Abstract:
... The effects of pilot scale freeze- and spray-drying on some functional properties of lactoferrin were studied. Denaturation and loss of function relative to the fresh concentrate as received from a dairy factory was estimated in three ways: (a) from the enthalpy of the denaturation peak; (b) by iron binding capacity as measured by atomic absorption spectroscopy before and after incubation with an ...

Abstract:
... Glucosinolates (GLS) are bioactive compounds found in Brassicaceae vegetables. Industrial food processing treatments, such as blanching, quick-freezing (QF), vacuum freeze-drying (VFD), vacuum-drying (VD) and oven-drying (OD), significantly affect the degradation and ingestion of GLS. Here, the effects of these treatments, followed by boiling, on the GLS content and mimicking ingestion level of is ...

Abstract:
... The added value of Lactobacillus acidophilus encapsulation due to its production process is one of the first things that need to be known in calculating techno-economic analysis to determine the sustainability of its downstream. The result of value-added analysis plays an important role in determining which formulation, encapsulate material, and production process should be used. The inoculum medi ...

Abstract:
... Primary and secondary cracks often coexist in a dried colloidal deposit. While, primary cracks have been the focus of investigation in most of the theoretical and experimental studies, understanding the formation and time evolution of secondary cracks is scarce. In addition, secondary cracks at times are undesirable especially when used as a template in the nano-lithography. Therefore, a control o ...

Abstract:
... Oyster protein hydrolysate (OPH) has high bioactivity and excellent performance, but its application in food formulation is still limited due to poor flavor and instability. In the present study, OPH was prepared by enzymatic hydrolysis and loaded into nanoliposomes. Then, the effects of chitosan coating (0, 0.25, 0.5, and 1.0%) on the physical properties, stability, and antioxidant activity were ...
... This study aimed to produce protein hydrolysates from sesame bran using ultrasound-assisted enzymatic extraction followed by spray-drying (SD) and freeze-drying (FD) techniques. Spray drying parameters highly influenced powder yield (22.8–70.5%), protein yield (23.0–70.4%), drying time (41–149 min) and aw value (0.196–0.288). Therefore, the impacts of SD and FD were assessed after an optimization ...

Abstract:
... When an aqueous colloidal drop dries on a solid substrate, the final pattern of the dried deposit can be manipulated through controlling the internal flow states of the drop.We report a strategy to control the dried patterns of aqueous colloidal drop by controlling the drop configurations and relative humidity. For this purpose, both sessile and pendant drops are studied.The capillary flow, which ...

Abstract:
... The sensory qualities, aroma profile, and microstructural features of instant Pu-erh teas (IPTs) produced by electrostatic spray drying (ESD) were evaluated by sensory and instrumental analyses and compared with those produced by other drying methods (freeze-drying [FD], vacuum drying [VD], and conventional spray drying [CSD]). The sensory qualities of ESDIPT were similar to those of FDIPT, and be ...

Abstract:
... The objective of this work was to evaluate the use of vacuum freezing (VF) as a new method for the freezing stage in the freeze-drying cycle of coffee extract. In this context, the freeze-drying process was evaluated using either vacuum freezing (VF-FD) or contact freezing (CF-FD) as initial stage. The incorporation of VF in the freeze-drying cycle allowed to reduce up to 1/4 of the initial moistu ...

Abstract:
... Probiotic microbes may confer a variety of positive health effects on the host. Until now, development of probiotic products has mainly focused on Lactobacillus and Bifidobacterium species, which generally tolerate the stresses encountered during processing, storage and delivery well. In recent years, newly-discovered gut microbes have gained attention due to their association with healthy host co ...
... Insights into food matrix factors impacting bioavailability of bioactive carotenoids and chlorophylls from fruits and vegetable ingredients are essential to understanding their ability to promote health. The stability and bioaccessibility of carotenoids and chlorophylls were assessed from dehydrated, spray-dried, freeze-dried and fresh spinach ingredient forms using in vitro models simulating uppe ...
