“…The estimated daily intake (EDI) is directly linked to the metal concentration, food consumption, and body weight. The following assumptions were made in this research to estimate the risk of heavy metals from egusi consumption at the extreme; the ingested dose was equal to the absorbed pollutant dose [ 15 ]; cooking did not affect the pollutants [ 16 ]; the average Ghanaians adult body weight was 75 kg [ 17 ]; the average daily consumption of egusi in Ghana is 30 g per day (average daily consumption in Nigeria according to [ 18 ]). People who obtain egusi from the Madina market will consume the same as Agbo , Nima , and Dome markets.…”

The present study was undertaken to investigate the physicochemical and microbiological qualities of melon seed powder sold in some open Ghanaian markets. Twenty-five samples of powder were collected randomly from each of four major markets and analyzed for moisture, pH, total ash, acid insoluble ash, and free fatty acids (FFA) using standard methods. The microbial population was determined using the pour plate method. Melon seed powder samples had a neutral pH (6.9-7.3) and contained significant amounts of ash (0.1-0.6%). Acid insoluble ash of powder from one market was high (0.6%) and possibly indicate contamination with siliceous earth material. FFA ranged between 4.1 and 11.6% for powder from the four markets. Levels of lead were higher (0.4-0.8 ppm) than other metals such as cadmium (0.02 ppm) and copper (0.3-0.6 ppm). HQ values >1 were recorded for Pb, implying a greater risk of toxicity to consumers. Counts for aerobic bacteria, fecal coliforms, and yeast and molds were in the range of 3.2-4.4, 1.6-4.0, 1.4-2.8, and 1.1-3.2 log CFU/g correspondingly for these organisms. E. coli was not detected in any of the melon seed powder samples analyzed. This study highlights the need for proper handling of melon seed during processing, storage, and distribution, to safeguard its quality for consumers.

“…It is grown virtually everywhere; tropical, sub-tropical, and temperate regions. Melon is consumed in many parts of Nigeria, but despite its nutritional and commercial value, its production remains low (Abiola and Daniel, 2014;Adeyemo and Jacxsens, 2016). Even with its good market price, melon is still produced by farmers on a small scale.…”

“…Even with its good market price, melon is still produced by farmers on a small scale. Production of the crop is more popular in the Northern parts of Nigeria where there is an abundance of cultivable land which has made the practice of sole or mixed cropping possible (Abiola and Daniel, 2014;Adeyemo and Jacxsens, 2016;Endl et al, 2018;Ukwuaba et al, 2019). Dried melon as it is so called in Nigeria is an excellent source of polyunsaturated fatty acids (PUFA), which are essential to the body and since the body cannot manufacture them, they must be provided through the diet (Giwa et al, 2010;Endl et al, 2018).…”

The study was carried out to examine the socioeconomic and performance of the dried melon value chain in Owo Local Government Area of Ondo State, Nigeria. The data for the study were collected primarily using a well-structured questionnaire. A two-stage sampling procedure was used to randomly select 120 respondents. Descriptive statistics, budgetary techniques, and multiple regression models were used to analyse the data. The results of the socioeconomic characteristics revealed that male dominates the producers’ chain while female dominates the processors’ and marketers' chains. All the actors were still in their economic active age with a mean age of around 40 years old. Many of the actors were married and had good years of experience with the producers being the highest (18 years). Apart from the producers, many of the actors were educated with at least a primary school education. Processors made more income (N190,374.7) than the producers (N175,709.3) and the marketers (N132,374.4). Despite that, the budgetary techniques confirmed that each chain was profitable, the return on investment was at the highest (0.59) for the processors followed by the producers (0.44) and then, the marketers (0.40). The market margin results showed 0.31, 0.37, and 0.29 for the processors, producers, and marketers, respectively. The results of the multiple regression indicated that costs of labour, transportation, and fixed input significantly influenced producers’ volume of sales. The variables like education, unit price, and labour cost significantly influenced processors’ volume of sales, while age, sex, income, experience, and unit price significantly influenced the marketers’ volume of sales. Therefore, it can be recommended that government intervention is crucial in the melon value chain by subsidizing the inputs to reduce the cost of production and processing. The government should also provide credit facilities and other infrastructure, such as roads, which will reduce the high cost of transportation.
