Oolong and instant tea processing
This presentation summarizes the processing of oolong tea and instant tea. It begins with an introduction to tea and its various types based on processing. It then describes the key steps in oolong tea processing including plucking, withering, shaking, panning, rolling and drying. Health benefits of oolong tea are also highlighted. Instant tea processing involves extracting tea liquor from processed leaves followed by concentration, de-creaming and drying. The presentation concludes by noting oolong tea's intermediate qualities between green and black tea and recommending its use for weight loss.
Methods of manufacturing and fermentation of tea
This document discusses the two main methods of manufacturing tea - Orthodox and Unorthodox (CTC). The Orthodox method preserves the integrity of whole tea leaves through rolling, resulting in complex flavors. The Unorthodox/CTC method shreds leaves for tea bags. It also describes the fermentation process of tea as an oxidation rather than microbial process, changing catechins into flavors. Key steps are withering, rolling, oxidation/fermentation, sorting and drying. Factors like temperature, humidity and aeration influence fermentation quality.
Tea manufacturing process part 1
Tea is made from the leaves of the Camellia Sinensis plant. The process begins with plucking the leaves by hand. The leaves are then withered to reduce moisture content. Next, the leaves are rolled or twisted to rupture cells and promote oxidation. The leaves then undergo fermentation where enzymes cause oxidation reactions that produce compounds responsible for the color and flavor of black tea. Temperature and humidity are carefully controlled during fermentation. The leaves are then dried and processed into various tea products.
Manufacturing of Instant Tea
Instant tea can be produced from black, green, or oolong tea through extraction, concentration, and drying processes. The manufacturing process involves extracting tea solids through hot water extraction. The extracted liquid is clarified through decanting and de-creaming to remove insoluble particles. Aroma compounds are stripped from the extract before concentration in evaporators. The concentrated extract is blended, dried through spray drying, and packaged. Instant tea powder is widely used in tea premixes and food formulations.
CHEMISTRY OF TASTE AND AROMA COMPOUNDS IN TEA AND COFFEE
- Tea and coffee contain many chemical compounds that influence their taste and aroma. Tea is derived from the Camellia sinensis plant, while coffee comes from coffee beans of the Coffea plant.
- Both contain antioxidants and caffeine. Their complex flavors come from hundreds of volatile compounds produced during processing as the leaves/beans are dried, fermented, and roasted.
- The main tastes detected on the tongue are sweetness, bitterness, sourness, saltiness, and savory umami. Different compounds influence each taste, like sugars for sweetness and caffeine for bitterness.

Green tea processing
Green tea processing involves several steps including plucking, enzyme deactivation through steaming, rolling, and drying. Traditional drying methods include sun drying and shade drying but modern methods like convection drying, microwave drying, infrared drying, and hybrid processes are now commonly used. Microwave drying provides uniform and rapid heating but can damage tea leaves. Infrared drying also allows for fast, controlled, and uniform heating without contact. Comparison of drying methods found microwave vacuum drying produced the highest quality tea based on sensory attributes and rehydration ratio, though conventional methods can better retain certain nutrients like amino acids. Overall, modern methods can significantly reduce drying time but require more capital investment.
Process flow chart tea processing
The document describes several processes for manufacturing green tea. In general, the key steps are:
1) Plucking or harvesting of young green tea leaves.
2) Fixing enzyme activity through steaming or pan firing.
3) Rolling leaves to shape them.
4) Drying leaves through multiple stages to reduce moisture content to around 3-5%.
Specific processes may incorporate additional steps like withering, cutting, sorting, and final roasting. Methods can involve different machines, temperatures, times and numbers of rolling and drying stages to produce different types of green tea.

Types of Tea and their Processing Methods
It includes various types of tea i.e White tea (Unfermented and Unoxidised) ,
Green Tea (Unfermented and Unoxidised)
Oolang Tea (Semi-fermented)
Black Tea (fully Fermented and Oxidised)
It also includes all the steps involved in the processing of these teas.
Processing Of Tea
Tea processing is the method in which the leaves from the tea plant Camellia sinensis are transformed into dried leaves for brewing tea.
The categories of tea are distinguished by the processing they undergo. In its most general form, tea processing involves different manners and degrees of oxidation of the leaves, stopping the oxidation, forming the tea and drying it.
The innate flavor of the dried tea leaves is determined by the type of cultivar of the tea bush, the quality of the plucked tea leaves, and the manner and quality of the production processing they undergo. After processing, a tea may be blended with other teas or mixed with flavourants to alter the flavor of the final tea. When producing black and oolong teas there is an additional purpose of processing: to encourage oxidization, which further develops flavor and aroma compounds.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
