“…Recent studies on camel milk powder have been focused on its particle structure and surface composition (Zouari, Schuck et al., 2020), as well as its behavior during drying (Habtegebriel, Edward, Wawire, Sila, & Seifu, 2018; Zouari et al., 2019; Zouari, Mtibaa et al., 2020) and its physicochemical changes upon storage (Ho et al., 2019; Zouari, Briard‐Bion et al., 2020). However, none of these explained the practical conditions to use skimmed or whole‐fat camel milk powder in future applications.…”

In this study, three skimmed and one whole‐fat spray‐dried camel milk powders were produced and their characteristics were compared to those of bovine milk powders. The physicochemical analysis of the produced powders indicated that camel milk powders (whether skimmed or not) presented higher ash and whey protein contents as compared to those of bovine milk powders. Our results indicated that the investigated camel and bovine milk powders exhibited a high solubility index (>99%) with poor dispersibility and wettability indexes due to their small particles size (d50 ≤ 12 µm) and their narrow size distribution (span ≤ 2). In addition, although camel and bovine milk powders presented the same total fat content, lower free fat content was measured for camel milk powders. Besides, the whey protein nitrogen index and the SDS‐PAGE electrophoresis underlined that camel and bovine milk proteins remained intact after drying with low denaturation extent. It is worth noticed that camel milk proteins were less denaturized due to the absence of the heat‐sensitive β‐lactoglobulin in camel milk. Moreover, the low denaturation extent participated in the enhancing of the foaming capacity and stability of camel and bovine milk powders. Finally, the calorimetric analysis showed that higher fat melting temperatures were recorded in whole‐fat camel milk powder and in their anhydrous form as compared to those of bovine milk.Practical ApplicationCamel milk powder is an emerging non‐bovine dairy product. Understanding its rehydration ability and evaluating the impact of spray drying on its protein quality are promising approaches to obtain high‐quality camel milk powder with high reconstitution ability. Findings of this study indicated that spray drying is a suitable technique to produce highly soluble camel milk powders with low denaturation extent. These results will benefit the research and development department of food industry (especially those producing camel milk powder) as well as the direct consumers.

“…The MLR and ANOVA were performed on each physical quality attribute as well as the yield. It was suggested that a good regression model should have R 2 no less than 80%, 37 and the p-value of model should be less than 0.05. The fitting results illustrated that the yield, hygroscopicity, and particle size distribution width could not be fitted well (i.e., R 2 The pareto charts of standardized effects on MC (Figure 1A) and SSA (Figure 1B) are shown.…”

Purpose: Understanding raw material variability and its impact on product quality are crucial for developing robust pharmaceutical processes. This work aimed to study the effects of spray drying conditions on properties of the spray dried Panax notoginseng saponin (PNS) powders as well as the subsequent intra-batch dissolution variability of PNS hydrophilic matrix tablets. Methods: The Plackett-Burman design was applied to screen the critical process parameters (CPPs). Then, the Box-Behnken design was used to investigate the relationship between the CPPs and the physiochemical properties of spray dried PNS powders. The PNS hydrophilic matrix tablets containing 57% spray dried PNS powders were directly compressed. The partial least squares (PLS) regression was used to uncover the hidden multivariate relationships among the CPPs, intermediate powder properties, and tablet quality attributes. Results: The identified CPPs were the feed concentration, the inlet air temperature, and the atomization pressure. It was found that the CPPs exerted little impact on chemical properties of spray dried PNS powders, but had significant impact on physical properties, such as particle size, specific surface area, bulk density, hygroscopicity, and inter-particle porosity, etc. Latent variable modeling results revealed that the high inlet air temperature of spray drying process could produce PNS powders with low moisture content and high hygroscopicity, which were beneficial to reduce the intra-batch dissolution variability of PNS hydrophilic matrix tablets. Finally, a design space of the spray drying process was built in order to ensure the dissolution consistency. Conclusion:Our research provided a reference for improving the spray drying conditions in order to ensure the dissolution consistency of the PNS hydrophilic matrix tablet.

“…Heat consumption during a constant drying rate remains constant, and increases during a period of a decreasing drying rate. At the final stage, starting with the mass fraction of moisture in the product, energy consumption increases many times [18][19][20]. This makes the spray drying process ineffective.…”

Introduction. One of the promising methods in the production of dairy and other food in concentrated, condensed and dry forms is a consistent combination of dehydration methods. The subject of this research relevant now is approaches to the calculation of such processes. The work objective is to analyze the dehydration staging effect on the energy consumption in this process. Study objects and methods. Liquid, concentrated and powdered dairy products: whole and skim milk, milk whey, whole milk substitutes, as well as their dehydration parameters at certain stages. The determination of moisture and solids mass fraction in products was carried out with a standard method. Results and discussion. The feasibility of using a multi-stage dehydration method for the production of various types of powder milk products has been justified. The characteristic boundaries of solids mass fraction at different stages of the process were determined. The material-balance equation made it possible to define the formula for the total specific energy consumption relative to the unit of the final dry product at an arbitrary number of dehydration stages. The paper contains examples of a comparative efficiency assessment of the dehydration process carried out at different stages from the point of view of energy costs of its implementation. Conclusion. The research featured various issues related to the use of dehydration methods in the production of milk powder products. An equation has been drawn up to estimate the specific energy consumption of the multi-stage dehydration process relative to a unit of the final dry product. The use of a multi-stage process allows to effectively reduce the specific energy consumption, as well as to generate new high quality products.
