Assessing the Technological and Nutritional Functionality of Curd Cheese in the Overall Gluten-Free Bread Quality| Chapter 5 | Emerging Challenges in Agriculture and Food Science Vol. 5

The absence of gluten has a substantial impact on overall bread quality, thus replacing wheat flour in the breadmaking process is a technological challenge. Protein-rich source replacements are frequently utilised to assist in the creation of a protein network capable of replicating gluten-like structure in order to support the dough foaming gas cells. Aside from protein structure, the association with starch granules may be advantageous in making them less susceptible to enzymatic breakdown, thereby providing a nutritional benefit. When proteins and lipids are included in the bread matrix, the nutritional benefits are amplified because the lipids can create lipid-amylose complexes that affect the final dough consistency. As a result, nutritional improvements in terms of gluten-free bread's glycemic response might be favourable. improved.


The goal of this study was to assess curd cheese's technological and nutritional functioning as a protein and fat source, as well as a prospective alternative bakery component in gluten-free breadmaking. The impact of curd cheese, based on its ability to strengthen gluten-free dough structure, was evaluated in detail by testing several levels of addition (5 percent to 20%, weight/weight) that focused on: I dough rheology properties, primarily flow and viscoelastic profile modifications, and ii) starch physical behaviour by pasting properties measurements. The post-baking quality of the resulting bread samples was measured to assess their quality. Nutritional gains were evaluated in terms of chemical composition and glycemic response. When the greatest level of curd cheese (20%) was evaluated, improvements in bread quality were noted, with a significant increase in bread volume (73%) and softness (65%) and a significant reduction in staling kinetic (70%) when compared to control bread. Furthermore, there was an increase in nutritional value in terms of proteins (80%) and minerals content, notably P, Mg, and Ca, covering more than 15% of daily required dosages. In terms of glycemic reaction, a significant decrease of 40% was obtained, resulting in bread with an intermediate glycemic index. Dough rheology parameters were shown to have strong linear associations (R2 > 0.902) with bread quality features, pasting properties, in vitro starch digestibility, and glycemic index. The linear relationships discovered may be utilised to support the notion that adding curd cheese to the bread had a significant impact on its overall quality and nutritional content.
