“…The increase in lycopene during drying confirms the findings of [24], who reported that thermal treatment could increase the release of phytochemicals from the matrix of the tomato, as well as [25] who reported increase in lycopene of hot air-dried tomato. The increase in lycopene content in all dried samples could be due to break down of cell walls by thermal process, which weakens the bonding matrix between lycopene and tissue matrix and hence, make lycopene more accessible [26].…”

Tomato (Lycopersicon esculentum) is regarded as one of the most important vegetable crops grown all over the world and Nigeria in particular, after onions and pepper [1]. In Nigeria, tomato accounts for about 18% of the average daily consumption of vegetables [2].Tomatoes are a good source of vitamin C and vitamin A equivalents (in the form of β-carotene) and provide some vitamin E, folic acid, potassium and other trace elements. One of the most well-known tomatoes eating benefits is its lycopene content. Lycopene is a vital anti-oxidant that helps in the fight against cancerous cell formation as well as other kinds of health complications and diseases. Diets that include tomato have been linked with reduced risk of obesity and some neurological diseases including Alzheimer's disease.Nigeria is ranked the second largest producer of tomato in Africa and 13 th in the world [3]. Due to lack of post-harvest enterprise and poor post-harvest storage plans, Nigeria is unable to meet its domestic demands for tomatoes even though it ranks 13 th on the world tomato production hierarchy. The high moisture content of tomato makes their handling, transportation and marketing a problem especially in the tropics [4]. Tomatoes deteriorate rapidly after harvest, requiring preservation and/or processing in other to extend its shelf life.Drying tomatoes is one of the easiest known preservation methods. The amount of time it takes to dry tomatoes depends on the tomato variety, the air's humidity during the drying process, the thickness of the tomato slices or pieces, and the efficiency of the dehydrator or oven. Traditionally, drying has been used as a method of preserving foodstuffs in Nigeria and other developing countries [5]. Drying basically removes moisture from food and this inhibits the growth of bacteria and fungi. Moreover, it slows down the enzyme action without deactivating them. These factors ensure that food does not spoil easily and hence, makes drying an effective food preservation technique.Since tomato is seasonal, preservation is important to minimize wastage and spoilage during the tomato producing season and to ensure that maximum nutritional contents of the fruits are retained. The success of such effort would lead to the development

Tomato fruits have high nutritional qualities, but their spoilage by soil-borne pathogens results in food poisoning. It is important to isolate and identify the strains of fungi associated with tomato rot, to understand their pathogenic state. Seeds of 3 genotypes of tomato were grown in both hydroponics and soil systems. It is a factorial experiment laid in a completely Randomized Design with four replicates. The number and weight of fruits produced, number of infected and uninfected fruits by rots were recorded. Data collected were analyzed using ANOVA and means were separated using LSD at 5 % significance level. At harvest, the infected and uninfected fruits were harvested and 10 g each were sliced, dissolved in sterile distilled water and were serially diluted before plating on sterile Potato Dextrose Agar-PDA and Sabouraud Dextrose Agar-SDA media with 2 % streptomycin and incubated at 28 o C for 3 -7 days. Genotypes and substrates were significant in the rate of fruit infection, with the Roma tomato having 78.1 % fruit infection rate, while the identified fungi from the infected tomato fruits are Aspergillus flavus and Mucor racemosu, as no organism grew in the uninfected fruits cultured in both PDA and SDA culture media.

“…However, despite all the challenges still there is the need to preserve the vegetables to make it available year round there by reducing global food epidemics. Also results of the previous studies by Alao (2000) has showed that for a country to achieve self-sufficiency in food, there is the need to put in place all strategies for increasing crop production (Mustapha and Yahaya, 2006 ;Kutama et al 2007). The method of washing pepper is highly important in reduction of contamination after harvest by washing away the surface pathogens which might cause spoilage thereby reducing the post-harvest losses of the commodity (Babalola et al 2010;Hernandez-Brenes, 2002a).…”

Sample of pepper was collected from two selected vegetable markets and used to determine the most effective method of increasing shelf life of pepper. In the research two treatment methods used by marketers of vegetables washing with water and detergent were compared. The results showed that five fungal colonies were isolated from pepper samples obtained from the study aeas. The five fungal colonies isolated from the two markets have the following frequency of occurrence A. niger 17 ( 28.3 %) A. fumigatus 12 (23.3%), R. stolonifer 12 (20.0%), A. flavus 09(15.05%) and Mucor spp 08 (13.3%). Out of the total 60 fungal colonies isolated in the two markets, more colonies were counted from water wash pepper 37 ( 61.0%), while lower colony counts were recorded from detergent washed pepper in the two locations 23 ( 38.3%). It is clear therefore that, this investigation has established fewer fungal colonies counted from detergent washed samples in the two markets is that washing of pepper with detergent is more effective in increasing the shelf life of pepper by removing the surface contaminant micro-organisms.
