Comparative Studies on the Effect of Boiling and Fermentation on Calabash Gourd Melon (Lagenaria siceraria) Seeds

Abstract

The research was carried out to collect some useful information on Lagenaria siceraria (Calabash gourd melon) seeds. The dried melon seeds were sorted, cleaned, soaked in water for easy removal and dehulled by abrasion to get the cotyledons, which were divided into three parts. The first part was used directly for analysis, the second part was boiled while the third part was fermented and analysed. Boiled melon had the highest fat and protein content while the raw melon had the highest carbohydrate content, however there was no significant increase in the ash content of the samples. There was a significant reduction in the antinutritional factors of boiled and fermented melon samples compared to the raw melon. Processing led to significant increase in the antioxidant activities and vitamin contents. The study observed that processing led to significant increase in the nutritional composition of the melon seeds and significant reduction in the antinutritional factors.

“…The crucible was taken out of the furnace, re-weighed and placed in a desiccator for further use. The percentage ash content was calculated using Equation (2) [11] .…”

Phytochemical composition of Lagenaria siceraria fruits from KwaZulu-Natal and Limpopo, South Africa

“…Tender fruits remedy asthmatic and other bronchial disorders and they contain phytochemicals such as terpenoids, saponins, flavonoids, polyphenolics, tannins, cucurbitacin; B, D, G, H and 22-deoxy cucurbitacin, which are responsible for the bitterness in cucurbits ( Ahmed, Ejaz, Saeed, & Dar, 2016 ; Roopan, Rajeswari, Kalpana, & Elango, 2016 ). The sterols; fucosterol and campesterol are also found in the fruit pulp along with flavone-C glycosidase as well as lagenin, a ribosome-inactivating protein with antiproliferative, antifertility, anti-HIV and anti-cancerous activities ( Ahmed et al, 2016 ; Lleola, Omodaru, & Filua, 2019 ; Wang, Cao, Hao, & Wu, 2022 ). In addition, L. siceraria seeds are also high in phytochemicals, vitamins, mineral elements, amino acids, and lipids identifying them as a source of protein, micro and macronutrients ( El-Rahman, Mahmoud, Sayed, & El-Latif, 2022 ).…”
