Special Issue Information

Dear Colleagues,

This Special Issue aims to present the latest research on the influence of various pre-treatments and drying techniques on the properties of dried fruits and vegetables, especially their pro-healthy and sensory qualities.

Experts point to the diet's low consumption of fruit and vegetables as a source of fiber, vitamins, minerals, and other essential bio-components. Various snacks are gaining more and more popularity. Consumers eat snacks because they satisfy hunger quickly and do not require preparation. Many consumers are looking for products that meet their health expectations. They choose products with a “clean label”, but which exhibit appropriate sensory qualities. They are also aware of saving energy resources on a global scale.

In response to consumer expectations and global needs, the research scope of this Special Issue includes the latest solutions using pre- or post-treatment and improved drying methods, including hybrid methods, enabling the production of high-quality dried fruit and vegetable snacks towards the development of sustainable technologies. As part of the development of their production technology, thermal and non-thermal treatments are being studied which affect changes in the structure of plant tissue in the direction of increasing drying efficiency and reducing energy demand.

Osmotic enrichment as pre-treatment or final roasting with spices increases the content of desired ingredients and shapes the attractiveness of products from a health-promoting and sensory perspective.

The development of gluten-free biscuits with high nutritional value presents a challenge for the food industry. This study evaluated the dough behavior and quality characteristics of gluten-free biscuits obtained using the raw materials sorghum flour, sesame paste, and Moringa oleifera leaf powder. Ten formulations were developed, including a control sample without moringa, using a mixture design that generated different combinations between sorghum flour, sesame paste, and powdered moringa. Moringa-enriched biscuits showed significant nutritional improvements, with protein increasing by 40% (12.07–16.93%), fiber by 92% (2.78–5.34%), polyphenols more than twofold (52.88–120.66 mg GAE/100 g), and flavonoids more than threefold (110.44–335.30 mg QE/100 20 g). Technological properties such as rheology, texture, color, and water activity varied with formulation. Moringa addition darkened biscuits (L* 35.61–49.74) and increased hardness by 62% (20.53–33.19 N). All doughs exhibited dominant viscoelastic behavior (G′ > G″), with higher sorghum levels leading to increased viscoelasticity. FTIR analysis confirmed characteristic functional groups of carbohydrates, lipids, and proteins across samples. Sensory evaluation indicated good overall acceptance, with a preference for the control sample and the sorghum-rich formulation (F4), which contained the lowest amounts of sesame paste and powdered moringa. Overall, Moringa oleifera enhances both nutritional and technological properties of gluten-free biscuits; therefore, it can contribute to the development of functional products from local resources.

White radish is a nutritious root vegetable that provides dietary fiber, essential vitamins and minerals, and a range of bioactive compounds. This study aimed to determine how steam and microwave blanching, pulsed electric field, ultrasound, osmotic dehydration with inulin or trehalose, and coating with spices such as turmeric or sweet paprika influence the characteristics of convective infrared dried white radish slices. To assess the effect of each pretreatment, moisture content, water activity, shrinkage, density, texture, color parameters, structural characteristics (SEM and µ-CT), vapor adsorption, thermal changes, and antioxidant properties were analyzed. Osmotic dehydration with inulin most effectively limited shrinkage and color change, stabilized the microstructure, and resulted in the highest relative phenolic content and antioxidant activity (TPC, DPPH). Spice-coated samples showed low shrinkage, low hardness and breaking work, and vivid color. Furthermore, µ-CT microstructure analysis showed that these samples had the highest porosity, with those with paprika reaching 57.5%. In contrast, blanching, ultrasound, and PEF led to greater structural changes and increased hygroscopicity. Multivariate analyses confirmed the significant influence of the type of pre-treatment on the quality characteristics of the dried material. Osmotic dehydration and spice coating proved to be the most effective methods for obtaining structurally stable and visually attractive dried white radish slices with attractive bioactive compounds.

Pseudocereals are naturally gluten-free crops because they do not contain gluten-forming proteins which are present in other grains. The main pseudocereals used in bakery formulations are buckwheat, amaranth, and quinoa, because they have a balanced nutritional profile including high-quality proteins, dietary fiber, essential minerals, and bioactive compounds with antioxidant, anti-inflammatory, and cardiometabolic health-promoting effects. Due to their high nutritional value, they have increasingly been used as functional ingredients in bakery products, particularly for consumers with celiac disease, gluten intolerance, or those seeking nutritionally enhanced foods. The present paper reviews recent advances on the nutritional, functional, and technological properties of these pseudocereals, focusing on their applications in bakery products. Their influence on dough behavior, product quality, and the nutritional improvement of bread, cakes, biscuits, muffins, and other baked goods is discussed. Also, different aspects of the use of pseudocereals in gluten-free products are presented. Mentions are also made of the fact that the increasing demand for healthier and gluten-free foods highlights the possibility of using pseudocereals as promising ingredients for the development of nutritionally enriched bakery products of acceptable technological and sensory quality.
