Feasibility Of Expanding The Market For Fish And Processed Fruit/Vegetables In Moab/Green River, Deevon Bailey, Yasmin Adam

Economic Research Institute Study Papers

The potential market size for a fresh fruit and vegetable market was estimated based on a consumer survey of visitors to Moab and Green River during the first week of September 1995. It is estimated that local growers could sell approximately $500,000 worth of locally growth produce between June and October each year. A jam/jelly plant would likely be a profitable venture if the plant is built in Green River and the products are marketed in both Moab and Green River.

Luminescence Techniques To Identify The Treatment Of Foods By Ionizing Radiation, G. A. Schreiber, B. Ziegelmann, G. Quitzsch, N. Helle, K. W. Bogl

Food Structure

About a decade ago two luminescence techniques, thermoluminescence (TL) and chemiluminescence (CL), were first described as methods for the detection of irradiated spices. It has now been established that the CL method can be used to screen only certain foodstuffs for irradiation. The TL method, instead, has been developed for clear identification of foods irradiated with at least 1 kGy and contaminated by minerals. The method is therefore suitable for a wide range of foodstuffs and it has been applied by laboratories for routine control. The latest findings prove that even irradiation with very low doses used to inhibit the …

The Cellular Structure Of Selected Apple Varieties, K. G. Lapsley, F. E. Escher, E. Hoehn

Food Structure

Apple cultivars (Sauergrauech, Klarapfel, James Grieve, Granny Smith, Mcintosh, Robinette) which had different textures based on sensory and instrumental analysis (particularly in firmness and mealiness) were examined by conventional scanning electron microscopy (SEM), cold-stage SEM (cryoSEM) and confocal scanning laser microscopy (CSLM) using various preparative procedures. Advantages, lim itations and artifacts of each technique are discussed.

SEM with glutaraldehyde-fixation and criticalpoint- drying produced minimal tissue distortion and the fracture pattern and appearance of mealy versus non mealy tissue was different. Freeze-drying unfixed tissue caused cell collapse and firm versus soft varieties could not be differentiated. Freeze-fracturing and cryoSEM of apple …

Scanning Electron Microscopy Structure And Firmness Of Papain Treated Apple Slices, Yaguang Luo, Max E. Patterson, Barry G. Swanson

Food Structure

'Mcintosh' apple (Malus domesrica Borkh.) slices were treated with papain. Textural changes were recorded with an Instron Universal Testing Machine. Structural changes and distribution of microorganisms in apple tissues after treatment were observed with a scanning electron microscope (SEM). Apple slices submerg ed in a 1% papain solution were significantly firmer than apple slices submerged in the distilled water control for a 24 hour period (P < 0.05). Three and four days after slicing , a significantly smaller decay index was observed on the apple slices submerged in papain solution than on the control slices. Under SEM, less severe cell wall breakdown was observed on the apple tissues treated with papain than on apple tissues without treatment. Less spores were also observed on the papain treated apple slices than apple slices without treatment. Apple tissues treated with papain solution and distilled water also demonstrated noticeable st ru ctural differences. The apple tissues treated with papain solution for 18 hours retained the original cell structure while the cells in the apple tissues treated with distilled water collapsed.

Control And Evaluation Of Big Game Browsing Damage To Commercial Fruit Orchards, William E. Stone

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diversionary feeding, artificial feeding designed to divert animals away from areas where they might cause property damage, was tested for efficacy in reducing fruit orchard browsing by big game animals during two consecutive winters in Utah. Strategically placed attractive feedstuffs lured deer to feed stations and reduced fruit-bud browsing (1st year, P < 0.07; 2nd year, P < 0.01). Blossom and apple numbers were greater (P < 0.05) on trees in the feed (treatment) orchard than in the no feed (control) orchard in each year. However, higher (P < 0.05) apple production on trees where browsing was excluded in the treatment orchards compared to the control orchards indicated that intercept feeding did not increase crop production. Tree periodicity and other factors affecting apple production masked the effect of diversionary feeding on crop yield.

Two independent browsing damage assessment methods, a paired-tree technique and a harvest-inflation technique, predicted that the ratio of apples lost per browsed bud was 0.158 and 0.082, respectively. However, the values of the ratio varied widely with each method of estimation. Browsing damage differed ( …

The Use Of Foliar Applied Zinc Compounds In Correcting Zinc Deficiency In Fruit Crops, Lynn F. Hall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effectiveness of two chelated zinc compounds in correcting zinc deficiencies was studied. Soil and foliar treatments were made to study possible residual zinc carry-over from one season to the next. Foliar treatments at various rates were applied to raise plant tissue zinc levels above deficiency levels. It was found that none of the treatments studied resulted in any substantial carry-over of zinc to the following year. All of the foliar zinc treatments resulted in an increase in leaf zinc content in all of the varieties of fruit studied. The level of zinc in the treated trees increased in proportion …

Anthocyanins Of Fresh And Stored Freeze-Dried Sour Cherries In Compressed Form, Suwan Potewiratananond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Anthocyanin pigments of sour cherry (prunus cerasus L., cultivar Montmorency) fruit were studied by spectrophotometry, paper and two-dimensional thin layer chromatography and disc electrophoretic method. Mature and wholesome fresh sour cherries and freeze-dried compressed sour cherries stored at 70 F and 100 F for 6 months were used.

