Instant Gajar Halwa Premix: My Journey at Vigyan Ashram

Introduction

Hi everyone! I’m excited to share my journey of working on an Instant Gajar Halwa Premix at Vigyan Ashram, Pabal. Under the guidance of Dixit Sir and for Tushar Kukreja Sir, I have been developing a convenient and tasty way to enjoy Gajar Halwa without the long preparation time. This project has been a fantastic learning experience, and I’d love to tell you all about it!

What is Instant Gajar Halwa Premix?

The Instant Gajar Halwa Premix is a ready-to-use mix that makes it super easy to prepare delicious Gajar Halwa in minutes. Just add milk or water, heat it up, and enjoy! The goal is to make this beloved dessert more accessible while keeping its authentic taste intact.

Why it is Important?

1. Convenience: No more long hours of grating carrots and slow cooking.
2. Long Shelf Life: It stays fresh for a long time without preservatives.
3. Nutritional Value: Maintains the goodness of carrots, milk solids, and dry fruits.
4. Market Demand: Instant and ready-to-eat foods are becoming increasingly popular, making this a promising idea.

Process & Challenges

Creating this premix wasn’t as easy as I first thought! Here’s what went into it:

• Ingredient Selection: Finding the best quality carrots, milk solids, sugar, and ghee.
• Drying & Processing: Testing different methods to dry the carrots while keeping their colour and nutrients.
• Taste & Texture Optimization: Balancing the flavours to get that rich, authentic taste.
• Shelf-Life Testing: Making sure the product stays fresh for a long time.

One of the biggest challenges was moisture control, as carrots have a lot of water content. I had to experiment with different drying techniques to keep the natural colour and flavour of the halwa intact.

Learnings & Experience

This project has taught me so much! I’ve gained hands-on experience in:

• Food processing and preservation methods.
• Nutritional analysis and ingredient selection.
• Problem-solving when dealing with real-world food production challenges.
• The importance of mentorship – a huge thanks to Dixit Sir and Tushar Kukreja Sir for their guidance!

Future Scope

I believe this premix has great potential beyond just personal use. It could be sold in:

• Ready-to-eat food segments.
• Grocery stores and online marketplaces.
• Export markets for Indian sweets.

There’s still room for improvement – I’d love to explore different flavours, a sugar-free version, and better packaging for extended shelf life.

Conclusion

Working on this project has been an exciting journey full of learning and innovation. It feels amazing to combine tradition with convenience, making Gajar Halwa more accessible in today’s fast-paced world. I’m looking forward to refining this product further and seeing where it goes!

These are the things that I focus on the most during practice .

21/03/2025

I prepare the 2nd SET –

For 2nd trial Here i use carrots

Processing the Carrots

1. Raw Material Preparation
   • We started with 2000g of carrots.
   • After peeling and cleaning, 269g of waste (about 13.45% of total weight) was recorded.
   • This waste percentage helps in evaluating peeling efficiency and material utilization.
2. Boiling Process
   • A container was heated to 100°C, reaching the boiling point of water.
   • The cleaned and chopped carrots were added and boiled for 13 minutes to achieve the desired softness.
3. Following the Standard Process
   • After boiling, we proceeded with the same steps as our previous trials, ensuring consistency in drying, grinding, and mixing with other ingredients for the premix.

Key Observations & Improvements

• Yield & Consistency: The final yield of the premix needs to be compared with previous batches to ensure uniform results.
• Texture & Colour: The boiling time and temperature affect the colour retention of carrots; maintaining a controlled process is crucial.u
• Waste Reduction: If waste percentage varies significantly across batches, adjustments in peeling and cutting methods can be explore

This is the SET NO. –02

SET NO. -03

In the first trial, I made a fully cooked version of Gajar Halwa and then tried to dehydrate it. However, the texture and taste were not as expected after rehydration.

In the second trial, I focused on making a simpler and better formulation by dehydrating the individual ingredients separately (like carrots, khoya, etc.) and then mixing them. This gave a better result in terms of flavour and appearance.

