Comparison of Electrostatic Spray Drying, Spray Drying, and Freeze Drying for Lacticaseibacillus rhamnosus GG Dehydration. Foods 2023; 12:3117. [PMID: 37628116 PMCID: PMC10453923 DOI: 10.3390/foods12163117] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Revised: 08/14/2023] [Accepted: 08/17/2023] [Indexed: 08/27/2023] Open
Abstract
Spray drying (SD) is extensively used to encapsulate lactic acid bacteria in large-scale industrial applications; however, bacteria combat several harms that reduce their viability. In this study, a novel technique called electrostatic spray drying (ESD) was used to explore the benefits and disadvantages of using electrostatic charge and lower temperatures in the system. Freeze drying (FD) was used as a reference. The effect of different encapsulation agents, like maltodextrin, arabic gum, and skim milk, on the viability of Lacticaseibacillus rhamnosus GG (LGG) was investigated. The initial cell concentration, particle size distribution, aspect ratio, sphericity, scanning-electron-microscopy images, moisture content, water activity, glass transition, rehydration abilities, and survival during storage were compared. Skim milk was proven to be the best protectant for LGG, regardless of the drying process or storage time. A huge reduction in cell numbers (4.49 ± 0.06 log CFU/g) was observed with maltodextrin using SD; meanwhile, it was protected with minimum loss (8.64 ± 0.62 log CFU/g) with ESD. In general, ESD preserved more LGG cells during processing compared to SD, and provided better stability than FD and SD during storage, regardless of the applied voltage. The ESD product analysis demonstrated an efficient LGG preservation, close to FD; therefore, ESD presented to be a promising and scalable substitute for SD and FD.

Crit Rev Food Sci Nutr 2020; 62:2470-2494.

Abstract
Oral administration of live probiotics along with prebiotics has been suggested with numerous beneficial effects for several conditions including certain infectious disorders, diarrheal illnesses, some inflammatory bowel diseases, and most recently, irritable bowel syndrome. Though, delivery of such viable bacteria to the host intestine is a major challenge, due to the poor survival of the ingested probiotic bacteria during the gastric transit, especially within the stomach where the pH is highly acidic. Although microencapsulation has been known as a promising approach for improving the viability of probiotics in the human digestive tract, the success rate is not satisfactory. For this reason, co-encapsulation of probiotics with probiotics has been practised as a novel alternative approach for further improvement of the oral delivery of viable probiotics toward their targeted release in the host intestine. This paper discusses the co-encapsulation technologies used for delivery of probiotics toward better stability and viability, as well the incorporation of co-encapsulated probiotics and prebiotics in functional/synbiotic dairy foods. The common encapsulation technologies (and the materials) used for this purpose, the stability and survival of co-encapsulated probiotics in the food, and the release behavior of the co-encapsulated probiotics in the gastrointestinal tract have also been explained. Most studies reported a significant improvement particularly in the viability of bacteria associated with the presence of prebiotics. Nevertheless, the previous research has mostly been carried out in the simulated digestion, meaning that future systematic research is to be carried out to investigate the efficacy of the co-encapsulation on the survival of the bacteria in the gut in vivo.

Abstract
Awareness about probiotic food and their health benefits is increasing tremendously. However, probiotics have to withstand the harsh conditions that come across during their processing, handling, storage, and gastrointestinal conditions. Encapsulating technologies can be used to protect the probiotics during their passage through the gastrointestinal system of the human gut. Probiotics as an ingredient in dry powder form can be easily handled, stored, and used in developing the probiotic functional products. In the present study, probiotic cells (Lactobacillus acidophilus) were encapsulated by spray drying technology to produce a probiotic powder using 20% of maltodextrin and varied concentrations of gum arabic. The effect of processing conditions such as inlet air temperature (130-150 °C) and gum arabic concentration (0-10%) on the encapsulation efficiency and physical properties were studied. Further, the free and encapsulated probiotic cells were exposed to the simulated-gastric intestinal (SGI) fluid conditions and different storage conditions for their viability. For all the tested formula, moisture content, water activity, encapsulation efficiency, hygroscopicity, and wettability obtained were in the range of 4.59-9.05% (w.b.), 0.33-0.52, 65-89.15%, 12-21.15 g H2O/100g dry weight, and 116 s-353 s, respectively. The Fourier transform infrared (FTIR) results have shown that gum arabic and maltodextrin have structural stability during spray drying. The encapsulated probiotic cells have shown a positive effect and exhibited better viability after exposure to a SGI solution at different pH levels and duration compared to free cells. The viability of encapsulated cells stored at refrigerated condition (4 °C) was found to be higher than the viability of cells stored at room temperature (25 °C).

The effects of processing conditions such as inlet air temperature (130-150 °C) and gum arabic concentration (0-10%) on the encapsulation efficiency, physical properties, and morphology were studied. For all the tested formulae, the moisture content, water activity, encapsulation efficiency, hygroscopicity, and wettability obtained were in the range of 4.59-9.05% (w.b.), 0.33-0.52, 65-89.15%, 12 to 21.15 g H2O per 100 g dry weight, and 116 s to 353 s, respectively. The Fourier transform infrared (FTIR) results have shown that gum arabic and maltodextrin show structural stability during spray drying. The encapsulated probiotic cells exhibited better viability of 4.03, 4.68, and 5.34 log CFU g-1 after 3 h of exposure to a simulated gastric fluid (SGF) solution at pH levels of 1, 1.5, and 2, respectively, compared to free cells. The viability of encapsulated cells stored for 12 weeks under refrigerated conditions (4 °C) and at room temperature (25 °C) was found to be 6.05 log CFU g-1 and 1.24 log CFU g-1, respectively.

Abstract
The market of functional foods has experienced a huge growth in the last decades due to the increased consumers’ awareness in a healthy lifestyle. Dried fruits constitute good snacks, in alternative to salty or sweet ones, and food ingredients due to their taste and nutritional/health benefits. Bioactive molecules are interesting sources to develop functional foods, as they play a major role in improving the health status and minimizing disease risks. The bioactive compounds most widely discussed in literature are presented in this review, for example, polyphenols, phytosterols, and prebiotics. Different technologies to dry bioproducts for producing functional foods or ingredients are presented. New drying techniques for the preservation of bioactive compounds are proposed, focusing more specifically on dielectric drying. A discussion on the techniques that can be used to optimize drying processes is performed. An overview on dehydrated plant based foods with probiotics is provided. The microorganisms used, impregnation procedures, drying methods, and evaluated parameters are presented and discussed. The principal bioactive compounds responsible for nutritional and health benefits of plant derived dried food products—fruits and vegetables, fruits and vegetables by-products, grains, nuts, and algae—are presented. Phytochemical losses occurring during pretreatments and/or drying processes are also discussed.