A total of seven anthocyanin pigments were observed in both paper and thin layer chromatograms of the fresh and freeze-dried compressed samples stored for O month whereas the freeze-dried compressed samples stored at 70 F and 100 F for 6 months showed the retention of three to six pigments. All of …

Insect Pollinators Frequenting Strawberry Blossoms And The Effect Of Honey Bees On Yield And Fruit Quality, William P. Nye, J. Lamar Anderson

All PIRU Publications

Open plots of strawbery (Fragaria sp.) or plots caged with colonies of honey bees (Apis melilfera L.) produced less malformed fruit than plots screened to exclude large insects. Bees and large Diptera, mostly drone flies (Eristalis spp.), were the most numerous visitors to the strawberry blossoms. A list of insects including 108 species representing 35 families frequenting strawberry blossoms in Utah was compiled. The most efficient pollinators were Apis mellifera, Halictus ligatus Say, and Eristalis spp.

Isolation, Identification, And Comparison Of The Volatiles Of Peach (Prunus Persica L., Cultivar, Gleason Early Elberta) Fruit As Related To Harvest Maturity And Artificial Ripening, Joseph Yungsheng Do

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Volatiles of peach (Prunus persica L., cultivar, Gleason Early Elberta) fruit were studied by gas-liquid chromatography, thin-layer chromatography, and infrared spectrometry. Hard mature, firm mature, soft mature, tree ripe, and artificially ripened hard mature fruit obtained from four seasons, 1964 to 1967, were used. A total of 86 peaks were observed in the chromatogram of the tree ripe peach volatiles. Major components of the volatiles identified were mainly esters, gamma and delta lactones, aldehydes, alcohols, and terpenes. In general, concentration of the volatile components were found to increase with the maturity of the fruit. However, that of the artificially …

Comparative Effects Of Dehydration Processes On Physico-Chemical Changes In Fruits, Chang Yong Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Drying with the help of sun and wind is one of the oldest methods of food preservation known to man, but artificial drying, or dehydration, has been developed and used extensively only during the last two decades. The problem in dehydration is that the water content must be decreased sufficiently to maintain the stability of the product by retarding the rates of deteriorative biochemical, microbiological, and enzymatic reactions during subsequent storage. At the same time irreversible changes should not be brought about.

Investigations Into Flavor Chemistry With Special Reference To Synthesis Of Volatiles In Developing Tomato Fruit (Lycopersicon Esculentum Mill.) Under Field And Glass Greenhouse Growing Conditions, K. B. Dalal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The common tomato of our garden belongs to the natural order Solanaceae and the genus Lycopersicum. The name from lykos, a wolf, and persica a peach, is given to it because of the supposed aphrodisiacal qualities, and the beauty of the fruit. By culture and use it is a vegetable, botanically it is a fruit and among the fruits, it is a berry being indehiscent, pulpy, with one or more seeds that are not stones.

Thermal Degradation Of Pigments And Relative Biochemical Changes In Cherries And Apricots, K. B. Dalal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The extent and nature of biochemical changes that take place in canned fruits during storage temperatures above freezing have been reviewed and discussed by Pederson, et al. (1947). These changes include loss in nutritive value, e.g. ascorbic acid, thiamine (Brenner, et al., 1948) and deterioration of color (Tressler, et al., 1955). Bauernfeind (1953) reported that canned peaches, apricots, and sweet cherries, after a few months of storage at 70°F, frequently undergo changes such as destruction of anthocyanin and carotenoid pigments with the subsequent formation of brown colored compounds. Darkening of fruit-color eventually results in their unacceptability at …

Bulletin No. 356 - Consumer Demand For Fruit: Salt Lake City, Utah, 1948-1949, Ellis W. Lamborn, Roice H. Anderson

UAES Bulletins

In a free enterprise economy where production and consumption are adjusted through the medium of prices, consumers direct the kinds and amounts of production through their choices in the market. The problems of production and marketing of any product cannot be effectively solved without studying the wishes and actions of consumers.

To ignore the decisions of consumers is economic suicide. No one can long continue to produce who does not find buyers for his product. The producers who give the consumers what they want, in the form and at the time they want it, and at a price they are …

Bulletin No. 279 - The Fruit Tree Situation In Utah, A. L. Wilson, A. L. Stark

UAES Bulletins

The fruit industry in Utah is not large when compared with the total production of the United States. The year 1935 was a favorable fruit season for Utah and yet the state produced only 0.54 percent of the United States' apple crop, 1.30 percent of the peach crop, 0.31 percent of the pears, and 3.72 percent of all cherries. Utah does, however, produce between 10 and 15 percent of all sweet cherries. Even though the Utah fruit industry represents such a small part of the national industry, a great many people of the state are dependent upon it, either wholly …

Circular No. 84 - Building Young Deciduous Fruit Trees, Francis M. Coe

UAES Circulars

The modern fruit tree in a commercial orchard, to survive in present-day competition, must bear heavy crops. The mechanical strength which determines whether it can hold its heavy load successfully or whether it will be broken down and become a liability to its owner is determined to a large extent by the training it has received the first two or three years after planting.

Bulletin No. 124 - Fruit Variety Tests On The Southern Utah Experiment Farm, A. B. Ballantyne

UAES Bulletins

Since the material contained in the following report of the variety tests on the Southern Utah Experiment Farm was mainly accumulated under plans outlined before the farm was made part of the Utah Experiment Station, it may be well in this connection to give a brief history of its location, management, and a survey of its situation. It was established by an act of the State Legislature approved March 21, 1899, and the site was chosen the following July by a committee appointed by Governor Heber M. Wells. The area selected consists of forty acres located in the southeastern portion …

Circular No. 13 - Fruit For Exhibition, Leon D. Batchelor

UAES Circulars

The basis of a good fruit exhibit is necessarily good cultural conditions to produce good fruit. Then it depends on the exhibitor's ability to select his best fruit. Do not wait until the crop is picked to select show specimens. The successful exhibitor makes his prize selections in the orchard while the fruit i still on the tree. By viewing the fruit as it hangs naturally on the tree, and by carefully surveying the different trees in the orchard a good comparison of a large quantity of fruit can be made. The prize fruit is generally on the outermost branches, …
