Hi everyone, it’s Leon the Milkman here and today we are talking about rennet and how it sets milk if you have possible issues with the rennet-setting of milk how to solve them so either you have a problem with the milk or the rennet or both. So what issues can we have with Rennet? Well, firstly you could be using too little. So we normally need about 30 to 40 IMCU’s per liter of milk, so if I want to rennet 100 liters of milk and I’ve got liquid rennet with a strength of 600 IMCU, 600 divided into the 3000 IMCU I need to set the 100 liters of milk would give me 5 so I would need 5 milliliters of that 600 IMCU strength rennet to set the 100 liters of milk for which I need a minimum of 3000 IMCU. Also, we could be using the rennet at too low a temperature remember rennet is a stomach enzyme originally and even the microbial rennets need close to body temperature to function optimally um we could be using too high temperatures or hot water to make up the rennets and that would knock off animal rennet 40 to 41 degrees Celsius is normally already too much for animal rennet the microbial rennets can take it a little bit more heat. It could also just be that the rennet is too old, so we can do a little bit of a rennet, test we can take some raw milk heat it up to 35 Celsius in the microwave add a few drops of the rennet, and see if the milk sets. If it works then your rennet is still active then on the milk side um could be that your milk is diluted so there’s water addition that would dilute the protein and the soluble calcium both play important roles in the setting of the milk could also be that the milk is over-pasteurised so um when the milk is used for long life milk or UHT, ultra-high temperature milk then the temperatures are too high there is too much denaturation of the protein and the casein, the structure actually changes so with the rennet being an enzyme that fits like a key into a lock, when the lock changes the key doesn’t fit anymore so remember calves are not used to drinking UHT milk or long life milk they drink raw milk so the more the structure changes the less chance that the rennet will be able to do the job so some shop milk we can use we’ve got to do that little rennet test that I shared with you earlier. Yeah, so I hope that helped you on your way to solving your rennet setting issues in your cheese making. If not, please drop me an e-mail or join our Facebook group at cheese making and dairy science.

Leon the Milkman, all the best

Brief history of American Cheese Making

The history of cheese making in the United States dates back to the arrival of European settlers in the 17th century. The first cheesemakers were of English, Dutch, and German descent. They brought with them their traditional methods for making cheese. Cheese making initially was a way for settlers to preserve excess milk from their cows, but it grew into a profitable industry.

Some historical early American cheesemakers include:

  1. Jesse Williams, considered to be the first commercial cheesemaker in the United States. He began making cheese in the late 1700s in New York and his cheese became popular throughout the northeastern United States.
  2. G.F. Warren, who established a cheese factory in New York in 1851 and is credited with inventing the process for making “brick cheese”.
  3. John J. Smith, who in 1868, began making Limburger cheese in Wisconsin, which helped establish the state as a major cheese producer.
  4. Stephen F. Wilber, who in 1869, established one of the first cheese factories in California.
  5. Joseph F. Steinwand, who in 1885, established one of the first cheese factories in Minnesota.

In the 19th century, the industrial revolution brought new technologies and techniques to cheese making. These developments lead to the mass production of cheese. The invention of the cheese press, for example, made it possible to produce large quantities of cheese in a shorter amount of time. This allowed for cheese production on a larger scale and at a lower cost, making it more accessible to the general population.

Today, the United States is one of the largest cheese producers in the world, with over 900 different types of cheese produced across the country. The most popular cheese types in the USA include Cheddar, Mozzarella, and American.

Cheddar is a hard, sharp-tasting cheese that originated in the English village of Cheddar. It is the most popular cheese in the United States, accounting for over 40% of the total cheese production. Cheddar made from cow’s milk and can age for several months to several years. The aging process gives cheddar its characteristic sharp flavor.

Mozzarella is a soft, mild-tasting cheese that originated in Italy. It is the second most popular cheese in the United States and is mainly used on pizza. Mozzarella made from cow’s milk can be made into a variety of forms, such as fresh mozzarella and low-moisture mozzarella.

