Abstract

Calcium absorption from fumarate salts (calcium fumarate and calcium malate fumarate), which have recently been considered for use as sources for food and beverage enrichment, was compared to that from calcium citrate malate, calcium citrate, and calcium carbonate. Salts were instrinsically labeled with 45Ca and orally administered to Sprague-Dawley rats. Fractional absorption of calcium from each salt was determined using the femur uptake model. Fractional absorption from the five salts (0.30-0.27) was not significantly different (p > 0.05). Thus, when measured in the rat model, calcium from calcium fumarate and calcium malate fumarate is absorbed equally well as compared to other salts, which are common calcium sources in many foods, beverages, and supplements.

摘要

将最近被考虑用作食品和饮料强化剂来源的富马酸盐（富马酸钙和苹果酸富马酸钙）的钙吸收情况，与苹果酸柠檬酸钙、柠檬酸钙和碳酸钙的钙吸收情况进行了比较。这些盐用45Ca进行了内标，并口服给予斯普拉格-道利大鼠。使用股骨摄取模型测定每种盐的钙吸收分数。五种盐的吸收分数（0.30 - 0.27）没有显著差异（p > 0.05）。因此，在大鼠模型中测量时，与许多食品、饮料和补充剂中常见的其他钙源盐相比，富马酸钙和苹果酸富马酸钙中的钙吸收情况同样良好。
