Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Standardization of technology for enzymatic extraction of tamarind pulp and its drying to prepare effervescent beverage tablet
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Bisht, Shivani; Sabbu Sangeeta
    India is one of the largest producers and consumers of tamarind. The pulp of tamarind claims various therapeutic properties and is used as a favourite ingredient in different culinary preparations. Traditional process of pulp extraction and drying of tamarind is cumbersome and inefficient with low recovery and poor quality. Further, options for consumption of tamarind are limited and mostly inconvenient. Therefore, present investigation was aimed at developing a technology for enzymatic pulp extraction from tamarind and its foam mat drying followed by preparation of effervescent beverage tablet to enhance process efficiency and provide an acceptable and more convenient product. For tamarind pulp extraction, two enzymes i.e. pectinase and cellulase and their mixture in ratio 1:1 (@ 0.1, 0.3, 0.5 and 0.7 %) were evaluated. Pectinase : cellulase enzyme mixture (1:1 w/w) @ 0.3 % was found best w.r.t. higher TSS, extractability of solids and pulp yield. The optimized pulp was mixed with different concentrations (10, 15, 20 and 25 % on db) of three drying aids i.e. gum arabic, maltodextrin and inulin followed by foam mat drying. Maltodextrin @ 20 % proved to be an ideal drying aid with better recovery (74.08 %) of tamarind pulp powder. The powder thus formed was mixed with fixed levels of black salt, jeera powder and sugar-free natura and varying levels of citric acid (12 - 18 %) and sodium bicarbonate (6 - 12 %) as effervescent agents, followed by compressing in a tablet making machine. It was found that the tablets formulated using 15 % citric acid and 9 % sodium bicarbonate had lower disintegration time (2.84 min.) and higher overall consumer acceptability (8.75). The cost of four tablets required to prepared one serving (100 mL) of beverage was computed to be ₹ 4.52. The tamarind effervescent tablets were thus economical, convenient to use and store. The commercialization of this technology may open new avenues for enhancing tamarind production and consumption, thereby benefitting all related stake holders in tamarind business, including farmers, industries, handlers and consumers

    Standardization of microwave assisted process for preparation of roasted horsegram snack
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2022-04) Mohd Nazim; Sabbu Sangita
    Horsegram represents a major source of protein and dietary fibre in many developing countries. In the industrialized countries, horsegram is gradually being viewed as an alternative source of protein. These days consumers tend to look for food supplies that are ready to eat due to their modern life style, busy schedules and require diet food. Convenient food prepared from whole seeds of horsegram is also not available or commercialized till today. The present investigation was thus aimed to develop a microwave assisted process for ready-to-eat horsegram snack. For optimization of process condition to make horsegram snack from non-germinated and germinated seeds of horsegram, 3-level factorial design was used. For the preparation of snack from non germinated seeds, 2 salts i.e. sodium chloride (NaCl) and sodium bicarbonate (NaHCO3) in a ratio of 1:1 at 3 different levels (1, 2 and 3 %) with 3 levels of temperature (30, 45 and 60° C) were used for soaking experiments. For the development of germinated horsegram snack 3 different levels of temperature (30, 35 and 40° C) with 3 different time periods (12, 18 and 24 hours) were utilized for germination of horsegram seeds. After analysis,1 % of salt level (NaCl:NaHCO3) and 51.27 °C temperature was found to be optimum for soaking condition while horsegram seeds germinated at 34.48° C temperature for 24 hours produced the ideal quality of horsegram snack. After optimization, both the samples were subjected to different microwave roasting conditions (11, 12, 13, 14 and 15 minutes for 350 Watt and 4, 5, 6, 7, and 8 minutes for 500 Watt) and observation revealed that 500 Watt power under microwave roasting for 6 min was the ideal roasting condition for the development of non-germinated horsegram snack while 500 Watt power and 5 minutes of roasting time were suitable for the production of germinated horsegram snack. In a comparative study of horsegram snack among both germinated and non-germinated horsegram snack it was found that germinated horsegram snack contained more nutrition in terms of protein, fibre and total minerals. It was also observed that germinated horsegram had less antinutritional component (oxalate and tannin) as compared to non germinated horsegram snack. Horsegram can be utilized for value addition and development of various convenient and healthy products. This product can be further recommended for commercialization.

