Misunderstandings in Nutritious Meals A scientific view of the relationship between raisins and sugar

[ Hot Focus on Chemical Machinery and Equipment Network ] While economic development has made people's lives more prosperous and beautiful, it has also stimulated residents to pay more attention to their own dietary health
.
Today, a more balanced diet has become an important part of many people's refined lives, and various dietary recommendations have become their focus
.

 

In fact, the emergence of recommended recipes for healthy eating has indeed provided some help to the healthy life of many residents, but at the same time, the details in many recipes have become the entry point of rumors, such as the "raisin" we are going to say today.
"
.

 

Raisins are a regular in many recipes as a high-energy snack, often along with nuts, to supplement nutrients that are not readily available in regular diets, such as polyphenols
.
However, many people are skeptical about the nutritional value of raisins, and many self-media equates raisins with sugar, saying that the drying process destroys the nutrients in raisins and concentrates the sugar in them
.
In fact, this claim is a rumor
.

 

　　Generally speaking, raisins in nutritional recipes refer to raisins in a narrow sense, that is, dried fruit products formed by sun drying or artificial heating of grape fruits.
One of the characteristics of this food is that no other flavoring products are added, only by removing The moisture in the fruit meets the needs of transportation and storage
.
Although, from the perspective of nutrient loss, the transformation process does destroy the vitamins in grapes, but for other nutrients in grapes, such as potassium, magnesium, iron and other minerals, polyphenols, oligosaccharides, pectin, dietary Fiber has little effect
.
In addition, raisins are more natural than refined vitamins and health supplements because there is no need to add extra sugar and fat
.

 

　　In addition, in terms of purpose, the positioning of raisins in nutritional recipes is not to replace the staple food, but to be used as a complementary food, which is more like the existence of a snack after a meal
.
Compared with traditional snacks, it has less impact on blood sugar, but provides higher nutritional value
.
In addition, most of the current recipes will clearly label the intake of different ingredients.
From this point of view, the daily intake of sugar through raisins is not terrible, and these sugars are still fructooligosaccharides, so There is also no case where raisins can adversely affect weight or health
.

 

　　However, we need to pay attention to the fact that there is a flavored raisin among the raisins currently on the market
.
Although the main raw material of this raisin is dried grape pulp, flavoring agents such as white sugar are added, and food additives are appropriately used to improve the taste or prolong the shelf life
.
Compared with raisins in the traditional narrow sense, the nutritional value of this raisin has been reduced and it is not so healthy
.

 

　　At the same time, we also need to pay attention to the food safety of raisins themselves
.
Raisins may have quality problems due to raw material reasons or processing environment and transportation sanitation problems, such as microbial contamination, deterioration,
etc.
In the relevant testing indicators, there are also perfect specifications for these problems.
For example, the items involved in the microbial testing include the determination of the total number of colonies, coliform bacteria, mold testing, salmonella testing, Shigella, Staphylococcus aureus , Hemolytic streptococcus detection,
etc.
These tests often need to be completed in the testing center or laboratory with targeted analytical instruments
.
However, from the perspective of consumers, it is an effective way to avoid food safety problems in the purchase of raisins as much as possible by carefully reviewing the product ingredient list and identifying formal purchase channels
