“…T and M carriers together may therefore have synergistic effect in inhibiting aggregation during spray–drying. This effect has also been reported for trehalose and another CD, hydroxypropyl–β–CD and for trehalose and bovine serum albumin (BSA) in the stabilization of monoclonal antibodies and xanthine oxidase, respectively [ 55 , 56 ].…”

This effect has also been reported for trehalose and another CD, hydroxypropyl-β-CD and for trehalose and bovine serum albumin (BSA) in the stabilization of monoclonal antibodies and xanthine oxidase, respectively [55,56]. The sericin that was dried without T and M carriers (sd_S) gave a powder that was made up of particles whose diameter was smaller than that obtained using the carrier agents (sd_SMT), as assessed by the PSD studies (see below).…”

“…The combination of T and M carriers improved the process yield compared to the spray-dried carrier alone (sd_MT: 49.6 ± 1.9% w/w vs sd_M: 23.6 ± 5.3% w/w and sd_T: 36.9 ± 2.7% w/w). The spray-drying of the sericin dispersion containing T and M gave a process yield that was even higher (sd_SMT: 58.9 ± 1.2% w/w), at more than 50% w/w, which is the landmark value beyond which the process can be defined as successfully performed [56]. This satisfying yield, which is noticeably The sd_S and sd_SMT powders were made up of microparticles characterized by rough surfaces, with hollows and wrinkles due to the partial collapse of the particles [53].…”

Effect of Methyl–β–Cyclodextrin and Trehalose on the Freeze–Drying and Spray–Drying of Sericin for Cosmetic Purposes

Sericin is a protein extracted from Bombyx mori silk cocoons. Over the last decade, this wastewater product of the textile industry has shown many interesting biological properties. This protein is widely used in the cosmetic and biomedical fields. In this study, sericin has been obtained via a High–Temperature High–Pressure degumming process, and was dried using the freeze–drying (fd) and spray–drying (sd) techniques. Proteins tend to collapse during drying, hence, sericin has been dried in the presence of two selected carrier agents: methyl–β–cyclodextrin and trehalose. The obtained powders have been analyzed using thermal investigation, microscopy (optical, SEM), and granulometric and spectroscopic analyses. Moreover, the percentage yield of the spray–drying process has been calculated. Both the agents were able to significantly improve the drying process, without altering the physico–chemical properties of the protein. In particular, the co–spray–drying of sericin with methyl–β–cyclodextrin and trehalose gave good process yields and furnished a powder with low moisture content and handling properties that are better than those of the other studied dried products. These characteristics seem to be appropriate and fruitful for the manufacturing of cosmetic raw materials.

“…Conditions that result in sufficient drying of the particles enhance the product yield. In our study, all spray drying conditions exceeded the satisfactory level of 50% for a laboratory scale spray dryer [13], with results ranging from 81.3% to 93.4%. We observed significant differences among treatments.…”

Phenolic compounds obtained from blueberries have gained great attention due to their more effective bioactive roles in human health than those of whole berries. However, they are sensitive to environmental conditions and are therefore susceptible to degradation affecting their effectiveness. The microencapsulation of these compounds by spray drying provides a solution to these problems. This work aimed to study the effect of spray drying on the microencapsulation of the blueberry phenolic compounds to optimize the production of a powder rich in stable polyphenols. The phenolic extract from blueberries was spray dried under different conditions of inlet air temperatures (140 and 160 °C) and encapsulating agent concentrations (20 and 30% w/v), using maltodextrin (14.7 dextrose equivalent). The drying yield, moisture content, water-solubility, total and surface phenolic content, and encapsulation efficiency of total phenolic were investigated. The results obtained showed that the different conditions evaluated influenced the drying yield, moisture content, surface phenolic content, and encapsulation efficiency of phenolic compounds. In this sense, the powders with the best characteristics were obtained with 30% w/v of maltodextrin at 160 °C inlet temperature. These powders, rich in blueberry polyphenols stabilized by microencapsulation, are easier to handle for application, so they could be used as functional food ingredients.

“…At this optimized condition, bacterial survival and residual moisture were satisfactory, and powders were easy to be dispersed and solubilized. Yet, the drying yield obtained for this condition was almost 74%, exceeding the satisfactory level of 50% in a laboratory scale spray dryer (Selvamuthukumaran 2019).…”

Aims To investigate the influence of different culture media and fermentation conditions on growth performance and viability of three lactic acid bacteria (LAB) strains with potential as silage inoculants, and to optimize spray‐drying in order to enhance survival to dehydration and storage stability. Methods and Results In house‐formulated MRS was a suitable low‐cost culture medium for Lactobacillus plantarum Hv75, Pediococcus acidilactici 3903 and L. buchneri B463. Uncontrolled pH biomass production conferred enhanced stability during storage at 4°C after spray‐drying. The use of whey protein concentrate 35 (WPC)‐maltodextrin (M) as matrix, inlet temperature of 145‐150°C and air flow rate of 601 l h−1 was adequate for the production of dehydrated LAB. According to the desirability function, at this optimized condition, moisture content, yield and solubility were predicted to be 3·96, 73·68 and 90·36% respectively. Those conditions also showed a decrease of 0·855 log CFU per gram after drying, no loss in viability at 4°C for 6 months and 1 log CFU per gram reduction at 25°C. Conclusions Stable and economically feasible dehydrated LAB cultures were obtained using alternative culture media, fermentation under uncontrolled pH and optimizing spray‐drying process conditions through the desirability function method. Significance and Impact of the Study Our results can be utilized for efficient production and commercialization of several dry LAB.
