Processing of fresh yam to dried yam flour can be accomplished using different drying techniques. Drying is one of the traditional preservation and storage technique. During this process the dried products are stabilized by reducing the water activity to such an extent that microbial spoilage and chemical reactions leading to deterioration of foods are inhibited. It leads to dried product with reduced weight, prolonged shelf life and requires less transportation charges. There are various drying techniques that may be employed for the drying of yam tubers which include solar, hot air oven, and freeze drying. Among the different drying processes, hot air oven drying is relatively economical and most commonly employed technique in food processing industries but it results in low quality product due to low temperature and long-time processing. While freeze drying and solar drying result in minimal loss of nutrients and other desirable quality characteristics. Freeze drying process normally consists of two steps: freezing, and drying of product due to sublimation of ice under reduced pressure. It is especially useful for drying foods which are sensitive to heat. Freeze dried foods are light, porous, mostly retain their texture and original shapes but it incurs high cost than any other conventional drying method (Barbosa-Cánovas & Vega-Mercado, 1996). The colour of freeze dried product resembles that of the fresh in comparison to the colour of conventionally dried products. Solar drier utilizes the energy of sun either by converting it to electricity or thermal energy which in turn heats the product to dryness. This technique is entirely different from traditional sun drying in which food material is directly exposed to sunlight. Solar drying is advantageous over sun drying as sun dried food products have high water activity which make them susceptible to microbial contamination. Solar dried food products are safe and void of any textural defects like case hardening. Thus, in this study the impact of different drying methods and blanching on molecular structure, physico-chemical and functional properties of elephant foot yam (A. paeoniifolius) flour were studied.