    Standardization of process for customised instant tea
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-12) Barthwal, Riya; Sharma, S.K.
    India is one of the largest producers as well as consumers of tea {Camellia sinensis (L.) O. Kuntze} in the world. Since it is the cheapest of all the beverages available, it has become a regular part of our living, having economic, therapeutic and social importance. Having more than 4000 bioactive components, with polyphenols accounting for one-third of them, tea is known for its various health benefits. There is no standard and universal way to make tea, mostly tea leaves are brewed in hot water before adding other ingredients. Considering the busy lifestyles and hectic schedules of people the brewing time of less than 5 min is also sometimes very long. Further, cleaning utensils used for tea preparation and its straining etc. are much more cumbersome. Also, handling and disposal of wastes generated from tea leaves, tea bags etc. are a mess to handle and discard. The present investigation was thus aimed to develop a hot water soluble liquid tea concentrate which is complete soluble without leaving any residues / turbid matter and which provides option of in-the-cup customization of tea aroma and tea pigments, alongwith other ingredients in liquid form. Tea aroma concentrate (TAC) was obtained by hydro-distillation of commercial black tea with a water : tea ratio of 118:10 and collection of 20 % of the aroma distillate. The non-volatile total soluble solids concentrate (TSSC) were obtained by removal of excess water from leftover of TAC distillation by vacuum evaporation and subsequent extraction of soluble solids with 40 % ethanol and making the concentrate ethanol free under vacuum. For in-the-cup customization of tea, 0.25 mL (5 drops) of TAC and 0.5 mL (10 drops) of TSSC gave a beverage of excellent quality when added to 80 mL of boiling hot water with cardamom oil (0.05 mL), tulsi oil (0.05 mL), ginger juice (1.5 mL), sugar cubes (2) and milk (10 mL).The cost of tea portion excluding all other ingredients, w.r.t. the optimized product, (₹ 0.85 per cup) was only marginally higher than that (₹ 0.75 per cup) for commercially available loose black tea. Upscaling of the technology can be done for further cost reduction. Improvement in packaging and product delivery studies may be undertaken in future to open new avenues for commercialization of in-the-cup customized teas with all liquid ingredients for higher convenience.

    Process optimization for development of instant-chickpea-recepie mix
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-09) Badola, Rahul; Sabbu Sangita
    The present investigation was carried out in the Department of Food Science & Technology, G.B. Pant University of Agric. & Tech., Pantnagar, U.S. Nagar (Uttarakhand) during the year 2018-19. The objective of this study was to develop instant chickpea by using Response Surface Methodology (RSM). For optimization of process conditions to make instant chickpea from small as well as large seeded varieties, Central Composite Rotatable Design was used. The process to make instant chickpea involved soaking, cooking and drying. Seeds of both the varieties were soaked in tap water containing 0.5, 1.0 and 1.5 % of each salt Sodium chloride (NaCl), sodium bicarbonate (NaHCO3), and ammonium carbonate ((NH4)2CO3)) at three levels of temperature (30, 45 and 60 °C) followed by washing, cooking and drying for the instantization process. Soaking of small chickpea in salt solution containing 0.59 % NaCl, 0.85 % NaHCO3, and 0.82 % (NH4)2CO3 at 49.81 °C temperature for 217.58 min was found an optimum treatment to produce instant chickpea having cooking time of only 10.27 min. Similarly, soaking of large chickpea in salt solution having 1.07 % NaCl, 0.79 % NaHCO3, and 0.70 % (NH4)2CO3 at 46.53 °C temperature for 270.61 min was optimum treatment to produce instant chickpea with cooking time of only 12.88 min. Results showed that bulk density, true density, 1000 kernel weight, porosity and colour difference were reduced significantly at 5 % level for instant chickpea as compared to raw chickpea for both the verities except length and width. Changes in content of moisture, fat, calcium and iron were non-significant due to preparation of instant chickpea from both verities. In small seeded instant chickpea protein, ash and phosphorus content were reduced but carbohydrate content was increased (P ≤ 0.01). In large seeded instant chickpea ash and phosphorus content were decreased whereas protein and carbohydrate contents showed insignificant difference as compared to raw chickpea. Fibre content in both the verities was increased significantly (P ≤ 0.01) after making instant chickpea. Curry powder for instant chickpea was also developed containing tomato, onion, ginger and garlic powder with spices, corn flour and oil. Ready-to-serve chickpea can be prepared by adding 100 g of instant chickpea and 63.4 g curry powder in 400 ml of boiling water followed by cooking for 11 min for small chickpea and 13 min for large chickpea.

