Chemistry Life Hacks: Food Edition
TLDRThis chemistry-inspired video offers three life hacks to enhance your culinary experience. First, it shares a method to reduce the calorie content of rice by 50%, achieved by cooking it with coconut oil and refrigerating it for 12 hours, which transforms digestible starches into indigestible ones. Second, to prevent browning and maintain freshness of sliced fruits like apples and avocados, the video suggests soaking them in lemon water, utilizing the preservative properties of vitamin C and citric acid. Lastly, for tenderizing meat, a baking soda treatment is recommended, which raises the pH and water-holding capacity of the meat, resulting in a more tender and juicy chicken salad. These hacks are presented with scientific explanations to back up their effectiveness.
Takeaways
- 🍚 Adding coconut oil to boiling water before cooking rice and then refrigerating it for 12 hours can reduce its calorie content by up to 50 percent by creating an indigestible amylose lipid complex.
- 🍏 To prevent apple slices from browning, soak them in lemon water, which contains vitamin C and citric acid that act as preservatives and slow down the oxidation process.
- 🥑 The same lemon water technique can be used to keep other chopped fruits like avocados and pears fresh for longer.
- 🍗 To make chicken and other meats tender, marinate raw chicken cubes with baking soda for 15 minutes before rinsing and cooking. The baking soda increases the meat's pH, improving its water-holding capacity and resulting in a more tender texture.
- 🧂 Baking soda has a pH of around 9 and can be used to combat the toughening effects of lactic acid build-up in meat post-mortem by raising the pH and maintaining moisture.
- 🔁 The process of refrigerating rice with coconut oil and then rinsing it helps to convert digestible starches into indigestible ones, thus reducing the number of calories absorbed by the body.
- 🍋 Lemon juice can be used as a direct spray on apples or other fruits to prevent browning and maintain freshness without the need for a bowl of lemon water.
- 🥩 The texture of meat is influenced by its proteins and fats, with proteins providing structure and fats helping to retain moisture.
- 🕒 Allowing meat to sit in a baking soda solution for 15 minutes before cooking enhances its tenderness by increasing the pH and water retention.
- 🌡️ The pH of meat drops after an animal's death due to lactic acid build-up, which can lead to toughness and dryness if not managed properly.
- ✍️ Sharing additional food hacks in the comments may lead to their inclusion in future episodes, encouraging a community of culinary knowledge exchange.
Q & A
What is the main purpose of adding coconut oil when cooking rice in the described hack?
-The coconut oil reacts with amylose, one of the main components of starch in rice, to form an 'amylose lipid complex' when the rice is cooled. This complex is harder for the body to break down, which can reduce the digestible starch content and thus potentially cut the calorie content by up to 50 percent.
How does storing cooked rice in the fridge for 12 hours help in reducing its calorie content?
-Storing cooked rice in the fridge allows the amylose to form a complex with the coconut oil, which makes part of the rice indigestible and reduces the overall calorie content.
What is the enzyme responsible for browning in chopped fruits like apples and avocados?
-The enzyme responsible for browning in chopped fruits is polyphenol oxidase.
How does lemon water help in preserving the freshness of apple slices?
-Lemon water, rich in vitamin C (ascorbic acid) and citric acid, acts as a food preservative that slows down the enzymatic browning reaction caused by polyphenol oxidase, thus keeping the apple slices fresh for longer.
What is the role of baking soda in making chicken and other meats tender?
-Baking soda, with a pH of around 9, increases the pH of the meat, which enhances its water-holding capacity. This results in the meat retaining more moisture and becoming more tender when cooked.
Why does meat become tough and dry if its pH gets too low after the animal's death?
-When the pH of meat drops too low due to the buildup of lactic acid post-mortem, it can lead to a tough and dry texture because the proteins denature and lose their ability to hold water effectively.
What is the primary reason for the increase in water-holding capacity of meat when treated with baking soda?
-The increase in pH from the baking soda treatment allows the meat to hold more water, which contributes to a more tender and juicy result when cooked.
How does the process of making rice with coconut oil and storing it in the fridge affect its starch content?
-The process converts some of the digestible starches into indigestible forms by creating an amylose lipid complex, which reduces the amount of starch that the body can metabolize into glucose and potentially store as fat.
Why does the lemon juice or lemon water treatment help in maintaining the color and freshness of avocados and other fruits?
-The vitamin C and citric acid in lemon juice act as a preservative, slowing down the oxidation process catalyzed by polyphenol oxidase, which is responsible for the browning and off-flavor development in damaged fruit cells.
What is the recommended amount of baking soda to use per 12 oz of raw meat for the tenderizing hack?
-For every 12 oz of raw meat, it is recommended to add one teaspoon of baking soda.
How long should the meat be left to sit after adding baking soda before rinsing and cooking it?
-The meat should be left to sit for 15 minutes after adding baking soda before rinsing it off.
What is the final step recommended for viewers who have additional life hacks to share?
-The viewers are encouraged to post their additional life hacks in the comments section of the video, with the possibility of them being featured in upcoming episodes.
Outlines
🍚 Calorie-Reducing Rice Hack
The video introduces a method to reduce the calorie content of rice by half. This is achieved by first boiling water, adding two teaspoons of coconut oil, simmering the rice, and then refrigerating it for 12 hours. The cooling process forms an 'amylose lipid complex' with the oil, which is harder for the body to break down, thus converting digestible starches into indigestible ones, reducing the overall calorie intake.
🍏 Keeping Apple Slices Fresh
To prevent apple slices from turning brown and mushy, the video suggests soaking them in a bowl of water mixed with lemon juice. The vitamin C (ascorbic acid) and citric acid in lemon act as a preservative, slowing down the oxidation process catalyzed by the enzyme polyphenol oxidase, which is released when fruit cells are damaged. This method also applies to avocados, pears, and other fruits.
🍗 Tenderizing Chicken with Baking Soda
The video provides a tip for making chicken and other meats tender without marinating. By adding one teaspoon of baking soda for every 12 oz of raw meat, the meat is left to sit for 15 minutes before rinsing off the baking soda. Baking soda, with a pH of around 9, raises the pH of the meat, increasing its water-holding capacity and resulting in a more tender texture after cooking.
