| 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... |

| ABSTRACT The objective of this study was to use different parts of the Tithonia tubaeformis plant in feed for fattening rabbits and then observe the effects on carcass and meat quality. Forty-eight weaned rabbits (35 days of age) were randomly assigned to four groups (n = 12 by treatment). Animals were fed ad libitum a control diet as well as three experimental diets, with addition of Tithonia tubaeformis leaves, whole plant, and stems. Rabbits were slaughtered after 63 days of age without fasting. Results indicate that live weight (0.917), skin (0.79), feet (6.679), and lumbar circumference of the carcass (0.707) have higher positive correlations with hot carcass. There were no significant differences between treatments for all variables measured, except... |

| The freezing raw whole lobster is one of the products that are commercialized in the outer market; nevertheless the main factor that causes its rejection is the mass texture. Nodarse et al. (2005) determined that this product stayed with very good characteristics for its exportation until 10 months, after this period it began to detect a softening of the mass. There are different methods to determine the food texture, which is grouped in sensorial and instrumental. The objective of the present work was to determine the sensorial and instrumental texture of this product. Five raw whole lobsters by duplicate with different time storage (6, 8, 10, 12, 14 months) were evaluated using for it a paired comparison test. In order to measure the product firmness. It... |

| Crustaceans are harmed rapidly due to the post mortem different processes, specially the dark spot knew as melanosis or enzymatic darkening. Those spots are controlled by the sulfite treatments, but the potential dangers associated with the use of these compounds oblige to develope rigorous control methods. Besides, in these species are observed texture affectations during the storage time, changing to pasty mass and reducing its commercial quality. For these reasons, it was realized a durability study, analizing chemical, microbiological and sensorial parameters to the frozen products raw lobster tails and tail mass. The results indicated a shelf life of 21 months for the lobster tails and 18 months for the tails mass. |

| Milk calcium concentration is a factor related to cheese texture, an important rheological property of cheese quality as perceived by consumers. This study aimed to evaluate the effect of different pH conditions (5.8 and 6.6) and calcium addition (0, 150, 300 ppm of CaCl2), on yield and nutrient retention of the clots obtained and on the texture of Minascured cheese. Clots were analyzed for wet and dry yield, percentage content and retention of protein, fat and calcium. The texture of the cheese was evaluated by instrumental and sensorial tests. No differences were observed on the wet and dry yields, or on the protein content, fat and calcium retention of clots produced in the different experimental conditions. The instrumental evaluation showed that... |

| Different methods in use for cold smoking of salmon affect product yield and quality. The combinations of filleting time (pre or post), salting methods (dry or injection), salting targets (2.5 or 4%) and smoking temperatures (15 or 25 °C) were studied during 6 weeks of 4 °C cold storage. Salting method had the greatest influence on flesh quality. Injection salting led to 15% higher fillet yield, moderate to strong gaping score, softer texture, and paler fish compared with dry salting. Pre-rigor filleting reduced fillet gaping from a moderate to minor score, but only in dry salted fillets. Smoking at 15 °C reduced yield by 0.5% in injected salted fish, compared with 25 °C. The combination of pre-rigor filleting, dry salting and 15 °C smoking temperature... |

| ABSTRACT This study aims to evaluate the possibility to formulate low-sodium bicarbonate-marinated turkey breast meat. In total, 60 meat cuts (100 × 50 × 30mm) were divided into four treatments: B1 (0.5% sodium bicarbonate and 0% sodium chloride replacement), B2 (0.5% sodium bicarbonate and 15% sodium chloride replacement), B3 (0.5% sodium bicarbonate and 30% sodium chloride replacement), and B4 (0.5% sodium bicarbonate and 45% sodium chloride replacement). The results showed that sodium replacement up to 45% had no impact on texture (as represented by Allo-Kramer shear values) and water activity. After cooking, Group B1 exhibited the highest L* value (72.1) and the lowest b* (6.6) when compared to other groups. In conclusion, replacing sodium chloride... |

| The objective of this study was to evaluate the inclusion of minced fish (MF) (0, 20, 40, 60, 80 and 100%), obtained from Nile tilapia filleting waste, in sausage and determine their physicochemical, nutritional and sensory properties. The sausages showed a decrease in protein and increase in fat content with increasing inclusion of MF. The nutritional quality of the products was high, with digestibility over 85%. The parameters of texture instrumental and yellow color (b*) decreased with the increasing inclusion of MF. The sensory evaluation of the color showed that the maximum level of inclusion of MF was not well accepted by the panelists. The sausage with the best acceptance for the flavor attribute was those with 60% of MF. The results showed good... |

| En el presente trabajo se presentan los resultados de la precisión de diferentes técnicas empleando una máquina Instron para medir la textura de spaghetti seco. Se comparó la técnica de flexión o doblado con los métodos que utilizan la celda de Kramer y la cuchilla simple de Warner-Bratzler. Se concluyó que en todos los casos las técnicas presentan buena precisión, pero el método de flexión ofrece los mejores resultados, con la ventaja adicional de que puede calcularse la fuerza de fractura en tensión como propiedad mecánica fundamental que caracteriza el producto. |
