“…XT tubers contained the most moisture (10.06％) , while BS tubers contained the lowest value (4.57％) . This can be explained by the different contents of soluble sugars due to their hydrophilic properties, which affect the water holding capacity of the tigernut tuber matrix during the drying procedure 25) . Oil contents in the six samples differed significantly (p＜0.05) within the range of 19.06％-30.12％.…”

IntroductionTigernut (Cyperus esculentus L.) is grown for its tubers, which accumulate large amounts of oil 1) . It is widely planted in temperate, subtropical, and tropical regions such as China, France, and the Congo 2) . Tigernut was introduced to China in 1950, and now is cultivated in the provinces of Jilin, Hebei, Henan, and Yunnan for sustainable utilization of wasteland and mudflats 3) .Tigernut oil (TNO) , is approximately 28％ by dry weight of tigernut tubers. It is comparable to olive oil and walnut oil in containing a particularly high level of monounsaturated fatty acids (＞65％) 4) . TNO mainly consists of five fatty acids: palmitic, oleic, linoleic, stearic and n-heneicosanoic acid 5) . Tigernut starch (TS)

“…The drum-dried flours had lower monolayer moisture compared to flours produced by air oven drying or solar drying. The difference in monolayer moisture content may be attributed to heat-induced physicochemical changes that reduce the number of water binding sites during drying [39]. Another explanation may be that drum drying was more efficient in moisture removal from the flour because of the thermodynamics of this drying technique.…”

β-Carotene is an important plant pigment with high vitamin A activity. The kinetics of β-carotene degradation and moisture sorption behavior of yellow cassava flour produced by different drying techniques was investigated during storage. The β-carotene degradation kinetics were described using a first-order kinetic model, while the moisture adsorption data was fitted to five mathematical equations using nonlinear regression. During storage, the reaction rate constant for β-carotene degradation, which increased with increasing temperature, ranged from 0.0045 to 0.0396, 0.0029 to 0.0309, and 0.0025 to 0.0349 per month for flour produced by solar drying, hot air oven drying, and drum drying, respectively. Flour produced by solar drying had the highest activation energy of 124.2 kJ/mol, whereas drum drying had the lowest activation energy of 85.8 kJ/mol. All the yellow cassava flours showed a type II sigmoidal sorption curve in which the equilibrium moisture content increased with increasing water activity. The GAB model was the best for describing the moisture sorption behavior of the product, with a predicted monolayer moisture ranging from 2.8 (for drum drying) to 8.0 g water/100 g of flour (for solar drying). Findings from this study are vital for establishing the packaging and storage requirements of yellow cassava flour.