Therefore, I selected the second trial method as the base for my final premix formulation.
Now, in the third trial, I am focusing on standardizing the ratios, improving taste, and testing shelf life. I am learning from each trial to improve the final product step by step.

Here i make a trial for process control :

• Initial carrot wt. – 5kg
• Waste – 700g
• Final wt. – 4300g
• Wt. after cooking – 4200g
• Boiling Water – 5lit

Process as it is follows :-

First i Weight the Carrots (2000 gm)

↓

I Remove Waste The waste weight is (269 gm)

↓

Place a container on the gas to Boil Carrots

↓

Carrots were boil for 13 Minutes at 100°C

↓

After that Cool the Carrots at Room Temperature

↓

After that all the carrots were grated in grate machine

↓

Spread Grated Carrots on Tray

Calculations of the heat required:

Specific Heat:

Q=MCΔT

Q=Heat energy (in joule or calory)

M= Mass of water(in kg)

C= Specific heat capacity of water (4.186J / g °C )

ΔT= Temperature change (in °C)

Here,

volume of water = 5lit

Density of water = 1kg / l , so mass = 5kg – 5000g

Temperature change (ΔT) = heating from 25°C to 100°C

ΔT = 100-25=75°C

Specific heat of water (C) = 4.186J / g °C

Q = (5000) × (4.186J / g °C ) × (75°C)

Q = 1570000 J OR 1.57 MJ (Mega joule)

LPG = 1.57MJ / 30MJ/KG

=0.0523kg

= 52.3gm

here we use commercial thats why the consumption of the LPG is twice

LPG per kg = 63Rs

=104.6× 0.063

=6.6 RS

here i calculate the specific heat we required in process is ”1.57MJ”

26/03/2025

After discussion with Dixit sir the product were parcel to Tushar Kukreja sir for tasting or review

3 packets of each SET NO 01 or 02 are parcel to Kukreja Sir to taste.

28/03/2025

I done the proper pre mix packet recipe of SET NO.-02

First i take a packet with mixed all ingredients

↓

Heat a pan on a low flame and add 8 ml of ghee.

↓

Add the entire packet of Instant Gajar Halwa Premix to the pan and stir gently.

↓

Pour in 300 ml of milk and mix well.

↓

Increase to medium flame and continue stirring for approximately 8 minutes.

↓

Allow the milk to evaporate completely, transforming it into khoya.

↓

Stir thoroughly for an additional 2 minutes to achieve the perfect consistency.

As this information i want to go on further days.

06/04/2025

I had a Review with the Prasad sir, Dixit sir, Abhijeet sir from that review i have edit my blog from that review i have clear to work on the gajar halwa cooking process standards in the upcoming further trail and days i have work on it, and done the costing of the dehydrated onion costing for Rudra and Rutika.

07/04/2025

I tried SET NO.04:-

Today i done the 4th trail

The process i done by before trails as it is, for cooking of the carrots.

I take a readings in between cooking, 1- 14 min readings of the Temp.

and observe the cooking steps of the carrots

Observation:

The carrots are cooked well for 14 min at 102°C,

I use the visual, touch and use knife to check the carrots are cooked or not,

The knife were pressed and if it is goes to the middle of the carrots very easily,

This is my observations for the cooking process.

Time / Min	Temperature (°C)	Texture
1	60	No Change
2	70	No Change
3	80	No Change
4	90	No Change
5	93	No Change
6	95.7	No Change
7	96	Slightly soft from surface
8	97	Slightly soft from surface
9	97.5	Slightly soft from surface
10	98	Slightly soft from surface
11	98.3	Slightly soft from middle
12	99	Slightly soft from surface
13	99.3	All the parts are soft and well cooked
14	102	Cooked well

Problem:

I put all the carrots into the electric dryer for drying, but after 2 hours, the electricity went off due to some issue. As a result, the dried carrots got contaminated due to moisture content.

Due to the power outage, the carrots didn’t dry properly and got spoiled because of the moisture, so I gave them to the chickens to eat.

1. Empathize (Understand the Users)

Focus on who will use the premix and what their needs are.

