The aim of this research was to evaluate the phytochemical and nutraceutical profiles of Cyclanthera pedata fruits, a native fruit of the Andean region used by Incas communities called achojcha. Soluble protein (SP), total sugar (TS), free phenolic compounds (FPC), ascorbic acid (AA), total monomeric anthocyanin (TMA), condensed and hydrolizable tannin (CT, HT) were evaluated by sprectrophotometric methods in fresh fruits with and without heating and in flour obtained from fruits. Multielemental composition by ICP-MS was done. Antioxidant activity (AOA) was determined by ABTS and Linoleic acid-b-carotene methods. The inhibitory capacity of LOX, a pro-inflammatory enzyme was also analyzed. The achojcha fresh fruits and achojcha flour showed low amount calories. The flour was high in potassium (7400 mg·K/100 g) and low in sodium (77 mg Na/100 g). High levels of FPC (670 mg GAE/100 g) were found together with elevated levels of AA (123 mg AA/ 100 g). The TMA (0.6 mg C3-GE/100 g) as well as HT (3.4 mg PB2E/100 g) were also detected in flour. All preparations obtained with fresh and dried fruits showed AOA with SC50 values between 1.8 to 14.5 μg GAE/mL. Inhibitory capacity on LOX was also demonstrated (IC50 values of 40 μg GAE/mL). The fresh fruits and flour showed nutraceutical characteristics that are demanded by functional food and could be used as dietary supplement.展开更多

Guayaba is a fruit highly perishable and susceptible to damage during the postharvest. One strategy to overcome this problem is its processing by using techniques that preserve its organoleptic, nutritive and functional properties and allow getting food with added value. The purpose of this study was to obtain flour from fresh fruits cultivated in Argentina Northwestern by lyophilization and to determine the antioxidant activity and the main phytochemicals present in fresh fruits and flour. Nutritional composition (sugar, protein and fat) and the bioactive phytochemicals (total phenolic compounds, flavonoid phenolic, condensed and hydrolizable tannin, ascorbic acid, pigments such as anthocyanin and carotenoids) as well as fiber content, were evaluated. The flour preserved flavor, aroma and color of pulp from fresh fruits. The flour contained around 30% of sugar, 20% of total protein, 0.5% of fat and high level of crude fiber. Carotenoids and ascorbic acid were the dominant phytochemicals in flour as well as in fresh fruits. The guayaba flour showed antioxidant activity with SC50 values similar to fresh fruits. The flour showed nutraceutical characteristics that are demanded by functional food and could be used as a dietary supplement.展开更多

Soluble protein (SP), total sugar (TS), free phenolic compounds (FPC), ascorbic acid (AA), total monomeric anthocyanin (TMA), condensed and hydrolizable tannin (CT, HT) and carotenoids (C) were determined by spectrophotometric methods. Multielemental composition by ICP-MS was also done. The flour showed low amounts of calories and high potassium and low sodium levels. Flour from “locoto” fruits contained mainly carotenoids (0.82 to 20 g Eβ-C/100g DW), polyphenolic compounds (681 - 822 mg GAE/100g DW) and ascorbic acid (100 - 199 mg AA/100g DW). The polyphenolic profile of Lcp was similar to flour obtained in our laboratory but the level of carotenoid was lower than that of flour. The fiber content of flour was around 3% in all cases. All preparations obtained from flour and Lcp showed antioxidant activity with SC50 values between 1.4 and 3 μg GAE/mL. Inhibitory capacity on Lipo-oxygenase enzyme was also demonstrated. Non mutagenic effect was detected. The “locoto” flour showed nutraceutical characteristics that are demanded by functional food and could be used as a dietary supplement.展开更多

PCA identified eight significant principle components, that reduce the size of the variables into one principal component in physiochemical analysis interpreting 73.5% of the total variability with/and 78.6% of total variability explained in sensory evaluation. Score plot indicates that Double Bean milk chocolate in-corporated with MOL and CML in nutritional profile have high positive correlations. In nutritional evaluation, carbohydrates and fat content shows negative/minimal correlations whereas no negative correlations were found in sensory evaluation which implies every sensorial variable had high correlation with each other.展开更多
