Title: Improved process of treating vegetable produce
IPC: A23L11/00
Filed: 1925-11-30
Abstract: 266,069. Nesbitt, S. G. M., Butler, J. B., and Drumm, J. J. Nov. 30, 1925. Preserving fruit and vegetables. - In preserving vegetable produce, including fruit, the produce is impregnated with a standard non-toxic alkaline buffer solution, so that peas, French beans, spinach, and other chlorophyll-containing produce will retain their colour when sterilized and packed in sealed containers. The treatment is preferably adjusted to give a liquor having a PH value of 7.0-8.3 in the containers after sterilization. The protoplasm is first killed, e.g. by scalding, to render the materials permeable to the buffer solution. A solution containing 4-8 parts by weight of sodium di-hydrogen phosphate to 100 parts of water may be used, or part of the phosphate may be replaced by an equivalent amount of sodium bicarbonate. A mixture of disodium hydrogen phosphate and sodium dihydrogen phosphate may be employed when it is desired to vary the PH value somewhat, more especially with produce not containing chlorphyll. For packing liquor, a 5 per cent disodium hydrogen phosphate with the usual sugar-salt solution may be used, or a molecular equivalent of magnesium hydroxide may be employed. When permissible, soluble preservations, such as benzoates or sulphites, or essential oils, such as cloves, cassia. &c., may be added to accelerate sterilization and to enable lower concentrations of the buffer solutions to be used. Examples are given of the packing of peas and spinach. Where a less bright colour is preferred. a more dilute buffer solution is employed. In this case a small amount of sodium phosphate may be added. Impregnation with the solutions may be assisted by first reducing and then increasing the pressure.
