Usually small traders or middle men move around the villages to download the groundnuts. More often they are exploitative because they offer low prices but they offer a ready market for the smallholder farmers as they download at the farm gate and help the smallholder farmer save on transport to the market.

Usually farmers sell individually to the vendors and have a weak bargaining power compared to selling in a group. For example after harvesting, groundnuts are cleaned to remove foreign materials and graded according to different sizes.

At this point some of the groundnuts is packed and sold. Other companies go beyond the packing stage to process the groundnuts further into roasted nuts, peanut butter, paste, oil and animal feed groundnut cake. Over the years, the market for groundnut cake has declined due to high levels of aflatoxin in the groundnuts which affect downloaders interest to download.

The majority of processors are also exporters of various products of groundnuts to regional and global markets.

Travelling to Italy

From figure 1 above, it can be shown that the export of groundnuts increased during and The chain players have been categorized into input suppliers, smallholder farmers, downloaders and processers, 2. These companies subcontract individual farmers and companies to multiply their groundnut seed. Even though there are a number of seed companies, availability of quality seed to the rural farmers is still a challenge. Agro-dealers Over the past six years, there has been an increased growth in numbers of agro-dealers in the country.

However the biggest challenge is that most agrodealers prefer operating in areas with easy access and good road infrastructure network leaving out the remotest areas of the country.

Some of the Agro Delears have a network of satellite depots scattered in many parts of the country. As already alluded to, the remotest parts of the country are poorly served by the agro-dealers.

The network of agro dealers has helped to standardize the input prices and farmers have a wide choice of which agrodealer to get their inputs.

Membership is not free, all members have to pay a membership fees.

The association produces or multiplies groundnut seed on contract for seed companies. The input suppliers have the infrastructure such as warehousing, processing, transport; training facilities, human resources sells personnel and financial resources to enable them carry out the seed supply and distribution activities of the value chain.

Smallholder farmers either operate in groups or individuals. Over the past years CSO and some companies have helped to organize the farmers into groups to ease service delivery and strengthen bargaining power of the farmers. Organizations like One Village One Product OVOP are promoting value addition at community level and are therefore encouraging farmers to process their groundnut into oil.

Groundnut production in Malawi

Because farmers are usually not organized, their participation in the value chain is limited. There are some efforts by organizations such as NASFAM who have facilitated and mobilized smallholder farmers into sustainable groups and associations and these association sales their groundnut to big traders.

They always go to the farmers early mostly at the time when the farmers have just harvested their crops and want quick cash. They download both shelled and unshelled groundnuts. They are usually the first customers of the smallholder farmers who download and sell to assemblers at slightly higher prices than what they pay to the smallholder farmer. Some big downloader subcontract these small traders or vendor to download the groundnuts for them.

They usually have small capitals and cannot download in large quantities but they are always having the market information which they use to cheat the smallholder farmers. The group is not organized and they usually operate as individuals. They usually have high levels of market information which they use to their benefit at the expense of the farmers who have limited knowledge of where to sell their groundnut and at what price.

More often they are the ones that set the price for the vendors. In order to maximize their gains the vendors deflate the prices in order to make profit. The intermediate downloaders interest is to make profit with minimal costs. They download relatively larger quantities of groundnuts than the vendors. The group has limited interest on the farmers future capacity to produce the next crop of groundnuts. The majority of them have the capacity to download the groundnuts from the traders, value add and export.

These processors and exporters, expect to procure big quantities of good quality groundnuts from farmers which most of times are failing due to low production. If there were more organized smallholder farmer groups, selling directly to the processors and exporters would be more lucrative because the prices are usually higher than selling to vendors. One farmer said, If we can be selling to processors and exporters directly, we will be assured of the ready market and good prices for our groundnuts.

The processors are interested in adding value to the groundnuts where the groundnuts is shelled, sieved and graded and made into various products 12 such as peanut butter, salted nuts, paste, oil, seed cake for animal feed and other products.

