Abstract: A handheld air injector apparatus that is to be used in conjunction with an airtight closeable container where the injector apparatus is to connect with a container and supply air within the container to a preselected level.

Abstract: A preservation process and apparatus which serves to preserve respiratory agricultural produces, such as plants, flowers, fruits, vegetables, cereal grain and the like, without necessitating the use of chemical coatings, chemical preservatives, fumigants, or the like. The invention is predicated on the concept of imposing a small positive pressure gradient on the product from the outside to the inside. The selected positive pressure gradient may be of the order of 1-5 psi, which is sufficient to insure positive partial vapor pressure gradients from ambient partial vapor pressure to the internal partial vapor pressure of the product. Such a positive pressure sufficient to ensure a positive partial pressure gradient neutralizes the outward diffusion of moisture and nutrients from the product, and it also retards the respiration rate and thus retards its rated maturity.
