I. Nneɛma a Wɔhyehyɛ ne Nneɛma a Ɛwɔ Honam mu Nneɛma
Nneɛma atitiriw a wɔde yɛ kɔfe dua bi ne:
1.Instant coffee powder: Ɛma kɔfe dɛ ne hua titiriw na ɛtaa yɛ freeze-dried anaasɛ spray-dried ma ɛyɛ kɛse solubility.
2.Sweeteners ne emulsifiers: Te sɛ asikre, asikre ananmu, anaasɛ non-nufusu creamer, sesa dɛ na ɛma ɛyɛ mmerɛw bere a wɔapete akyi.
3.Binders: Te sɛ maltodextrin anaa hydroxypropyl methylcellulose (HPMC), hwɛ hu sɛ kɔfe dua no bɛyɛ bere a pressing adeyɛ no na apete pɛpɛɛpɛ bere a wɔde ahyɛ nsu mu.
Wɔde nhyɛso kɛse mia saa nneɛma yi mu ma ɛyɛ poma a ɛyɛ den. Ne density ne porosity nya ne dissolution rate so nkɛntɛnso tẽẽ. Sɛ nhwɛso no, ade a ɛwɔ abon mu ma nsu kɔ mu ntɛmntɛm, bere a ɛsɛ sɛ ade a wɔde kyekyere nneɛma dodow a wɔde di dwuma no kari pɛ wɔ sɛnea ɛyɛ den ne sɛnea ɛtumi nwura mu no.
II. Nnyinasosɛm ne Ɔkwan a Wɔfa so Yɛ Nneɛma a Wɔsɛe no
Kɔfe nnua a wɔpete no gyina nea ɛtrɛw ne nea ɛpete so:
1.Nsuo a ɛkɔ mu: Sɛ nsuo a ɛyɛ hyeɛ anaa ɛyɛ nwini di kɔfe dua no ani a, nsuo nam ntini a ɛyɛ adwuma so hyɛn ntini a ɛwɔ mu no mu, na ɛma kɔfe a wɔayam no ntɛm ne nneɛma afoforo a ɛtumi nwura mu no tew.
2.Molecular diffusion: Dissolved kɔfe molecules diffuse esiane concentration nsonsonoe, yɛ pɛpɛɛpɛ solution. Ɔhyew a ɛkɔ soro ma molecule ahoɔden a ɛkɔ so no yɛ kɛse na ɛma ɛpete ntɛmntɛm (sɛ nhwɛso no, nsu a ɛyɛ hyew taa tew kɔfe dua koraa wɔ sikɔne 5-10 mu).
3.Suspension ne emulsification: Sɛ creamer anaa ngo nneɛma wɔ hɔ a, emulsifiers siw particle settling na hwɛ hu sɛ ɛyɛ dɛ a ɛyɛ mmerɛw.
Ɛfata sɛ yɛhyɛ no nsow sɛ ebia kɔfe nnua a ɛyɛ nwini-nsu a ɛtumi nwura mu no wɔ nneɛma foforɔ a ɛma nsuo yɛ adwuma (te sɛ carrageenan) a ɛbɛtew nsuo ani nhyɛsoɔ so na ama nsuo a ɛyɛ nwini no ayɛ yie wɔ ɔhyeɛ a ɛba fam mu.
III. Nsɛm a Wɔde Di Dwuma ne Mfaso a Ɛwɔ So
Mfiase no wɔyɛɛ kɔfe nnua sɛnea ɛbɛyɛ a wobedi ɛyaw a ɛwɔ kɔfe a wɔde di dwuma ntɛmntɛm a wɔde di dwuma wɔ amanne kwan so a ɛde ne ho to nkankyee anaa nneɛma a wɔde kyekyere nneɛma so no ho dwuma. Mfaso a ɛwɔ so no bi ne:
Wobetumi de akɔ: Wɔde ahyɛ mu mmiako mmiako, na ɛfata sɛ wɔde di dwuma wɔ abɔnten, wɔyɛ adwuma, anaa wɔde tu kwan.
Ready-to-dedi dwuma: Nsusuwii nkuruwa anaa nnwinnade a wɔde kankan biara ho nhia; fa gu nsu mu na nom kɛkɛ.
Standardized Taste: Mfiridwuma mu nneɛma a wɔyɛ no na ɛhwɛ nneɛma a wɔde yɛ aduan no nsusuwii so, na ɛhwɛ hu sɛ dua biara yɛ dɛ bere nyinaa.
Afei nso, nneɛma foforo bi (te sɛ kɔfe nnua a wɔde probiotics anaasɛ nitrogen cold brew mfiridwuma) atrɛw wɔn dwumadi mu bio, te sɛ bere a wɔde sie a wɔtrɛw anaasɛ sɛnea wɔyɛ kɔfe a wɔayam no foforo no pii ho mfonini.
IV. Anohyeto ne Nkɔso a Ɛkɔ So
Ɛwom sɛ kɔfe nnua yɛ nea ɛyɛ mmerɛw na ɛyɛ adwuma yiye de, nanso mpɛn pii no, sɛnea ɛyɛ dɛ no sua sen kɔfe a wɔayam no foforo de, na asikre ne nneɛma a wɔde ka ho dɔɔso wɔ nneɛma bi mu. Daakye nkɔso akwankyerɛ betumi ayɛ:
Nnuru a wɔde ka ho a ɛba fam-asikre/ɛnyɛ-aduru: adidi ma akwahosan-adetɔfo a wɔn ani da hɔ;
Mfiridwuma titiriw a wɔde yɛ nsã a ɛyɛ nwini: ɛma nsuonwini a wɔpete no dɛ yɛ papa;
Nneɛma a nneɛma a nkwa wom sɛe: nneɛma a atwa yɛn ho ahyia a ɛbɛtew so.
Sɛ yɛbɛbɔ no mua a, kɔfe dua no nya kɔfe a wɔnom no mu osuahu a ɛba fam koraa denam honam fam nyansahu ne nneɛma a ɛpaapae mu ahoɔden a ɛka bom no so. Ne nnyinasosɛm ne nkɔso akwankyerɛ kɔ so ma wɔyɛ nneɛma foforo wɔ aduan a ɛyɛ mmerɛw ho mfiridwuma mu.
