Abstract This article explores the historiography of two historians linked to the IHGRGS , at different times of the institution’s existence. Docca, acting as one of the founding partners, and Vellinho, writing at a decisive moment of the Institute. Both of them played a role in the project of writing an official history that aimed to incorporate Rio Grande do Sul into the national whole, territorially as well as culturally. Our goal is to understand how, even writing at different times, and with emphasis on different themes, both authors maintain the lusitanist bias defended by the IHGRGS in their writing of history.

Resumen El presente artículo está enfocado en la escritura de dos historiadores vinculados al Instituto Histórico y Geográfico de Rio Grande do Sul (IHGRGS ) en diferentes momentos de la existencia de dicha institución: Docca, uno de sus miembros fundadores y, más tarde, Vellinho, que escribió en un momento decisivo del Instituto, durante un proceso de reorientación regionalista. Ambos convergieron en el proyecto de escribir una historia oficial, que pretendía integrar Rio Grande do Sul al “todo” nacional, tanto en lo territorial como en lo cultural. Nuestro objetivo es entender cómo, aunque escribieron en épocas diferentes y pusieron énfasis en temas distintos, ambos autores discutieron sobre sus temas sin perder cierto cariz lusitanista que el IHGRGS defiende para la escritura de la historia.

Resumo O presente artigo toma como objeto a escrita da história de dois historiadores vinculados ao IHGRGS , em momentos diferentes da existência da instituição. Primeiramente, Docca, atuando como um dos sócios fundadores e, posteriormente, Vellinho, escrevendo num momento decisivo do Instituto, em meio à reorientação regionalista que este conheceu, corroboram com o projeto de escrita de uma história oficial, que objetiva incorporar o Rio Grande do Sul ao todo nacional, tanto territorial quanto culturalmente. Nosso objetivo é perceber como, mesmo escrevendo em momentos diferentes, e com ênfase a diferentes temáticas, ambos os autores discorrem sobre seus temas mantendo o viés lusitanista defendido pelo IHGRGS em sua escrita da história.

Abstract The “dulce de leche”, a viscous milk candy spread, is one of the most produced Brazilian dairy products. However, it is still mostly made from cow’s milk and the sheep’s milk rarely used in its production. This study aimed to obtain and physicochemically characterize the whole milks and the “dulce de leche” (DL) made from cow’s (CM) and sheep’s milk (SM), and CM:SM mixing rations of 100:0, 75:25, 50:50, 25:75 and 0:100. Milk’s physicochemical analyzes were pH, titratable acidity, density, moisture, total solids, proteins, lactose, fats, and ash. DL physicochemical analyzes were the same of the milk plus yield, color, and texture profile analysis. From inclusion of sheep’s milk, the DL presented higher values of total solids, ashes and protein, with lipids increased only from the proportion 50:50. Lactose decreased at the proportion 0:100, however, was similar to the 25:75 proportion. The moisture decreased as the inclusion of sheep’s milk on the product. Regarding color, the difference from the standard sample was verified with the inclusion of higher proportions of sheep milk. The combination of sheep’s milk and cow’s milk is a technically viable alternative, as it considerably increases the nutritional value and yield of the product.
