Starch, the predominant carbohydrate in nature, serves as the primary energy source for various physiological activities in humans. Characteristic starches from tropical crops, such as cassava, banana, jackfruit, and breadfruit, mango, and canistel have gained attention due to their diverse and multiscale structures, distinct physicochemical properties, processing characteristics, and myriad applications. This review provides a comprehensive summary of the research progress on starch from various tropical crops. Specifically, the extraction technology, amylopectin content, multiscale structure, physical and chemical properties, processing technology, and applications of starch are reviewed. The advancements, application prospects, and research suggestions on starch from characteristic tropical crops are also discussed, which provides theoretical guidance for enhancing the processing level of related products and diversifying food sources.

“…The mechanical methods include ultrasonication, high-pressure homogenization, and oscillatory bead impact fragmentation, while the non-mechanical methods include enzymatic digestion, chemical fragmentation, and freeze–thaw fragmentation. Ultrasound-assisted enzyme extraction (UAEE) is used in many fields, including the extraction of polysaccharides [ 20 , 21 ] and resistant starch [ 22 ], as well as the preparation of peptides [ 23 ].…”

Tea saponins have high surface-active and biological activities and are widely used in chemicals, food, pharmaceuticals, and pesticides. Tea saponins are usually extracted using ethanol or water, but both methods have their disadvantages, including a negative impact on the environment, high energy consumption, and low purity. In this study, we explored an effective process for extracting tea saponins from tea meal using deep eutectic solvents combined with ultrasonic extraction and enzymatic techniques. The experimental results showed that a high extraction efficiency of 20.93 ± 0.48% could be achieved in 20 min using an ultrasonic power of 40% and a binary DES consisting of betaine and ethylene glycol (with a molar ratio of 1:3) at a material–liquid ratio of 1:35 and that the purity of the tea saponins after purification by a large-pore adsorption resin reached 95.94%, which was higher than that of commercially available standard tea saponin samples. In addition, the extracted tea saponins were evaluated for their antioxidant and bacteriostatic activities using chemical and biological methods; the results showed that the tea saponins extracted using these methods possessed antioxidant properties and displayed significant antibacterial activity. Therefore, the present study developed a method for using deep eutectic solvents as an environmentally friendly technological solution for obtaining high-purity tea saponins from tea meal oil. This is expected to replace the current organic solvent and water extraction process and has great potential for industrial development and a number of possible applications.

“…Wang et al [ 20 ] developed and optimized a new method for ultrasound-assisted enzyme extraction of kiwi starch using RSM. Kaur et al [ 21 ] prepared RS from green banana peels with the ultrasound-assisted enzymatic extraction. The effects of process parameters such as treatment time, temperature and liquid-to-solid ratio on the yield of RS were investigated using RSM and the Box–Behnken design.…”

Corn starch was dually modified using thermostable α-amylase and pullulanase to prepare resistant starch (RS). The concentration of starch liquid, the amount of added thermostable α-amylase, the duration of enzymatic hydrolysis and the amount of added pullulanase were optimized using RSM to increase RS content of the treated sample. The optimum pretreatment conditions were 15% starch liquid, 3 U/g thermostable α-amylase, 35 min of enzymatic hydrolysis and 8 U/g pullulanase. The maximum RS content of 10.75% was obtained, and this value was significantly higher than that of native corn starch. The degree of polymerization (DP) of the enzyme-modified starch decreased compared with that of native starch. The scanning electron microscopy (SEM) and differential scanning calorimetry (DSC) were performed to assess structural changes in native and pretreated starch. The effect of dual enzyme pretreatment on the structure and properties of corn starch was significant. Unlike the untreated one, the pretreated corn starch showed clear pores and cracks. Significant differences in RS contents and structural characterization between starch pretreated and untreated with dual enzymes demonstrated that the dual enzyme modification of corn was effective in enhancing RS contents.
