This document summarizes several non-alcoholic plant-based beverages that are consumed worldwide for their stimulating and refreshing qualities. It discusses the origins, production processes, chemical compositions, and cultural histories of tea, coffee, cocoa, kola, mate, and guarana. The key plants discussed are Camellia sinensis (tea), Coffea arabica (coffee), Theobroma cacao (cocoa), Cola nitida (kola), Ilex paraguariensis (mate), and Paullinia cupana (guarana).
Coffee processing involves harvesting ripe coffee cherries, removing the fruit pulp and mucilage, and drying the beans. There are two main processing methods - wet processing and dry processing. Wet processing involves pulping the cherries to remove the fruit, fermenting the beans to remove mucilage, and sun drying the beans. Dry processing involves sun drying the entire cherry after harvest and later hulling the dried beans to remove the outer layers. Proper processing is important to develop the flavor of the coffee beans before roasting and brewing.

Coffee originated in Ethiopia and was discovered by a goatherd named Kaldi. It spread through the Middle East and Europe via travelers and traders and was introduced to America by Dutch colonists. There are three main types of coffee plants grown for commercial purposes, and coffee is now cultivated in Latin America, Africa, Asia, and the Arabian Peninsula. The process of turning coffee beans into a beverage involves harvesting, curing, roasting, grinding, brewing and various methods at each stage can impact the flavor of the final coffee.
The document discusses green tea and its health benefits. It provides details on the origin, production regions, types of tea including green tea, and the processing and components of green tea. Green tea contains catechins that can decrease blood cholesterol, reduce body fat, prevent cancer and tooth decay, and inhibit high blood pressure due to their antioxidant and antibacterial effects.
This document provides an overview of tea and the tea production process. It defines tea as coming from the Camellia sinensis plant and being prepared by pouring hot water over cured leaves. Herbal infusions made the same way from other plants are called tisanes. The document describes the different varieties of tea plants used, the grading of tea leaves, common tea brands, and the orthodox manufacturing process for black tea which involves plucking, withering, rolling, fermentation, and firing of the leaves. It also briefly outlines the green tea production method in China.
Coffee berries contain coffee beans that are processed through two main methods - the dry method and wet method. In the dry method, berries are sun dried and de-hulled, while the wet method uses pulping and fermentation to remove the fruit matter around the beans. Roasting is then required to develop the beans' flavor and aroma, during which various physical and chemical changes occur like swelling, color change, and development of volatile compounds. The manner and level of roasting impacts the specific flavor characteristics produced.

The history of coffee dates back to the 10th century in Ethiopia. There are two main types of coffee beans - Arabica and Robusta, which differ in taste, growing conditions, and price. Kopi Luwak from Indonesia is considered the most expensive coffee due to its uncommon production process involving the Indonesian palm civet.
Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain flowering plants in the Coffea genus. From the coffee fruit, the seeds are separated to produce a stable, raw product: unroasted green coffee. The seeds are then roasted, a process which transforms them into a consumable product: roasted coffee, which is ground into fine particles that are typically steeped in hot water before being filtered out, producing a cup of coffee. Let's get overlook to this coffee from this presentation.

Beyond the Advance Presentation for By the Book 9John Rodzvilla
In June 2020, L.L. McKinney, a Black author of young adult novels, began the #publishingpaidme hashtag to create a discussion on how the publishing industry treats Black authors: “what they’re paid. What the marketing is. How the books are treated. How one Black book not reaching its parameters casts a shadow on all Black books and all Black authors, and that’s not the same for our white counterparts.” (Grady 2020) McKinney’s call resulted in an online discussion across 65,000 tweets between authors of all races and the creation of a Google spreadsheet that collected information on over 2,000 titles.
While the conversation was originally meant to discuss the ethical value of book publishing, it became an economic assessment by authors of how publishers treated authors of color and women authors without a full analysis of the data collected. This paper would present the data collected from relevant tweets and the Google database to show not only the range of advances among participating authors split out by their race, gender, sexual orientation and the genre of their work, but also the publishers’ treatment of their titles in terms of deal announcements and pre-pub attention in industry publications. The paper is based on a multi-year project of cleaning and evaluating the collected data to assess what it reveals about the habits and strategies of American publishers in acquiring and promoting titles from a diverse group of authors across the literary, non-fiction, children’s, mystery, romance, and SFF genres.

The Jewish Trinity : Sabbath,Shekinah and Sanctuary 4.pdfJackieSparrow3
we may assume that God created the cosmos to be his great temple, in which he rested after his creative work. Nevertheless, his special revelatory presence did not fill the entire earth yet, since it was his intention that his human vice-regent, whom he installed in the garden sanctuary, would extend worldwide the boundaries of that sanctuary and of God’s presence. Adam, of course, disobeyed this mandate, so that humanity no longer enjoyed God’s presence in the little localized garden. Consequently, the entire earth became infected with sin and idolatry in a way it had not been previously before the fall, while yet in its still imperfect newly created state. Therefore, the various expressions about God being unable to inhabit earthly structures are best understood, at least in part, by realizing that the old order and sanctuary have been tainted with sin and must be cleansed and recreated before God’s Shekinah presence, formerly limited to heaven and the holy of holies, can dwell universally throughout creation

every week.
• Only place where tea from every tea
producing country will be on sale.
• Tea tasting is a vital part of setting prices
and buying and selling
– Autumnal, pungent or brisk
– Weedy or chesty
6. Countries involved

buds called as “flush” are picked (high
concentration of caffeine)
• Can be picked every 10 -14 days
10. Process
• Chinese tea – Green tea, flowery flavor and light
• Assam tea – Black tea, “heavy” stronger
• Black tea: Process involves
– Withering by blowing air through the leaves that are in troughs to
reduce water content and enzymatic release of aroma
– Fermentation – by rolling leaves and leaving them in a warm
damp condition to rupture cells, allow oxidation of phenolics and
turn cooper color
– Finally dry or fire the tea leaves with hot air to remove excess
water, gives black color
• Green tea: Freshly picked leaves are steamed and dried
without the withering stage and thus retain a faint but
distinctive ‘grassy’ taste, and their green color.

during the reign of Shen Nung (The Divine
healer) during 2737 BC
• Japanese Tea Ceremony: During Sung Dynasty
(960 -1120) ritualized the preparation and
drinking of tea as contemplation. This was taken
to Japan
– The tea ceremony according to Zen Buddhism is a
means of achieving the ideal state of perfect harmony
and tranquility
– Still very important; Japanese girls attend special
classes; families spend large amounts of money to
built tea huts and buy tea utensils.
13. Stories of Tea

