“…Pectin is a natural polymer existing in the fruits, roots, stems and leaves as a component of the cell walls of most plants. Pectin acts as an accompaniment of fibrin and both of them are constituents of the intermediate joint of the adjacent cells and make the plant tissues cells tightly bound together 179 .…”

Natural biomacromolecules have attracted increased attention as carriers in biomedicine in recent years because of their inherent biochemical and biophysical properties including renewability, nontoxicity, biocompatibility, biodegradability, long blood circulation time and targeting ability. Recent advances in our understanding of the biological functions of natural-origin biomacromolecules and the progress in the study of biological drug carriers indicate that such carriers may have advantages over synthetic material-based carriers in terms of half-life, stability, safety and ease of manufacture. In this review, we give a brief introduction to the biochemical properties of the widely used biomacromolecule-based carriers such as albumin, lipoproteins and polysaccharides. Then examples from the clinic and in recent laboratory development are summarized. Finally the current challenges and future prospects of present biological carriers are discussed.

“…Furthermore, pectic acid can react with Ca 2+ to form calcium pectate, a molecular gel that can exist in the intercellular space, which retains the cell membrane in an inherent position after thawing, thereby enhancing the antiwrinkle behavior and antidestructive effect of cells [13]. Some studies also proved that calcium pectate has a great adhesion effect among the plant cell wall and cell membrane, which can prevent cell shrinkage and provide standby for tissues [14]. At present, apart from the addition of exogenous texture retaining agent, endogenous PME and Ca 2+ have the same effect.…”

Heat-soak and quick freezing could deteriorate the texture of vegetables. In this work, it was found that calcium chloride-sodium alginate (SA) could improve the appearance, brittleness, and chewiness of processed Heracleum moellendorffii (HM), a kind of popular nutritious wild vegetable in China. The effect resulted from the increase of calcium content in the vegetable, which was closely related to the ratio of calcium chloride to SA, the concentration of texture retaining agent, and soaking time significantly ( P < 0.01 ). The best way to maintain the texture was to soak HM in 4 g/L of calcium chloride-SA (mass ratio 1 : 2) at 50°C for 30 minutes. The calcium content was increased to 71.56 mg/100g, and the brittleness and chewiness were 4630 gf and 2583.33 gf, respectively. The microstructure found that calcium could adhere to an inherent position on the cell membrane and protected the sample from cell damage and chloroplast spilling from the cell during thawing and quick freezing. The results showed that calcium chloride-SA treatment may be a promising method to improve the texture of vegetables during quick-frozen storage.

Gardenia ( Gardenia jasminoides J. Ellis) is regarded as an edible medicine plant in China. Here, gardenia flower polysaccharide fraction (GFPF) was extracted by water at 90°C and its chemical composition, rheological properties, and antioxidant activities of GFPF were investigated. The GFPF extraction yield was 18.04 ± 1.81% (W/W) and mainly comprised neutral sugars (46.83 ± 3.14%), uronic acid (35.21 ± 0.17%), protein (1.63 ± 0.34%), and total phenol (9.49 ± 0.08 mgGAE/g). Galacturonic acid (41.05 ± 0.59%) was the main monosaccharide, and galactose, glucose, arabinose, rhamnose, xylose, mannose, and glucuronic acid were also detected in GFPF. Its degree of esterification was 32.76 ± 1.52%. FT‐IR spectra analysis showed a similar absorption pattern between GFPF and pectin from apple. The results suggested that GFPF was low methoxy pectin. Thermogravimetric analysis and zeta potential analysis indicated that the pectin was stable under high temperature and alkaline condition. Steady rheology showed that the GFPF dispersion was a shear thinned pseudoplastic fluid with high apparent viscosities at concentration above 2%. The degree of pseudoplasticity of the solutions increased with the concentrations increased and the temperatures decreased. DPPH and ABTS free radical scavenging assay indicated that GFPF had relatively high antioxidant activity. The results showed that gardenia flower was rich in pectin polysaccharides with low methoxy pectin. It had high apparent viscosities at concentration above 2% and had good antioxidant activity. The data suggested that GFPF can be a new resource of low methoxy pectin with potential application as thicker or gelling agents in food industry.
