量热计用于滋补类食品热值测定分析

Determination and Analysis of Calorific Value of Nourishing Foods by Calorimeter

热值作为衡量物质品质的一个重要物理数据,从能量角度为评价同类食品品质提供一种新思路和方法。利用氧弹量热计测定12种常见滋补类食品的热值,12种滋补类食品的热值范围在13.09~32.46 k J/g之间。量热计测定热值试验方法简单、操作简便、数据可靠。了解滋补类食品的热值对人群的膳食结构及对此类食品的加工利用、贮藏、食用等方面都具有一定的指导和参考意义。

The calorific value as an important physical data to measure the quality of materials, the calorific value can provide a new idea and method for evaluating the quality of similar foods from the energy point of view. The calorific value of 12 kinds of nutritious foods was determined by oxygen bomb calorimeter. The results showed that the calorific value of 12 kinds of nourishing foods was between 13.09 k J/g and 32.46 k J/g. The determine method is simple, easy to operate and the results are reliable. Understanding the calorific value of nourishing foods has certain guiding and reference significance for the dietary structure of people and the processing and utilization, storage and edible of such foods.