• Target Users: Busy homemakers, working professionals, students, sweet shops, caterers, or anyone wanting traditional Gajar Halwa instantly.
• User Needs:
  • Quick and easy preparation
  • Authentic homemade taste
  • Long shelf life
  • No need to add many extra ingredients
  • Affordable and hygienic
• Pain Points:
  • Time-consuming to make halwa from scratch
  • Seasonal availability of carrots
  • Inconsistent taste
  • Storage issues for fresh halwa

2. Define (Problem Statement)

Craft a clear problem statement based on the user’s needs.

“People love the taste of traditional Gajar Halwa but find it time-consuming and difficult to prepare, especially when carrots are not in season. There is a need for a ready-to-cook premix that delivers the same authentic flavor, texture, and aroma with minimal effort and a long shelf life.”

3. Ideate (Explore Solutions)

Brainstorm ideas that solve the defined problem.

• Use dehydrated grated carrots with ghee and khoya powder
• Add natural preservatives for shelf life (e.g. citric acid, vacuum sealing)
• Make it ready by just adding milk or water
• Offer in different packaging sizes (single-serve, family pack)
• Include jaggery or sugar variants for different preferences
• Use vacuum packing or nitrogen flushing to increase shelf life
• Add instructions in regional languages for rural users

4. Prototype (Build a Sample)

Create small-batch samples to bring the idea to life.

• Trial with different proportions of grated carrot, ghee, milk solids, sugar
• Experiment with dehydration techniques (solar dryer, hot air oven, etc.)
• Try packaging options: vacuum sealing, zip-lock pouches, etc.
• Label with branding, ingredients, cooking instructions
• Shelf-life testing under different conditions

5. Test (Get Feedback)

Test your prototype with real users and improve it based on feedback.

• Share with local users (staff, students, villagers, customers at Vigyan Ashram)
• Collect feedback on:
  • Taste, texture, aroma
  • Ease of preparation
  • Packaging and instructions
  • Shelf life and storage convenience
• Modify recipe or process based on what works best

I am at the first step of the my ‘Product Development’ Journey, Now i have to work on standardise and pilot the design of the product.

09/04/2025

Troubleshooting Dryer Issues:

At Vigyan Ashram, ensuring all equipment works smoothly is crucial for maintaining the quality of our food processing work. Recently, I encountered an issue with the dryer that was affecting our production process.

Initially, I observed that the dryer was not functioning properly. To identify the problem, I carried out a basic test and routine maintenance. Despite these efforts, the issue remained unresolved.

Upon closer inspection, I discovered that the root of the problem was the start button of the dryer. It was not functioning properly, which prevented the machine from starting or operating effectively. This small but critical fault was enough to halt the entire drying process.

I discussed the issue with Jadhav Sir to seek a possible solution. However, even after troubleshooting together, the dryer was still not working well. We tried different approaches, but the problem persisted.

This experience highlighted the importance of regular checks on not just the internal systems but also on basic controls like switches and buttons.

We are now exploring further repair options or replacements for the faulty start button to ensure the dryer can resume full functionality as soon as possible.

And parallelly i have done and help to the Akshay Nikam for doing solar dome dryer trail on onion.

Tushar Kukreja Sir visited Vigyan Ashram to review and discuss the ongoing project details. His visit was an important opportunity for us to share our progress, challenges, and upcoming plans. We also discussed ways to improve efficiency and product quality in our current development projects. Overall, it was a learning experience that reinforced the value of teamwork, problem-solving, and expert guidance in practical work.

During this time, Tushar Kukreja Sir visited Vigyan Ashram to review and discuss our ongoing projects. His visit was a valuable opportunity to share our progress, discuss challenges, and gain feedback. The conversation helped us understand how to further improve our work and maintain quality in every step of the process.

Gajar Halwa Premix – New Trial Update

I also conducted another trial of the Instant Gajar Halwa Premix, repeating the method from my first trial with one key modification:
Sugar content was reduced from 40g to 30g.

This small change resulted in a well-balanced sweetness, and the overall taste and texture of the halwa turned out very nice. It’s exciting to see how small tweaks in formulation can improve the final product.

