“…The study by Rostamabadi et al [31] showed that using gum arabic as an adhesive resulted in higher germination percentages compared to other adhesives like CMC and Chitosan in tomato and cucumber seed coating treatments. Similarly, Al-Hamayda et al [32] reported that using 3% gum arabic + 1% talc increased the germination percentage to 87%, higher than the control group, which only reached 80%. However, in this study, using gum arabic as an adhesive did not increase the germination percentage of soybean seeds.…”

This study evaluates the effectiveness of Actinomycetes in encapsulating soybean seeds to control damping-off disease caused by Sclerotium rolfsii. With national soybean demand reaching 22 million tons per year and domestic production only 1 million tons, increasing production is essential. One major constraint is the attack of plant pathogens such as S. rolfsii, which can cause significant losses. Actinomycetes were isolated from the rhizosphere of weeds and tested for their antagonistic activity in vitro. Seed encapsulation using various carriers (kaolin, talc, and zeolite) was conducted to determine the most effective formula. In vivo tests showed that the Actinomycetes isolate PM2 exhibited the best antagonistic activity, with the zeolite formulation reducing pre-emergence damping-off disease incidence to 12.50% and post-emergence damping-off to 8.25%, compared to the positive control. These results indicate that the use of Actinomycetes in soybean seed encapsulation is an effective and sustainable method for controlling damping-off disease. Zeolite as a carrier proved to provide a supportive environment for antagonistic microbes, maintaining moisture and supplying necessary nutrients. This research reveals the great potential of Actinomycetes as a biocontrol agent in plant disease management strategies, which can significantly enhance soybean production and support national food security.

“…These characteristics limit their use in industrial applications [19]. Encapsulation of EOs can overcome these barriers by decreasing the interactions between the "core" (i.e., encapsulated ingredient) and the environment [2,18,[20][21][22]. It is an effective technique to decrease their volatility and sensitivity to environmental conditions, to enable their controlled release [2,23], decrease their degradation [1], mask their strong organoleptic characteristics [18], and enhance their antimicrobial activity [3,15,24].…”

“…Consequently, the lyophilization process, which is slower and entails higher energy consumption, is more suitable for delicate applications [28,29]. During lyophilization, low temperatures (below the freezing point of water) and a very low pressure (high vacuum) are maintained to enable the sublimation of water (ice) [22]. The lyophilization process is composed of mainly four stages: (1) freezing, (2) ice sublimation (primary drying), (3) desorption of unfrozen water (secondary drying), and (4) storage [26,[30][31][32].…”

Efforts to tap into the broad antimicrobial, insecticidal, and antioxidant activities of essential oils (EOs) are limited due to their strong odor and susceptibility to light and oxidation. Encapsulation of EOs and subsequent drying overcome these limitations and extend their applications. This study characterized freeze-dried (lyophilized) emulsions of eugenol (EU) and thymol (TY) EOs, encapsulated by chemically unmodified cellulose, a sustainable and low-cost resource. High-resolution scanning electron microscopy showed successful lyophilization. While the observed “flake-like” structure of the powders differed significantly from that of the emulsified microcapsules, useful properties were retained. Fourier transform infrared spectroscopy confirmed the presence of EOs in their corresponding powders and thermo-gravimetric analysis demonstrated high encapsulation efficiency (87–88%), improved thermal stability and resistance to evaporation, and slow EO release rates in comparison to their free forms. The lightweight and low-cost cellulose encapsulation, together with the results showing retained properties of the dried powder, enable the use of EOs in applications requiring high temperatures, such as EO incorporation into polymer films, that can be used to protect agricultural crops from microbial infections.

This study aimed to assess the technical feasibility of incorporating selenized Lactobacillus spp. microencapsulated via spray drying into cattle feed. Gum Arabic and maltodextrin were used as encapsulating agents. The encapsulation process was carried out with a drying air flow rate of 1.75 m3/min, inlet air temperature of 90°C, and outlet air temperature of 75°C. The viability of the encapsulated microorganisms and the technological characteristics of the obtained microparticles were evaluated. Microorganisms were incorporated into beef cattle feed to supplement their diet with up to 0.3 mg of Se per kilogram of feed. The encapsulated particles, consisting of a 50/50 ratio of gum Arabic/maltodextrin at a 1:20 proportion of selenized biomass to encapsulant mixture, exhibited superior technical viability for application in beef cattle feed. Supplemented feeds displayed suitable moisture, water activity, and hygroscopicity values, ensuring the preservation of viable microorganisms for up to 5 months of storage, with an approximate count of 4.5 log CFU/g. Therefore, supplementing beef cattle feed with selenized and microencapsulated lactic acid bacteria represents a viable technological alternative, contributing to increased animal protein productivity through proper nutrition.
