    Notizen: A rotating chamber dry roaster using pre-heated ceramic beads as heat transfer media was used to roast navy beans. Processing conditions were: beads temperature, 240 and 270°C; bean-to-bead ratio, 1/10 and 1/15 and contact times of 1 and 2 min. Product temperatures achieved ranged from 92–125°C for the eight runs. Heat transfer coefficients varied from 3.6–23.4 W/(m2) (°C). Roasted products showed reduced water-soluble nitrogen content and gel forming capacity, increased water-holding capacity and cold paste viscosities, and no changes in available lysine and degree of starch damage. Residual trypsin inhibitor (TIA) and hemagglutinin activity varied from 92 to 22%, and 48 to 1%, respectively. A correlation was found to exist between nitrogen solubility index and TIA of products. Roasting caused fracture and separation of hulls, and facilitated their removal.

    Notizen: White cakes were prepared with substitutions of bran and middlings for both 60 and 70% extraction flours. Substitution levels included 4, 8 and 16% bran, 12% middlings bleached or unbleached, and 16% bran plus 12% middlings bleached or unbleached. Results of this study indicate that bran and middlings may be successfully substituted in the cake system. Batter viscosity increased with increasing substitution levels while the cake volumes were decreased only in cakes containing unbleached middlings. Substitutions of bran and/or middlings in the cake formula resulted in increased tenderness, yellowness and redness but lightness of the cake crumb decreased. The characteristics of specific gravity, shrinkage, symmetry, uniformity, pH and moisture, as well as sensory scores, were not adversely affected by bran or middlings substitutions.

    Notizen: Four foodservice production methods for growing alfalfa sprouts were compared. Growing sprouts using the Glass Container Method resulted in the largest numerical yield of sprouts (242g of sprouts/50g of seed), the smallest growth of bacteria (3.4 × 108 colony forming units/g) and the smallest total direct labor time (30 ± 2 min). Sensory evaluation of 1 and 14-day old sprouts indicated that although panelists could differentiate between treatments (p 〈 0.99) in a triangle test, no statistically significant preference for 1 or 14- day old sprouts could be detected. Service of sprouts at ≤3 days post-harvest is recommended to provide a product of highest possible nutritional value (≥12.02 mg ascorbic acid/100g alfalfa sprouts).

    Notizen: Pilot plant air classification or raw beans (Phaseolus vulgaris) produced high-protein fractions (HPF) containing 51.4% protein and high-starch fractions (HSF) having about 50% starch. Particle size distribution analyses and scanning electron micrographs confinned the fractionation of starchy and proteinaceous materials. Extruded corn/HSF blends had lower water absorption and water solubility indices, higher protein content, and a better balanced amino acid pattern than pure corn extrudates. Extrusion-texturized vegetable proteins obtained by substituting HPF for defatted soy flour at levels of 10, 20 and 30% had similar functional properties as the 100% texturized soy. Air classification followed by extrusion-cooking is a feasible alternative for dry-processing of beans into products for human consumption.

    Notizen: Eight Navy bean samples, roasted between 92 and 125°C in a particle-to-particle heat exchanger, were ground to produce whole bean and hull flours. Dehulled bean flours were also separated into high protein (HPF) and high-starch fractions (HSF) by air classification. Whole bean flours contained 1.92% fat and 25.8% protein on the average. Hull flours contained between 31.2 and 50.2% dietary fiber, of which approximately 60% was crude fiber. Dehulled bean flour containing 26.8% protein was fractionated into HSF and HPF with average protein contents of 15.6 and 43.1%, respectively. Greater protein shift may be further accomplished by finer grinding and adjustment of the cut point. Residual trypsin inhibitor activity of HPF s ranged from 25–108 TIA/mg protein, down from 116 units in the raw control HPF. Hemagglutinins were inactivated from 110 HA units/mg to values ranging from 2.4–105 HA units/mg.

    Notizen: Tallow or fractionated tallow could be utilized as suitable replacements for expensive imported fats. Detergent (aqueous) fractionation is applicable to beef tallow and involves the addition of water containing an inorganic salt (Na2SO4) and a surface active agent, sodium dodecyl sulfate (SDS), to a partly crystallized oil. Centrifugation yields olein and stearin layers. Investigation of four principal process variables revealed that olein production was maximized with (1) 5 hr of crystallization, (2) minimum stirring during crystallization, (3) subsequent addition of SDS to fractions, and (4) a 4:1 electrolyte to detergent ratio. A comparison with olein yields for current fractionation methods for tallow revealed that the modified procedure was rrore efficient.

    Notizen: Hull flours and air-classified intermediate starch, high starch, and high protein navy, pinto, and black bean flours were analyzed for mineral content and phytic acid. Phytic acid content ranged from 4.29-8.72 mg/g in the high starch flours to 23.74-30.22 mg/g in the protein flours. Total phosphorus content proved to be a good indicator of phytic acid content. Zinc, iron, potassium, and magnesium partitioned into the protein flours of each bean type. Strong and significant correlation coefficients obtained between phytic acid content and the content of these minerals, and between the content of these minerals and protein content suggest that metallic phytate complexes were present.

    Notizen: Synthetic polydimethylsiloxane (PDMS) fluids were evaluated for their potential use as noncaloric deep fat frying media, even though use of PDMS fluids as a food ingredient has not received FDA approval. Fish patties, French fries and cake doughnut holes were each fried separately in 35, 100, 350, and 1000 centistoke (est) PDMS fluids and in corn oil (control). Time/temperature relationships and product quality attributes were objectively measured. Of the PDMS fluids examined, the 35 est functioned most effectively as a synthetic frying medium due to efficient heat transfer and acceptable quality of foods fried in it. Fat content of each PSMS-fried food was one-quarter or less of the fat content of the corn oil-fried controls.

    Notizen: Navy beans (Phaseolus vulgaris) were dry roasted in a particle-to-particle heat exchanger, dehulled by air aspiration, pin-milled and air-classified to yield whole, hull, high protein, and high starch flour fractions. Proximate analysis, color, ENDF, starch, nitrogen solubility indices, and oligosaccharide contents of these flour fractions were determined. Compositional differences were demonstrated among all flour fractions. Stachyose was the major oligosaccharide in all fractions and was highest in the protein fraction. Substituting 10% bean flours for wheat changed water absorption and dough stability for all fractions. Dry roasted navy bean flour fractions appeared to be suitable ingredients for use in appropriate food systems.
