Advantages of belt dryer banana slices
Low raw material costs and stable seasonal supply. Bananas are one of the most stable fruits in terms of supply throughout the year, with prices at a low level. Compared to seasonal fruits such as strawberries and cherries, bananas are almost unaffected by the local rainy season in Shanghai, with abundant and affordable sources, making them suitable for mass production. two Natural sweetness is high, almost no need to add sugar. Bananas themselves have a high sugar content (about 20% when ripe), and after belt dryer, the sugar is concentrated, resulting in a very natural and rich sweetness. Unlike dried fruits like apples and lemons, which tend to be sour and require additional sugar or honey for seasoning. This is also worry free during humid seasons - high sugar foods naturally inhibit bacteria and are more resistant to storage than low sugar fruits. three The belt dryer time is short, the efficiency is high, and the banana fruit has a soft texture and relatively moderate moisture content (about 75%). After slicing, the belt dryer speed is faster than that of hard fruits such as apples and pears. 3-4mm thick banana slices can usually be dried in 6-8 hours at 55-60 ℃. Apple slices of the same thickness require 10-12 hours. In May, when the humidity is high in Shanghai, the shorter the belt dryer time, the lower the risk of exposure to humid air and the higher the success rate. four The finished product has a unique taste and high market acceptance. After belt dryer, banana slices have a crispy or soft texture (depending on the thickness of the slices and the degree of belt dryer), with a natural caramel aroma. This flavor is actually more popular during humid seasons - many people have a bad appetite in summer, so banana slices as a snack can replenish energy without being as greasy as fried potato chips. five Strong antioxidant capacity and less prone to browning. Compared to fruits such as apples and pears that quickly oxidize and change color after cutting, bananas have a relatively slower oxidation rate. Its flesh contains a high amount of polyphenol oxidase inhibitors, which can maintain a light yellow color for a long time even without soaking in salt water after slicing. This is an advantage during humid seasons - it does not require complex anti-oxidation treatment, saving time and effort.
