摘要:
System, method and equipment for the application of plant protection products under controlled post-harvest conditions, preferably on dessert grapes and other fruit, by means of spraying equipment with an electrostatic effect which expels through spray nozzles whose droplets are negatively charged, being attracted by positive charges of the object to be treated, thereby achieving uniform covering with excellent penetration in the bunch of fruit. The treatment is particularly suitable for controlling fungal diseases and especially the disease called acid rot.
摘要:
Methods and apparatus are provided for decreasing the bacteria count of a food commodity eg. meat without affecting its overall organoleptic quality (taste, odor, and color). This is accomplished using a treatment fluid comprising ozone, which is injected into a treatment chamber containing the food commodity. Some water is preferably added to obtain better contact of the ozone with the food by forming a thin film of ozonated water on the food surface. Spices and/or other ingredients may preferably be added with the water. The food is placed in a tumbler and the tumbler is set in motion. During treatment good contact between the treatment fluid and the food commodity is obtained by reversibly oscillating the tumbler. A log reduction of 40 % or more in bacteria count may be obtained as compared without the ozone.
摘要:
A mixture of hydrogen peroxide and glycerol has been found to be a particularly effective composition as a preserving additive for raw materials, in particular foodstuffs. An organic acid, such as valeric acid, can be added to the mixture as stabiliser. By atomising the mixture, in combination with gentle shaking of the product to be treated in a device provided with means suitable for this purpose, an efficient treatment is effected with relatively low consumption of the preserving mixture. The shelf life of the products treated can be further increased by drying the surface thereof using sterile air.
摘要:
Provided are foodstuff treatment systems that are convertible between a processing mode in which foodstuffs are processed (e.g., disinfected) and a clean-in-place mode in which the system operates to clean material (e.g., biological buildup) that has accumulated within the system.
摘要:
A needleless injection device and method for injecting a food subject is disclosed in which one or more types of liquid food additive are individually and/or simultaneously delivered to a food subject within a sealed injection chamber or compartment. The needleless injection device and method of the present invention utilizes rapid, high pressure injection bursts to completely and uniformly inject the food subject, allowing different food subjects or different food additives to be sequentially injected in an efficient and instant manner. The needleless injection device and method for injecting minimizes contamination by totally enclosing the injection process within a sealed chamber, and by eliminating the need for the injection nozzles to contact, or be placed immediately adjacent to the food subject.
摘要:
The invention relates to a method for preserving fresh foodstuff such as fruit, salad or vegetables that is processed ready for use, according to which the food tem is immersed in a liquid in which a mixture of preservatives is dissolved, the concentration of the mixture in the liquid is constantly measured, and the determined actual value is compared with a desired value. If the actual value is lower than the desired value a corresponding amount of the mixture is added to the liquid.
