Four disadvantages of spice dryer

High temperatures can easily lead to the loss of core aroma. The essential oils in spices have extremely low boiling points, mostly starting to volatilize at 60°C–90°C. However, traditional hot-air drying and oven drying generally involve temperatures ranging from 80°C to 120°C. This "high-temperature intense drying" can cause the most precious light aroma compounds to volatilize completely, resulting in dried spices that smell unfragrant and taste tasteless when cooked, leaving only a woody or astringent flavor.

Four disadvantages of tomato drying

During the drying and dehydration process, some heat-sensitive nutrients are lost. Some water-soluble vitamins (such as vitamin C) in tomatoes are easily lost due to heating and oxidation. Therefore, the vitamin C content and overall nutritional value of dried tomatoes are slightly lower than those of fresh tomatoes.

Four disadvantages of carrot drying

rying can cause the loss of some key nutrients. Although the dietary fiber and minerals (such as potassium and calcium) in carrots can be well preserved, water-soluble vitamins such as vitamin C and some B vitamins are easily oxidized and destroyed when exposed to heat and prolonged exposure to air. In addition, vitamin A (carotene) is also prone to oxidation at high temperatures, resulting in lower overall nutritional value compared to fresh carrots.

Q&A on Drying Meat and Chili

Choose fully ripe, bright red, and undamaged chili peppers, wash the surface sediment with clean water, and be sure to thoroughly dry the water with kitchen paper. To speed up the drying process and prevent internal moisture retention, it is recommended to cut the chili peppers in half vertically or into evenly thin slices of about 0.5 centimeters. Please wear gloves when handling to avoid skin irritation caused by capsaicin.

Advantages of IQF frozen strawberries

Q1: What is IQF frozen strawberry? What is the difference between it and traditional frozen strawberries? A: IQF stands for "Individually Quick Frozen". Unlike traditional frozen strawberries that easily freeze into a large piece, IQF technology utilizes ultra-low temperature (usually between -30 ° C to -40 ° C) and rapid freezing technology, allowing each strawberry to independently and quickly freeze in the freezing equipment

Three key "avoidance" details that determine the success or failure of strawberry freeze-drying

The eutectic point is the lifeline: the eutectic point of strawberries is about -2 ℃ 5. In the sublimation drying stage, the temperature of the material itself (not the partition temperature) must not exceed this value, otherwise the ice crystals will melt and the flesh structure will collapse instantly
