The concluding Chapter 12 of my book Rice Technology, titled “Commercial Aspects of Milling Business,” focuses on the fundamental business principles of rice milling. While these concepts are generally well understood within the business community, they are often overlooked by technical professionals like myself. Interestingly, I once had a discussion with a seasoned businessman on this subject. To my surprise, after reviewing these basic principles, he revisited and restructured his approach—and is now reaping significant rewards. This experience reinforced my belief that even fundamental commercial insights, when applied correctly, can drive meaningful results. I continue to emphasize the importance of these concepts to commercial professionals and investors in the rice industry. A major opportunity lies in value addition. Significant potential exists in by-products such as rice bran, paddy husk, and brown rice. With focused investment in commercial research and development, these segments can generate enhanced margins and long-term profitability. While the basmati segment has already leveraged value addition effectively, there remains tremendous untapped potential in the non-basmati sector. In this context, I am sharing a representative and indicative calculation sheet highlighting the value addition potential of brown rice. This serves as a starting point for further exploration and investment decisions. The figures are tentative but illustrate the scope clearly—value lies not just in milling, but in how intelligently we utilize every output of the process.

This week’s blog is a humble prayer for peace, harmony, and tranquility across the world. In times when conflict overshadows humanity, our thoughts turn toward the people affected by the ongoing tensions in West Asia. Beyond borders, politics, and ideologies, it is the ordinary lives that bear the greatest cost of war. Let us come together, not just as professionals or communities, but as global citizens—united in hope, compassion, and prayer. May peace prevail.May humanity rise above conflict.And may this war find its peaceful conclusion soon. Because prayers, when offered with sincerity, never go unanswered.Amen.

It has been a satisfying journey sharing my experiences in various aspects of Rice Technology. As we approach the concluding chapters of this series, I am pleased to present insights from the 11th Chapter: Rice Fortification and Enrichment Technologies—a crucial and impactful domain in modern food processing. Rice fortification is an advanced process aimed at addressing nutritional deficiencies in populations. In this technology, broken rice is finely ground, blended with essential nutrients, and then processed through cold extrusion to recreate rice-shaped kernels. These fortified kernels, often referred to as vitamin premix, are blended with regular rice in small proportions (typically 1–2%) to achieve targeted nutritional enhancement. This approach plays a vital role in combating micronutrient deficiencies at a community level. On the other hand, rice enrichment is a premium process, particularly relevant for value-added varieties such as Basmati rice. In this method, the nutritional profile of brown rice is restored in polished rice—excluding components like oryzanol and dietary fiber. This is achieved by incorporating a specialized premix, thereby enhancing the overall nutritional value while maintaining consumer-preferred texture and appearance. Additionally, there are cost-effective alternative technologies available that ensure nutrients remain intact even after rinsing or soaking. These methods are simpler to implement and involve significantly lower capital (CAPEX) and operational (OPEX) costs, making them highly viable for large-scale adoption. Taking this forward, I have undertaken the initiative to introduce this technology to the market at accessible and reasonable pricing. In the coming weeks, Lotus aims to launch its own Fortified Rice Premix for both domestic and industrial applications. Conclusion Rice fortification and enrichment are not just technological advancements—they are powerful tools to improve public health. With the right implementation, these innovations can significantly contribute to reducing nutritional deficiencies and enhancing food quality on a large scale.

After a brief pause of three weeks from writing on Rice Technology, I am pleased to share the 10th chapter, focusing on Rice Husk Value Addition Techniques. This week is personally special for me, as I reflect on my four-decade-long journey with Rice Technology — what began as an infatuation has now evolved into a lifelong passion. It is with this emotional connection that I turn to a critical yet underutilized area: value addition of rice husk. One of the most promising opportunities lies in preserving silica in its amorphous form through controlled combustion of rice husk at approximately 830°C. This process enables the production of high-purity amorphous silica, which commands a market price of ₹50–70 per kg. Today, husk-based boilers have become an integral part of rice milling operations. However, the resulting husk ash is often treated as a disposal challenge rather than a valuable resource. This presents a significant opportunity for the industry to shift perspective — from waste management to value creation. By adopting controlled combustion techniques, rice millers can convert husk ash into 100% pure amorphous silica, unlocking a new revenue stream. While the technology is already proven and tested, the primary barrier remains its high initial cost. Therefore, the immediate focus should be on conducting commercial trials aimed at making this solution more cost-effective and scalable. Given the low associated risk and high potential returns, it is imperative for millers and industry stakeholders to step forward and invest in this promising technology.

