In this study, carbonated fruit drink and cola beverage were prepared by sucrose and fructose syrup 55. The physicochemical properties of these samples were measured and compared. Three treatments for both types of drinks were considered: 100 % sucrose; 100 % fructose syrup 55; 50 % sucrose and 50 % fructose syrup 55. Changes in the sugar profile of both types of drinks and turbidity of carbonated fruit drinks were measured in a 45-day period by HPLC and turbidimeter, respectively. It was observed that during storage, some parts of sucrose in both drinks were hydrolyzed into glucose and fructose. The degree of hydrolysis in the case of cola was greater than that of carbonated fruit drink. According to the obtained results, the degree of sucrose hydrolysis was lower than 10 % for carbonated fruit drinks after 45 days of storage, while for cola drinks this value was about 30 %. The turbidity of carbonated fruit drinks prepared by fructose syrup was lower than those prepared by sucrose. The greater the substitution of sucrose with fructose syrup, the lower the turbidity.

Fructose syrup 55 is a low-cost alternative to sugar, which these days has experienced a high demand. A simple statistical chart shows that desire and the consumption of fructose syrup 55% has increased compared to sucrose in the last few years in the United States. The impact of sugar producers on the current US market is minimal due to the low cost of imported sucrose and corn syrup; as a consequence, the lower the price of corn syrup for food and drink which lead to the lower product price.

The honey bee obtains its all nutritional  demands from nectar and pollen. In the case of nectar and pollen limitation, beekeepers use a substitute. It has been a long time that sucrose is used as the conventional substitute for nectar and pollen in the bee feeding to provide its nutritional needs during winter and stimulation of springchr('39')s larval nourishment. High fructose corn syrup is another potential substitute that is used recently in bee feeding. Therefore, in this review, the effects of honey bee feeding with fructose syrup have been investigated. Life span and hive population are among the important factors that have to be considered in the case of feeding honey bee with various sources. According to the results of previous studies, high fructose corn syrup (containing 55 % fructose based on the dry matter) is a potential carbohydrate source for the honey bee compared to sucrose. In this review, the results of these studies have been investigated. The Scopus database was used for search purposes and three seraching algorythms (until 2020) was carried out as follows: (TITLE (honey AND bee) AND TITLE-ABS-KEY (hfcs)) and (TITLE (honey AND bee) AND TITLE (sucrose)) and (TITLE (honey AND bee) AND TITLE-ABS-KEY (fructose)).
