“…Freeze‐drying is a process for removing ice from a material through sublimation and desorption of bound water molecules. This technique is used to prepare ingredients or other additives for food and feed productions (de Verga & Böhm, ; Kubitza & Lovshin, ; Moayyedi et al, ). It causes less damage to substances that are sensitive to heat, such as enzymes, than other processes that incorporate heat treatment with drying (de Verga & Böhm, ; Fellows, ).…”

Live diets are preferably used for rearing Siamese fighting fish (Betta splendens Regan, 1910) since they provide superior growth over the dry feed. In the current study, three different preparations of mosquito larvae were prepared (frozen at −20°C, F-20; freeze-dried and kept at 4°C, FD4; freeze-dried and kept at ambient temperature, FDAT) and were individually fed to 1-month-old red male fighting fish (1.18 ± 0.01 g initial body weight) over 6 weeks duration. At the end of experiment, there were no significant differences in growth performance and feed utilization across three dietary treatments (p ˃ 0.05). Specific activity of lipase was significantly lower in fish fed FD4 and FDAT than with the F-20 diet, while no differences in other enzymes were observed. The fish fed with FDAT diet significantly increased in viscerosomatic index relative to F-20 and FD4 treatments. Significant improvements in skin redness and flesh quality (RNA and RNA/protein ratio) were observed in the fish fed with FDAT diet relative to the other treatments. This preferred FDAT treatment also maintained the carcass composition. Analysis of digestive enzymes in FDAT mosquito larvae demonstrated the presence of protein-, carbohydrate-, and lipid-digesting enzymes after 1 month of storage. The findings from our experiments indicate that the freeze-dried form (FDAT) of mosquito larvae is suitable for rearing Siamese fighting fish. However, effective preparation protocol and appropriate storage times should be further studied. K E Y W O R D S colour, digestive enzyme, flesh quality, freeze, freeze-dry, live diet

“…Spray drying is the most commonly used encapsulation method in the food industry since it is cost effective, fast, large scale production and highly flexible. 40 However, spray drying has some limitations related to use for heat sensitive materials and it requires precise adjustment of hot gas temperature used. 41 On the other hand, freeze-drying is especially useful for heat labile guests, the low temperature minimises the loss of extremely volatile guests.…”

Caracterização do Complexo de Inclusão do Óleo Essencial de Croton zehntneri e β-Ciclodextrina Preparados Através da Secagem por Atomização e Liofilização Resumo: Croton zehntneri (CZ) é uma espécie aromática da família Euphorbiaceae, nativa do Nordeste do Brasil, rica em óleo essencial (CZEO) com propriedades antioxidante, vasorelaxante, bactericida e fungicida. Apesar dos inúmeros potenciais biológicos e farmacológicos, óleos essenciais são instáveis e possuem limitada solubilidade em água, características que podem ser melhoradas pela formação de complexos de inclusão com ciclodextrinas (CDs). No presente estudo, o complexo de inclusão de CZEO e β-CD foi preparado por co-precipitação acoplada à liofilização e secagem por atomização. O complexo de inclusão foi caracterizado por espectroscopia vibracional (espectroscopia Raman e FT-IR) e a eficiência de complexação determinada por cromatografia gasosa acoplada à espectrometria de massa (CG-EM). Foi observado que a co-precipitação acoplada à liofilização possibilitou uma maior eficiência de complexação quando comparada ao spray drying. A espectroscopia Raman confirma a formação do complexo de inclusão entre CZEO e β-CD por ambos os métodos de preparação.

“…This may be caused because the high vacuum used. The high vacuum gradient can affect the water transfer rate within the molecular structure, resulting in a lower residual aw in the final product [15]. In the SD method, increasing the temperature of the inlet air, increases the temperature gradient between the air flow and the emulsion, which results in the increase of heat transfer and, therefore, the rate of evaporated water [16].…”

Nanoencapsulation is an efficient process to incorporate high nutritional oils, such as high oleic palm oil (HOPO). Several drying technologies can be applied for obtaining HOPO powders. The aim of this work was to study the effect of two different drying methods (spray-drying, SP and freeze-drying, FD) on some physical properties and microstructure of powders obtained from HOPO nanoemulsions. Results showed that FD powders presented lower aw and bulk density, and higher dissolution rate than SD powders. Results suggest that SD could be a more economical alternative to FD in order to obtain HOPO powders with low moisture and aw.