The ninth chapter of the book Rice Technology focuses on Brown Rice Value Addition Techniques. The most nutritious part of paddy is the rice bran, which contains essential nutrients such as thiamine, riboflavin, niacin, iron, zinc, dietary fiber, and oryzanol. These components make brown rice one of the most nutritionally valuable food grains. Rice polishing is often considered a “necessary evil” that demands serious attention today. Polished rice, though preferred for its taste and appearance, is primarily a source of carbohydrates. The removal of rice bran during polishing significantly reduces its nutritional value, making it less healthy by modern dietary standards. While polishing improves palatability, limited efforts have been made to enhance the acceptability and taste of brown rice to match that of polished rice. One practical approach could be the inclusion of rice bran in polished rice packaging. Although this idea appears simple, it is technically challenging to implement. However, when polished rice is cooked with rice bran, the flavor remains comparable to polished rice, while the nutritional value becomes equivalent to that of brown rice. Cleaning rice bran, stabilizing its oil content, and packaging it into small pouches represent a promising value addition strategy. Even a spoonful of purified, stabilized rice bran consumed daily can serve as a powerful nutritional supplement. Such innovations can pave the way for healthier rice consumption and sustainable value-added rice products.

Strengthening the Parboiling Process: Reflections Beyond Chapter 4 of Rice Technology While I discussed the fundamentals of the parboiling process in Chapter 4 of my book Rice Technology, I feel the need to further articulate my perspective—particularly in light of practical challenges and opportunities that still exist in the industry. Early Work on Parboiling Upgradation (1993–1996) Between 1993 and 1996, I had the privilege of assisting Dr. K. R. Bhattacharya in upgrading the conventional parboiling system. Over these three years of focused and intensive work, we examined nearly every critical parameter influencing parboiling performance. Our work primarily involved Basmati rice parboiling, which presented a unique and demanding challenge:the rice had to retain its superior cooking qualities, especially: 2.5 times elongation Distinct ring formations along the grain length While hygiene and process cleanliness were important considerations, preserving cooking quality remained the most critical and technically challenging aspect. Process Optimization Through Controlled Experimentation We conducted extensive permutations and combinations involving: Soaking temperature versus soaking time Residence time during steaming Steam intensity and exposure duration Through systematic experimentation and commercial-scale trials, we successfully achieved our objective. The improved process was subsequently adopted by the rice milling fraternity, marking a significant milestone in practical parboiling technology. However, I must emphasize that the industry has largely stagnated at this point of adoption, without sufficiently exploring further improvements required to meet present and future challenges. Dry Heat Aging and the Need for Further Innovation The introduction of Dry Heat Aging was a commendable advancement, primarily aimed at: Reducing working capital costs Minimizing long-term storage requirements Lowering interest burdens on inventory Yet, while Dry Heat Aging addressed storage and financial concerns, parboiling itself still holds untapped potential, particularly in reducing power consumption. Pressure-Based Soaking and Steaming: A Breakthrough To address this, we explored methods to reduce soaking time, experimenting with: Vacuum-based soaking Pressure-based soaking Our trials conclusively showed that soaking under pressure was significantly more effective, enabling us to reduce soaking time to just two hours—a result validated through full commercial-scale trials. Encouraged by this success, I extended the concept to include: Soaking under pressure Steaming under pressure The results were astonishing and exceeded expectations. This development challenged some long-held assumptions, including those of my revered Guru, Dr. K. R. Bhattacharya. His gracious acknowledgment and blessings for this achievement remain a deeply cherished memory for me. The Way Forward: Continuous Parboiling and Energy Integration The purpose of sharing these insights is not merely retrospective—it is a call to action for the rice milling fraternity. I strongly believe that the future lies in making the parboiling process continuous, which would allow: Effective utilization of back-pressure steam Integration with steam turbines for captive power generation A drastic reduction in net power costs—potentially to negligible levels Such integration would significantly enhance millers’ margins, improve energy efficiency, and ensure long-term sustainability in rice processing.