    Enzymatic clarification of sugarcane juice
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-01) Basu, Lasattanu; Kumbhar, B.K.
    Effects of parameters namely, enzyme concentration (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 %), incubation period (1, 1.5 and 2 h), centrifugation speed (4000, 4500 and 5000 RPM) and time of centrifugation (5, 7.5 and 10 min) on enzymatic clarification of sugarcane juice were studied. Boiling was incorporated as a pretreatment which reduced the amount of impurities in the juice. Soluble solids, total solids, optical density and percent transmittance were measured and used for determining the efficacy of enzymatic clarification of sugarcane juice. The type of pan (iron and stainless steel) used for boiling was also considered. Full factorial design was used for selecting the levels of parameters in the experiment. Full second order polynomial and best fit equations were developed to predict various responses and to study individual and interactive effects of parameters on the responses. The clarification efficiency ranged between 39.97–70.41 % and 57.09–85.54 % for non-enzymatic and enzymatic clarification of sugarcane juice in iron pan, respectively. Correspondingly, it varied between 38.60–72.08 % and 56.14–85.56 % in case of stainless steel pan. Optical density varied between 1.02 and 0.56 for non-enzymatic clarification and 0.95–0.24 for enzymatic clarification of sugarcane juice in iron pan. It was 0.93–0.48 and 0.79–0.17 for stainless steel, respectively. Minimum percent transmittance was 7 and maximum was 28 for non-enzymatic treatment in iron pan and correspondingly it was 11 and 58 for enzymatic clarification. In stainless steel pan experimentation, it varied from 12-33 and 16-68, for non-enzymatic and enzymatic clarification, respectively. Enzyme concentration had highly significant effect on clarification efficiency followed by centrifugation speed, incubation period and time of centrifugation in that order. However, centrifugation speed had highly significant effect on optical density and percent transmittance followed by enzyme concentration and time of centrifugation. Incubation period did not affect these responses. It was found that the type of pan did not affect the clarification efficiency and optical density.

    Development of bengal gram (Cicer arietinum L.) based wari and its fermentation kinetics
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-01) Mallik, Arpita; Agrawal, Y.C.
    ‘WARI’ is a legume based traditional fermented food of northern India. It is manufactured from Urd (black gram) or Moong (Green gram) dhal according to the traditional, technologically less advanced methods, and is produced at home or cottage industry level. Partial fermentation could take place naturally during sun drying. The Bengal gram dhal (Cicer arietinum L.), commonly known as ‘chana-dhal’, was not being used in WARI making and no studies have been reported. ‘Chana-dhal’ is cheaper than Urd and Moong dhal and could therefore be a better raw material for WARI if acceptable to consumer. The objectives of this research, therefore, were to develop a process for Bengal gram based WARI in view of organoleptic properties, to investigate the effect of fermentation temperature, and to study its fermentation kinetics. WARI were prepared from Bengal gram and Black gram dhal blends (100:0, 80:20 and 60:40) following the traditional procedure without extra fermentation and with 12 hr pre-drying fermentation at room temperature. The quality determinants of WARI were rehydration ratio and sensory characteristics in its two forms – dehydrated and rehydrated ready-to-serve. The sensory characteristics for dehydrated WARI were – color, appearance, odor and acceptability to purchase and for rehydrated ready-to-serve WARI were – color, appearance, taste, flavor and overall acceptability. The sensory data were analysed statistically using one-way Analysis of Variance. The effect of fermentation was then studied at room temperature, 30, 35 and 40°C temperature. Fermentation kinetics was studied in respect of the changes in fermented volumes with time and kinetics model was developed. It was observed that Bengal gram based WARI were possible to be made with consumer acceptance. The statistical analysis revealed that these could be made from Bengal gram dhal or its blends with Black gram dhal provided the batter was fermented before the drying of WARI. The process recommended for better quality WARI however was to make WARI from 100% Bengal gram dhal using pre-drying fermentation at 35 or 40°C for 8 or 3.5 hr respectively at which time, the corresponding batter volume expanded to about 2.3-2.4 times the original. The flavor and overall acceptability of WARI in its rehydrated ready-to-serve form and the rehydration ratio was the only quality determinants, which significantly influenced by different process conditions at 5% probability level. If the fermentation were to be carried out at room temperature, it should be initiated in the morning during warmer days and could be initiated at the night on hot summer days, so that the room temperature is 29°C or above. The maximum fermented volumes were about 1.8-2.4 times the original for chana dhal batter and for its blend with 20% Black gram, these were about 2.2-2.6 times depending upon the fermentation temperature. The fermentation kinetics of WARI batter represented by the changes in fermented volume followed the normal growth cycle pattern of microorganisms. The model for the fermentation kinetics of the WARI was developed in the form of growth kinetics of microorganisms during exponential phase of growth: V = V0 e μt where, V = volume of WARI batter at any time t, ml; V0 = initial volume of WARI batter, ml; μ = Specific Fermentation Rate, (1/hr), Table 4.24; t = time of fermentation, hr, when lag phase is negligible or nil; or t = (time of fermentation – duration of lag phase), when lag phase duration is long. The values of model parameter μ were determined from the fermented volume change data and are reported in Table 4.24. The model predicted the fermentation kinetics very well.
