 0 foreword  
 
Cape gooseberry is a short shrub that reaches height of 50 to 100 cm and can 
spread up to 4 meters wide. This crop produces a fruit called a berry that is 
commonly bright yellow in colour when ripe but white, green, or even red types  
exist.  The fruits con tain numerous small seeds per fruit ranging between 100 
to 300 seed s. 
Gooseberry is sweet, slightly tart taste and is a good source of vitamins and 
minerals . 
 
This Tanzania Standard was prepared in order to provide guidance to 
gooseberry producers and trad ers as well as regulators, and to ensure safety 
and quality of the produce.  
In the preparation of this Tanzania Standard considerable assistance was 
derived from:  Codex Alimentarius CXS 226 -2001  Standard for Cape 
gooseberry.   
 
In reporting the results of a  test or analysis made in accordance with this 
standard, if the final value observed or calculated is to be rounded off, it shall 
be done in accordance with TZS 4 (see clause 2).  
 
1 Scope  
 
This standard specifies  quality and safety requirements, methods of sampling 
and test  of cape gooseberries grown from Physalis peruviana  (L.), of the 
Solanaceae  family, to be supplied fresh to the consumer . Cape gooseberries 
for industrial processing are excluded.

 4 Requirements  
 
4.1 General requirements  
In all classes, subject to the special provisions for each class and th e tolerances 
allowed, the cape gooseberries shall be: 
 whole, with or without calyx;  
 sound ; 
 clean ; 
 practically free of pests affecting the general appearance of  the produce;  
 practically free of damage caused by pests;  
 free of abnormal external moisture, excluding condensation following 
removal from cold storage;  
 free of any foreign smell and/or taste;  
 firm; 
 fresh in appearance;  
 with a smooth and shiny skin ; 
 
If the calyx is present, the peduncle shall not exceed 25 mm in length  
 
4.1.1  The cape gooseberries shall have reached an appropriate degree of 
developm ent and ripeness account being taken of the characteristics of the 
variety and the area in which they are grown.  
 
The development and condition of the cape gooseberries shall be such as to 
enable them:  
- to withstand transport and handling; and  
- to arrive in satisfactory condition at the place of destination.  
 
4.1.2 Maturity Requirements  
The maturity of the cape gooseberry can be visually assessed from its external 
colouring, which changes from green to bright yellow , orange  or red depending 
on the cultivar as the fruit ripens. Its condition can be confirmed by determining 
total soluble solids.  The soluble solids content should be at least 14.0°Brix.  
A change in colouring of the calyx is not indic ative of ripening of the fruit.  
 
4.2 Classification  
Cape gooseberries are classified in three classes defined below, regardless of 
size and colour:

chara cteristic of the variety and/or commercial type. They shall be free of 
defects, with the exception of very slight  superficial defects, provided these do 
not affect the general appearance of the produce, the quality, the keepi ng 
quality and presentation in the package.  
 
4.2.2 Class I  
Cape gooseberries in this class shall be of good quality. They shall be 
charac teristic of the variety and/or commercial type. The following slight defects

produce, the quality, the keeping quality and presentation in the package:  
- slight defects in shape;  
- slight defects in colouring;  
- slight skin defects.  
 
The defects shall not, in any case, affect the pulp of the fruit.  
 
4.2.3 Class II  
This class includes cape gooseberries which do not qualify for inclusion in the 
higher classes, bu t satisfy the general  requirements specified in clause 4.1. The 
following def ects may be allowed, provided the cape gooseberries retain their

appearance and presentation:  
- defects in shape;  
- defects in colouring;  
- skin defects;

fruit. 
 
The defects shall not, in any case, affect the pulp of the fruit.  
 
4.3 Provisions concerning sizing  
Size is determined by the maximum diameter of the equatorial section of the 
fruit, with a minimum diameter of 15mm, in accordance with Table 1

satisfying neither the requirements of the class nor the general  requirements, 
with the exception of produce affect ed by severe bruising, rotting or any other

number or weight of fruit with small healed cracks covering an area greater than 
5% is accepted in this class.  
 
4.4.2 Size tolerances  
For all classes, 10% by number or weight of cape gooseberries corresponding  
to the size immediately above and/or below that indicated on the package.
