 The objectives of this research were to produce crackers based on sorghum modified flour and to predict its shelf life using a critical moisture approach. The research was conducted in two stages. The first stage was to determine the best crackers of nine formulations. The second stage was to predict the shelf life of the best crackers formulation by using a critical moisture content approach. The best crackers were produced from a mixture of 50% sorghum modified flour, 50% wheat flour and 25% margarine. The products had a puffing ratio of 38,04 %, and hardness of 28.86 N. The moisture sorption isotherm curve of sorghum modified flour crackers could be described using a Hasley model. Using the critical moisture approach, sorghum modified flour crackers packaged in a metalized plastic and stored at 30°C and stored at 84% relative humidity, the product shelf life would be 207 days.

Chocomix chocolate beverage powder is one of the increased value-added cocoa products by Griya Cokelat Nglanggeran. The aimed of this study to estimate the shelf life using Accelerated Shelf Life Testing (ASLT) based on critical moisture content. Results showed that critical moisture content of Chocomix was 4.01 % (db). Moisture sorption isotherm (MSI) curve of Chocomix at 28oC was type II isothermic sigmoidal with 2 curves at the ranged of water activity between 0.24 and 0.68; and the equation was  y = 86.584X3 – 91.893X2 + 28.818X – 0.470. The calculation showed that estimated shelf life of Chocomix stored in 51.89 µm thick package at 28oC was 16.4 months.Keywords: chocolate powder, critical moisture content, moisture sorption isotherm, shelf life

Abstract In the processing, the red ginger powder was dried at 50°C. Red ginger powder is hygroscopic, so it is easy to absorb moisture. This research aims to determine (i) the isothermic absorption curve model in red ginger powder with different fineness modulus and (ii) the expiration date using the critical moisture content method in various types of packaging materials. Moisture sorption isotherm of red ginger powder was determined by the static gravimetric method at 300C. The relationship equilibrium moisture content between relative humidity (RH) is described by the Hasley, Chen-Clayton, Henderson, Caurie, and Oswin Models. The Estimated shelf life is determined using the ASLT (accelerated shelf-life testing) method and calculated using the Labuza model with a critical water content approach. The results obtained that moisture sorption isotherm red ginger powder has sigmoid shape a type II. Henderson is the model that illustrates the accuracy of the ISA curve of red ginger powder of 60 mesh particle size while the Chen-Clayton Model illustrates the accuracy of the ISA curve of red ginger powder of particle size of 80 mesh. The shelf life of red ginger powder is 60 mesh particle size and using HDPE, PP, and aluminum foil packaging which is stored at 75% RH and 300C temperature is 118.85 days, 467.63, and 609.26 days, respectively. The shelf life of red ginger powder 80 particle size is 148.17 days, 582.98 days and 759.54 days.
