Background

Foliage is another word for the leaves of a plant. Leaves can constitute a significant biomass resource, particularly in forestry residues.

Analysis of Foliage at Celignis

Celignis Analytical can determine the following properties of Foliage samples:

If you would like us to analyse your Foliage samples then please select the appropriate analysis packages from our list.

Cellulose Content of Foliage

It is usually the case that the cellulose content of foliage is significantly less than in the main stem of the plant.

The chemical composition of foliage can vary significantly, according to the plant. For example, hardwood trees typically have broad leaves whilst softwood trees have needles. Furthermore, whilst hardwoods are deciduous, meaining that their leaves are shed each year, softwood conifers are evergreen.

Foilage from softwoods tends to have a higher cellulose content than foliage from hardwoods, but this will depend on the species in question.

Hemicellulose Content of Foliage

The hemicelluloses in foilage from softwoods tend to have more mannose than xylose present, whilst for hardwood foliage mannose is a minor component with xylose being the most abundant hemicellulosic sugar.

Lignin Content of Foliage

Lignin content can vary significantly in foliage, depending on the plant species in question. Foliage can also contain a significant, and highly variable, extractives content.

Starch Content of Foliage

Starch content can be relatively high in foliage but will vary according to the maturity of the plant. The content can also vary significantly between tree species.

Uronic Acid Content of Foliage

Uronic acid content tends to be higher in foliage than in the stems of plants.However, the uronic acid content and composition can vary according to the type of foliage and its stage of maturation.

Enzymatic Hydrolysis of Foliage

We can undertake tests involving the enzymatic hydrolysis of Foliage. In these experiments we can either use a commercial enzyme mix or you can supply your own enzymes.

We also offer analysis packages that compare the enzymatic hydrolysis of a pre-treated sample with that of the native original material.

Ash Content of Foliage

It is usually the case that foliage contains significantly more ash than the stem of the plant. Ash content can be highly variable between leaves of different species.

Heating (Calorific) Value of Foliage

The heating value of foliage will depend on chemical composition and moisture content. Some foliage can have attractive heating values, on a dry matter basis, due to the presence of significant amounts of high calorific value extractives.

Bulk Density of Foliage

At Celignis we can determine the bulk density of biomass samples, including Foliage, according to ISO standard 17828 (2015). This method requires the biomass to be in an appropriate form (chips or powder) for density determination.

Basic Density of Foliage

At Celignis we can determine the basic density of some suitable biomass samples. The method requires the biomass to be in an appropriate form (chips) for density determination.
