“…The seeds of these two wild fruits were a rich of source of both lipids and protein, significantly so in C. foetidissima and C. radicans, respectively. This property was in accordance with previous reports highlighting the abundance of these nutritional components in the seeds of C. foetidissima, which were reported to have high contents of seed oil and protein and be rich in unsaturated fatty acids [16,50] and globulins [18,26,51,52], respectively, the latter of which surpassed 60% of the total seed composition [2,18,22,25,31,37]. This property was similar to that present in seeds of cultivated Cucurbita species [32][33][34][35].…”

“…However, knowledge regarding several non-forest herbaceous plant species that have the potential to be exploited for commercial use, such as Cucurbita foetidissima Kunth and C. radicans is limited [2][3][4]. Cucurbita foetidissima is part rich in starch content, may be used for human or animal nutrition [3,22]. This rich starch source has also been appraised for bio-fuel production or as a food supplement.…”

“…The information provided is also valuable in the context of the potential use of these two cucurbit species for profitable agricultural programs in arid and semi-arid regions [16,22,[31][32][33][34][35][36]. In this respect, C. radicans and C. foetidissima are considered as a vast source of genetic variability for the development of, for example, domesticated Cucurbita cultivars having increased resistance to (a)biotic stress, predominantly caused by drought, viral and fungal infection and insect infestation [37,38].…”

Cucurbita foetidissima and C. radicans are scarcely studied wild pumpkin species that grow in arid and semi-arid areas of Mexico and the United States. This study describes the morphological, proximal composition, metabolic finger-prints and seed protein profiles of C. foetidissima and C. radicans fruits collected in the wild during a one-year period in different locations of central-western Mexico. The results obtained complement the limited information concerning the fruit composition of C. foetidissima and greatly expand information in this respect regarding C. radicans. Morphology and proximal composition of their fruits varied significantly. Different metabolic fingerprints and seed protein profiles were detected between them and also with the chemical composition of domesticated Cucurbita fruits. The neutral lipids in seed, pulp and peels were rich in wax content and in unsaturated compounds, probably carotenoids and tocopherols, in addition to tri-, di- and mono-acylglycerols. The tri- and diacylglycerol profiles of their seed oils were different from commercial seed oils and between each other. They also showed unusual fatty acid compositions. Evidence of a possible alkaloid in the pulp and peel of both species was obtained in addition to several putative cucurbitacins. An abundance of phenolic acids was found in all fruit parts, whereas flavonoids were only detected in the peels. Unlike most cucurbits, globulins were not the main protein fraction in the seeds of C. radicans, whereas the non-structural carbohydrate and raffinose oligosaccharide content in their fruit parts was lower than in other wild cucurbit species. These results emphasize the significantly different chemical composition of these two marginally studied Cucurbita species, which was more discrepant in C. radicans, despite the notion regarding C. foetidissima as an aberrant species with no affinity to any other Cucurbita species.

“…The viscosity decreased with increasing shear rate; this implied that water caltrop starch paste behaved as a non-Newtonian fluid. A similar result was also found in Kunth root starch [47]. The parameters of the Herschel-Bulkley model used to describe the flow curves are presented in Table 3.…”

This study focused on the effect of cycled heat-moisture treatment (cHMT) on the in vitro digestibility, rheological, and physicochemical properties of water caltrop starch. The amylose content increased significantly by cHMT, whereas damaged starch content decreased only in the groups with more than two cycles applications. cHMT generally increased the weight-average molecular weight, except for single cycle treatment which showed the reverse result. In thermal properties, the onset temperature (T0), peak temperature (Tp), and conclusion temperature (Tc) increased, while the enthalpy needed to complete the gelatinization was lowered by cHMT. Water caltrop starch paste showed less shear-thinning behavior with cHMT. Meanwhile, the viscosity and tendency to form strong gel were enfeebled with modification. cHMT significantly changed predicted glycemic index (pGI) value, especially in samples that underwent the most cycles of treatment, which showed the lowest pGI compared to native and other treatment. These results suggested that cHMT water caltrop starch was effectively modified and showed diversified properties.
