If the pH is reduced to a point where the setting temperature and preparation temperature are similar, the pectin tends to pregel. This results in a nonhomogeneous weaker gel. 3 Biocomposites more susceptible to syneresis.

This can be solved by preparing pectin mixtures at higher pH and then acidifying when ready. LM pectin forms gels in the presence of divalent cations, most commonly calcium. The reactivity to calcium increases with decreasing DE. LM pectins are often used to produce low-sugar jams.

Lignins are amorphous polymers consisting mainly of aromatic units such as guaiacyl, syringyl, and phenylpropane [51]. Plant cell walls are comprised of the middle lamella and the primary and secondary cell walls. The primary cell wall is formed while the cell is growing. It defines not only the rate of growth of the plant cells but also its size and shape. The primary cell wall is composed of 90% polysaccharide and 10% proteins (glycoproteins) [52]. The secondary cell wall is formed after the cell is fully grown and is much thicker, more rigid, and stronger than the primary cell wall.

Apple pomace and sugar beet pulp are also widely used as sources of pectin. This is often waste material from another industry, for example, apple pomace from cider production. Pectin is generally extracted from plant material using hot aqueous mineral acid. The pectin is then isolated from the solution. One of the main challenges for producers is to retain a high molecular weight as pectin is very susceptible to degradation either by enzymes already present in the plant material or by heat during drying and subsequent processing [98].
