    ABSTRACT

    Indigenous fermented foods are traditionally produced by communities through natural fermentation processes using locally available ingredients and microbial cultures. The study was carried out to explore the Prospects and Constraints of Improvement on Indigenous Fermented Foods. Investigation revealed that the traditional, artisanal methods used in the production of indigenous fermented foods often result in variations in product quality and safety. This inconsistency is primarily due to the use of natural or wild microbial cultures and the lack of controlled fermentation conditions. The problem inherent in the technology of the traditional family and ethnic method of fermenting local staples were found to result from the following limitations associated with different aspect of indigenous fermentation processes, thus a production environment, lack of knowledge of the culture of the processes, absence of any control in the processing variables like PH, temperature etc, lack of awareness of the nutrition and /or toxicological implications of fermentation and its products.

    As a result of improvements made in the areas of production environment, process control and microbiological quality of the product yield a reduction in the duration of fermentation and emergence of products that are free of health-risks, consistent quality capable of mass production through the use of mechanized equipment and sterile packages. The challenges of indigenous fermented foods consist of poverty, illiteracy, government attitude and preference for imported foods. The findings of this research will contribute to the scientific understanding of the microbial and biochemical processes involved in fermentation. This knowledge can spur innovation in food technology and microbiology, leading to new applications and improvements in food production. Based on the findings, it was recommended that Government agencies and development organizations should provide support and resources to small-scale producers of indigenous fermented foods. Also, strategies should be developed to facilitate market access for producers of indigenous fermented foods.


    Prospects and Constraints of Improvement on Indigenous Fermented Foods

    CHAPTER ONE

    1.1 Introduction

    Indigenous fermented foods hold a significant place in the culinary traditions and cultural heritage of various communities around the world. These foods, produced through natural fermentation processes involving local microbial communities, are not only integral to regional diets but also offer unique flavors, textures, and nutritional benefits. They often represent centuries of traditional knowledge and practices passed down through generations. However, despite their cultural importance and potential health benefits, indigenous fermented foods face several challenges that hinder their broader acceptance and commercialization. These constraints include inconsistent quality, safety concerns, lack of standardized production methods, and limited scientific research on their health benefits and fermentation processes. Improving indigenous fermented foods involves leveraging modern scientific techniques and knowledge to enhance their safety, nutritional value, and sensory attributes while preserving their traditional essence. This can include optimizing fermentation processes, developing starter cultures, improving hygiene practices, and conducting in-depth research on the health impacts of these foods.

    Fermentation is one of the oldest methods of food processing known to humanity. Archaeological evidence suggests that as early as 6000 BCE, people in the Fertile Crescent were brewing beer and making wine. In East Asia, records of fermented soy products like soy sauce and miso date back to ancient China, over 2,000 years ago. Similarly, dairy fermentation to produce yogurt and kefir has been practiced for centuries in the Middle East and Central Asia. The scientific exploration of fermentation began in earnest in the 19th century with the pioneering work of Louis Pasteur. His studies on the fermentation process in the 1850s laid the groundwork for modern microbiology and the industrialization of fermentation. Pasteur’s work revealed the role of microorganisms in fermentation, transforming it from a mysterious art into a scientific discipline. Indigenous fermented foods have been an integral part of human diets for millennia, deeply rooted in the cultural and social fabric of communities worldwide. These foods are produced through natural fermentation processes involving diverse microbial populations that interact with local raw materials. Fermentation not only preserves these foods but also enhances their nutritional profile, improves digestibility, and contributes to their distinctive flavors and textures.

    The indigenous fermented foods constitute a group of foods that are produced in homes, villages, ad small cottage industries. They are sold to the rural populace who buy them for food and social ceremonies. The fermented foods are derived from substrates like roots, Legumes, Cereals, oil seeds, nuts milk, palm tree sap etc. (Oguntunde), 1989, (Akobundu and Iwuoha), 1992. Generally, these crops are not used as foods in their unfermented State because some of them are toxic or contain anti-nutrientional factors. in the distant past there was no verified date on the economic, nutritional, technical and quality control implications of the indigenous fermented foods. Only recently have food technologist, human nutritionist, Microbiologists and other applied scientists carried out multifaceted studies on indigenous fermented foods so that further development could be achieved. These led to application of biotechnology processes in selected indigenous fermented foods but it is strange that the commercial biotechnology sectors has shown limited interest in applying modern biotechnology to the problems of security and poverty in developing countries. The commercial firm would find it hard to recoup their investments (Gabrille, 1999). Despite these advances on indigenous fermented foods, there are a lot of constraints militating against indigenous fermented foods which has hindered the implementation of such findings.

