Which is the Best Glucose Powder?

Glucose powder or dextrose powder is one of the most recommended energy restorer in case of dehydration, during and after workouts. Flavoured glucose powder is also catching the fancy of children and mothers also encourage as a source of rehydration after long playing hours. So, it becomes important to know what you are actually having in the form of glucose. We compared few popular brands like Glucon D and the latest on the block Patanjali to know which is the best glucose powder. Also read on to know which brands are safe for consumption and if they contain the recommended energy and mineral levels.

Overview

Glucose is a white crystalline powder which is readily absorbed in the bloodstream and hence it is a good source of energy. It helps to replenish the energy stores, especially during and just after workout. There are several brands of glucose powder in the market and one may note that most of these are proprietary food – this means there are no specifications for these in the food regulations. It’s important to know that a major ingredient in glucose powder is dextrose monohydrate. We tested eight brands of glucose powder including Patanjali’s Glucoshakti, which claims to be herbal. Interestingly, all of these brands, save Patanjali, claim to have 99.4 percent of glucose. Read on to find out if the test results bore out their claims.

Glucon-D

Key Findings

  • Based on the overall test findings, the top performer is Glucon-D. It is also the value-for-money brand.
  • Highest energy value was found in Dabur.
  • In the sensory panel tests, Multani scored highest and was followed by Glucon-D.
  • Dextrose content in ADPL fell short of their claim – it was found to be 98.8 gm/100 gm, as against their declared value (99.4). Dextrose in Glucoshakti was 98.40% but added herbal ingredients aloe vera 0.20 gm, ashwagandha 0.05 gm and satawari 0.05 gm and claims to be ayurvedic proprietary medicine.
  • Except Glucon-D and Patanjali, all other brands were found to have less vitamin D than their declared values. Vitamin D was quite low (below the detection limit of 2.0 µg/100 gm) in ADPL and Nice.
  • Calcium content in ADPL and Multani was found to be 121.7 mg/kg and 158.33 mg/kg, against their declared value of 170 mg/kg.
  • Phosphorus content in ADPL was a mere 10 mg/100 gm). Its declared value was 100 mg/100 gm.

TEST RESULTS FOR PHYSICOCHEMICAL PARAMETERS

 

Dextrose Equivalent

Dextrose monohydrate is the main ingredient in glucose powder. All tested brands claim to have 99.4 per cent of glucose. Since glucose is a good source of energy, higher is better.

  • Glucose was highest in Apollo (99.97 per cent).
  • Dextrose was lowest in Patanjali (98.4 per cent) and ADPL (98.8 per cent). Patanjali has not declared dextrose value on their label. Patanjali claims to be an Ayurvedic medicine and contains aloe vera (0.20 gm), ashwagandha (0.05 gm) and satawari (0.05 gm).
  • Dextrose content in ADPL was less than its declared value (99.4 per cent).

Energy Value

Glucose powder is a ready source of energy. In our tests, we compared the total energy value (per 100 gm of sample calculated in Kcal) with the declared value. Higher energy value is considered to be good for consumers.

  • Highest energy value was found in Dabur (369.56 kcal/100 gm), followed by Glucon-D (366.08 kcal/100 gm).
  • Energy value in all the brands was above the declared value.

Vitamin D

Vitamin D helps the body to use calcium from one’s diet and is therefore essential for strong bones. No recommended daily allowance (RDA) was fixed for vitamin D in Dietary Guidelines for Indians, 2011, of National Institute of Nutrition.

  • Vitamin D was found highest in Stenza (12.4 mcg/100 gm), though it was less than its claimed value (22.5 mcg/100 gm). The second highest amount of vitamin D was in Glucon-D (10.77 mcg/100 gm).
  • Except Glucon-D and Patanjali, all other brands were found having less quantity of vitamin D compared to their declared value.
  • Vitamin D was quite low (below detection limit of 2.0 µg/100 gm) in ADPL and Nice.

Calcium

Calcium is a mineral important for strong bones and teeth. As per Dietary Guidelines for Indians, 2011, issued by National Institute of Nutrition, the requirement of calcium for a young man/woman is 600 mg per day. So, a higher amount of calcium in glucose powder is better.

  • Highest amount of calcium was found in Stenza (216.84 mg/kg), followed by Glucon-D (202.17 mg/kg).
  • Calcium content in ADPL and Multani was 121.7 mg/kg and 158.33 mg/kg – as against their declared value of 170 mg/kg.

Phosphorus

Phosphorus is considered to be an essential nutrient required for proper cell functioning, regulation of calcium, and strong bones and teeth. Deficiency in phosphorus can lead to lowered appetite, anaemia, muscle pain, improper bone formation (rickets), numbness and a weakened immune system.

  • Phosphorus was found highest in Stenza (190 mg/100 gm).
  • Phosphorus content in ADPL was less (10 mg/100 gm) than its declared value (100 mg/100 gm).

Heavy Metals

These should not be present in higher than the limits specified in the national standards. We tested the eight brands for presence of arsenic and lead. For arsenic, the specified limit for glucose powder (‘foods not specified’ category) is 1.1 ppm (parts per million). Lead in glucose powder (‘foods not specified’ category) shall not be more than 2.5 ppm.

  • Both arsenic and lead were not detected in any of the tested brands, the detection limit being 0.1 mg/kg).

Microbiological Activity

We tested the brands for total plate count. The colony count per gram of the product should be on lower side (no limits have been specified in FSS Regulations). Due to improper or poor hygienic conditions during the manufacturing process, microorganisms may occur in the finished product. These are responsible for many food-borne diseases.

  • Total plate count in all the brands was found to be less than 10 cfu/gm, which means they are safe for consumption.

PHYSICOCHEMICAL SCORES

FOR SENSORY ATTRIBUTES

 

Panel members judged the samples for these sensory attributes: free-flowing tendency, taste and odour, and absence of colouring and foreign matter. The product shall be white or light cream in colour. It shall be crystalline or granular and odourless powder, readily soluble in water with a characteristic sweet taste that is free from foreign flavour. The panelists rated the samples on a 100-point scale.

  • Multani was rated as the most acceptable brand, followed by Glucon-D.

Score Rating: >90: very good*****, 71–90: good****, 51–70: fair***, 31–50: poor**, up to 30: very poor*
