Suitability of rose hips for freezing
Rosa L.
For rose hips, freezing is a technological method for improving raw material quality that simulates the effect of natural frosts to increase sugar content and simplify processing.
In the reference 595 varieties crop Rose, where this is mentioned in the description.
Freezing rose hips for 24–48 hours is used as a quality management tool. Low temperatures cause partial destruction of cell walls, promoting the conversion of starches into sugars, which improves flavor characteristics and facilitates the production of juices, purées, and syrups.
Unlike traditional drying, freezing helps avoid thermal degradation of biologically active substances and color changes in the raw material. Exposure of fruit left on the bush to temperatures in the range of -3°C to -12°C does not significantly reduce vitamin C levels while increasing the content of vitamin P and oligosaccharides.
