Reading the bitterness

Chenpi (aged mandarin peel) recorded as being of the same cultivar, origin, season, and initial processing, aged for 2, 10, and 25 years, was compared by 12 experienced assessors on a 6-point scale. The longer-aged groups were higher in bitterness, astringency, sweetness, and richness, and lower in sourness (each p<0.05). However, this is a study that cross-sectionally compared stored products of different ages, and there is no statement that a single batch was tracked for 25 years. The methods for sampling and presenting the samples for human evaluation are also not specified in the text.

The same 3 age groups were also examined with an electronic tongue. In the liquid obtained by steeping 3.0 g of chenpi in 200 mL of boiling water for 3 minutes, removing it, and steeping it again in another 200 mL for 3 minutes, the bitterness sensor response placed the 2-year and 10-year products in the same significance-letter group, with the 25-year product in a separate, higher group (p<0.05). This is an instrument response, not the bitterness strength itself as perceived by humans. It does not show a difference between the 2-year and 10-year products, or an effect of storage duration alone.

    Checked for this overview: Supports the same cultivar, same origin, same season, and same initial processing; the 2/10/25-year ages; the 12 assessors; the 6-point QDA; the direction of the taste changes with p<0.05; and the limitations that this is a cross-sectional comparison with no statement of tracking and no stated presentation method. / Supports the electronic-tongue steeping of 3.0 g in 200 mL for 3 minutes, repeated twice; the bitterness-response significance-letter groups (2-year/10-year group a, 25-year group b); and the limitations that this is not human sensory data and does not establish storage duration alone as the cause.

Sensory (2)

chenpi aging shows the sensory response When 12 assessors evaluated Citrus reticulata “Chachi” aged for 2, 10, and 25 years on a 6-point scale, the longer-aged groups were higher in bitterness, astringency, sweetness, and richness, and lower in sourness (each p<0.05).supported

Scope: Xu et al. 2025; QDA of 3 aging-duration groups recorded as being of the same cultivar, same origin, same season, and same initial processing.

Note: This is a cross-sectional comparison of age groups, with no statement that the same lot was tracked. The specific sampling and presentation methods for the human sensory samples are not specified in the Methods, and the 3 g/200 mL electronic-tongue condition is not carried over to it.

In QDA by 12 assessors, the longer-aged groups (2, 10, and 25 years) were higher in sweetness, bitterness, astringency, and richness, and lower in sourness (p<0.05). There was no significant change in sweet aftertaste, umami, or saltiness.
Limitations: This is a cross-sectional comparison of age groups, with no statement that the same lot was tracked. The specific sampling and presentation methods for the human sensory samples are not specified in the Methods. The figure does not give an exact numerical table of the mean values. Panel age is not consistent between the Methods and the Ethics statement, so age is not used in the claim.

chenpi aging — observed together with: When the 2-year, 10-year, and 25-year products were extracted in hot water and measured with an electronic tongue, the bitterness sensor response placed the 2-year and 10-year products in the same significance-letter group, with the 25-year product in a separate, higher group (p<0.05).supported

Scope: Xu et al. 2025; electronic-tongue measurement of a liquid obtained by steeping 3.0 g in 200 mL of boiling water for 3 minutes, 2 times.

Note: This is an instrument sensor response, not intensity as perceived by humans. No significant difference is shown between the 2-year and 10-year products. This is a cross-sectional comparison of 3 age groups and does not establish storage duration alone as the cause.

The electronic tongue's bitterness response placed the 2-year and 10-year products in the same significance letter group a, with the 25-year product in a higher group, letter b (p<0.05).
Limitations: This is an electronic-tongue sensor response, not human sensory data. No significant difference is shown between the 2-year and 10-year products. This is a cross-sectional comparison of age groups, with no statement that the same lot was tracked, and the storage conditions and number of independent samples are not clear from the Methods text.

How processing and cooking change it (1)

Chenpi is produced through: chenpi agingsupported

Scope: Chenpi (Citri Reticulatae Pericarpium)

Aging is described as "a complex biotransformation process...with a minimum required duration of 3 years." The source also states that "the 'older, the better' quality attribute is closely linked to the progressive enrichment of phenolic acids." It also references studies of products aged 5 to 30 years.
