“…PS samples at different concentrations all formed a spongy network structure but with different degrees of cell density. This indicates that under the HE-3DP conditions, PS underwent sufficient gelatinization and the interaction between the diffused starch chains allowed the formation of a crosslinked network structure (Huang et al, 2017). Under the same printing temperature (70 °C), the PS concentration (10-30%) significantly influenced the morphology of the printed gel.…”

“…Starch are semi crystalline particles of granulose derived by high molecular weight amylose polymers with amylopectin branches. 14 The crystalline form of starch granules contain water in smaller amount thus provide greater stability and difficulty in being hydrolyzed by the enzymes. And hence, the structural modification occurs by gelatinization via physiocochemical, chemical, biological or combinatorial pretreatment methods are considered pivotal.…”

Environmental concerning factors responsible for carbon dioxide emissions and depletion of petroleum based fuel are the driving factors for the search of alternative fuels like biodiesel. The growth of microalgal cells and their metabolic activity toward lipid production could be controlled by the nutrient factors employed in production media. The lipid accumulation ability of the microalgal strains could be influenced by the deprivation of vital chemicals like carbon, nitrogen, calcium and magnesium. In the part of commercializing microalgal based biodiesel, cost effective measures in oil extraction and downstream processes have to be considered. Huge varieties of microalgal cellular pretreatment methods are employed to enhance cellular disintegration so as to facilitate oil extraction by structural modification of carbohydrates present in cell wall. The diversified methods used for microalgal pretreatment encompass chemical, thermal, biological, mechanical or combinatorial approaches. Among all the pretreatment methods chemical methods are greatly advantageous while concerning the feasibility in energy and time consumption. Combinatorial approaches like thermochemical pretreatment or microwave assisted extraction methods are very successful in terms of feasible energy production under limited time consumption. Above all, genetic engineered microbes which could be able to withstand suitable pretreatment methods were developed. This present review tried to explore the activity of chemical parameters and also delineate the nutrient deprivation factors involving in the cellular metabolism of microalgal biomass for lipid production.

“…In starch granules, the outmost spherical blocklets are closely arranged to form the shells of granules which prevent the denaturant from entering the starch granules. Therefore, the chemical activity of starch granules is inert (Huang et al, ). Famous modified starch companies such as the CPC International and the NSCC invested a lot of money in the research of advanced production equipment of modified starch.…”

Background and objectives The chemical activity of starch granules is inert. The purpose of this study was to reveal the mechanism of producing high‐quality modified starch by advanced equipment. Findings There were pores and central cavities with loose structure in mung bean starch granules, so water could enter the starch granules through the pores under high hydrostatic pressure treatment. The starch molecules could be hydrated, and starch granules could even be gelatinized. The reaction efficiency (RE) of cationic starch increased to 32.20% and the other qualities (solubility, swelling degree, and viscosities) were significantly improved after 100 MPa treatment. The RE and other qualities of cationic starch changed differently after 200 and 400–600 MPa treatments. Conclusions High hydrostatic pressure could produce significant mechanochemical effect on starch granules, so the structures and properties of mung bean starch were changed markedly, and the quality of cationic starch was improved. Significance and novelty The mechanism of producing high‐quality modified starch by advanced equipment was revealed using mechanochemical theory, which could lay a theoretical foundation for the manufacture of high‐performance modified starch industrial equipment in the future.
