Freeze-Drying of banana sample in Frontloader drying chamber

Contamination-free and sterile freeze-drying using lyophilization bag

Freeze-drying is typically used to deal with sensitive and expensive samples as it offers a gentle drying process. One way to avoid contamination in the drying process is the use of a container with membrane that protect samples from contamination and secondly keep product flyout in place which protects multiple samples from cross contamination.

Lyophilisation of fresh banana slices

Freeze drying is a gentle form of drying and may be used to preserve foods without changing their appearance or taste. The freeze drying process includes the freezing of the food sample and subsequent applying a fine vacuum to the frozen sample. Under these conditions, the water in the food will sublimate, hence, the sample dries. In food applications, freeze drying is commonly used to make instant coffee and to dry and conserve fruits, vegetables or herbs.

Lyophilisation of truffles

Truffles are products with limited shelf life and their sensory properties are rapidly lost. Hence, the expensive fungi become less valuable within a few days. Losses of volatile compounds, oxidation and enzymatic reactions are a considerable problem during their storage. Furthermore, the aroma profile is commonly modified as a result of elevated temperature processes or enzymatic reactions. Freeze drying the fungi avoids loss and degradation of volatile compounds due to the low temperatures applied during drying. The aromatic profile of truffles are maintained. Freeze dried truffles can either be rehydrated or directly used in dry form.

Lyophilization of Giloy stem

In traditional Indian medicine, Giloy is one of the most useful ayurvedic herb. Freeze drying is evaluated as a drying method in order to preserve Giloy properties. Freeze drying is known to be one of the most appropriate method for the preservation of natural and biological materials thanks to the oxygen free environment and the low operating temperatures.

Freeze-dried Okra Vegetable

Okra (Abelmoschus esculentus), due to its high moisture content and sensitive structure, is difficult to dehydrate using conventional drying techniques. This application note evaluates the freeze-drying of okra using the Lyovapor™ L-210 freeze-dryer. The low-temperature, low-pressure drying process enables efficient moisture removal by sublimation, resulting in dried okra with low residual moisture and well-preserved structure and appearance. The high-quality freeze-dried okra can stored safely and used for functional food applications
