Abstract
Ananas comosus) variety of the Bromeliaceae family was developed from a cross made by Dole between the commercial variety ‘MG-03’ and ‘P-1972’, a patented clone, and has been designated ‘Dole-14’. This new variety differs from its progenitors in having higher carotenoid content, medium acidity, low fiber content, improved aroma, distinct fruit flavor and flesh colors, and a conical to cylinder shaped fruit with a long conical crown. It also shows high tolerance to NDF and less susceptibility to shell cracking. The plant is characterized by long spineless leaves with piping, that are pale to grayish green in color. When unripe, fruit shell is pale green turning to uniform yellow color when ripe, and the flesh develops a deep golden color at maturity.
A leafy vegetable having a core end and a leafy end is processed after being harvested. The harvested leafy vegetable is transported to a trim area on a conveyor. A first cutting implement located in the trim area trims a portion of the core end. A second cutting implement located in the trim area trims a portion of the leafy end. The first and second cutting implements are spaced a set distance apart, which defines an amount of the leafy vegetable remaining after the portions of the core and leafy ends are trimmed. As the portions of the core and leafy ends of the leafy vegetable are being trimmed by the first and second cutting implements, a set of one or more nozzles located in the trim area sprays a rinsing liquid on cut sites on the leafy vegetable to rinse off natural juices exuding from the cut sites.
Lettuce can be commercially harvested by removing the bottom portion of a head of lettuce to obtain only the top portion of the head. After the top portion of the head is obtained, a center section of the top portion of the head is removed to leave a cup-shaped portion of the head. The bottom portion of the head is removed and the center section of the top portion is removed in the field in which the head is harvested.
