The Relative Ripening Rate of the Grain and Straw of Ten Varieties Of
The relative ripening rate of the grain and straw of ten varieties of oats by Frank C Petr A THESIS Submitted to the Graduate Faculty in partial fulfillment of the requirements for the degree of Master of Science in Agronomy Montana State University © Copyright by Frank C Petr (1952) Abstract: Ten varieties of oats were compared for rapidity of dessication of the straw following maturity of the grain at Bozeman in 1951. Moisture content of the grain and straw was determined at nine consecutive 3-day intervals commencing 30 days after the heading date of each variety. The oat varieties were assigned maturity ratings of early, midearly, midseason, midlate, and late on the basis of heading date. The moisture content of the straw decreased slowly at successive stages and remained relatively high for all varieties throughout the experiment. No significantr differences in straw moisture at the final harvest were evident between varieties. The moisture content of the grain receded rapidly in all the varieties during the first four 3-day intervals. During the 24 days between the first and final harvest of each variety the grain moisture decreased from an average of 43.2 percent to 17.0 percent. The developmental period of the kernel apparently was shorter in Maganski 044 than in the other varieties in the test as indicated by the tendency of the grain to start dessicating in a shorter time after heading. Differential shattering resulting from hail was observed. Mission and Aberystwyth S84 were most resistant. Mission apparently derived its shatter resistance from its Markton parent, which was. -
Why Serious Bakers Have Mother Issues Andrea Strong
Why Serious Bakers Have Mother Issues Andrea Strong A sourdough starter, also known as a "mother." [Photograph: Shutterstock] They came from all over Europe—a village in Poland, a farm in Tuscany, a town in Bordeaux. They were carried across the continent, and trekked from the Old Country to the New World. There were arrests and clashes with the police. But through a combination of luck and love, they arrived in New York City where they now work quietly, often in the small hours of the morning. Not many people have even seen them; just a modest, elite group of artisans truly know them intimately. The bakers know their mothers, and these are their stories. But, wait, perhaps I should clarify. These aren't their actual mothers, as in the women who gave birth to them, who raised them, who are now, undoubtedly, the subject of therapy for one 45- minute hour per week. No, no. These are their "mothers"—also known as madre, seed, chef, and levain. Natural yeasts starters destined for some of the world's best sourdough breads, typically born of a combination of apples, grapes, and honey, left to ferment on a warm windowsill and grow a frosting of wild yeast and Lactobacillus bacteria. Yup, those mothers. [Photograph: Vicky Wasik] Mind you, starters do share qualities often associated with matriarchs (...and pets)—they often inspire love-hate relationships marked by serious dependency. Unlike commercial yeast, which requires little more than sugar and warm water to activate, mothers are needy. They demand regular feedings of flour and water in order to produce the organic acids, alcohols, and carbon dioxide necessary to make bread do that cool thing it does: rise. -
Quality of Wheat Germ Oil Obtained by Cold Pressing and Supercritical Carbon Dioxide Extraction

(2013): Quality of wheat germ oil obtained by cold pressing and supercritical carbon dioxide extraction. Czech J. Food Sci., 31: 236–240. Laboratory-prepared wheat germ oil was obtained by cold pressing and supercritical CO2 extraction. The main ob- jective was to compare the quality of both oil samples obtained, with emphasis on their fatty acids compositions and tocopherol contents. The percentages of palmitic, oleic, linoleic, and linolenic acids determined in the cold-pressed oil were 15.89, 15.48, 54.88, and 7.34% of total fatty acids, respectively, and those in the oil extracted by supercritical CO2 were 16.50, 15.05, 54.79, and 7.29% of total fatty acids, respectively. The average proportions of saturated, mono- and polyunsaturated fatty acids calculated for wheat germ oil obtained by cold pressing accounted for 17.15, 17.63, and 62.22% of total fatty acids, respectively, and those calculated for wheat germ oil extracted by supercritical CO2 were very similar, accounting for 18.14, 17.58, and 62.08% of total fatty acids, respectively. -
Whole Wheat Flour Stability: an Insight
Acta Scientific Nutritional Health Volume 2 Issue 3 March 2018 Review Article Whole Wheat Flour Stability: An Insight Navneet Singh Deora* Ingredient Innovation and Research, Jubilant Food Works, India *Corresponding Author: Navneet Singh Deora, Ingredient Innovation and Research, Jubilant Food Works, India. Received: January 04, 2018; Published: February 03, 2018 Abstract In the current scenario, millers as well as food Industries face many challenges in relation to the whole-wheat flour due to its limited stability in comparisons to refined flour. Lipid degradation by the action of enzymatic as was well non-enzymatic pathways seems to be a one of the leading causes of whole wheat flour stability. Milling technique is also of paramount importance to produce whole Wheat flour. To address the stability issues, retentions of available antioxidant during milling and inactivation of enzymes can be explored along with wheat bran stabilization. The purpose of this review paper is to address these key issues in the milling, shelf- Keywordslife, key biomarkers: of whole wheat flour and finally discuss the strategies to overcome existing challenges.

Estimation of Semolina Partially Substitution by Wheat Germ Flour in Specific a KSA Local Lovely Product
Middle East Journal of Applied Volume : 05 | Issue : 03 | July-Sept. | 2015 Sciences Pages: 670-675 ISSN 2077-4613 Estimation of Semolina Partially Substitution by Wheat Germ Flour in Specific a KSA Local Lovely Product Garsa Ali Al Shehry Nutrition and Food Science, College of Designs and Home Economics- Taif Univ., Saudi Arabia ABSTRACT Plant materials with high protein and fat contents are of great importance in the food technology, wherein, the significances are determined not only by their nutritional value, but also by the involvement in the formation of the basic functional and technological characteristics. Such properties are consequently impact on the consumer palatability of the final products. Therefore, the wheat germ powder (0, 5, 10 or 15%) was partially substituted by the same amount of the main ingredient (semolina flour) in a KSA local product (busbousa) formula. Major chemical compositions, anti-nutritional components and water and fat absorbance capacity of the wheat germ were compared to that found in original tested semolina. Impact of the existence substitutes on such tests, in addition to sensory evaluation, in the final product was, also, extended studied. The resulted data showed that, due to the significantly higher amounts of protein, fat, fiber and ash and the significantly lower antinutritional components, the whole wheat germ was more nutritious than semolina. Such findings cleared the fact that the higher wheat germ percent addition, the higher nutrients and lower antinutrition components existence in the final product. On the other hand, the sensory evaluation of the tested products showed that most of the studied attributes were more preferable in case of the 10% whole wheat germ than all the other tested busbousa formulas.
