Cum se sterilizează corect borcanele pentru murături și alte conserve. Greșelile care împiedică închiderea etanșă a capacelor

Proper sterilization of jars is crucial for safe food preservation. Jars must be checked for defects, cleaned, and kept warm before filling. Thermal processing is necessary after filling to ensure airtight sealing. Common mistakes include leaving food residues on jar rims and improper cap usage. Jars should be sterilized by boiling for short processing times, while longer processing requires no prior sterilization. After filling, the rim must be cleaned, and the right headspace maintained. Caps should not be overly tightened, and jars should cool undisturbed to ensure proper sealing. Safety depends on food acidity and processing methods, with low-acid foods requiring pressure canning.
