The market of bioactive functional ingredients and biotherapeutics has been increased to US $ 167 billion per year at a 7.3% increase in 2014 and is expected to US $ 279 billion by the end of 2021 (www. transparencymarketresearch.com). The specific components of my research pertain to the molecular and biochemical characterization as well as scale up production of probiotic and fungal recombinant enzymes in order to: (i) produce and demonstrate the suitability of those enzymes derived bioactive compounds as functional food ingredients and biotherapeutics, and (ii) develop health promoting probiotics (anti-cholesterol, anti-cancer, anti-obesity, etc). Among 10 different enzymes were genetically overproduced up to 1,000 folds in different hosts, two recombinant enzymes (lipase and aminopeptidase) have been scaled up to 1,500 liter reactor with excellent performance and reliable results at all scales.
After screening the robust probiotic strains by conventional and metagenomic methodsfive commercial probiotics and their enzymes were developed: (1) cholesterol reducing bile salt hydrolase (BSH) active strain, (2) anti-hypertensive peptide producing and accelerated cheese ripening aminopeptidase active strain, (3) transgalactosyl and hydrolytic lactase producing strains which produce large amounts of galacto-oligosaccharides (GOS) and lactose free milk, (4) esterase/lipase active strains which produce a large amount of natural butyric acid (pro drug) and strong esterification (inter- and trans-) activities, and (5) conjugated linoleic acid (CLA) producing strains with anti-obesity and anti-cancer properties. Those applications are immense and some of these data will briefly be presented.

Keynote: Sensory, nutritional and health benefits, formulation and product development of steviol glycosides isolated from Stevia rebaudiana
Time : 11:00-11:30
Dr Chaturvedula has an extensive experience in the Organizations of Food/Beverage, CPGs, Natural Ingredients, Nutraceuticals, Dietary Supplements, Health and Wellness Products, Pharmaceutical, and Bio-Technology. Well-known and internationally reputed ‘Subject Matter Expert (SME)’ in the field of ‘Sweeteners and Sweetness Enhancers’ across the Globe with more than 40 patents/applications and over 65 peer reviewed research articles, several book-chapters, review articles and presentations in the area of natural sweeteners like Stevia rebaudiana (Stevia), Luo Han Guo/Siraitia grosvenorii (Monk Fruit) and many other.
The most widely used sweetener in the world is ‘Sucrose’. Several reports indicated that a high daily intake of sucrose develops metabolic disorders and health problems leading to obesity and dental caries; though no specific evidence directly related to diabetes. But high amount of sucrose found to cause weight gain and adverse effects on glucose intolerance. At present, high potency artificial sweeteners are playing a major role in the food and beverage industry worldwide. Recent studies suggest that ‘Stroke and Dementia risk linked to Artificial Sweeteners’ and these findings raised new questions about whether drinks flavored with artificial sweeteners can increase the risk of serious illness, as heavily sugared drinks have already been shown to do!
Due to growing consumer’s desire to control caloric intake more closely as well as potential implications of high potency artificial sweeteners, in recent years, a need for novel natural sweeteners has increased. This leads to the discovery of non-caloric alternative natural sweeteners. Over the past few decades, Stevia rebaudiana leaves have been the source for isolation of a large number of sweet steviol glycosides with varying molecular structures. Steviol glycosides found to possess a sensory characteristic superior to other high potency sweeteners into various food and beverage systems. An overview of ‘Sensory, Nutritional and Health Benefits, Formulation and Product Development of Stevia glycosides isolated from Stevia rebaudiana’ will be discussed

Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric diagnoses in childhood and adolescence and may persist into adulthood. ADHD is characterized by behavioral symptoms such as inattentiveness, hyperactivity and impulsiveness. Medications such as methylphenidate have been shown to yield short-term symptom reduction and other beneficial outcomes in many individuals with ADHD. However, the extent of the efficacy of medication remains a matter of debate. In addition, the long-term pharmacotherapy of ADHD has been shown to have no proven efficacy and to be associated with adverse effects. This highlights the need to find alternative treatment approaches. Growing evidence suggests a significant relationship between quality of diet and mental health. Various nutrients have been linked to brain development and functioning, and diet may be an important factor in the high incidence and prevalence of psychiatric disorders including ADHD. Dietary improvement is therefore thought to be able to assist in the prevention and therapy of ADHD. Major food compounds proposed to be involved in the etiology of ADHD and to have therapeutic efficacy include polyunsaturated fatty acids and micronutrients such as minerals and vitamins. Furthermore, artificial food additives have been suggested to play a role in the etiology of ADHD and elimination diets have been tested for their therapeutic effects. There is currently no clear evidence supporting a role of single nutrients in the etiology and therapy of ADHD. However, the relationship between the whole diet and ADHD may be of greater importance.

