EFFECT OF LOCAL PACKAGING ON QUALITY OF FRESH
PRODUCE (TOMATO)
CHAPTER ONE
INTRODUCTION
1.1 Background of the study
Tomato
(Lycopersicon esculenta) is an important fruit vegetable consumed all over the
world. The consumption of tomato in recent time has increased due to the
associated benefits of some phytochemicals including carotenoids. Carotenoids
are responsible for the colour in tomatoes which are synthesized massively
during fruit ripening [1]. Other notable component of tomatoes is vitamin C.
Depending on variety and growing conditions, the vitamin C content of tomatoes
may vary between 39-263 mg/100 g [1]. For instance, tomatoes grown on organic
substrates were found to contain significantly more Ca and vitamin C than
tomatoes grown on hydroponic media [2]. Tomatoes may be eaten either raw or
cooked. Being a climacteric and perishable vegetable, tomatoes have a very
short lifespan, usually 2-3 weeks [3]. Hence, tomato fruits must be properly
handled after harvest in order to maintain quality and enhance consumer appeal
during sale. The quality of tomato is determined by appearance, firmness,
flavour and the nutritive value. These quality parameters are affected by
several factors including, variety, agronomic practices, method of harvesting,
time of harvesting, postharvest handling techniques, packaging materials and
storage conditions. Packaging generally
helps to protect
and retain the quality of fresh
horticultural produce and reduces damage during
papers, which
showed approximately 20% weight loss after 28 days of storage at ambient
temperature of 32 ± 2oC [6]. Commercially, different packaging materials are
used in the wholesale and retail market for the sale of fresh produce such as
tomatoes. As stated above, the properties of these packaging materials may
influence the product quality. Hence, this study investigates the influence of
retail packaging; open box, open market bag, Xtend bags and sealed box on the
quality of freshly harvested tomato fruits.
1.2 Statement of the problem
There have been
the challenge of the effect of local packaging on the quality of fresh produce.
This work gives recommendations.
1.3 Objectives of the study
1. To understand
the effect of local packaging on quality of fresh produce
2. To understand
the challenges of local packaging and solutions to improve upon it
1.4 Research questions
1. What is the
effect of local packaging on quality of fresh produce?
2. What are the
challenges of local packaging and solutions to improve upon it?
1.5 Research hypothesis
H0: There is no
relationship between local packaging and quality of fresh produce
H1: There is a
relationship between local packaging and quality of fresh produce
