RESUMO
Milk fats and related dairy products are multi-functional ingredients in bakeries. Bakeries are critical local industries in Western countries, and milk fats represent the most important dietary lipids in countries such as New Zealand. Milk fats perform many roles in bakery products, including dough strengthening, textural softeners, filling fats, coating lipids, laminating fats, and flavor improvers. This review reports how milk fats interact with the ingredients of main bakery products. It also elaborates on recent studies on how to modulate the quality and digestibility of baked goods by designing a new type of fat mimetic, in order to make calorie- and saturated fat-reduced bakery products. It provides a quick reference for both retailers and industrial manufacturers of milk fat-based bakery products.
RESUMO
La actividad panificante valorada como producción de CO2 de dos cepas comerciales de Saccharomyces cerevisiae pudo ser incrementada, principalmente en amasijos azucarados, por la aplicación de un esquema de hambreado/ pulso¼ de melaza de caña de azúcar durante su propagación bajo la forma de lote alimentado. Dicho incremento fue dependiente de la cepa utilizada. Otras características relacionadas con el comportamiento industrial de las levaduras no se vieron afectadas, con excepción de la concentración intracelular de trehalosa.Se discute la aplicabilidad del método para la producción industrial de levaduras de panificación.
Baking activity determined as CO2 production of two commercial strains of Saccharomyces cerevisiae could be increased mainly in sweet bread doughs by introducing a starvation/ pulse feeding schedule of sugar cane molasses during a fed-batch propagation . Such increase was strain dependent. Except for the trehalose intracellular level, other traits related to the yeast industrial performance were unaffected. Applicability of method for bakers yeast industrial production is discussed.
