NUTRIALBÓNDIGAS

Blázquez Ortega, Juan Francisco, Espinoza Roque, Gianmarco, Garcia Carlos, Yamile Alexandra, Garcia Ordinola, Andy Manuel, Paredes Jarrin, Alejandra 04 December 2020 (has links)
La presente investigación busca validar la viabilidad de un nuevo producto que se planea lanzar al mercado peruano. Este producto posee el nombre de Nutrialbòndigas elaborado por la empresa KayPachaFoods. Asimismo, está compuesto por dos insumos principales; la quinua y el camote, ambos brindan un alto contenido de nutrientes, vitaminas y minerales. Para la idea de negocio, se realizaron diversas investigaciones previas y diversos prototipos para llegar al producto final, albóndigas naturales sin preservantes ni gluten. Con la información obtenida por las investigaciones se determinó que el mercado objetivo son las personas que residen en Lima Metropolitana, de las zonas geográficas 6 y 7 de los NSE A, B y C. Debido a que se preocupan por su salud, estado físico y están dispuestos a probar innovadoras presentaciones de productos tradicionales. Finalmente, luego de haber comercializado las Nutrialbóndigas se obtuvieron recomendaciones para que a lo largo del proyecto se produzcan constantemente mejoras en el producto. De igual manera, los usuarios se mostraron satisfechos con el producto brindado. / The current investigation looks forward to make visible the new product which is planning to be launched to the Peruvian market. This product name is “Nutrialbondigas” elaborated for KayPachaFoods company. In addition to this, is composed of two main inputs: Quinoa and Sweetpotato, both shows a higher nutrients content such as vitamins and minerals. On the other hand, the business plan was necessary many previous investigations and several prototypes to reach the final product, natural meatballs no added preservatives and gluten free. With this information as a result from the previous investigation it is concluded that objective market are people who lives in Metropolitan Lima, from geographics zone 6 and 7 of NSE A, B and C. Because this are the population who cares about their health and physical condition, and they are willing to prove our new presentation from the traditional products. Finally, after having commercialized the Nutrialbóndigas, recommendations were obtained so that throughout the project there are constant improvements in the product. Furthermore, users were satisfied with the product provided. / Trabajo de investigación

Förändringar av kvalitetsparametrar i frityrolja vid tillagning av köttbullar : Examensarbete i Kemi 15 hp / Changes in quality parameters in frying oil when used for frying meatballs : Degree project in chemistry 15 hp

Lendrop, Linnéa January 2020 (has links)
Detta arbete undersöker förhållandet mellan kvalitetsparametrar i frityrolja, såsom halten fria fettsyror (FFA), anisidinvärdet (AV) och %TPM (Total Polar Materials) samt Agtronvärdet hos köttbullar efter fritering. Kvalitetsparametrar hos frityrolja, såsom primära och sekundära oxidationsprodukter, kan mätas för att utvärdera oljans kvalitet då nivåerna ofta ökar i samband med oljans användning. Primära oxidationsprodukter, såsom peroxider, kan mätas med hjälp av ett så kallat peroxidvärde (PV) och sekundära oxidationsprodukter, såsom aldehyder, kan mätas med hjälp av anisidinvärdet. Analys av %TPM och FFA är exempel på andra metoder för att mäta kvaliteten hos en olja då polariteten ökar i takt med oljans användning. Halten FFA i oljan undersöktes med hjälp av titrering med natriumhydroxid och %TPM mättes med hjälp av mätinstrumentet Testo 270. Agtronvärdet hos köttbullarna mättes med hjälp av instrumentet Agtron E30FP, som använder IR-teknologi för att bestämma färgen på en produkt. Resultaten visade att halten FFA, AV och %TPM i frityroljan ökade med tiden under samtliga fyra produktionsdagar. Hypotesen att produkten bör vara mörkare, det vill säga att Agtronvärdet bör vara lägre vid produktionens slut jämfört med början stödjs av resultaten från två av fyra produktionsdagar. Slutsatsen drogs att det fanns skillnader i oljans sammansättning, med hänsyn till FFA, AV och %TPM vid produktionsdagens slut jämfört med start. Däremot kunde ingen tydlig koppling ses mellan dessa förändringar och en minskning av Agtronvärdet hos köttbullarna över tiden. Ytterligare studier behövs således för att kunna dra en slutsats kring sambandet mellan kvalitetsparametrar i frityrolja och färgen på det friterade livsmedlet. / This study examines the relationship between quality parameters of frying oil, such as Free fatty acids (FFA), the Anisidine Value (AV) and Total Polar Materials (%TPM), as well as the Agtron Value of meatballs after deep frying. Quality parameters in frying oil, such as primary and secondary oxidation products, measure the quality of the frying oil since levels increase with the use of the oil. Primary oxidation products, such as peroxides, can be measured by the Peroxide Value (PV) and secondary oxidation products, such as aldehydes, can be measured by the Anisidine Value. Analysis of %TPM and FFA are other methods to measure the quality of an oil, since the polarity increases as the oil is used for frying. The instrument Testo 270 was used to measure %TPM in the oil and FFA was determined by titration with sodium hydroxide. The Agtron E30FP instrument was used to determine the Agtron Values of the meatballs, wich used IR technology to determine the color of the product. Results showed that the FFA, AV and %TPM of the oil increased over time in all four production days. It was expected that the product should be darker, that is, the Agtron Value should be lower at the end of production compared to the beginning, but this was only seen in two out of four production days. It was concluded that there are differences in the composition of the oil, with regard to FFA, AV and %TPM at the end of the production day compared to the beginning of the day, but no clear connection was seen between these changes and a decrease in the Agtron Value of the meatballs over time. Further studies are needed to be able to draw a conclusion about the relationship between quality parameters of frying oil and the color of the fried food.
