The effect of rice flour addition on pasta quality: a case study from the republic of uzbekistan

Аннотация

The study investigates the impact of rice flour addition to wheat flour in pasta production, focusing on quality attributes such as texture, cooking properties, and sensory evaluation. The research explores the physicochemical changes occurring due to different rice flour concentrations (10%, 20%, and 30%) and their effect on gluten structure, firmness, and cooking stability. Laboratory analyses, including protein content, moisture retention, and elasticity tests, were conducted to evaluate the influence of rice flour substitution. The results indicate that a moderate incorporation of rice flour (10–20%) maintains acceptable pasta quality while improving digestibility and reducing gluten-related concerns. However, excessive rice flour content (30%) negatively impacts structural integrity and sensory appeal. This study provides valuable insights into alternative flour utilization in pasta production, contributing to the development of gluten-modified and functional food products.

Introduction: Pasta is one of the most widely Additionally, it enhances the digestibility and consumed staple foods globally, known for its nutritional composition of pasta while altering its versatility, affordability, and nutritional value. texture and cooking characteristics. However, due to Traditionally, pasta is produced from durum wheat the absence of gluten, rice flour incorporation may lead semolina, which provides the necessary gluten network to reduced elasticity, increased cooking loss, and to maintain its structural integrity, texture, and cooking changes in sensory attributes. Understanding the stability. However, with the increasing demand for optimal level of rice flour addition that maintains pasta gluten-free and functional food alternatives, quality while offering dietary benefits is crucial for food researchers have explored the incorporation of non- scientists and manufacturers. wheat flours, such as rice flour, to modify the physicochemical properties of pasta. This study aims to evaluate the effect of rice flour incorporation on pasta quality by analyzing key Rice flour, being gluten-free, offers potential benefits American Journal of Applied Science and Technology 25 https://theusajournals.com/index.php/ajast American Journal of Applied Science and Technology (ISSN: 2771-2745) parameters such as protein content, moisture 12 hours to achieve a final moisture content of retention, firmness, cooking loss, and sensory approximately 12%. perception.