Today’s mainstream food preservation methods mostly depend on two dimensions- namely time and temperature and have several drawbacks. The use of heat (pasteurization, sterilization and blanching, etc.) can destroy nutrients such as thermally labile vitamins and also components responsible from product flavor and taste. It can also produce some undesirable compounds originated from Maillard reaction and caramelization. All of these changes result in products that are far from being original. This contradicts with modern consumers’ desire for the fresh and natural food products bringing the need for alternative non-thermal processing methods. Among these High Hydrostatic Pressure (HHP), has been recently branded-patented as “Pascalization”. Its main difference from conventional thermal processing is the addition of the third variable-pressure- in addition to lower heat / shorter time combination with respect to traditional thermal treatment making it a 3-D process. The process is fast, safe, effective and globally producing food-edible products without any additives or preservatives ranging from meat-dairy-seafood-deli to fruit/vegetable juices and even pet food. HHP technology has been also quoted as being one of the best innovations in food processing in the last fifty years. The pros and cons of this technology with recent applications in modeling with food safety requirements and consumer acceptance will be summarized together with the current facts and myths.

Michael’s strengths are in leadership, process improvement, S&OP, contract negotiations and execution. He has a customer first mentality with the focus of finding mutually beneficial partnerships.
Statement of the Problem: Transportation is a key component to any supply chain. Specifically, in the Food and Beverage industry, with new regulations in place for Food Safety and driver’s hours, a lean supply chain with a comprehensive and robust transportation network able to scale with the necessary agility to meet quality and service standards. is as critical as ever. Companies in this space are faced with the task of understanding these new regulations and the impact they will have on their supply chain forcing them to analyze their supply chain and transportation network. Will they determine to adjust internal S&OP? Will they pass the burden along to their suppliers and implement VMI? Will they source locally? Build smaller regional facilities to lower total cost of transportation? Are they ready to handle the changes? Etc. Will these changes help compete with Amazon? These are a few of the challenges companies in the Food and Beverage space are faced with when it comes to logistics and distribution. There is no one-size-fits-all solution, however there are ways to be best prepared to take their supply chain to the next level without issue during this time of change.

At the beginning of the 20th century, Ellie Metchnikoff (1845–1916), Ernest Moro (1874–1951), and Leo Rettger (1874–1954) made their first scientific contributions to the research on probiotics. In humans, lactic acid bacteria (LAB) have a strong influence on the host’s health because LAB are an important biodefense factor for preventing colonization by and subsequent proliferation of pathogenic bacteria in the intestine. Probiotics is largely used for the production of fermented products of animal (dairy) and plant origin. Recently, fruit or vegetable products containing probiotics are preferred by some consumers. In the formulation of fruit or vegetable probiotic products, Lactobacillus acidophilus, L. casei, L. plantarum, L. rhamnosus and Bifidobacterium lactis are most utilized. European, American and Asian (especially in Japan and South Korea) markets already commonly sell probiotic products from fruits and vegetables. Lactobacillus plantarum, as a heterogeneous and versatile species that is encountered in a variety of environmental niches, including fermented food products, such as dairy, meat, fish, and vegetables, as well as plant matter. This species exhibits various biological effects such as antitumor, anticoagulant, antiviral, immune modulatory and anti-inflammatory, anti-diabetic, and anti-oxidant or free radical scavenging activity. My research group discovered that L. plantarum strains isolated from kimchi and infant feces. These strains have a high survival rate in low pH conditions. Proteins isolated from L. plantarum L67 could stimulate the apoptotic signals and then consequently induce programmed cell death in HT-29 cells. The results in this study suggest that L. plantarum L67 could be used as a probiotic culture for the production of dairy or vegetable fermented foods. Some companies insist that plant origin-probiotics are superior than animal-origin probiotics without any scientific data that supports the claim. How are plant proteins much better than animal proteins for human health? Simple answer is that it is not.

Statement of the Problem: Fish processing by-products (frames, heads, viscera and etc.) can account for 60-70% of the total fish after industrial filleting. The 60-70% of by-products contains highly nutritious fish muscle proteins and fish oil rich in heart-friendly omega-3 fatty acids. The proteins and oil could be recovered and used subsequently in the development of human food products and dietary supplements. The objective was to determine chemical properties of heat-set gels made of the isoelectric solubilization/precipitation (ISP) protein isolate fortified with ω-3 polyunsaturated fatty acids (PUFAs)-rich oils (flaxseed, fish, algae, krill, and blend). Methodology & Theoretical Orientation: Fish protein isolate (FPI) was recovered from whole gutted trout using ISP. FPI was used as a main ingredient in heat-set gels made with ω-3 PUFAs oils (flaxseed, algae, fish, krill, and blend). Findings: Fortification of the ISP-recovered fish protein isolate with ω-3 PUFAs rich oils (flaxseed, fish, algae, krill, and blend) resulted in increased (P < 0.05) content of alpha-linolenic (ALA), eicosapentaenoic (EPA) and docosahexaenoic acids (DHA) in the cooked protein isolate gels. The extent of the PUFAs increase, ω-6/ω-3 FAs and unsaturated/saturated FAs ratios, as well as the indices of thrombogenicity and atherogenicity depended on specific ω-3 PUFAs-rich oil used to fortify the protein isolate gels. Lipid oxidation in ω-3 PUFAs fortified gels was minimal, although greater (P < 0.05) than control gels (without ω-3 PUFAs fortification). However, all gels were in the slightly rancid, but acceptable range. The shear stress of ω-3 PUFAs fortified gels was generally greater than the control gels. Conclusion & Significance: This study indicates a potential application for protein isolates recovered with ISP from fish processing by-products or whole fish without prior filleting. Fortification of the ISP protein isolate with ω-3 PUFAs-rich oils allows the development of a functional seafood product.

