The current food industry drives interest in foods that not only satisfy basic needs, but also promote health. In this context, yacon, with its fructooligosaccharides (FOS)-rich syrup, emerges as a valuable plant source for improving the properties of bread. This study evaluated the effects of FOS addition from yacon on the physicochemical and sensory characteristics of bread. A traditional methodology involving bread making with different concentrations of the syrup was employed. The results revealed that the treatments with 0.5% and 1.5% yacon syrup excelled in bulk density, crumb cell shape and crumb appearance. In the sensory evaluation, the 0% and 0.5% treatments scored best in crust colour, texture and flavour. In conclusion, the addition of FOS to bread was shown to significantly improve its physicochemical and sensory characteristics: the addition of 1.5% and 0.5% improved bread ...

The impact of temperature and air velocity on the drying of pituca (Colocasia esculenta) sheets was investigated. The samples, 1.5 mm thick, were subjected to a tray dryer at three temperatures (45, 50 and 55 °C) and three air velocities (2.5; 3.0 and 3.5 m/s). After grinding the dried sheets, the physicochemical, microbiological and sensory properties of the pituca flour were analyzed. The findings indicated that the drying curves conformed to the exponential model proposed by Herdenson and Pabis, with a coefficient of determination greater than 96%. The optimum treatment, T9, used a temperature of 55 °C and a speed of 3.5 m/s. It showed a critical moisture of 1.53 g/g dry pituca, an equilibrium moisture of 0.9 g/g dry pituca, and a critical time of 20 minutes. Values for ash, moisture, mesophilic aerobes, molds and yeasts were recorded at 3.37%, 8.04%, 9.90x103 CFU/g, and 2.40x103 ...

Sensory evaluation of food is a constantly evolving field, where recently developed analysis methods are on their way to be consolidated. Check-All-That-Apply (CATA) is a rapid method used to describe sensory characteristics of a product through a personalized selection of terms; however, the format in which these terms are presented is not standardized. This study aimed to assess the effect of the design of four CATA ballots for the analysis of strawberry drinkable yogurt. Fifteen descriptive terms were established with the participation of 97 consumers, with 6 terms relating to texture, 5 to taste, and 2 to both appearance and odor. The four ballot models: a) columns, b) vertical list, c) radial distribution, and d) random distribution, were applied to characterize the same commercial brand of yogurt using 150 consumers for each model. According to Cochran’s Q test, significant diffe...

The nutritional and sensory characteristics of food products are important for their acceptance by the consumer. The objective of this research was to evaluate cookies fortified with cushuro and tarwi, two ingredients that stand out for their nutritional properties and potential health benefits. Cushuro, an algae that grows in high-altitude lakes in the Andes, is important for being an excellent source of proteins, vitamins, and minerals such as iron and calcium. On the other hand, tarwi, an Andean legume, is rich in proteins, fiber, and fatty acids, making it a highly nutritious food. The idea of fortifying cookies with cushuro and tarwi arises from the seek for alternatives to enhance the nutritional content of processed foods. Given that cookies are widely consumed, especially by children and adults, incorporating nutrient-rich ingredients like cushuro and tarwi can significantly cont...

This study aims to enhance product quality from a production perspective, due to the detection of bisphenol A (BPA), a compound that directly impacts final consumers. In response to this issue, a modification was implemented in the production process to eliminate BPA. Potential suppliers for a new varnish were considered, and three of them offered BPA-free options. A control sample was compared with these options over eight months, corresponding to the shelf life of canned milk at the point of sale. Ultimately, the supplier that offered the varnish with the least variation and preserved the product’s properties was chosen. The results were validated using relevant statistical tests based on data normality. In conclusion, evaluating the parameters related to product quality made it possible to identify the ideal supplier to replace the varnish in the production chain without affecting p...
