Fluted pumpkin (Telfairia occidentalis) seed is a perennial plant that belongs to the family of Cucurbitaceae. Several nutritional values of the seeds have been reported. In this present study, thirty rats (average weight= 133 g ± 1.25 g) were randomly allocated to 5 groups of 6 rats each and placed on a conventional diet supplemented with groundnut meal (control), unprocessed fluted pumpkin seed flour (UF_Diet), boiled fluted pumpkin seed flour (BF_Diet), germinated fluted pumpkin seed flour (GF_Diet), and soaked fluted pumpkin feed flour (SF_Diet) for 28 days after which animals were sacrificed and blood samples collected for biochemical and haematological analysis. Results revealed that processing improved the protein content of the seed flours. The aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP) range from 210.70±2.14 to 517.5±5.39 U/L, 60.6±0.30 to 386.3±3.53 U/L, and 221.7±1.21 to 328.4±3.31 U/L respectively. Processing significantly decreased (p< 0.05) the creatinine content of rats fed supplemented fluted pumpkin seed flours when compare with the control and unprocessed groups. The hematological parameters were also significantly (p<0.05) improved by the dietary treatments. The result of this study revealed that germination, soaking, and boiling were effective processing methods for improving the nutritive values of fluted pumpkin seed meals

Discovery of a mutant thin-coated seed phenotype at the end of the 19th century facilitated pumpkin (Cucurbita pepo L.) seed oil production and increased botanic interest in seed coat types and their structures. The main seed coat characteristics were usually analyzed by light and fluorescent microscopy, and more recently, seed coat traits have also been mapped on a C. pepo gene map. The aim of our research was to collect and describe various pumpkin seed types and to analyze, using scanning electron microscopy (SEM), the detailed structure of their seed coats. Seeds of 29 cultivars and landraces were collected and visually evaluated based on seed coat characteristics. Seed samples belonging to different seed types discovered in our collection were transversely sectioned and analyzed by SEM. Twelve seed types were determined, and SEM analysis revealed high variability in their seed coat structures. Using SEM, tissue and cell structures were clearly visible, and novel details of cell and tissue topography were documented. Hypodermal and aerenchyma cells in wild-type seed coats showed fibrous or reticulate secondary cell wall thickening, respectively. In mutant seed types, an absence of different seed coat layers was clearly noted, while the remaining layers were distinctly pronounced. A new completely hull-less seed type was described for the first time. Description of the variability of seed coats in pumpkin was complemented by novel seed coat types, and their structures were analyzed in detail the first time by SEM.

Supplement in mushroom production boosts yield. Fluted pumpkin parts were assessed as an alternative to wheat bran as supplement in mushroom production. Sawdust, lime and wheat bran or fluted pumpkin (Pod, seed, stem) were mixed in ratio 180: 1: 30. There were 10 replicates for each treatment. The design was completely randomized blocked design. The results showed that supplemented sawdust with wheat bran had higher value for the dry weight with significant difference from treatments with pumpkin parts in some flushes and none in other flushes Supplemented sawdust with mixture of all supplements was highest in Ash (14.30%) and moisture (24.75%). Protein and lipids values were highest for supplemented sawdust with wheat bran and significantly different (p<0.05) from other treatments. Sawdust supplemented with fluted pumpkin stem (28.06%) had highest value for carbohydrates while that supplemented with pod had (21.16%), the highest for fiber. For minerals, K (794.50 mg/kg), Ca (349.75 mg/kg), and Na (379.50 mg/kg) were highest for Fluted Pumpkin Seed Supplement, Fluted Pumpkin Pod Supplement and No Supplement respectively. In conclusion, Fluted pumpkin pod and stem compares very well with wheat bran supplement, and can serve as supplement in the production of oyster mushroom.

Column Adsorption

The use of waste to reduce pollution has been advocated by many researchers. In this study five samples of physically prepared fluted pumpkin seed shell activated carbons (PFACs) prepared elsewhere were successfully used in reducing Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) of vegetable oil industry effluents (VOIE). BOD readings of effluent were measured using the Lovibon BOD IR Sensomat while COD was determined by use of PCcheckit COD Vario (Lovibond) consisting of PCcheckit COD Vario photometer and COD reactor ET 108 model. Batch adsorption had better performance (BOD and COD removal of 52 % to 83 %) over column adsorption (BOD5 and COD removal of 35 % to 86 %). Batch adsorption gave better BOD and COD reduction. Though BOD and COD removal varied widely with carbon dose, pH, temperature and contact time the effects of theses factors investigated in the reduction of BOD and COD were complex and difficult to streamlined.
