Abstract The effects of replacing cocoa butter with different percentages and proportions of a mango kernel fat/palm olein (MKF/POL) blend, are reported. Samples were prepared by melting together mango kernel fat, palm olein, cocoa butter and cocoa mass and powdered sugar combinated. The samples were milled, conched, tempered, and molded to obtain three sets of seven samples as follows: one control omitting mango kernel fat and palm olein, and six samples with cocoa butter replacement of 15 and 22.5% and MKF/POL ratios of 2.3, 4.0, and 9.0. Casson viscosity, Casson yield stress, fat bloom and sensory acceptability were all measured. In fact, all samples had achieved a low Casson viscosity (ηCA) and Casson yield stress ( τ oCA ), which indicates molding and...

Abstract The goals of this paper were to evaluate total polyphenol content (TPC), total flavonoid content (TFC), anti-oxidant capacity (AC) and reducing power (RP) of eight dark chocolates that are sold in Peru. Imported and domestic chocolate samples containing between 50% and 74% cacao were defatted. Defatted chocolate (DCh) was separated and treated to extract phenolic compounds. The TPC and AC were determined by using the Folin-Ciocalteu reagent and two in vitro models based on the free-radical capturing capacity DPPH and ABTS. The RP was evaluated by using the potassium pherricyanide method; in the TFCs assessments, catechin was used as the standard. Chocolate TPC varied between 1.69 ± 0.02 and 5.39 ± 0.17 mg gallic acid/g chocolate and AC (DPPH-IC50)...

Assessment of physical and physicochemical quality of main chocolates traded in Peru
Provedor de dados: 109
Autores: Chire-Fajardo,Gabriela Cristina; Valdivia-Arrunategui,Rocío Alicia; Orihuela-Rivera,Carmen Adela; Ureña- Peralta,Milber Oswaldo.
Abstract: The quality of the main chocolates marketed in Peru was determined. The physical aspect: color (C *, H *, IB), hardness and particle size, as well as physicochemical: water activity (aw), moisture, fat and ash, correlating with the declaration of ingredients presented in the packaging. We evaluated 30 experimental units of chocolates (imported, domestic, dark chocolate and milk) by experimental methods, randomly acquired from different establishments. The difference between color and hardness by origin was attributed to the dairy component. Dark chocolate had lower values of color components (8.75 ± 0.94 C *, 7.60 ± 4.71 H * and 28.46 ± 0.86 IB) than milk constituents (15.04 ± 2.78 C, 34.59 ± 7.46 H * and 34.55 ± 2.87 IB) and in hardness values...
