Coconut meal

Formulating a hypothesis It is hypothesized that copra (coconut meal), another complex natural material, is the solid found in the oil and in the centrifuge. 

Interpretation/report Coconut meal, not adequately removed during the oil extraction process, is the haze in the oil and is building up in the centrifuge.

There are problems associated with the use of copra cake in feed. As the amount of cake in the feed increases, its palatabihty decreases. Copra meal tends to be less digestible than fresh coconut meal. Despite a protein content of greater than 20%, the addition of methionine and lysine improves growth and feed utilization. The method of oil extraction does not appear to influence the quality of meal produced. Neither expeller-extracted nor solvent-extracted copra meal, at levels of 10-14% in poultry diets, caused any difference in egg production, mortahty, or efficiency of feed conversion (61). 

Coconut meal has the valuable property of absorbing up to half its own weight of molasses and as a result is popular in compounding. 

Copra. This is the dried meat of the coconut from which the oil is to be extracted, yielding coconut oil and coconut meal or copra meal. The oil is generally extracted by either (a) continuous mechanical screw presses, or (b) hydraulic... 

A similar product called temp bongkrek is sometimes made from coconut meai Tempeh made from coconut meal may become poisonous, but tempeh made from soybeans never does. 

In addition to the separation of coconut oil from a coconut milk emulsion, enzyme treatment can also be used to extract coconut oil from finely divided copra meal. Coconut oil extraction based on the enzymatic action of polygalacturonases, a-amylase and proteases on a diluted coconut paste has been tested (McGlone et al., 1986). After the reaction with enzymes, the mixture gave three phases upon centrifugation. The upper phase contained high quality coconut oil and the middle layer and the lower layer contained water and coconut meal respectively. This process gave a yield of 80%, which is a much higher yield compared to other traditional wet extraction methods. Enzyme assisted extractions have also been used to extract coconut oil from powdered copra. The crude commercial enzyme used in this study contained a-amylase, neutral protease, acid protease, cellulase/hemicellulase, and pectinase. The enzyme treatment in this process can be considered as a pretreatment of copra prior to the oil extraction. The enzyme was added 1% rate of the copra and allowed to stand for 30 min. After enzyme treatment, the meal was extracted by hot water and the emulsion was boiled to evaporate water. This enzyme pretreatment of copra prior to the extraction improved the yield of coconut oil by 50% compared to the same extraction procedure without enzyme... 

C. is the fruit from a tree of the Pacific tropics and the source of copra (the dried meat of the opened nut), which by oil extraction is manufactured into coconut oil and coconut meal. It represents the most important source of lauric oils (- fats and oils).
