![]() Therefore, choosing the best method must be made based on the purpose of the process and the final product criteria.Ĭitation: Hesti Kurniasari, Wahyudi David, Laras Cempaka, Ardiansyah. In conclusion, drying has different effects on ginger in terms of bioactivity. After drying treatment there were significant different on total flavonoid and antioxidant activity and there were not significant on total phenolic content and 6-gingerol content of ginger. The drying techniques have different effects on the optimum levels of ginger characteristics. There are 13 articles from 2010 to 2020 that met the inclusion criteria. A meta-analysis investigation was conducted to identify a study that evaluated the effects of drying techniques on the levels of bioactivity in ginger. This study aimed to review the studies that have evaluated the effects of drying techniques on the bioactivity of ginger. Drying is commonly used in the processing and preserving of ginger and affects the characteristics of the final ginger product. Not a science fan? Don’t worry – leave it to us, and just sit back and enjoy our delicious treats.Ginger is a spice with various uses for humans, such as flavoring agents and nutraceuticals. Freeze-dried foods can last up to 25 years! This makes it a popular option for campers and adventurers, or anyone who wants their favourite snacks to last.įreeze-drying can seem like a mysterious process, but we hope this blog helped you understand the science behind it a little more. It helps us keep things new and exciting, so we never get bored of our favourite treats.Īs a plus, since freeze-drying removes the moisture from the food, it extends its shelf-life. By changing the texture of our favourite candies, it’s like discovering a whole new treat! Candies that are normally soft become crunchy, and tiny candies turn into big bites. And Jolly Ranchers swelled up to about the size of a golf ball when we freeze-dried them (stay tuned for this review)! Remember our post about Jell-O? These candies turned into these super crunchy little bites. By removing all the water from the product, the most noticeable change you’ll see is in the texture of the food. When freeze-drying, almost none of the nutrients are removed from the food, so the flavour stays the same (sometimes it even gets sweeter!). These steps sound complicated, but here at that sweet lyfe, we like to use the Harvest Right freeze-dryer, which automates these steps and makes it super easy!Īfter these three steps, you’re left with a tasty, yummy freeze-dried candy. ![]() Here, the remaining water molecules are removed by raising the temperature even higher. The rest of the water is removed in the third step, adsorption. About 95% of the product’s water is removed in this step. By doing this, the ice turns directly into a gas, instead of a liquid (this is what sublimation means). In this step, you lower the pressure and raise the temperature. This allows sublimation, the next step, to occur. In this step, the food is frozen at extreme temperatures so that the water in the food turns into ice. These terms sound very technical, but read on to hear how they work! ![]() It’s an interesting process that involves three main steps: freezing, sublimation, and adsorption. We take these foods and, using our freeze-drier, remove all the water content to give you our tasty, delicious freeze-dried treats.įreeze-drying is a bit more complicated than just removing the moisture from food. You can freeze-dry candy, fruit, vegetables, and even complete meals! Here at that sweet lyfe, we’ve tried everything from Skittles to lemons to Christmas rum cake. If you want to learn about the science behind our freeze-dried experiments, keep reading!įreeze-drying, in its simplest terms, is the process of removing all the moisture from a piece of food. So you’ve been following our blog for a while now and reading all about our freeze-drying adventures! But you may be left wondering: what exactly is freeze-drying?Īs the internet’s freeze-drying experts, we’re here to give you all the facts about freeze-drying: what it is, how it works, and what you’re left with.
