“…The pumpkin fruits (Cucurbitapepo) belongs to the Cucurbitaceae family. It is classified as functional food due to its rich content of bioactive compounds, minerals, and antioxidants in the fruit pulp, making pumpkin a (Buzigi et al, 2020;Priori et al, 2022). It contains low calories, with a good amount of fibers and vitamin C (Amin et al, 2019).…”

This study was to investigate the effects of combination of calcium carbonate with irradiation technique on quality characteristics, nutritional values, bioactive components, microbiological loading, and sensory evaluation of pumpkin jam during storage period for 12 months. Pumpkin jam samples were treated with calcium carbonate 1% (CCS), irradiation (2 kGy) and the combination of CCS + 2 kGy. The results indicated that the CCS + 2 kGy treatment significantly helped in retaining ascorbic acid content, which established a little decrease. CCS and CCS + 2 kGy treatments reported similar values for carotenoid contents. Whereas, CCS + 2 kGy treatment showed the highest total flavonoid content. The application of CCS + 2 kGy treatment also reduced the microbial growth for total aerobic plate, yeast and mold counts. The degree of color was higher recorded for CCS treatment, while CCS + 2 kGy treatment gained the highest scores for texture, flavor, taste, and overall acceptability at the end of the storage period. Overall the results pertained that the use of Gamma irradiation combined with calcium carbonate prolonged the shelf life of the pumpkin jam by reduced the microbial load, maintained the quality characterizes, nutritional values, bioactive components, and consumer acceptability of pumpkin jam during storage.

The historical meeting between originally American people, European colonizers, and slaved peoples from Africa in the biome Pampa in South Brazil and Uruguay involved a cultural syncretism and a great genetic diversity of landraces of cultivated species. Genetic richness evolved by selection and cultural processes in response to different environments, cultural backgrounds, and needs. This review summarized the knowledge on vegetable and maize landraces in South Brazilian and Uruguayan Pampa biome, to design a strategy towards the rediscovery, conservation, and sustainable use. Landraces diversity maintained in situ and ex situ is described, specific case studies are presented, and the main problems and tools towards landraces re-valorization are discussed. We show that traditional family farming systems maintain diverse vegetable species, mainly squashes (Cucurbita spp.), sweet potato (Ipomoea batatas), beans (Phaseolus spp.), onion (Allium cepa), peppers (Capsicum spp.), tomato (Solanum lycopersicum), next to leafy vegetables and maize, among others. We propose the priority of systematic surveys as a basis for monitoring genetic erosion, increasing complementariness between in situ and ex situ conservation, and implementing sustainable conservation and utilization. The case studies highlight genetic diversity within each cultivated species, with different crop physiological responses; disease resistances, different quality traits and associated uses, from animal feeding in maize to a range of culinary uses linked to traditional culture in maize and vegetable species, and ornamental uses of specific Capsicum and Cucurbita. Some landraces were the basis for breeding, where improved cultivars allowed the competitiveness of landrace germplasm in the markets. Renewed industrialized products allowed the competitive and sustainable use of Capsicum landraces in Brazilian farmers communities. Strategies towards in situ conservation improvements and valorization are discussed; emphasizing the role played by agroecology, community seed banks and custodian farmers, participatory plant breeding, promotion of landraces specialties among consumers, and the need of research and capacity building, among others. Farmers’ participation in the decisions is a key factor, along with the academia and the public sector. Landraces and associated knowledge are treasures to be used to benefit from farmers to consumers, directing the course of agriculture towards sustainable directions.