Prebiotic oligosaccharides have attracted an increasing amount of attention because of their physiological importance and functional effects on human health, as well as their physico-chemical properties, which are of interest for various applications in the food industries. Galacto-oligosaccharides (GOS), one of the major groups of prebiotic oligosaccharides, are formed via the transgalactosylation reaction from lactose. This reaction is catalyzed by a number of b-galactosidases (lactases) in addition to their hydrolytic activity. GOS are complex mixtures of different oligosaccharides, and the spectrum of the oligosaccharides making up these mixtures strongly depends on the source of the enzyme used for the biocatalytic reaction as well as on the conversion conditions used in their production. These oligosaccharides are of great interest because of their proven prebiotic characteristics. A plethora of GOS is also found in human milk, and these differently substituted oligosaccharides are associated with a number of beneficial effects for the breast-fed infant.

Problem Statement: food security through adequate supply and the concordant protection of the domestic production in Nigeria especially for a staple food like rice is a major issue. Earlier in the 90’s a total ban on rice importation was introduced which was later lifted, since then there have also been irregular stints of such import policy. Did the import restriction boost rice domestic production? What are the macroeconomic determining factors of the Gross Domestic Rice Product (GDRP)? The purpose of this study is to find & proffer valid solutions to the age long problem of rice self-sufficiency through a better understanding of policy measures used then. Methodology & Theoretical Orientation: analysis using; Cointegration, Vector Error Correction Model (VECM), Impulse Response Function (IRF) and Granger Causality Test (GCT) for time series dataset of the variables; GDRP, Gross Fixed Capital Formation (GFCF), average foreign rice producers’ prices (PPF), domestic producers’ prices (PPN) and the labour force (LABF), import restriction dummy variable, POL1. Findings: in the short-run error correction specification for GDRP, a percentage (1%) deviation away from the long-run equilibrium in current quarter is only corrected by 0.14% in subsequent quarter, the rice import restriction policy had no significant effect on the GDRP, and policy period had effects on the PPN and LABF. Variables employed are valid macroeconomic factors that explain the GDRP of Nigeria, as adduced from the IRF and GCT, and in the long-run. Policy Recommendations: suggestions that the import restriction is not totally dismissed as a veritable tool for improving domestic rice production, rather better enforcement procedures and strict adherence to the policy dictates is needed, accompanying policies which drives public and private capital investment and accumulation must be introduced. Employment and labour substitution in the agricultural sector should not be distorted; rather its welfare and efficiency be supported.

The food industry is increasingly moving toward new product development and innovative propositions through new processing methods that allow doing things you could not do before. Thermal treatments have traditionally been used in the food industry to provide the required safety profiles and to extend product shelf-life. However, heat treatments lead to damage of temperature-labile compounds, resulting in partial loss of organoleptic and nutritional properties of food products. In recent years, the potential of novel thermal and non-thermal technologies for food processing has gained industrial interest. Since these technologies allow the food sector to meet product safety and shelf-life requirements while reducing the impacts on food quality attributes, they have potential to replace, at least partially, the traditional food preservation techniques. Therefore, non-thermal technologies are widely employed for food applications, e.g. high power ultrasounds, pulsed electric fields, light technologies, cold plasma, etc. The term “non-thermal” is used for technologies that are effective at temperatures below the lethal temperatures of microorganisms, even though some of them may lead to indirect temperature raises in the product. The non-thermal processing is used for all foods for its better quality, acceptance, and for its shelf life also reduces the operational cost. Innovative method have better potential than others conventional method and still an evolving challenging field. The various emerging technologies in food processing and preservation are hurdle technology, high pressure processing, ultrasonication etc.

Strawberry is one of the most popular fruits worldwide. Therefore, it is important to consider the stability of fruit supply and maintenance of freshness from the production area to the point of consumption. Strawberries deteriorate rapidly, storage delays quality changes. However, little is known about the effect of storage methods on the changes in fruit quality. Thus, in this study, two storage methods; Cold Storage (CS) and Modified Atmosphere Packaging (MAP) were investigated on the strawberry fruit parameter keeping quality.
Results obtained showed that storage method has an effect on fruit keeping quality, and it proved that MAP is the acceptable storage method because it kept on strawberry fruit quality, extended storage period, decreased weight loss, in contrast it showed the highest fruit decay.
