ThesisItem Open Access DEVELOPMENT OF VALUE ADDED PRODUCTS FROM BOX MYRTLE (Myrica nagi)(UHF,NAUNI, 2014) THAKUR, ABHIMANYU; THAKUR, N.S.ABSTRACT The present studies entitled, “Development of value added products from box myrtle (Myrica nagi)” were conducted during 2012-2014 in the department of Food Science and Technology, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni-173230, Solan (H.P.). Box myrtle (Myrica nagi) is one of the unique wild fruit which has got great commercial importance because of its high TSS and high total phenol content. The fruit has also got good antioxidant and medicinal properties. Therefore, investigations were conducted to develop value added products from box myrtle. The best method for juice extraction was found to be pulper (brush type). Best value added products were prepared viz; drink by keeping juice 14 per cent, TSS 12 o B and 0.30 per cent acidity; squash was by keeping 40 per cent juice, 40 o B TSS and 1.20 per cent acidity; appetizer by keeping 35 per cent juice, 40 o B TSS and 1.20 per cent acidity; syrup by keeping 35 per cent juice, 65 o B TSS and 1.50 per cent acidity and jelly by keeping 55 per cent juice, 45 per cent sugar and 0.72 per cent acidity. Although, all the products after packing in glass and PET containers could be stored successfully in refrigerated storage for six months. However, quality of the products packed in glass materials was retained better in refrigerated storage conditions as compared to the polyethylene teraphthalate (PET) stored in ambient storage conditions. The cost of the products prepared from box myrtle was comparable to the cost of the similar products in the market. Hence, box myrtle can successfully be utilized for the preparation of variety of good quality and nutritionally enriched processed products.ThesisItem Open Access “Development and Evaluation of Mushroom Fortified Indian Bread”(UHF,NAUNI, 2014) PATYAL, SUCHETA; VAIDYA, DEVINAABSTRACT The present studies entitled, “Development and evaluation of mushroom fortified Indian bread” were conducted during 2012-14 in the department of Food Science and Technology, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni-173 230, Solan (HP). Bread is one of the most widely consumed food product in the world. It is a cereal product from wheat flour that is naturally low in protein and nutritionally not a balanced diet because it is low in lysine, an essential amino acid. Mushroom is a good source of quality protein so, mushroom will complement with wheat flour to produce nutritionally balanced high quality flour, bread and chapatti. On dry weight basis this mushroom contains 35.6 percent crude protein, 2.2 per cent crude fat, 8.7 per cent crude fiber and 9.8 per cent ash. Therefore, present study is mainly concentrated to utilize Pleurotus mushroom for fortification of wheat flour for development of bread and chapatti to enrich their functional properties. Different concentration of mushroom flour was fortified with wheat flour and evaluated for various quality characteristics. However, 10 percent mushroom flour fortification was found better on the basis of physico chemical, sensory and rheological properties and used as fortified flour for development of bread and chapatti. The storage of bread (cling foil for 12 days) and chapatti (HDPE vacuum pack for 44 days) under refrigerated condition was found better to retain the freshnessas well as nutritional quality of the developed products.ThesisItem Open Access UTILIZATION OF WILD PEAR (Pyrus serotinaRehd) FOR PRODUCT DEVELOPMENT(UHF,NAUNI, 2014) LUCKY, DEVI; DHIMAN, ANJU K.ABSTRACT The present investigation entitled, “Utilization of wild pear (Pyrus serotina Rehd) for product development”was conducted during the year 2011-2012 in the department of Food Science and Technology, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP). However, the fruits of wild pearare found in abundance throughout the mid hill regions but, no attempt so far has been made to utilize the crop for processing and developing value added products. The study, therefore, was conducted to develop value added products from wild pear and evaluate their quality and storage stability. The wild pear with 70.80 per cent moisture content was found to be a good source of vitamin C (14.49 mg/100 g), total phenols (149.55 mg/100 g), βcarotene (4.72 µg/100 g), pectin (1.22%), crude protein (1.64%) and crude fibre (1.54%). The recipes and methods of preparation of pickle, preserve and osmotically dehydrated wild pear halves have been standardized. Among different recipes for pickle, the highest ratings were received by Recipe II (65 0 Brix) and was selected for further studies. The best results for osmotic dehydration of fruits were obtained by dipping the fruit halves in 70 0 Brix sugar syrup for 24 hours after pretreatment. During storage the pickle