American cheese, also known as processed cheese, is a type of cheese made from a mixture of natural cheese and other ingredients. These ingredients could include emulsifiers and artificial colors. It is a popular choice for sandwiches and burgers, and has a mild, creamy flavor.

Besides to these three popular types, there are a wide variety of other cheeses produced in the United States. Examples are blue cheese, Colby, Gouda, Feta, and Brie.

The cheesemaking industry in the United States continues to evolve and adapt to changing consumer tastes and preferences. Today, many cheesemakers are producing artisanal and specialty cheeses, using traditional methods and high-quality ingredients. These artisanal cheeses are becoming increasingly popular among food enthusiasts, who appreciate the unique flavors and textures that these cheeses offer.

In recent years, there has also been a growing interest in farm-to-table and sustainable food movements in the United States. This has led to an increase in the number of small-scale cheesemakers using locally sourced milk and other ingredients.

Brief history of cheese making in South Africa

The history of cheese making in South Africa can be traced back to the early days of European colonization in the 17th century. The Dutch and French settlers brought with them their traditional cheese making techniques and knowledge, which laid the foundation for the South African cheese industry.

In the early days, cheese was primarily produced on small-scale farms by individual farmers. The cheese produced was primarily for personal consumption and was not widely available for purchase. However, as the population of South Africa grew, so too did the demand for cheese.

During the 19th century, the cheese industry in South Africa began to expand, with the establishment of large-scale commercial dairy farms. These farms produced a variety of cheese types, including cheddar, gouda, and edam. These types of cheese quickly became popular among South Africans, and they remain popular to this day.

As the 20th century progressed, the South African cheese industry continued to grow and evolve. New technologies were introduced, such as pasteurization and refrigeration, which allowed for the production of a wider variety of cheese types. Additionally, the increasing demand for cheese from both domestic and international markets led to the establishment of large-scale cheese factories.

Today, South Africa is a major cheese producer, with a wide variety of cheese types available on the market. Some of the most popular cheese types in South Africa include cheddar, gouda, feta, brie, camembert and blue cheese.

Cheddar is a hard cheese with a slightly tangy, nutty flavor. It is used in a wide variety of dishes, from sandwiches to casseroles, and is a staple in many South African households.

Gouda is a semi-hard cheese with a nutty, buttery flavor. It is often used in sandwiches and as a topping for crackers and bread.

Feta is a soft, crumbly cheese with a tangy, salty flavor. It is often used in salads, sandwiches, and as a topping for pizza.

Brie is a soft cheese with a creamy, buttery flavor. It is often served as a dessert cheese or used in sandwiches and crackers.

Camembert is a soft cheese with a creamy, slightly mushroomy flavor. It is often served as a dessert cheese or used in sandwiches and crackers.

Blue Cheese is a type of cheese with a distinctive blue veining and a tangy, sharp flavor. It is often used in salads, sandwiches, and as a topping for crackers.

What does the job entail?

A cheese maker’s job typically entails a wide range of tasks that are involved in the process of producing cheese. Some of the main responsibilities include:

Developing and testing new recipes: Cheese makers may work on developing new recipes for different types of cheese, experimenting with different ingredients, and testing the results to ensure that the flavor, texture, and appearance of the cheese meet the desired standards.

Producing cheese: Once a recipe has been developed, cheese makers will use it to produce cheese in large quantities. This will involve a series of steps such as preparing the milk, adding cultures and enzymes, heating, cooling, and salting the milk, cutting and stirring the curds, shaping and pressing the cheese, and monitoring the temperature and humidity during the aging process.

Monitoring and testing: Cheese makers will constantly monitor the cheese throughout the production process, testing it for acidity, moisture, and pH levels to ensure that it is developing properly and meets the desired standards.

Sanitation and safety: Cheese makers must maintain a high level of sanitation throughout the production process to prevent contamination of the cheese and to ensure that it is safe to eat.

Record Keeping: Cheese makers will keep detailed records of the production process, including the recipes used, the ingredients, the quantities produced, and the results of any testing that was done.

Quality control: Cheese makers will be responsible for ensuring that the cheese they produce meets the quality standards set by the company or by regulatory authorities.