Comparison with Market Product

To evaluate our product better, I also tried the Ready-to-Eat Gajar Halwa from Dorabjee’s brand and compared it with our premix trial. This comparison helped me analyse differences in texture, flavour, sweetness, and aroma. While Dorabjee’s product is convenient and consistent, I found that our premix had a more traditional taste and fresher feel, especially with the reduced sugar.

I make this Dorabjee’s packet premix:-

Flow Chart:-

I Open the packet

↓

add 100ml boiled water into it

after that i place it for 5 min and close the tin on it

12/04/2025 – 13/04/2025

I tried SET NO.05:-

Initially, I explained the entire process of dehydrating carrots to Tushar Kukreja Sir, from start to finish, to help him understand the exact method I am following.

Ingredient: Carrots – 1400gm

Cooking Process (Latest Trial)

In previous trials, I used to peel the carrots before processing. However, in the current trial, I did not peel the carrots. Instead, after thoroughly washing them, I only removed the tail ends.

Drying:
The grated carrots were then placed in the dryer and dehydrated for 6 hours at 60°C

Boiling:
The unpeeled carrots were boiled for 14 minutes at 102°C.

Grating:
After boiling, the carrots were grated into two sizes:

Small size: 400 gm

Medium size: 850 gm

Waste (inedible or unusable parts): 150 gm

Drying:
The grated carrots were then placed in the dryer and dehydrated for 6 hours at 60°C

This is the big size grated carrots picture:

This is the small size grated carrots picture:

Tushar Sir and I conducted a trial on our premix using various ingredients, like using only sugar and including substituting sugar with jaggery.

With sugar:-

NOTE:

For this trial, I used previously dehydrated carrots in the recipe. This decision was made because the dehydration process takes approximately 6 hours, and Tushar Sir did not have enough time to wait for freshly dehydrated carrots during the trial. Hence, to proceed efficiently, I used carrots that were already dehydrated in an earlier batch.

INGREDIENTS:

• Dry carrot – 25gm
• Ghee – 5gm
• Dry Fruits – 5gm
• Cardamom Powder – 1gm
• Milk – 150ml
• Sugar – 30gm

Recipe as it is as first trial:

Here is the result of that:

With Jaggery:-

INGREDIENTS:

• Dry carrot – 25gm
• Ghee – 5gm
• Dry Fruits – 5gm
• Cardamom Powder – 1gm
• Milk – 150ml
• Jaggery – 30gm

Recipe as it is as first trial:

Here is the result of that:

Observation:

Review: between sugar, Jaggery.

sugar	Jaggery
Sugar halwa is good in taste Appearance was good Texture was good sweetness is balanced cooked properly rehydrate well Moisture content was balance it doesn’t loose water The customer doesn’t interesting into consume sugar.	Jaggery halwa also good in taste Appearance was good Texture was good sweetness is balanced cooked properly rehydrate well Moisture content was balance it doesn’t loose water The customer interesting into consume Organic jaggery.

The discussion start with Dixit sir, Ranjeet sir, Tushar kukreja sir on use the jaggery for substitute of sugar. Initially, the process involved drying and cooking the grated carrots directly in sweetened milk or plain milk. As a substitute for refined sugar, we experimented with natural sweeteners such as jaggery powder, raisins powder, dates powder, and other similar ingredients. After conducting multiple trials, we decided to modify the method.

14/04/2025

Abhijeet sir:

• They are satisfy with cooking

• Moisture content was balanced
• Aroma and taste is like extremely
• They say halwa smell like milk
• If the more sweeten the halwa the experience was more fantastic
• Overall acceptability is like extremely

Dixit sir and i have a discussion, As we discuss,

In the new trial, the process begins by grating the carrots and partially drying them to reduce their moisture content by approximately 50%. Once semi-dried, the carrots are cooked in ghee to enhance their flavour and richness. After this, milk is added and the mixture is allowed to soak and cook thoroughly. Finally, the product is further dried until only about 10% moisture remains, ensuring better shelf life and concentrated flavour.

15/04/2025

I had a discussion with Prasad Patil Sir about the review. He asked me to write my project summary.

I have written the entire project flow chart in the summary.