Chapter 4 of Rice Technology addresses one of the most intricate aspects of paddy processing, particularly for Indica varieties. This chapter focuses on Enhanced Aging of Paddy and Parboiled Rice, a subject critical to improving rice quality, cooking behavior, and milling yield. Parboiling and enhanced aging involve treating paddy varieties having diverse Gelatinization Temperatures (GT) and gel consistency, both of which are intrinsic properties of starch. Managing these variations is essential to achieving uniform quality in the final rice product. One of the simplest and fastest aging techniques adopted by rice millers is the steaming process. This method is now well established, with pressure steaming also widely practiced. While steaming does impact the chalkiness of rice, initial resistance to chalky appearance gradually diminished as millers and consumers recognized the significant improvement in cooking quality. Today, steaming has become a standard practice in modern rice milling. However, premium rice varieties such as Basmati, Sona Masuri, Badshah Bhog, and Zeera rice have explored an alternative route—the dry heat aging method. This process employs conductive heating, followed by tempering, where paddy is rested for 60 to 300 minutes under controlled conditions. During this phase, moisture absorption is strictly avoided, and appropriate cooling is adopted. Although dry heat aging is both complex and capital-intensive, many millers adopt it discreetly due to its fast return on investment. The primary reason is the superior palatability of the rice, with negligible increase in chalkiness and cooking characteristics comparable to 18 months of natural aging. My exposure to Thailand’s rice milling practices prompted deeper exploration into high-moisture paddy preservation. Both steaming and dry heat aging require paddy moisture levels between 14% and 16%, whereas natural climatic conditions often reduce moisture below 12%, leading to increased grain breakage during aging. A practical solution to this challenge is chilling the paddy, which allows rice millers to perform fast aging throughout the year without compromising grain integrity. India has developed high-quality grain chiller manufacturing capabilities, presenting a significant opportunity for the industry to achieve consistent quality and improved milling yields. The evolution of the parboiling process has demanded significant efforts to move beyond the conventional “Kacchi and Pacchi” methods. I consider myself fortunate to have contributed to a breakthrough in this area under the mentorship of Dr. K. R. Bhattacharya, an eminent Rice Chemist, whose guidance played a pivotal role in advancing these techniques. I also recall the industry-wide challenge of “musty smell” encountered in 1995, for which effective solutions were provided to the entire rice milling fraternity. Today, multiple processing routes—ranging from nominal pressure steaming to high-pressure steaming—can be adopted to meet the diverse quality requirements of global customers.

My accidental infatuation with Rice Technology gradually turned into a permanent love—one that has made every moment of my rice-milling career deeply rewarding. I truly cherish those experiences, and I am delighted to share them on this august platform with the rice-milling fraternity. Stabilizing the paddy-drying process and subsequently adopting bulk storage in silos transformed rice milling into a transparently automated business. These advancements also made real-time ERP solutions not only possible but essential. In the third chapter of my book Rice Technology—titled “Rice Milling Instrumentation for Optimization of Yields”—I explored various approaches to generating Profit & Loss (P&L) statements on a daily basis. The pace of technological change now suggests that the time is near when such P&L insights could be updated hourly. Choosing the right hardware, integrating it through SCADA, and ensuring seamless compatibility with ERP systems are all critical for real-time data accuracy. In rice milling, the right instruments make all the difference. Today, with rapid IT innovations and the explosive rise of AI systems, even more possibilities are emerging. AI-driven tools can significantly reduce—and in some cases eliminate—errors across mill operations. This not only improves efficiency for the rice miller but also ensures that farmers benefit more consistently and transparently.
