INTRODUCTION1.1 Bee pollenPollen is the male gametophyte of flowering plants and has, together with the ovule, the ability to give rise to viable seeds. Pollen exists for a certain period as an independent unit and therefore contains most of the nutrients essential for life. Man has long been a consumer of pollen and pollen-containing foods, although he has rarely felt discomfort upon contact with pollen. In many living organisms such as insects, pollen is essential for their life cycle, being particularly rich in proteins (Wakhle, 1981). Once bee pollen was defined in legislation as a food, the nutritional value of this product became important. It contains a high concentration of reducing sugars, essential amino acids, fatty acids, minerals and is abundant in proteins and vitamins (Campos, 2010). The enzymatic activity of honey bee pollen (Apis cerena Fab.) has been reported to find the source of the enzyme in Indian honey (Wakhle, Phadke, & Nair, 1983). Bees collect pollen to meet their nutritional needs, because pollen provides bees with proteins, minerals, lipids, vitamins and many other nutrients. Pollen is also very important for honey bees to produce royal jelly which is rich in most essential nutrients. Royal jelly nourishes the larvae of the queen, queen bee and young worker larvae. Pollen is the main source of the protein which is used directly by older workers and young larvae of both sexes. Therefore pollen is essential for the normal growth and development of individuals and for the reproduction of colonies.

The sugar fructose, glucose...... middle of the paper ......1983).1.7 Aims and objectives: The aim of this work was to establish the main conditions for obtaining a new natural food product from pollen, safe and with improved nutritional potential, to be used as a food supplement or functional ingredient for the formulation of other foods. The pollen matrices are subjected to lactic acid fermentation using lactic acid bacteria as starters and their effect on some of the original characteristics has been studied. The main objectives of this work are:1. Collect pollen and bee bread from the honey bee colony.2. To separate whey from curd for use as a starter culture for bee pollen fermentation and to prepare a pure starter culture for bee pollen fermentation.3. To carry out solid state fermentation of bee pollen by whey lactic acid bacteria.4. To estimate and compare the nutritional value of fermented and unfermented pollen.