prepared by using fruit slices treated with water blanching for 2.5 minutes + 1.0 per cent citric acid dip for 20 minutes was rated as the best. While preserves prepared from fruits by water blanching for 9 minutes + 1.0 per cent citric acid dip for 30 minutes (with peel) and water blanching for 8 minutes + 1.0 per cent citric acid dip for 30 minutes (without peel) were adjudged superior to rest of the treatments. The fruit halves when water blanched for five minutes followed by 1.0 per cent citric acid dip for 20 minutes for osmotic dehydration recorded the highest scores. The study revealed that all the products can be safely stored under ambient temperature for a period of more thansix months with admissible changes in chemical and sensory attributes. Hence, it is concluded that wild pear can be successfully utilized for the preparation of a variety of good quality and nutritious processed products of remunerative price.ThesisItem Open Access PREPARATION AND EVALUATION OF LOW ALCOHOLIC BITTER GOURD BASED WINE(UHF,NAUNI, 2014) NAVEEN, KUMAR; JOSHI, V.K.ABSTRACT Bitter gourd (Momordica charantia) a member of the cucurbitaceae family, is known asbitter melon, bitter gourd, balsam pear and karela. It grows in tropical areas of the Amazon, East Africa, Asia, India and South America. Momordica charantia is traditionally used as a medicine. Bitter gourd is a popular vegetable among gourds, though due to its peculiar taste and flavour, it may not be liked by many of the persons. Nevertheless, it has high nutritive value among different gourds. It is a rich source of ascorbic acidbut is a fair source of protein, minerals and dietary fibers. Thefruit has several medicinal uses in the traditional methods of medicine. Fruits and seeds of bitter gourd are traditionally used as a medicinal herb as anti- HIV, anti-ulcer, anti-inflammatory, antileukemic, anti-microbial, anti-diabetic and anti-tumer. Recently, the antidiabetic properties of the fruit are under intensive investigation. Preservation by different methods such as steepping preservation, sun drying and dehydration has been carried out, but very little work has been done to prepare beverage/ juice in India. Being a highly medicinal crop, the vegetable can be used to prepare different processed products including alcoholic beverages. Preparation of alcoholic beverages including wine is one of the options available. Standardization of bitter gourd juice extraction was carried out with enzymatic maceration and by using water dilutions. On the basis of physico-chemical characteristics, enzymatic treatment having pectin esterase 0.5% concentration for 4hrs was rated as the best. Standardization of apple/grape juice concentrations, DAHP concentrations and concentrations of inoculum size was done by applying central composite design (CCD) of RSM for preparation of bitter gourd based wine. Bitter gourd based wine was prepared by using optimized conditions from response surface methodology experiment. On the basis of physico-chemical and sensory characteristics, runs having 40% apple/grape juice concentration, 0.15 % DAHP and 2.5 % inoculum level were rated as the best. After fermentation, bitter gourd based wine was treated with different wood chips i.e. Acacia spp., Bombaxspp. and Quercusspp. These wines were matured for a period of three months and were evaluated for physico-chemical and sensory quality characteristics. Out of three wood chips, Quercus spp. treated wine was preferred by the judges, followed byAcacia spp. and thenBombax spp. The product being low alcoholic need pasteurization at 62 0 C for 20 min. keeping a head space of 2.5 cm in a bottle. Bitter gourd wine so prepared was holds promise to make a patable yetretaining the product with medicinal properties.ThesisItem Open Access PRODUCTION AND EVALUATION OF BIOCOLOUR FROM MONASCUS USING APPLE POMACE(UHF,NAUNI, 2014) SHARMA, SANGEETA; JOSHI, V.K.ABSTRACT Colour plays a crucial role in the food we eat as the consumers want to see their food looking natural, appetising and enticing. To minimizing the carcinogenic effect of synthetic colours the demand for natural source of colours is increasing. Apple pomace – a left over residue after juice extraction containing peel, seed and remaining solid parts is a rich source of carbohydrates, dietary fibres, minerals, and vitamin C can be utilized as a substrate for production of colour from microorganisms. Earlier attempts have been made toutilize apple pomace as a base for the production of biocolour using Rhodotorula, Micrococcus, Chromobacterand Sarcina. Monascus purpureus a fungus belonging to family Monascacese is a colour producing microorganism. It mainly produces 3 types of colours, yellow, orange and red.Monascus are traditionally used in oriental countries, originally in China and Thailand, to prepare fermented rice with strong