Introduction

The new method is applicable by means of a simple and inexpensive apparatus suitable for atomizing a defined amount of acid aqueous solution homogeneously. The system does not require specialized labor.

Technical features

The invention deals with a method of production of preserved and semi-preserved vegetables in piece, which are acidified by spraying acid solutions. This treatment is aimed at the pre-stabilization of semi-dehydrated during the drying step of them. A low pH value, is a condition necessary and often also sufficient to inhibit the germination of spores in the production of canned food. The method is simple to apply, safe and reliable.

Possible Applications

• The technology is ready to industrial use;
• Its application concerned the production of:
  • Semidry tomato cloves;
  • Dried tomato cloves.

Advantages

• Reduction of treatment times;
• Improved efficiency of acidifying solutions;
• Elimination of disposal costs for acidifying solutions;
• Minimum investment and operating costs.
