How to make freeze-dried fruits
In recent years, freeze-dried dried fruits have become a popular product in the healthy snack market due to their high nutritional retention, crisp taste, and easy portability. This article will introduce in detail the production process, advantages and market trends of freeze-dried dried fruits, and attach relevant data comparisons.
1. Preparation steps of freeze-dried fruits
Freeze-drying technology (freeze-drying) is a process that retains food nutrients through low-temperature dehydration. It is mainly divided into the following steps:
| steps | Operation content | Technical points |
|---|---|---|
| 1. Preprocessing | Wash, peel and cut into pieces | Make sure the fruit is pollution-free and uniform in size |
| 2. Freeze | -30℃ to -50℃ quick freezing | Prevents ice crystals from damaging cell structures |
| 3. Vacuum drying | Low temperature sublimation moisture | Pressure is controlled at 0.01-0.1 mbar |
| 4. Packaging | Nitrogen-filled seal | Moisture-proof and oxidation-proof |
2. Advantages of freeze-dried dried fruits
Compared with traditional drying of fruits, freeze-drying technology has significant advantages:
| Comparative item | Freeze-dried fruits | Dried fruits |
|---|---|---|
| Nutrient retention rate | More than 90% | 40%-60% |
| Taste | Crispy, original flavor | Hard, may be scorched |
| shelf life | 12-24 months | 6-12 months |
3. Market trends of freeze-dried fruits
According to the analysis of hot topics across the Internet in the past 10 days, the market demand for freeze-dried dried fruits continues to grow, mainly reflected in:
1.The healthy snack track is booming: Consumer demand for low-sugar, additive-free snacks is rising, and freeze-dried dried fruits have become the first choice to replace potato chips and candies.
2.New tea drink pairings: Freeze-dried fruit slices are widely used for decoration of milk tea and fruit tea to enhance the appearance and taste of the product.

4. Common freeze-dried fruit types and price reference
| Fruit types | Weight ratio after freeze-drying (%) | Market price (yuan/100g) |
|---|---|---|
| strawberry | 10-12 | 25-35 |
| mango | 15-18 | 20-30 |
| durian | 20-25 | 50-80 |
5. Feasibility of home-made freeze-dried fruits
Although professional freeze-drying equipment is expensive (about 100,000 yuan or more), small household freeze-drying machines (2,000-5,000 yuan) are gradually becoming popular. Things to note when making your own:
1. Choosing high-sugar fruits (such as bananas and apples) is more likely to succeed;
2. The slice thickness is controlled at 3-5mm;
3. Drying time takes 8-24 hours, depending on the power of the equipment.
As a product of modern food technology, freeze-dried dried fruits take into account both health and convenience, and have huge market potential in the future. Consumers can judge the quality by looking at the color (whether it is natural) and texture (whether it is crispy) when purchasing.
