Method to analyze Ascorbic acid in Juices

In this video, we demonstrated a simple analytical method to determine the ascorbic acid content in fruit juices using a reflectometer, RQflex. Little sample preparation is required to set up this analysis. More information on this analytical method is available here: ms.spr.ly/6054bmax6 Other application notes: ms.spr.ly/6055bmaxB

Hi! I'm George from Kenya.
Can you please share the commercial procedure for making Fruit Juices.
Is there a book on the same and which documents the quality control procedures for Juices.
Thank you!

Hi George - Thanks so much for your feedback. As a supplier of rapid chemical tests for in-process control in food and beverage industries, we are not familiar with commercial procedures for making fruit juices. You may seek support from local sources such as government agencies related to agriculture and food processing. There may be industry associations related to food processing or beverage production that may offer support, training, or networking opportunities.
Quality control procedures are essential for ensuring the safety, consistency, and quality of fruit juices. The specific quality control measures may vary based on the scale of production, regulatory requirements, and the type of fruit juices being processed. We offer various rapid tests for in-process control including MQuant® Ascorbic Acid Test that is used to determine levels of natural ascorbic acid (vitamin C) in foods such as fruit and vegetable juices, and also to check how much ascorbic acid has been added to certain foods as a preservative or antioxidant.
Hope this helps!

Can I mix ascorbic acid to assorted drinks?

[@MerckLifeScience]

Thanks for your question!
It's important for beverage manufacturers to comply with the local food additive regulations to ensure their products are safe for consumption and meet quality standards. If you're a beverage manufacturer, or considering commercial production of drinks containing ascorbic acid, it is advisable to consult the specific regulations and guidelines applicable in your country or region. The Reflectoquant Ascorbic acid test strips presented in the video are suitable for quickly measuring levels of natural ascorbic acid in food and beverages.
