  • Essay / Pollen Essay - 1382

    INTRODUCTION1.1 Bee-PollenPollen is the male gametophyte of flowering plants and has, along with the ovule, the capacity to give rise to viable seeds. Pollen exists for some time as an independent unit and therefore contains most of the nutrients essential for life. Humans have long been a consumer of pollen and pollen-containing foods, although they rarely feel discomfort from contact with pollen. In many living organisms such as insects, pollen is essential to 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 pollen in bees (Apis cerena Fab.) is said to have found the source of the enzyme in Indian honey (Wakhle, Phadke and Nair, 1983). Bees collect pollen to meet their nutritional needs, as pollen provides them with proteins, minerals, lipids, vitamins and many other nutrients. Pollen is also very important for bees to produce royal jelly, which is rich in most essential nutrients. Royal jelly feeds the larvae of queens, queens and young workers. Pollen is an ultimate source of proteins that are directly used by older workers and young larvae of both sexes. Pollen is therefore essential for the normal growth and development of individuals as well as for the reproduction of colonies. Plate 1.1: Honey bee (Apis mellifera) with a load of pollen in the pollen basket of its hind legs. 1.2 Nutritional value of bee pollen. The carbohydrates in pollen are mainly polysaccharides like starch and cell wall materials. The sugar fructose, glucose......middle of the article......1983).1.7 Aims and objectives: The aim of this work was to establish the main conditions for obtaining a new product natural food from pollen, safe and with improved nutritional potential, to be used as a food supplement or as a functional ingredient to formulate other foods. The pollen matrices are subjected to lactic fermentation using lactic acid bacteria as a starter and their effects on some of the original characteristics have been studied. The main objectives of this work are:1. To collect bee pollen and bee bread from the honey bee colony.2. Separate the whey from the curd to use as a starter culture for bee pollen fermentation and prepare a pure starter culture for bee pollen fermentation.3. Perform solid-state fermentation of bee pollen by lactic acid bacteria from whey.4. Estimate and compare the nutritional value of fermented and unfermented pollen.
