Pineapple is one of the popular fruits and is liked by majority of the people irrespective of their age or group. It is an example of a multiple fruit: multiple, spirally arranged flowers along the axis each produce a fleshy fruit that becomes pressed against the fruit of adjacent flowers forming what appears to be single fleshy fruit. Pineapple is commonly use in desserts and other types of fruits dishes or served on its own. Pineapple is the only bromeliad fruit in widespread cultivation Pineapples served as one of the major fruits exports of the Philippines. For that most of the pineapple farmers, its production has the always been the major source of livelihood. As the case with most the fruits vegetable their availability is limited during the year. Many techniques have been developed to make available during off season. The pineapple is a herbaceous perennial which grows to 1.0 to 1.5 meters (3.3 to 4.9 ft) tall, although sometimes it can be taller. In appearance, the plant itself has a short, stocky stem with tough, waxy leaves. When creating its fruit, it usually produces up to 200 flowers, although some large-fruited cultivars can exceed this. Once it flowers, the individual fruits of the flowers join together to create what is commonly referred to as a pineapple. After the first fruit is produced, side shoots (called 'suckers' by commercial growers) are produced in the leaf axils of the main stem. These may be removed for propagation, or left to produce additional fruits on the original plant. Commercially, suckers that appear around the base are cultivated. It has 30 or more long, narrow, fleshy, trough-shaped leaves with sharp spines along the margins that are 30 to 100 centimeters (1.0 to 3.3 ft) long, surrounding a thick stem. In the first year of growth, the axis lengthens and thickens, bearing numerous leaves in close spirals. After 12 to 20 months, the stem grows into a spike-like inflorescence up to 15 cm (6 in) long with over 100 spirally arranged, trimerous flowers, each subtended by a bract. Flower colors vary, depending on variety, from lavender, through light purple to red. The ovaries develop into berries which coalesce into a large, compact, multiple accessory fruit. The fruit of a pineapple is arranged in two interlocking helices, eight in one direction, thirteen in the other, each being a Fibonacci number. Pineapple carries out CAM photosynthesis, fixing carbon dioxide at night and storing it as the acid malate and then releasing it during the day, aiding photosynthesis.
Canned, peeled and cored pineapple slices and juice are some of the products of the pineapple industry. Pineapple is consumed as dessert, in fruit salads, while making cakes and pastries and etc. thus there is a large number of consumers who would like to consume cored pineapple slice or juice. The development of the local pineapple industry depends greatly on the adaption of new technologies as well as available market and credits growers commitment. Although at presents production practices for small scale enterprises are still traditional due to low adaptation of these new production technologies and primarily because of its high cost. In addition manual peeling and coring a pineapple is still a part of some small scale enterprises although it has no cost requirement. This requires more time and manpower to produce peeled and cored pineapple slices. Equipments aided method, on the other hand requires proper usage to avoid accident. As a solution to this problem this...
