Ultrasound extraction of phenolic compounds from coconut (Cocos nucifera) shell powder

Rodrigues, Sueli, Pinto, Gustavo A.S.·2007·Journal of Food Engineering

Abstract

Coconut is a tropical fruit largely consumed in many countries. In some areas of the Brazilian coast, coconut shell represents more than 60% of the domestic waste volume. The shell is composed mainly of lignin and cellulose with chemical composition very similar to wood. As several kinds of wood are used as a phenolic source to produce extracts for artificial aging of alcoholic beverages, in this work, the coconut shell was evaluated as a source of phenolic compounds. The coconut powder was submitted to different toasting temperatures and the phenolic compounds were extracted by the application of ultrasound. The ultrasound extraction methodology has been studied as a low cost alternative in substitution to solvent reflux extraction. The experiments were done according to a factorial experimental planning and the effects of toasting time, toasting temperature and extraction time were evaluated through response surface methodology. The results indicate that high amounts of phenolics can be extracted from coconut shell by ultrasound assisted extraction technology, and that the extraction time was the most significant parameter for the process.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The lyophilized extract and fractions, as well as ethyl acetate extracts, from the C. nucifera fiber are rich in polyphenols, compounds such as catechins, epicatechins, tannins, and flavonoids.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
