ThesisItem Open Access REFINEMENT OF TECHNOLOGY FOR PRODUCTION OF LACTIC ACID FERMENTED VEGETABLE PRODUCTS(2013) SARITA, DEVI; JOSHI, V.K.ABSTRACT The present Investigations entitled “Refinement of Technology for production of Lactic acid fermented vegetable products” were carried out in the Department of Food Science and Technology, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the year 2011-12. The present findings revealed that that lactic acid fermented pulp can be successfully utilized in the preparation of different products. In case of carrot and radish RTS and appetizer, treatment with 50 % fermented pulp + 50 % unfermented pulp gave the best results for physico-chemical as well as sensory characteristics. In case of carrot and radish chutney, treatment having 50 % fermented pulp + 50 % unfermented pulp gave the best results respectively. For the best sensory characteristics treatment T1R4Ca in carrot and T1R3Ra in radish gave the highest scores whereas, in case of pickle- in- brine treatment T2R3C in carrot and T2R3R in radish gave the highest scores. During the passage of storage period, there was a slight decrease in all the physico-chemical and sensory characteristics except pH and browning. Among the different packaging materials and storage conditions, the product stored in glass jars and refrigerated conditions showed less change in all the physico-chemical and sensory characteristics than the product stored in the plastic jar and ambient conditions, respectively during the 6 month storage. Fermented carrot had the higher cost of production (Rs. 50.34) than the fermented radish of (Rs. 48.26). The cost per unit bottle for radish based fermented ready-to-serve drink and appetizer were found to be the lower Rs.8.97 and Rs.13.56/200 ml bottle than those of carrot respectively. Thus, the developed technology can be commercially explored at industry level for production of the fermented processed products with probiotic effect.ThesisItem Open Access STATISTICAL INVESTIGATION ON PLANTING DENSITY AND FREQUENCY OF FOLIAR NITROGEN APPLICATION IN Gladiolus hybrida(UHF,NAUNI, 2018-01) SARITA, DEVI; MAHAJAN, P.K.ABSTRACT Secondary data for this investigation was taken from the department of “Floriculture and Landscape Architecture” for the accomplishment of objectives of this investigation which were to assess the relative contribution of growth and flowering characteristics using multivariate techniques and to identify the stable planting density and frequency of foliar nitrogen application using probability models. Multivariate techniques were used to assess the relative contribution of growth and flowering characteristics. Two principal components were extracted by applying principal component analysis which accounted for 82.489% of total variation of the original variables and two out of eleven factors were extracted by applying factor analysis which explained 79.203% of total variation of the original variables. Two stability models i.e. Finlay & Wilkinson and Eberhart & Russell were applied to identify the stable planting density and frequency of foliar nitrogen application for the four characters (number of corms per square meter, weight of corms per square meter, number of cormels per plant, weight of cormels per plant) out of eleven for which variances due to treatment (T), season(S), treatment × season (T × S) interaction were found to be significant. Both the stability models revealed that that treatment combinations N1D2 and N2D2 were stable for number of corms per m2, treatment combinations N1D1, N1D2, N1D3, N2D1, N2D2, N2D3, N3D2 and N3D3 were stable for weight of corms per m2, treatment combination N1D3 was stable for number of cormels/plant and treatment combination N2D1 was stable for weight of cormels/plant, with respect to foliar nitrogen application and plant density.
