The basics of food dehydration. The effect of sample weight was studied and the results were compared with those obtained by conventional and vacuum oven drying methods. 6.1.2 Moisture Content of Foods The moisture content of foods varies greatly as shown in Table6-1 (4). The determination of moisture content in glycerol infused intermediate moisture beef was studied. Intermediate moisture foods have an S-shaped isotherm with a flat spot in the middle. %%EOF. <<8bd056e399879b4c903b895c5ec70a2a>]>> Moisture in foods occurs in two forms: (1) water bound to ingredients in the food (proteins, salt, sugars), and (2) free or unbound water that is available for microbial growth. The ambient air contains moisture and raising its temperature simply lowers its relative humidity causing a lower equilibrium moisture content.

The determination of moisture content in glycerol infused intermediate moisture beef was studied. 0000003815 00000 n Mold generally cannot penetrate deep into the product. xref The moisture content of a food material is defined through the following equation: %Moisture = (mw / msample) � 100 Where mw is the mass of the water and msample is the mass of the sample. Moisture content of a food product will affect its stability and quality. These food products are below the minimum water activity for most bacteria (0.90), but are susceptible to yeast and mold growth. 0000005203 00000 n The results obtained in this work confirmed that usual gravimetric procedures (oven or vacuum oven) for determinating moisture content may give Moisture in a weighed sample is removed by heating in an oven under specified conditions of time, temperature and vacuum and the residual dry substance weighed (Note 1). The monolayer moisture content is usually considered the lowest value to which food and agricultural material can be dried to ensure product stability [47, 48]. To summarize common moisture content measurement methods for dried food products with respect to the measurement principle, typical applications, and the advantages and limitations in the food industry so that the suitability of each method to the small-scale farming and co-operative context can be assessed. %%EOF Percentage moisture is generally determined in one of two ways 1) using a convection oven or 2) using a rapid moisture analyzer. The combination of these events helps to prevent spoil-age in dried food.
