Isolation And Characterization Of Atriplex Hortensis And Sweet Chenopodium Quinoa Starches, K. H. Wright, K. C. Huber, Daniel J. Fairbanks, C. S. Huber

Faculty Publications

Starches from garden orach (Atriplex hortensis) and sweet quinoa (Chenopodium quinoa Willd. "Surumi") seeds were isolated, examined for compositional characteristics, and compared with bitter quinoa (Cheno-podium quinoa Willd.) starch. Garden orach and sweet quinoa seeds were similar in fat and ash contents, while garden orach seeds contained 10% more protein. Starches were isolated from seeds following a 12-hr soak in dilute alkaline solution using a series of grinding, screening, centrifugation, and washing steps. Isolated starches viewed by scanning electron microscopy yielded angular, polygonal granules 2 m in diameter. Starches displayed typical A-type crystalline packing arrangements as determined by X-ray powder …


Quality Attributes Of Dried Milk Products Packaged For Long-Term Storage, Michelle A. Lloyd, J. Zou, H. Farnsworth, Oscar A. Pike Jun 2002

Quality Attributes Of Dried Milk Products Packaged For Long-Term Storage, Michelle A. Lloyd, J. Zou, H. Farnsworth, Oscar A. Pike

Faculty Publications

There is a market for dehydrated foods, such as nonfat dry milk (NFDM), that are packaged for long-term storage in case of natural disasters or other emergencies. To maintain quality and optimize shelf-life, NFDM must be properly processed from good quality milk, well-packaged (minimizing moisture, light and oxygen), and stored appropriately. Research is needed to determine the variation in quality that exists in dried milk products intended for retail sale. The objective of this research was to evaluate and compare the quality of several types of dried milk products packaged for long-term storage. Ten brands of dried milk products (5 …


Creation Of Three Nutritional Mixes Based On Amaranth (Amaranthus Caudatus) And Other Andean Crops For School-Aged Children (Cochabamba-Bolivia), Sandra Carola Delgadillo Barriga Jan 2002

Creation Of Three Nutritional Mixes Based On Amaranth (Amaranthus Caudatus) And Other Andean Crops For School-Aged Children (Cochabamba-Bolivia), Sandra Carola Delgadillo Barriga

Theses and Dissertations

In Bolivia we have three very valuable Andean grains: amaranth (Amaranthus caudatus), quinoa (Chenopodium quinua), and canihua (Chenopodium pallidicaule), which combined with cereals and legumes can become a complete and balanced food in order to combat the malnutrition that is so widespread in our region. In this study, various nutritional mixes were formulated, based on amaranth and other Andean crops, and the three best were chosen according to nutrition, palatability, and cost. They were: Andean Baby Food, Mixicereal, and Amaranth Cookie, which have an amino acid complement between 79% and 100% and give satisfactory amounts of protein, energy, and minerals …