    Fermentation has been used for several thousands of years as an effective and low cost means to preserve the quality and safety of foods.

    Camp bell – Plat (1996) stated that fermentation is the oldest known of food biotechnology. Food fermentation involves mixed culture of microorganisms that grows simultaneous or in succession. According to Stainkerus (1995) the traditional fermented foods contain high nutritive value. Food fermentation is important in developing countries where lack of resources limits the use of technique such as vitamins enrichment of foods and the use of energy and intensive process for food preservation. Some important indigenous fermented foods in Igbo Etiti Local Government Area are:

    Cereals: Burukuku, kunu and pap

    Legumes: Ugba or dawada, ogiri isi

    Tree Sap: Palm wine

    Tubers: Abacha, Fufu or Utara akpu, gari, Ekwurikwu, cassava flour.

    In Igbo Etiti Local Government area, women carry out fermented processing activities mostly. The production is Craft-based despite the dawn of science and technology. The techniques they use are labour intensive time consuming and have low productivities, with success depending upon observation of good manufacturing practice. According to IDRC (2003) vitamin A, Iron and deficiency resulting from poor processing by rural or local farmers is widely prevalent particularly in the developing world.

    The world health organization (WHO) estimate that as many as 228 million children are affected by vitamin A. The report further shows that iodine deficiency (IDD) even when mild reduces intelligence quotient by 10-15 points. The WHO reports identified iron deficiency as the most common nutritional disorder in the world and over one billion people, particularly women of reproductive age and pre-school children and working men. If not controlled, it leads to anemia, reduced work capacity, diminished learning ability and increased susceptibility to learning ability and increased susceptibility to infection and great risk of death associated with pregnancy and child birth. All these added to low wages and increasing poverty, high price of foods of animal origin accompanied with increasing population presents a frightening scenario in developing world.

    The need to achieve food security for the growing population calls for the adaptation of improved method of food fermentation. Food security remains on unfulfilled dream from more than 800 million people unable to leave healthy and active lives because they lack access to safe and nutrious food Klaus, (1999). The fight to achieve food security for the growing population has to take place one many fronts. Technology is one of such front and genetic engineering and biotechnology are interdependent options within that front. Biotechnology clearly can solve agricultural problem that traditional technology and others can not solve or can solve in a more costly manner (Klaus, 1999). Recent development in genetics enzymology, recombination technology and fermentation technology have led to advances in technology far beyond the original traditional and scope (BOSTID, 1992).


    1.2 Statement of Problems

    Investigation revealed that the traditional, artisanal methods used in the production of indigenous fermented foods often result in variations in product quality and safety. This inconsistency is primarily due to the use of natural or wild microbial cultures and the lack of controlled fermentation conditions. Inconsistent quality can affect consumer trust and limit the market potential of these foods (Steinkraus, 1996).

    Additionally, traditional fermentation processes are highly variable, depending on local practices, raw materials, and environmental conditions. This lack of standardization poses a significant barrier to scaling up production and ensuring uniformity in the final product. Without standardized methods, it is challenging to achieve consistency in taste, texture, and nutritional content (Tamang, 2010).

    Furthermore, traditional producers often face difficulties in meeting modern food safety and quality regulations. The regulatory frameworks in many countries are designed with industrial food production in mind and may not be well-suited to the unique characteristics of artisanal fermented foods. Navigating these regulations can be challenging for small-scale producers, limiting their ability to commercialize their products (Woods, 2019).


    1.3 Aim and Objectives of Study

    The aim of the study is to explore the prospects and constraints of improvement on indigenous fermented foods. In achieving this aim, the following specific objectives were laid out as follows:
