Glossary
Not
every single piece of interesting or useful information can be
contained in the lectures of this course. The digital format of this
course however, makes it easy to provide and link extra information in a
glossary. We hope you enjoy reading through the glossary entries and
make good use of the treasures we have 'hidden' here.

HanzaHanza (Boscia senegalensis) is a traditional foodplant, originating from Sahel region in West Africa. Hanza is a shrub that produces clusters of berry-sized fruits. Fruits are ready for human consumption at the beginning of the rainy season, when most crops are just being planted, and there is little other food available. Fruits can be consumed raw and cooked. Raw fruits initially contain a sweet pulp that then dries out to a sugary solid, difficult to separate from seed. Fruits are often cooked prior to consumption. Juice can also be extracted and boiled down into a butter-like consistency that can be mixed with millet and milk to make cakes. In Sudan, the fruit is fermented into a beer. The seeds of B. senegalensis are also important sources of nutrition, especially during times of famine. To gain access to the seeds, fruits are dried in the sun, pounded to remove the outer seed coat and soaked in water for several days, changing the water every day. The seed soaking process, also known as debittering, is essential to remove bitter and potentially toxic components. Seeds are usually cooked prior to consumption. Cooked seeds are texturally similar to a chickpea and can be used as a cereal substitute in stews, soups and porridges. Additionally, seeds can be re-dried and stored for later use or ground into a flour that can be used to make porridge. Roasted seeds can also serve as a substitute for coffee.

HazardA biological, chemical or physical agent in, or condition of, food with the potential to cause an adverse health effect. | |
Hazard analysisThe process of collecting and evaluating information on hazards, and conditions loading to their presence, to decide which are significant for food safety and therefore should be addressed in the HACCP plan. | |
Heat denaturationSee also Denaturation and Acid denaturation. Many proteins are strongly effected by heat, causing denaturation. Meat consist to about 20% of proteins, like e.g. myosin and collagen.
They undergo substantial structural changes at temperatures between 57°C
to 75°C, which impacts the texture, water holding capacity, and
shrinkage of meat. On the one hand these changes make meat more easily
digestible, on the other hand the water-holding capacity is reduced.
Therefore, resting a steak after cooking allows some of the water to
find new interactions with proteins, resulting in less juice leaking out
when the steak is cut. Casein, a protein in milk is exceptionally stable to heat, which makes it possible to boil and even pasteurize milk without causing coagulation. The protein beta-lactoglobulin, however coagulates at boiling temperatures and forms the characteristic protein skin on top of boiled milk.

High pressure processingA technological process that uses high pressure to destroy microorganisms and enzymes whilst retaining food quality. | |
HireThe act of giving someone a job. The term can also be used to describe renting a piece of equipment. | |
Hockey stick growthA sudden and sharp increase in growth after an initial period of losses.
For startups, this often occurs at the point when startup expenses
shrink and revenues increase. | |
