Lansium domesticum, also known as langsat, buahluku or lanzones, is a species of tree in the Mahogany family. The plant, which originates from western Southeast Asia, bears edible fruit. It is the provincial flower for the Indonesian province of South Sumatra.The tree is average sized, reaching 30 metres (98 ft) in height and 75 centimetres (30 in) in diameter. Seedling trees 30 years old planted at 8 x 8 meter spacing can have a height of 10 meters and diameter of 25 cm. The trunk grows in an irregular manner, with its buttress roots showing above ground. The tree's bark is a greyish colour, with light and dark spots.

Its resin is thick and milk coloured. Coffee is a brewed beverage with a dark, slightly acidic flavor prepared from the roasted seeds of the coffee plant, called coffee beans. Green (unroasted) coffee is one of the most traded agricultural commodities in the world. Coffee can have a stimulating effect on humans due to its caffeine content. It is one of the most-consumed beverages in the world. The researcher decided to use lanzones seeds instead of throwing it and decided to use the seeds as coffee to know if it could be a good alternative to the commercial one. B. Statement of the Problem

The main problem of the study is to make coffee from lanzones seeds. It also answers the following problems: 1. What are the characteristics of the different lanzones seeds coffee samples in terms of: Color

Aroma Taste Acidity 2. What is the acceptability of the different lanzones seeds coffee samples prepared? 3. Is there a significant difference on the characteristics and acceptability of the different lanzones seeds coffee samples?

C. Hypothesis of the Study Null (Ho) There is no significant difference among the different lanzones seeds coffee samples developed in terms of their color, aroma, taste, and acidity. Alternative (Hi) There is significant difference among the different lanzones seeds coffee samples developed in terms of their acceptability. D. Significance of the Study This study aims to produce coffee using lanzones seeds as substitute. The study is important because lanzones is abundant in the Philippines. Everybody can benefit of the result of the study unless a coffee drinker. It would recycle the lanzones seeds instead of being thrown away which a lot of people consider it as waste. E. Scope and Limitation

The proposed study is limited to producing coffee out of lanzones seeds. Three samples are going to be prepared with different lanzones seed concentration and same amount of water for comparison purposes in which one of the samples is pure commercial coffee. The commercial coffee going to be used is Nescafe Classic. The samples are going to processed by the basic methods of making coffee: roasting, grinding, and brewing. The products are then evaluated by a minimum of thirty (30) evaluators of coffee-drinker to determine its characteristics and level of acceptability. Each of the evaluators are going to be provided an individual score sheet to evaluate each samples made. The experiment is going to be done at the residence of the researcher on 2015. F. Conceptual Framework

Scientific Name: Lansium domesticum It is a species of fruit-bearing tree belonging to the family Meliaceae; a native to Malaysia and Indonesia. Season in the Philippines: Lanzones is abundant from July to November (rainy season) typically that grown mostly in parts of Paete, Laguna and abundance also in the Northern part of Mindanao like Butuan, Cagayon de Oro and Camiguin (popularly known for their Lanzones festival). Healthy benefits: Contains Vitamin C and E, and has a good source of antioxidants properties. Lanzones also can prevent diarrhea as I try it myself which is effective by eating the meat of the fruit.

Taste and texture: Lanzones is sweet depending on the ripeness and quality. It really tastes good (hindi nakakasawa) that once you started eating you just can’t stop it although the seed has a bitterness taste some eat the seed. The texture of the fruit outside cover has a typically brown color and once you peel it, the meat of the fruit is somewhat juicy white which is very easy to eat.

Lanzones or Lansium domesticum is a species of fruit-bearing tree belonging to the family Meliaceae. The plant has pinnate compound leaves that grow to a length of around twenty to fifty centimeters long per leaf. Each fully-grown leaf has five to seven slightly-leathery; obovate leaflets that can reach a length of twenty centimeters each. A very prominent midrib bisects each dark green, glossy leaflet. Fruits are ovoid, round orbs around five centimeters in diameter, usually found in clusters of two to thirty fruits along the branches and trunk.

Each round fruit is covered by yellowish, thick, leathery skin. Underneath the skin, the fruit is divided into five or six slices of translucent, juicy flesh. The flesh is slightly acidic in taste, although ripe specimens are sweeter. Green seeds are present in around half of the segments, usually taking up a small portion of the segment although some seeds take up the entire segment's volume. In contrast with the sweet-sour flavor of the fruit's flesh, the seeds are extremely bitter. The fruit taste has been compared to a combination grape and "perfect" grapefruit with no bitterness. Yet the seeds if bitten have the bitterness of a grapefruit yet stronger. The sweet juicy flesh contains sucrose, fructose, and glucose.