redcolour, which finds several applications ranging from conferring colourto products as wine, cheese and meat, to medicinaluses and as a meat preservative. Monascus purpureus is normally cultivated on cooked rice to produce a range of metabolite, statin viz. Lovastatin, monacolins J, pravastatin and mevastatin. Lovastatin (Monacolin K) has cholesterol lowering properties. Monascus purpureusis cultivated on various media but there is no report of using apple pomace as a substrate for Monascus purpureus. Media was Standardize for Monascus purpureuswith respect to substrates, carbon, nitrogen and mineral sources. On the basis of this experiment it was found that apple pomace can be utilized for colour production from Monascuswhen it is supplemented with rice. With respect to yield ofcolour, glucosamine and monacolin K treatment having apple pomace supplemented with rice (4.8%), glucose (4%), monosodium glutamate (0.2g/l) and magnesium sulphate was found as best. Thin layer chromatographic identification of colour was carried out and it was observed that the colour mainly has two pigments monascin and monascorubramine. Evaluation of colour was carried with tintometer which reveal that maximum red and yellow units are present in the same treatment having apple pomace supplemented with rice, glucose, mcdonosodium glutamate and magnesium sulphate. Optimization of growth conditions using response surface methodology (RSM) was carried out and optimum pH value of 6.25, 30 0 C temperature and time interval of 12 days was foundbest for production of colour, glucosamine and monacolin K in apple pomacesupplemented with rice medium. Chemical conversion of the colour to water soluble colour reveals that maximum conversion was obtained with amino glutamic acid (72%). Pigment so produce can be utilized in food products to minimize the harmful effects of synthetic colour and apple pomace can be utilized for the production of such colour.ThesisItem Open Access STANDARDIZATION OF METHOD FOR SEPARATION OF SEEDS FROM APPLE FOR RAISING APPLE ROOTSTOCKS(UHF,NAUNI, 2013) SATISH, KUMAR; SHARMA, P.C.ABSTRACT Process protocol for mechanical removal of fruit core from apple fruits and separation of seeds from fruit core for raising apple rootstocks was standardized. Fruit maturity characters viz.TSS, firmness, specific gravity etc. were analyzedto ensure use of fruits of seven different cultivars of apple of optimum maturity with good seed health. Fruit dimensions viz. horizontal and vertical fruit diameter, core length as well as core diameter were evaluated for characterizing mechanical device for coring of apple fruits. On the basis of fruit and core dimensions, mechanical corer consisting of coring tube internal diameter 22.1 mm, fruit holding cup and plunger device for moving the coring tube was developed. The coring efficiency of the mechanical apple corer (73.4 kg/h) was found about 5.12 times higher as compared to manual coring method (14.3 kg/h). For softening of fruit core prior to seed separation the suitability of enzymatic pre treatment of pectinase and amylase enzymes was evaluated. Mean core diameter after pectinase enzyme treatment was reduced from 22.1 mm to 17.9- 8.5 mm within a concentration range of 0.1- 1.0 per cent within 24-72 hours indicating good coresoftening. Use of amylase enzyme treatment on the other hand caused only 31.7 per cent reduction in core diameter of apple core. Thus, pre treatment of fruit core by using pectinase (1 %) enzyme for 24 hours was optimized. The softened fruit core was found suitable for passing through the mechanical tomato seed separator for separation of seeds. Various parameters of the mechanical seed separator viz.feed rate of the core, seed damage, seed loss and seed extraction efficiency were analyzed. The average seed extraction rate in mechanical seed separator (311.53 g/h) was found 18 times higher as compared to manual seed separation method (17.28 g/h) with negligible seed damage. The germination potential of the seeds separated through mechanical seed separator was found to be 89.9 % as compared to only 65.3 % germination recorded in seeds separated from apple pomace left after juice extraction. Thus, method of separation of apple seeds canbe adopted by the orchardists as well as fruit processing units to serve the apple industry for raising rootstocks.ThesisItem Open Access Studies on ethylene management and storage of packed apples(malus domestica bork.)cv.red delicious(UHF,NAUNI,SOLAN, 1991) CHANDER, BAL VIPAN; CHOPRA, S.K.ThesisItem Open Access Evaluation of post harvest handling methods for carnation and gladiolus cut flowers(UHF,NAUNI,SOLAN, 2000) BHAT, ANJU; THRIPATHI, S.N.ThesisItem Open Access Evaluation studies on commercial varieties and promising hybrids of tomato grain in H P for processing(UHF,NAUNI,SOLAN, 1993) THAKUR, NARAYAN SINGH; KAUSHAL, B.B.
