The implementation of automation in dough kneading has revolutionized production by ensuring precision, reproducibility, and scalability. Programmable kneading systems allow for the optimization of critical variables, such as speed, duration, and sequence, which are crucial for proper gluten development. Gluten development directly impacts dough elasticity, gas retention, and overall product quality.

Automated kneading systems also reduce human error, ensuring consistent results across production cycles. In large-scale industrial operations, these technologies enhance process efficiency and reduce manual intervention (Telychkun et al., 2019; Venturi et al., 2022). Moreover, innovative kneading machines now incorporate sensory data analysis for real-time monitoring of dough properties, enabling immediate adjustments to mixing parameters.

Key Developments:

• Smart Mixers: Equipped with adaptive algorithms, smart mixers can adjust to variations in ingredient quality and environmental conditions.
• Industry Integration: Automation systems now connect kneading, fermentation, and baking stages into a unified interface, enhancing overall production efficiency.

2. Temperature Control During Kneading

Precise temperature regulation during kneading is essential to maintaining yeast activity and facilitating optimal gluten structure development. Overheating during kneading can lead to premature fermentation and enzymatic degradation, adversely affecting dough properties. Innovations such as self-cooling mixers with integrated refrigeration systems ensure that dough remains within the ideal temperature range of 23–27°C, preventing these issues (Cappelli et al., 2020).

Conversely, excessively low temperatures slow gluten hydration and fermentation, necessitating adjustments in processing times. Advanced thermal sensors integrated into modern kneading equipment enable real-time temperature monitoring and control, ensuring consistent product quality.

3. Non-Destructive Quality Monitoring

Recent advances in non-destructive monitoring technologies, such as near-infrared (NIR) spectroscopy and hyperspectral imaging (HSI), have become pivotal for real-time assessment of dough quality. These techniques analyze dough properties—such as moisture content, gluten development, and gas cell formation—without the need for sample destruction.

Applications:

1. Moisture and Fermentation Monitoring: NIR spectroscopy effectively tracks dough hydration and fermentation progress, optimizing ingredient usage and minimizing waste (Guerrini et al., 2021).
2. Microstructural Analysis: HSI provides spatially resolved data on gas distribution and gluten alignment, which are critical for achieving consistent crumb texture and uniform structure.
3. Staling Prediction: NIR and HSI help predict starch retrogradation and protein matrix degradation, enabling adjustments to formulations for extended product shelf life.

4. Indicators of Well-Leavened Dough

Well-leavened dough is characterized by its capacity for expansion, gas retention, and the formation of a stable gluten network. Key indicators of high-quality leavening include:

1. Gas Production and Retention: Efficient trapping of carbon dioxide within the gluten network is directly correlated with dough volume and crumb structure (Wang et al., 2020).
2. Dough Volume and Expansion: Digital imaging studies have demonstrated the influence of fermentation time and temperature on dough volume, with uniform expansion indicating balanced yeast activity and gluten elasticity (Zhang et al., 2019).
3. Rheological Properties: The balance between elasticity and viscosity is critical for maintaining dough stability. Oscillatory rheological testing reveals that well-leavened dough exhibits superior viscoelastic properties (Chen et al., 2021).
4. Microstructural Characteristics: Scanning electron microscopy (SEM) has shown that properly leavened dough features a continuous gluten network with evenly distributed gas cells (Li et al., 2018).

5. Effects of Flour Quality on Dough Properties

The quality of flour is a pivotal determinant of dough performance and baked product attributes. High-quality flour is characterized by an abundance of gluten-forming proteins, gliadin and glutenin, which contribute to elasticity, gas retention, and structural stability during baking.

High-Quality Flour:

• Protein Content and Gluten Development: Elevated protein levels enhance gluten elasticity and gas-trapping efficiency, resulting in superior bread volume and crumb texture (Ma et al., 2024).
• Water Absorption: High-quality flours demonstrate consistent hydration properties, ensuring uniform dough mixing and kneading (Sun et al., 2024).

Low-Quality Flour:

• Structural Weakness: Flours with low protein content or damaged starches produce weaker gluten networks, leading to poor gas retention and denser products (Ma et al., 2024).
• Texture Inconsistencies: Poor-quality flour often results in uneven hydration, negatively affecting crumb softness and elasticity.

6. The Role of Water Quality

Water plays a critical role in dough preparation, influencing its hydration, fermentation, and rheological behavior.

Key Factors:

1. Mineral Content: Hard water, rich in calcium and magnesium ions, strengthens gluten networks, while soft water can weaken dough structure (Sehn et al., 2015).
2. pH Levels: Slightly acidic water enhances yeast activity and fermentation efficiency, whereas alkaline water impairs these processes (Johnson & Lee, 2023).
3. Purity: Excessive chlorine or impurities in water can negatively affect fermentation and dough flavor (Lau, Jain & Perron, 2024)

7. Advances in Fermentation Technologies

Innovations in fermentation technologies, particularly the use of wild yeasts (e.g., Saccharomyces cerevisiae) and lactic acid bacteria (LAB), have transformed dough flavor and shelf-life management. Extended fermentation processes foster the development of complex aromatic compounds, improving sensory qualities while reducing reliance on chemical preservatives (Das et al., 2023).

8. Bread Staling and Mold Growth

Bread stalling and mold proliferation are closely linked to dough structure and ingredient distribution.

• Staling Prevention: Proper kneading develops a robust gluten network, delaying moisture migration and starch retrogradation, thereby extending shelf life (Sehn et al.,2015).
• Mold Resistance: Uniform crumb structure minimizes niches for microbial growth, while adequate salt and preservative integration further inhibits mold development (Lee et al., 2021).

9. Health and Nutritional Trends

Consumer demand for healthier baked goods has led to increased interest in whole-grain, gluten-free, and high-fiber formulations. Advances in hydrocolloid and enzyme technologies have enabled the production of functional baked goods that balance nutrition and sensory appeal (Codină & Dabija, 2025).
