed for the best condition an integrative platform for the recycling of the RO lipase immobilized in low-cost corn cob powder (up to four successive cycles without any make up). Subsequent assays on the functional triglycerides revealed atherogenic and thrombogenicity lipid index values of 0.04 ± 0.10 and 4.15 ± 0.05, respectively, which were lower than those of pure sacha inchi oil, indicating the potential to enhance the nutritional quality of the oil through C10 incorporation.

Cold-Pressed Sacha Inchi Oil: High in Omega-3 and Prevents Fat Accumulation in the Liver.

The ability of oil supplementation to inhibit various metabolic syndromes has been recognized. However, there are currently no studies determining the effects of oil supplements on healthy conditions. Plukenetia volubilis L., also known as Sacha inchi, is a seed rich in essential unsaturated fatty acids that improves metabolic syndrome diseases, such as obesity and nonalcoholic fatty liver. However, the health benefits and effects of Sacha inchi oil (SIO) supplementation remain unclear. This study aims to evaluate the chemical effects and properties of Sacha inchi oil. The results of the chemical compound analysis showed that Sacha inchi is an abundant source of ω-3 fatty acids, with a content of 44.73%, and exhibits scavenging activity of 240.53 ± 11.74 and 272.41 ± 6.95 µg Trolox/g, determined via DPPH and ABTS assays, respectively, while both olive and lard oils exhibited lower scavenging activities compared with Sacha inchi. Regarding liver histology, rats given Sacha inchi supplements showed lower TG accumulation and fat droplet distribution in the liver than those given lard supplements, with fat areas of approximately 14.19 ± 6.49% and 8.15 ± 2.40%, respectively. In conclusion, our findings suggest that Sacha inchi oil is a plant source of ω-3 fatty acids and antioxidants and does not induce fatty liver and pathology in the kidney, pancreas, and spleen. Therefore, it has the potential to be used as a dietary supplement to improve metabolic syndrome diseases.

Reduction of Saturated Fat in Dark Chocolate using Sacha Inchi (Plukenetia volubilis) Oil Oleogel

This research studied the effectiveness of Sacha Inchi Oil Oleogel (SIOO) as a partial replacement for saturated fat in dark chocolate. Sacha inchi (Plukenetia volubilis) oil is high in polyunsaturated fatty acids (α-linolenic and linoleic acids) and a good source of tocopherols. This study prepared oleogels using sacha inchi oil as a base oil and food-grade beeswax as an oleogelator. Different percentages of SIOO (1%, 2.5% and 5.0%) were added in the dark chocolate. Dark chocolate without SIOO was used as a control. Fatty acid profile, total polyphenols, antioxidant activity and sensory evaluation of the formulated dark chocolates with SIOO were investigated. The incorporation of SIOO significantly (p&lt;0.05) lowered the saturated fat and increased the polyunsaturated fatty acids in dark chocolate samples. This study also showed that the total polyphenols and antioxidant activity of dark chocolates enriched with 2.5 and 5.0% SIOO were significantly higher (p&lt;0.05) than the other chocolate samples. Sensory evaluation showed that control and dark chocolates added with SIOO (1% and 2.5%) received similar scores for all sensory attributes. However, the highest concentration of SIOO decreased significantly (p&lt;0.05) the scores for the taste and overall acceptability of dark chocolate. Therefore, the enrichment of sacha inchi oil oleogel as a functional ingredient could reduce the saturated fat and increase the polyunsaturated fatty acids and antioxidant activity of the formulated dark chocolate, which is well-accepted by consumers.