houses
18. The plant
• Coffea arabica (arabica coffee) – 75%, C.
canephora (robusta coffee) 24% and C.
liberica are grown commercially
• Family - Rubiaceae
• Three varieties are known
– Arabica
– Robusta
– Liberica
19. Morphology
• Source of coffee is the seed that is part of a fleshy berry (sometimes
called as cherry)
• Grows well at higher elevation. Plants are grown directly from seed.
Harvesting after 3 -5 yrs and will produce coffee for 30 yrs.
• Small tree with glossy, evergreen leaves and white, sweet smelling
flowers
• After fertilization, mature berries turning dark green to yellow then
red.
• Inside the sweet pulpy outer layers are two coffee-seed surrounded
by a delicate silvery seed coat.
• Cannot tolerate frost they are grown in tropical and sub-tropical
countries with an average rainfall of at least 1.9 meters per annum
20. Processing
• After picking berries, mostly by hand, the sweet pulp
which surrounds the coffee beans (really seeds) which
develop inside each cherry – like fruit is removed in one
of two ways.
– Dry process – produces beans sometimes known as ‘hard’,
‘native’, or ‘natural’ in trade
• Dry whole fruit in the sun
• Remove dried pulp and fine endocarp and the silver lining around
the seed
– Wet processing produ ces mild but superior flavor coffee
• Depulped machine
• The parchment is washed and left for fermenting for 12 -24 hrs –
leading to chemical change takes place to give characteristic aroma
and taste
• Beans then dried and the fine endocarp is removed
21. Processing
• Instant coffee making
– Coarsely ground coffee is placed in sealed stainless percolators and
brewed under pressure for several hrs.
– Coffee aroma is added
– The concentrate is either
• sprayed under high pressure through fine nozzles into a very high towers. As
the liquid falls back it dries into powder which is tumbled with steam to form
granules OR
• Freeze dried - Coffee brew is dried into thin sheets which is often cut into
granules. Temperature is then raised under vacuum. This will water is “boiled
–off” without the coffee getting wet. There is no heat damage or loss of
aroma
• Roasting – reduces the moisture and bring out aromatic oils
• Very sophisticated-computer control mechanism is involved
• Varieties: variety of coffee, region it is grown, preparation method
and roasting time
23. Substitutes
• Chicory: Cichorium intybus
– Bittter fleshy taproot are ground and roasted
for use either alone or miced with coffee
• Fig: Ficus carica
– Roasted and ground, Austrian and Bavarian
coffees are well known for this addition
• Dandelion: Taraxacum officinale
– Roots have stimulant and tonic but o caffeine
25. Cocoa

seeds of the cocoa tree
• A native of Mexico and found in South American
rainforest
• It was chief drink of the Aztecs and other native
Americans
• It was part of the diet of the plumed serpent God
Quetzalcoatl.
• Cocoa beans were used as currency by Aztecs
• The use of cocoa by other than natives is of
recent origin
26. Cocoa
• Theobroma cacao (meaning food of the
Gods)
• Family - Sterculeaceae
• It is a small tree 15 – 25 ft, with numerous
branches. The flowers and fruits re borne
directly on the tree trunk.
• Mature at 4 – 5yrs. It flowers throughout
the year, so one gets several crops
annually
27. Cocoa
• Source of cocoa is the seeds
• The fruit is a large pod with mucilage pulp and 40 – 60 seeds
• The pulp and seeds are scooped out of the fruit, cured and usually
fermented
– The seeds are piled in heaps in sweating boxes (houses or vats) for
several days.
– The beans become brownish, lose their bitter taste and develop aroma
– They are then wasted and dried and polished to remove any dry pulp
– The seeds are roasted in iron drums to develop flavor and increase the
fat and protein content and lower tannins
– The beans are passed under roller to remove the shells
– The seeds are finally ground to an oily paste – the bitter chocolate
• Sweet chocolate – by adding sugar and various spices
• Milk chocolate – milk, sugar and other spices
• Cocoa – 2/3rd fat is removed and the residue is powdered
• The oil is cocoa butter
28. Chemistry
• Contains caffeine alkaloid called theobromine (1 -3%) –
the stimulant
• Caffeine (.2 – 3%)
• It also has fat (35-40%) and starch (15%)
• It also contain phenyl ethylamine, a natural
amphetamine found in human brain, which induces
feeling of euphoria
• The level of this is claimed, decrease when one is in
love-sick – explaining the craving of chocolate as a
solace at such times
• Also has reputation as an aphrodisiac and Casanova is
said to prefer this as an inducement to romance
30. Kola
• Cola nitida (Sterculiaceae)
• Native of west Africa
• Seeds contain caffeine and kolanin – a
cardiac stimulant
• Coco-cola – has kola and cocoa; now
cocoa leaf extract and caffeine is used
32. Mate and guarana
• Mate – Ilex paraguariensis
– Leaves are used after drying over fire and crushed
into coarse pieces
– Traditionally drunk from a gourd. Has hot water and
mate mixed, a straw is used.
• Guarana – Paullinia cupana
– Caffeine rich seeds are used.
– Seeds are roasted and crushed with cassava flour
into a paste that is formed into rods
– A glass of guarana is made by scrapping the cylinder
and mixing it with water
