Furthermore, mean zinc content reduced from 3 mg/100 g inmon bean to 2.26 mg/100 g inmon bean without prior soaking, giving a zinc retention of 75.6 . 4 DISCUSSION. The two methods that can be used to calculate nutrient retention are
May 23, 2018· Alkazine Zinc baths are less efficient and slower, but they produce a better thickness distribution and ductility. Step 4 Zinc Electroplating. Once ready for plating, the metal can be introduced to two methods of plating: either rack plating or barrel plating.
The results indicated that zinc bioavailabilities from three types of egg with six kinds of egg processing were ranged from 3.60 to 19.01 percents. Zinc content was ranged from 1.15 to 3.12 mg/100 g in wet basis or 2.59 to 12.22 mg/100 g in dry basis. Frying egg decreased zinc bioavailability and zinc content significantly plt0.05.
