EFFECT OF DIFFERENT PACKAGING MATERIALS ON THE QUALITY OF AFRICAN OIL BEAN SEED  (PENTACLETHRA MACROPHYLLA BENTH)
ABSTRACT
Effect of packaging materials for the preservation of the ‘Ugba’ as studied and evaluated. Raw African oil bean seed was processed to ‘ugba’ by fermentation for 72hours.  Wrapped in plant in leaf (musaparadisiaca). Proximate analysis was carried out on the freshly produced ugba which has undergone fermentation for 72hr.  The fermentation ‘ugba’ was then dried for 72hrs and packaged using 3 different packaging materials. (Leaf, plastic and tin) and stored for 14days respectively.  On the 7day, and 14days of storage, proximate analysis, microbial (TV and Mould) and sensory evaluation of the stored ugba was carried out. The statistical analysis was determined using 2x2 factories experiment in Randomized complete block design (RCBD) least significant different at P<0.05.  The composition of the ‘ugba; after the 2 weeks of storage ranged from (10.84%-34.32%, 5.94%-34-32% and 6.98%-34.32%) for DUPL, DUPP and DUPT respectively. Protein ranged from (16.45%-17.32%, 16.45%-18.10%, and 16.45%-17.86%); fibre ranged from (14.11%-14.59%, 14/59%-16.62%and 14.59%-15.88%); fat ranged from (10.00%-13.06%, 12.86%-13.64% and 12.30% -13.86%); ash content ranged from (1.48%-6.12%,1.94%-6.12% and 2.34%-6.12%), and CHO ranged from (6.03%-19.60%,6.03% and 2.34%-6.12%), and CHO ranged from (6.03%-19.60%, 6.03% and 217.86% and 6.03% -16.66%) for DUPL, DUPP and DUPT respectively.  There were significant differences (P<0.05) among all the sample in protein, CHO, fat, fibre, moisture and Ash).  DUPT (dried ugba packaged in tin) has the highest effect in all the stored sample then followed by that of  DUPP (dried ugba packaged in plastic) and the least was DUPL (dried ugba packaged in leaf).  Microbial analyses was carried out after the day 14 of the storage and ranged from (3.6 x 105 -5x5 x 109 (cfu/g) for DUPL, DUPP and DUPT respectively.  The analysis carried out showed that ugba can be preserved by drying and packaged using tin as the major packaging material.

CHAPTER ONE
1.1    BACKGROUND OF THE STUDY
Ugba is the Igbo name for sliced fermented African oil bean seed (pentalethra Macrophylla benth). The African oil bean seed called several names in Nigeria, such as ‘Apara’ by Yoruba, ‘Ugba’ or ‘Ukpaka’ by the Igbos (Enujiugha and Akanbi, 2005). It is consumed mostly in the eastern states of Nigeria as a local delicacy popularly known as ‘African salad’ prepared with oil, pepper, fish, salt and its also prepared tapioca, stock-fish and garden eggs. It can be eaten with boiled or roasted yam and cocoyam (Okafor et al., 1991; Mbajunwed et al., 1998). Ugba is a traditional food generally prepared in homes in a small family business. Its method of preparation varies from house or one place to another resulting in non-uniform product (Njoku and Okemadu, 1999). ‘Ugba’ is produced traditionally by boiling the seeds over night for easy removal of the seed coat. The cotyledon are sliced and cooked until they are soft with reduced bitter taste. The sliced ‘Ugba’ is washed about 5 times or more and fermented for 3days (Eunjiugha, 2003)
According to Enujiugha, (2003), the cooked, processed and fermented seed ‘Ugba is used to prepare some delicious African soup and sausage for eating different staples. Enujiugha (2003) also noted that it is a rich demand for local and export consumption. Previous research showed that fermentation gives a bitter nutritional product that the raw seed (Achinewhu, 1986; Enujiugha and Olagundoye, 2001). Fermentation of African oil bean seeds to produce ‘Ugba’ softens the cotyledon, improves it digestibility and nutrients availability (Enujiugha and Akambi, 2002). Obeta (1983) showed that ‘Ugba is cheap and important source of protein especially for people whose staple food are deficient of protein in developing countries of the world. The consumption of ‘Ugba’ could pose as a means of addressing the preventing protein energy malnutrition (PEM) in developing countries (Enujiugha and Akanbi, 2008). It is cheap and available source of plant protein in developing countries of the world. Its protein contains 20 amino acids and 80% of its fatty acid are also essential (Enujiugha and Agbede, 2000, Kediobi, 1981). Ugba is a low acid food and product of alkaline fermentation (Enujiugha and Akanbi, 2005).
In many eastern communities in Nigeria, Ugba is consumed as a meat analogue due to its high protein content, the locally prepared Ugba is done through a mixed wild bacteria fermentation of the sliced, boiled and soaked African oil bean seeds (Enujiugha and Akanbi, 2005, Onwuliri et al, 20 04). Thermal treatment of the seeds increases the nutrient bioavailability and the digestibility drastically reduces iron, calcium, potassium, thiamine and riboflavin levels (Enujiugha and Ayodele-oni 2003). The source of micro-organism in fermenting seeds comes from handling, processing, utensils, used in processing and packaging materials (Obeta, 1983, Odunfa and Oyeyiol, 1985).
1.1.2 PACKAGING
Packaging is an important part of all food processing operations and with some example canning, it is integral to its protective role as in ‘packaging is a means of achieving safe delivery of products in some condition to final user at a minimum cost or it can be defined in business terms as a techno-economic function for optimising the cost of delivering goods whilst maximising sales and profits.
Functions of packaging are:
  containment: to hold the contents and keep them secure until the y are used
   Protection: against mechanical and environmental hazards encountered during distribution and use
 Communication: to identify the contents and assist in selling the products.
 Machinability: to have good performance on production lines for high speed filling, closing and collecting (1000 packs per min or more), without too many stoppages.
    Convenience: throughout the production, storage and distribution system including easy opening, dispersing and/or after use retail containers for consumers (Paine 1991)
1.2    STATEMENT OF THE PROBLEM
The growing profile of ‘Ugba’ African oil bean seed has made it an important snack food among the low and middle income earners. The increased acceptance and consumption of ‘Ugba’ has led to its high demand. However, due to its long fermentation time of about 3-4days (72-94hours) for an unreasonable quantity  and its short shelf-life, ‘Ugba’ (African oil bean seed ) processors have encountered daunting tasks in keeping up to the demand and maximizing gain as a result of loss of quality to its continued fermentation, even day after the desired texture has been attained.
The lack of uniformly in texture of fermented Ugba is also a major worry. Nevertheless, good packaging and storage techniques that can impact improvement in keeping quality and digestibility are very essential in ensuring the elongation of its shelf-life and maintaining it quality.
1.3    JUSTIFICATION
There is high demand for African oil bean seed as a result of its high nutritional content. It serves as a source of protein especially for people whose staple food is deficient. The major problem or challenges is Ugba production is the keeping quality ‘Ugba’ does not stay for a long time considering the fact that it is been wrapped with leaf traditionally as this poses to deterioration faster.
1.4    OBJECTIVE OF THE STUDY
The aim of this study is to evaluate the effect of packaging materials on the keeping quality of ‘Ugba’