Maintenance: Cheese makers may also be responsible for maintaining the equipment and facilities used in the production process, such as cleaning, troubleshooting, and performing routine repairs.

What is an average day at work like?

An average day for a cheese maker can vary depending on where they work and the type of cheese they are making, but there are some common tasks that they will typically perform.

In the morning, a cheese maker will begin by preparing the milk and getting the equipment ready for the cheese making process. This may involve pasteurizing the milk, adding cultures and enzymes, and heating the milk to the correct temperature.

Once the milk is ready, the cheese maker will then begin the process of separating the curds from the whey. This is done by adding rennet to the milk and allowing it to coagulate, and then cutting the curd using a curd knife.

After the curds are cut, the cheese maker will then heat the curds and whey to the desired temperature, which will vary depending on the type of cheese being made. The cheese maker will also need to monitor the acidity and pH of the curds to ensure that they are developing correctly.

After the curds are heated, the cheese maker will then begin the process of shaping the cheese, This can be done by ladling the curds into molds, pressing them, or by salting and aging the curds to create cheese such as cheddar.

Throughout the day, the cheese maker will also be monitoring the cheese as it ages, and may need to turn or flip it to ensure that it is aging evenly. They will also test the cheese for moisture content, acidity, and other factors to ensure that it is developing correctly.

Cheese makers will also spend time cleaning and sanitizing equipment, as well as, recording the details of the production process to keep track of everything they did and if the cheese is developing as per the recipe, it’s quality and quantity.

Depending on the cheese maker’s role and the size of the operation, some cheese makers may also be responsible for packaging and labeling the cheese, which may involve wrapping the cheese by hand or operating packaging equipment.

Finally, some cheese makers may also spend some of their time promoting and selling their cheeses to customers, whether by attending events, trade shows or by building relationships with retailers.

RIP – Danie de Bruyn – 27/12/2021

Oom Danie de Bruyn was ‘n spesiale mens. Ek het eintlik nog uitgesien om hom weer te sien – dit sou nou einde Des 2021 wees of sommer in die eerste week van 2022. Ons het 2 “modes” gehad – of lekker gesels of mekaar ge-ignoreer vir die dag. Ons laaste gesprek: Ek: “Ok, Oom Danie – ek het nou genoeg kak aangejaag vir die dag en gaan nou loop.” Oom Danie:”Ja dis reg, fokof.” Met ‘n smile op sy gesig natuurlik 😉

Fantasiese storieverteller(en hy het baie gehad) en alles uit ondervinding, raadgewer, houer van logika, pH meter vingers en termometer elmboog is maar paar van sy vele talente. Hardkoppige volger van sy eie raad en pad, en as jy hom nie met soliede data verkeerd kan bewys nie, dan bulldozer hy in ‘n rigting sonder stop. As hy van jou gehou het dan het hy en indien nie, dan het hy jou niks tyd gegee nie, behalwe die nou-en-dan verbale hou voor die kop. Komende van die Weskus kon ek dit waardeer. Dit was altyd binne konteks en nie onregverdig. Hy het regtig baie ondervinding van alle fasette van suiwel gehad en dit met trots en liefde gedeel as jy mooi vra. Soms met ‘n toets en baie redenasie, maar altyd met liefde en skewe glimlag. Beterweterig, want hy het regtig beter geweet.

Vir sy vrou en kinders was hy lief, en het baie gepraat oor hoe goed hul doen en dat hulle pad reguit is. Liefde en sterkte aan Tannie Johanna, Rick, Derick and Juanita.

Oom Danie, ek sal ons geselsies mis. Ek waardeer jou bydrae tot my lewe en ek sal jou onthou.

As iemand ‘n storie/fotos van Oom Danie het wat hulle wil deel, kan julle dit vir my stuur by leon@alivingway.com en ek sal by die artikel insluit.

Oom Danie het vir werk opgedaag op 27/12/2021 en het huis toe gegaan nadat hy sleg gevoel het. Ons vermoed hy is daar aan ‘n hartaanval oorlede.
