Bioengineered xylanase from Misiones Argentina rainforest: A bakery enhancement approach.

In this study, we pursued the heterologous expression of the xylanase gene from Trichoderma atroviride, a native fungus in the province of Misiones, and used it to enhance the textural properties of baked goods through varying enzymatic concentrations. This marks the inaugural exploration into its functionality in the context of bread production. The recombinant xylanase exhibited improved activity, reaching 36,292 U L, achieved by supplementing the culture medium with dextrose.

Effect of the incorporation of pregelatinized cassava starch on the physicochemical, textural, and acoustic characteristics of baked snacks.

Almost all the dehydrated cassava puree is pregelatinized cassava starch (PCS). Its potential application in food would add variety. But food characteristics vary depending on the raw materials used.

Purification and characterization of a fungal laccase expressed in Kluyveromyces lactis suitable for baking.

Laccase enzyme can replace chemical additives to improve texture properties and the volume of bread. Laccase encoding gene from Phlebia brevispora, a native fungus from Misiones, Argentina, was expressed in the generally recognized as safe yeast Kluyveromyces lactis. To improve laccase activity, medium conditions were optimized.

Variation of color with baking time in snacks made with pregelatinized cassava.

Color is an importantaspect when formulating products, as the consumer will evaluate this aspect in the first instance. There is a growing interest in non-wheat producing regions to replace it with local sources of starches. However, the substitution of wheat flour affects characteristics such as texture, flavor, and color of the intermediate and final products.