The high levels of aflatoxin in groundnut are affecting the production of oil and other products. Most of these processors export their value added groundnuts to countries in and outside Africa. The confectioneries, including peanut butter and nuts are available in retail supermarkets and other grocery stores all over Malawi.

However, some of the shelled groundnut is exported to regional markets, including South Africa, Tanzania and Kenya Makoka, These organizations conduct research, training of students and outreach services to farmers. National research institutions such as Department of Agriculture Research Services have the mandate to coordinate research activities at national level and also coordinate with the various international and national research organizations on groundnut research, groundnut seed breeding and multiplication.

The research institutions and academia are interested in improving both production and productivity through research and training. They are also involved in conducting and setting the policy research and training agenda and quality improvement of the groundnuts in the country. The key interests include ensuring that the smallholder farmers are effectively participating in the groundnut value chain; and to improve their livelihoods by diversifying their crops, increase their household income base, mitigate the impact of climate change.

These authors also found no change in the chemical constitution of the ozonized grains, and there were no alterations in the content of amino acids and lipids. The variable electrical conductivity is directly related to the cell membrane integrity, and to the physiological quality of the grains; poorly structured membranes and damaged cells are associated to the process of deterioration Heslehurst, The peanut grains which were exposed to the ozone gas at concentrations of 13 and 21 mg L -1 , for up to 96 h, were not affected physiologically.

Similar results concerning the physiological quality of the grains were obtained by Santos for maize exposed to ozone gas at concentration of ppm, for min.

Instead, Rozado et al. Changes in hue angle and color difference, regarding the grain that were exposed to oxygen and to ozone gas at concentrations of 13 and 21 mg L -1 , at different periods of exposure are shown in Figures 2 and 3 , respectively.

The adjusted regression equations and their respective coefficients of determination relative to the hue angle and to the difference in color of peanuts that were exposed to oxygen and to ozone gas, at concentrations of 13 and 21 mg L -1 , in different periods of exposure, are presented in Tables 1 and 2 , respectively.

The change in the color of peanuts grains can be explained by the depigmentation of its skin, of reddish color, by the ozone gas. The depigmentation observed in the peanut skin can be attributed to the high oxidation potential of the ozone gas, which is equivalent to 2.

It is important to notice that the ozone gas is able to degrade various organic compounds in foods, for instance the carotenoids and the anthocyanins Mustafa, ; Henry et al.

What stands out, however, is that the change observed in the color of the skin that wraps the grains is not decisive in terms of quality, since one of the techniques adopted to add value to the product is peeling or bleaching. This technique is defined by Brasil as the procedure that consists on the removal of the skin which surrounds the peanut, through thermal and mechanical processes, to attend the consumer market or to reduce the levels of contamination and defects.

Quality of the crude oil extracted from ozonized peanut grains. The percentage of free fatty acids from crude oil remained within the range of 0. The average values of free fatty acids from crude oil extracted from the grains, which had been exposed or not to ozone gas, remained below the limits required by ANVISA for selling crude peanut oil, which is 2.

It is possible to notice that the average values of the peroxide index remained below the 10 meq kg -1 sample, which is the limit that has been established in Brazil for selling crude peanut oil ANVISA, Similar results were obtained by Faroni et al. There was also no significant variation due to factors related to either ozone gas concentration, or exposure time, when analyzed separately.

The mean iodine value was According to the Brazilian laws, the iodine index of crude peanut oil should remain within the range of 80 and g I 2 g -1 of sample ANVISA, These results confirm the studies of Mendez et al.

The analysis and interpretation of the data showed that despite the high oxidizing power of the ozone gas and its ability regarding the depigmentation of the skin of the peanuts, the quality of the grains, and the quality of the crude peanut oil are not affected by the ozone, at concentrations of up to 21 mg L -1 , and at exposure periods of up to 96 h.
