Infant food, milk preparation

Whole cow s milk is recommended for infant feeding when the infant over six months of age is eating approximately 20 g beikost (foods other than milk or formula) daily (i.e., equivalent to about one and one half 4.75 oz jars (135 g) of strained foods commercially prepared for infants) (Anderson et al. 1985 American Academy of Pediatrics 1983,...

Products prepared from soy protein products and resembling chicken, ham, frankfurters, and bacon are available commercially. Soy protein isolates are used in place of milk proteins or sodium caseinate in products such as coffee creamers, whipped toppings, yogurt, and infant formulas (see Dairy substitutes). Soy protein products also are used in snacks and in baked foods. 

Among the vitamin K vitamers, only phylloquinone is accounted for routine food analysis. Furthermore infant formulas, both milk-based and soy protein-based, are supplemented with a synthetic preparation of phylloquinone (the only form admitted) [403], which usually contain about 10% of the biologically inactive ctT-isomer [497]. 

Currently, high-performance liquid chromatography (HPLC) methods have been widely used in the analysis of tocopherols and tocotrienols in food and nutrition areas. Each form of tocopherol and tocotrienol can be separated and quantified individually using HPLC with either a UV or fluorescence detector. The interferences are largely reduced after separation by HPLC. Therefore, the sensitivity and specificity of HPLC methods are much higher than those obtained with the colorimetric, polarimetric, and GC methods. Also, sample preparation in the HPLC methods is simpler and more efficiently duplicated than in the older methods. Many HPLC methods for the quantification of tocopherols and tocotrienols in various foods and biological samples have been reported. Method number 992.03 of the AOAC International Official Methods of Analysis provides an HPLC method to determine vitamin E in milk-based infant formula. It could probably be said that HPLC methods have become dominant in the analysis of tocopherols and tocotrienols. Therefore, the analytical protocols for tocopherols and tocotrienols in this unit are focused on HPLC methods. Normal and reversed-phase HPLC methods are discussed in the separation and quantification of tocopherols and tocotrienols (see Basic Protocol). Sample... 

Foods are supplemented with vitamin A in the form of standardized preparations of synthetic fatty acyl esters, nowadays chiefly retinyl palmitate. The preparations are available commercially as either dilutions in high-quality vegetable oils containing added vitamin E as an antioxidant or as dry, stabilized beadlets in which the vitamin A is dispersed in a solid matrix of gelatin and sucrose or gum acacia and sucrose. The oily preparations are used to supplement fat-based foods such as margarines the dry preparations are used in dried food products such as milk powder, infant formulas, and dietetic foods (24). 

To date, the APT with foods is not well standardized and different methods in preparing the test materials are likely to cause controversial results. Most studies with foods have been performed with cow s milk, hen s egg, and wheat. The fresh foods should be preferred over commercial extracts for testing. The APT with foods like cow s milk or hen s egg has been studied in infants and children since food allergy plays a role especially in this age group, whereas aeroallergens (house dust mite) have been studied more intensively in adults (Turnjamaa et al., 2006). 

Potassium iodide is prepared in tablets, making it easier to store. Infants and children, though, cannot swallow tablets. When dissolved in water, the fluid is too salty to drink (Food and Drug Administration, 2002). To disguise the salty taste of the potassium iodide, the tablet can be crushed and mixed with raspberry syrup, low-fat chocolate milk, orange juice, or flat soda (cola) (Pelsor, Sadrieh, Machado, 2002). Nurses or parents can crush one 130-mg potassium iodide tablet into small pieces add 4 teaspoons of water to the crushed tablet to dissolve it then add 4 teaspoons of one of the aforementioned fluids to the mixture (U.S. Food and Drug Administration, 2002). Each teaspoon contains 16.25 mg of potassium iodide. This mixture will keep up to... 

Different parts of M oleifera, i.e., leaves, flowers, roots and fraits, have traditionally been used for dietary purposes (110). In India and Philippine, village people use the fresh leaves to prepare fat foods (38,110). Fresh leaves have been used by Indian inhabitants for the preparation of cow and buffalo ghee from butterfat (107). The leaves mixed with chicken soup are used by Philippine women to enhance breast milk production (4). The leaves are also eaten commonly as a food by infants and children in Sonth India (28). The tree leaves are eaten as greens in salads and in vegetable curries in Malaysia and the Indian sub-continent (15,39). In Nigeria, M. oleifera leaves are eaten as cooked vegetables (28). 

USE Both forms of lactose are employed, with the a-form predominating as a nutrient in preparing modified milk and food for infants and convalescents (Whittier, "Lactose and Its Utilization. foe. cit review with 327 ref). In baking mixtures. Pharmaceutic aid (tablet and capsule diluent). To produce lactic acid fermentation in ensilage and food products. As chromatographic adsorbent in analytical chemistry. In culture media. For many other uses see the comprehensive review by Weisberg Recent Progress in the Manufacture and Use of Lactose, toe. cit. 

The volume of food ingested by the infant is small, iodine content in formula preparations is insufficient, and parenteral nutrition does not supply enough iodine. This problem is not exclusive to Spanish premature babies, as the iodine content of many formulas in other countries is also inadequate. Therefore, supplements should be added if iodine intake is found to be inadequate. Breast milk appears to be the best source of iodine for the premature infant. 

Human exposures to lead in the diet historically comprised a major fraction of overall lead exposures in the United States and elsewhere, especially for adults. However, in a number of instances, such as infant consumption of Pb in evaporated milk from lead-seamed cans, many children also sustained significant dietary Pb exposures. Dietary lead intakes, for purposes of this chapter, are separated from drinking beverages prepared from drinking water, but include foods cooked in tap water containing Pb. 

Pantothenic acid itself is not used as it is hygroscopic and unstable. Its more stable sodium salt and, especially, the calcium salt are synthesized chemically and used pharmaceutically, mainly in solid multivitamin preparations and as an additive compound for some foods (such as infant milk formulas) and domestic animal feeds. Calcium pantothenate is most stable in almost neutral media (pH 6 to 7). Salts of pantothenic acid are colorless crystals and less hygroscopic (especially the calcium salt) than pantothenic acid. The solubility of calcium pantothenate in water at 25°C is 0.356 g/mL, whereas the sodium salt also is very water soluble. 

The issue of bioavailability from food sources and the interactions between food groups and copper availability remains a critical question. Lonnerdal et al. demonstrated that heat treatment of cows milk formula decreases the copper bioavailability. Transitional complexes form in the milk upon heating that have a similar configuration to copper and thereby directly inhibit copper absorption. High doses of zinc also reduce copper bioavailability, as does combined iron and zinc supplementation. The dilemma is how to prepare an infant formula containing adequate copper, iron, and zinc that will meet the RDA for copper. Other nutrients dramatically affect copper absorption from foods. Soy protein-based diets promote less copper retention in tissues than lactalbumin-based diets. However, it is unclear if this effect is solely due to the soy protein composition or to the higher zinc in these soy-based formulas. In animals, phytate causes a drop in serum copper but human stable isotope studies reveal no...
