Scientist, Central Institute of Agricultural Engineering, Bhopal Application of Artificial Intelligence in Food Processing SectorStatus of Food Processing Industries: Status of Food Processing Industries Size of food market in India - Rs. 8,60,000 Crores Primarily processed food market – Rs. 2,80,000 crore Value added processed food market – Rs. 1,80,000 crore Investment during the 10th plan is estimated at Rs. 62,105 Crores Industry growth rate during the last five years is estimated at 7.14% against GDP of 6.2% Investment required during next ten years – Rs. 1,10,000 crores Food Quality and Safety Issues are Prime ImportantUse of Artificial Intelligence in the Context of Food Processing: Use of Artificial Intelligence in the Context of Food Processing I n artificial intelligence the tolerance for imprecision and uncertainty is exploited to achieve tractability, lower cost, high Machine Intelligence Quotient (MIQ) and economy of communication Artificial intelligence makes use of multivalued or fuzzy logic Artificial intelligence can deal with ambiguous and noisy data Artificial intelligence can yield approximate answers but good enough to solve the practical problems of tradeArtificial Intelligence: Artificial Intelligence Artificial intelligence can be used to model and analyse very complex problems where conventional methods have not been able to produce cost-effective, analytical, or complete solutions. In agricultural and biological engineering, researchers and engineers have developed methods to analyse the operation of food processing. Fuzzy Logic (FL), Artificial Neural Networks (ANNs), Genetic Algorithms (Gas), Bayesian Inference (BI), Decision Tree (DT), and Support Vector Machines (SVMs)Complex Food Process Control: Complex Food Process Control A single sensory property like color or texture can be linked individually to several dimensions recorded by the human brain. The food industry works with non-uniform, variable raw materials that, when processed, should shaped into a product that satisfies a fixed standard. The process control of foods are highly non-linear and variables are coupled. In addition to the temperature changes during a heating or cooling process, there are biochemical (nutrient, color, flavor, etc.) or microbial changes that should be considered. The moisture in food is constantly fluctuating either loss or gain throughout the process which can affect the flavor, texture, nutrients concentration and other properties. Other properties of foods such as density, thermal and electrical conductivity, specific heat, viscosity, permeability, and effective moisture diffusivity are often a function of composition, temperature, and moisture content, and therefore keep changing during the process. The system is also quite non-homogeneous and hence detailed input data are not available. Often, irregular shapes are present.ANN for Crispness of Snack Foods: ANN for Crispness of Snack Foods The crispness was evaluated by acoustic testing. The acoustic patterns were generated by crushing the snack samples with a pair of pincers The inputs for training the NNs comprised 102 amplitudes of sound signals in 0–7 kHz frequency range at the intervals of about 69 Hz with crispness grades as outputs P robabilistic (PNN) models showed good performance in classifying the snack foods into four grades of crispness. The prediction accuracy of models ranged approximately from 96 to 98% Plot of average amplitude of acoustical signal spectrum for different moisture content of Pringles potato chip samplesDetection of Plant Diseases: Detection of Plant Diseases Electronic nose incorporating AI was used to detect plant disease caused by Ganoderma boninense fungus affecting oil palm. The electronic nose, Cyranose 320, has the front end sensors and artificial neural networks for pattern recognition. The system was able to differentiate healthy and infected oil palm with a high rate of accuracy.Detection of Spongy Tissue in Mango: Detection of Spongy Tissue in Mango "spongy tissue", affects about 30% of ‘Alphonso’ mangoes Fruits show no external symptoms at harvest or on ripening but cutting reveals internal damage which adversely affects fruit quality. Both fully grown green, unripe mangoes and ripe fruits show spongy tissue. A non-destructive x-ray inspection can detect affected mangoes. The method could be used for quality control for on-line detection and separation Central Electronics Engineering Research Institute (CEERI)ANN in image recognition and classification of crop and weeds: ANN in image recognition and classification of crop and weeds The images were taken, Colour index values were assigned to the pixels of the indexed image and used as ANN inputs. There were 80 images, 100x100 pixels, for training, and 20 images for testing. Many back propagation ANN models were developed with different numbers of PEs in their hidden and various output layers. Six different evaluation schemes for two ANN output strategies were used. The performance of the ANNs was compared and the success rate for the identification of corn was observed to be as high as 80 to 100%, while the success rate for weed classification was as high as 60 to 80%. The results indicated the potential of ANNs for fast image recognition and classification. Fast image recognition and classification can be useful in the control of real-world, site-specific herbicide application.Milestones of AI in Food Processing: Milestones of AI in Food Processing 2004 Brudzewski et al.
