FDA considers health claim for nuts
Nuts; nut cracking; and pitted stones at Gesher Benot Ya'aqov; Israel
The Acheulian site of Gesher Benot Ya'aqov (Israel) has revealed a unique association of edible nuts with pitted hammers and anvils. Located in the Dead Sea rift; on the boundary between the Arabian and African plates; the site dates to the Early-Middle Pleistocene; oxygen isotope stage 19. In a series of strata; seven species of […]
Antioxidant properties of plum concentrates and powder in precooked roast beef to reduce lipid oxidation
Boneless beef roasts (Semimembranosus + Adductor) were injected (20%) with a brine containing (1) no plum ingredient (control); (2) 2.5 or 5% fresh plum juice concentrate (FP); (3) 2.5 or 5% dried plum juice concentrate (DP); or (4) 2.5 or 5% spray dried plum powder (PP). Whole roasts were cooked; vacuum-packaged and stored at
Priority Areas for Research on the Intake; Composition; and Health Effects of Tree Nuts and Peanuts
This article summarizes the main conclusions drawn from a conference on the health effects of nut consumption and identifies priority areas for future research. Individuals with higher intakes of nuts generally have higher intakes of many beneficial dietary constituents. More information is needed on nut composition; the bioavailability of nutrients; and other bioactive constituents. Better […]
Antioxidant activity; ascorbic acid and total phenol of exotic fruits occurring in Brazil
The antioxidant activity; ascorbic acid and phenolic content were studied in 10 exotic fruits from Brazil: abiu; acerola; wax jambu; cashew; mamey sapote; carambola or star fruit; Surinam cherry; longan; sapodilla and jaboticaba. The ascorbic acid was determined by 2;6-dichloroindophenol titrimetic methods and total phenols were measured colorimetrically using the Folin-Ciocalteu reagent. The antioxidant activity […]
Dose-dependent effects of walnuts on motor and cognitive function in aged rats
Aged rats show decrements in performance on motor and cognitive tasks that require the use of spatial learning and memory. Previously we have shown that these deficits can be reversed by the polyphenolics in fruits and vegetables. Walnuts; which contain the n-3 fatty acids % walnut diet for 8 weeks before motor and cognitive testing. […]
Biochemical Characterization of Soluble Proteins in Pecan [Carya illinoinensis (Wangenh.) K. Koch]
Pecans (cv. Desirable) contained approximately 10% protein on a dry weight basis. The minimum nitrogen solubility (5.9-7.5%) at 0.25-0.75 M trichloroacetic acid represented the nonprotein nitrogen. Among the solvents assessed for protein solubilization; 0.1 M NaOH was the most effective; while borate saline buffer (pH 8.45) was judged to be optimal for protein solubilization. The […]
Formation of Lipid Oxidation and Isomerization Products during Processing of Nuts and Sesame Seeds
The aim of the present study was to quantify some nutritional and safety quality parameter changes that take place in nuts (roasting) and sesame seeds (dehulling; roasting; milling; and sterilization) during processing. Such evaluation was based on chemical analysis of various indicators of lipid alteration in raw and processed pistachios; almonds; peanuts; and tahina. Lipid […]
Antioxidant properties of dried plum ingredients in raw and precooked pork sausage
Raw pork sausages with no antioxidant (control); 3% or 6% dried plum puree (DP); 3% or 6% dried plum and apple puree (DPA); or 0.02% butylated hydroxytoluene and butylated hydroxyanisole (BHA/BHT) were (1) stored raw in chubs at 4 degrees C (RR) and evaluated weekly over 28 d; (2) cooked as patties; vacuum packaged; and […]
Tree Nuts and Peanuts as Components of a Healthy Diet
Nuts have been part of the diet for thousands of years. In 2003; a Qualified Health Claim was approved; stating that eating 1.5 oz (42 g) of nuts per day may reduce the risk of heart disease. Usual intakes fall short of this recommendation. About one-third of Americans report consuming nuts (tree nuts or peanuts) […]
